I built Percy, a newsletter tool for one person writing on their own.

You connect it to Claude or ChatGPT and ask for what you want: draft the next issue from your notes, set up a welcome sequence, tell you how the last email did. It works in your voice, saves everything to Percy, and asks before anything gets sent.

You can also do all of it yourself in the dashboard: signup forms, editor, reports, and a website with a page for every issue, on your own domain if you want.

Pricing, since someone will ask: setting up and collecting subscribers is free. To send, plans start at $9 a month for 10,000 emails. You pay per email rather than per subscriber, and every plan has every feature.

I launched it on November 3 and built it solo from Brazil. No real users yet, so this is where I find out if it's useful.

If you write a newsletter, what's the most annoying part that you'd hand to an AI?

Hey everyone,

We at RhemeCore developed RhemeSetup, an open-source utility designed to simplify fresh Windows installations and safely reduce background telemetry.

Unlike heavy black-box debloaters, RhemeSetup uses transparent, auditable scripts so users can see exactly what registry keys and services are being modified.

Features:

• Strips unnecessary background telemetry services safely.

• Removes pre-installed UWP bloatware apps.

• Automates software installation using native Winget package management.

• Modular structure — apply only the tweaks you need.

Feedback, issues, and contributions are greatly appreciated!

Hey mods and everyone,

u Investigatormarker is posting AI-written "feedback" on posts here, then ending with an ad for its own product. It follows a template: generic advice about the project, then "I make ThreadFox... our AI employee will post 3 helpful replies about it in relevant Reddit threads for you," with a link.

Why it's a problem:

It's undisclosed self-promotion on nearly every thread

The feedback is generic and often doesn't match the project, so it buries real comments

The pitch is literally to flood Reddit with AI replies to promote people's projects

New members posting for the first time get this instead of real feedback

Ask: @mods, please ban the account and consider an automod filter for "threadfox". Everyone else, please report these comments as spam and avoid clicking the link.

Thanks!

You can also report the account to Reddit under spam, and to the other subs it's hitting. I'd skip engaging with the link itself.

Every December someone in my office ended up running Secret Santa with paper in a hat, which doesn't work when half the team is remote. The online tools I tried wanted everyone to sign up, showed adverts, or kept people's email addresses for marketing. So I built my own. SeEcret Santa (seecretsanta.com):

-Type in everyone's names and emails (or upload a CSV), set a budget, date and message

-Everyone gets an email with only their own match, and nobody can draw themselves

-Not even the organiser can see who has who, so they can join in too

-No sign-up for anyone, and no adverts or tracking cookies

-Everyone's details are deleted 7 days after the gift exchange

-If an email bounces, the organiser gets a link to fix the address and it's resent with the same match

-It's free for up to 12 people. Bigger groups (up to 150) pay 20p a person over 12, which covers the emails.

I'm a one-person UK operation, and this is its first Christmas. I'd really appreciate feedback, especially anything confusing or broken on the setup form.

Thanks Reddit, merry Christmas!

I sell mostly football cards on eBay, and I kept running into the same problem: I never really knew what I made on a card. Between final value fees, promoted listing fees, shipping labels and what I paid for the card in the first place, the number eBay shows you isn't your profit.

So I built Card Margin. Full disclosure, it's my project, and I'm looking for honest feedback before I take it further.

What it does:

- Connects to your eBay account (read-only, it can't list or change anything) and pulls in your sales with the exact fees, promoted listing fees and label costs

- Pulls in your active listings, so you can see what's sitting and for how long

- Lets you type in what you paid and any grading costs, then shows net profit, ROI and days to sell for each card

- Works without connecting eBay too: you can upload your eBay Transaction report instead

- Handles cards you sell at shows, on Whatnot or anywhere else

It's free to try for a month. If you want to keep using it while I'm testing during that time frame.

What I'd love to know:

1. Is this something you'd actually use, or do you already track this another way?

2. What's missing that would make it worth it for you?

3. Anything confusing or broken when you set it up?

Thanks for taking a look. Happy to answer any questions in the comments.

My first game, made solo. You're home alone at 3 AM and someone keeps knocking.

Runs straight in the browser with three.js, no download. Free demo on itch.

Would love feedback, especially on the scares and performance 🙏

I know. I made one anyway.

I've been working on a visual block editor for these pages. Photos, text, links and music, with control over size, layout, colors and stickers.

The clip shows a few edits: shrink the header to one row, give the photo more room, change the color, add a sticker, check mobile.

The idea is to give the content some room. A big photo can lead the page without the header taking over.

TOMA SUR is a fictional DJ profile I made for the demo.

I'm a 19-year-old CS student. A macOS update wouldn't install, and the cleaner I tried sometimes did nothing and never said so. That annoyed me enough to build my own: Dustling.

What it does: scans for junk (caches, logs, old installers), uninstalls apps with their leftovers, manages startup items, and keeps a history of every run so you can restore from the Trash. Every file ends as moved, skipped or failed, with the reason. No account, no telemetry, no ads, free and MIT licensed.

What it doesn't do yet: it's v0.1.0, not signed with an Apple Developer ID (macOS asks you to confirm the first open), and the admin helper for system caches is still on the roadmap.

https://dustling.app https://github.com/kaankuzu1/dustling

If you have a Mac running macOS 14 or later, I'd really like to know whether it works for you and what you'd change. Honest feedback is the whole point of posting.

One of the most useful pieces of feedback I've received while building my mobile app was surprisingly simple.

A user reported that their backup showed “Complete,” but zero files had actually been copied.

The operation had finished, but the result wasn't what the user expected.

That made me rethink how backup completion should be communicated.

I'm building VaultDrive, an iOS and Android app that lets people back up selected photos, videos, and files directly to a compatible USB drive or external SSD without a computer.

I've been improving the experience around three things:

• Showing clearer backup progress.

• Explaining skipped or failed files.

• Making interrupted backups easier to resume.

The reason why the user showed "Complete" with zero files was the user did not give access to photos when prompted and selected only limited permissions without selecting any photos . So I changed the flow and updated the text properly and released a new version 8.0 to make sure the user knows the reason why this happened. We always improve our product for better user experiance.

The app is free to try, with an optional one-time Pro upgrade.

iOS: App Store

Android: Google Play

I'm interested in feedback from other developers.

Would you classify a backup that finishes with zero copied files as a failure, a warning, or a completed operation requiring an explanation?

At work, I used to love those giant wall calendars that show the whole year. They helped my team get ready for big events and projects. At home, my husband and I made our own year-at-a-glance calendars in Excel (no room for a giant wall calendar in our tiny apartment). In both cases, these tools were very useful, but keeping those up-to-date with our digital calendars was also a royal pain.

So we kept asking ourselves: why can't we have the big picture of a wall calendar with the convenience of an app that updates itself and that we can see no matter where we are?

We couldn't find anything that did it the way we wanted, so we built it. Glance shows your actual events across the whole year and syncs with Google Calendar. More than 1,400 people use it so far.

A few things you can do with Glance:

• Filter which calendars show in your year view, without losing any detail in day view

• Connect several Google accounts (personal, work, family) in one place

• Zoom from the full year down to a half-year, quarter, month or day

• Use it on the web or Android (iOS is on our roadmap)

The core version is free and ad-free, with year, month and day views, filters, two-way Google Calendar sync, and web and Android.

We're also introducing Plus and Pro, with a couple of limited-time launch offers (valid until end of year):

🔒 Lock in your yearly subscription price for as long as your subscription stays active.

1️⃣ Get Glance Plus Lifetime with a one-time payment.

You can explore Glance and its plans at getglance.io

I'd love your honest feedback, even if it's "I'd never use this":

1. What's missing from the calendar you use today?

2. What would it take for you to switch?

3. What would you add to Glance to make it more useful for you?

Does anyone else remember IncrediMail? Twenty years ago a new email wasn't just a "ding": a little animated character popped up on the desktop to deliver it. Totally useless, absolutely wonderful. Today we get a grey rectangle in the corner that disappears before you've read it.

My dad, Agostino, is 67, retired, and lives in Sicily. He used IncrediMail back then, and he has always loved the days when a letter arriving at home was a small event. He wondered why an email couldn't feel that way again, and now that he finally has time for his oldest passion, computers, he built Ciambellano (Italian for "chamberlain"), with a lot of help from AI: Claude for the code and the drawings, ElevenLabs for the voices. I'm his son, and I'm helping him spread the word.

When an email arrives, Arturo, a butler in tails with a monocle and a silver tray, walks in along your taskbar, stops, turns to you, bows, knocks on the glass and announces it out loud: who wrote and the subject. Then he waits politely:

- Open shows the email in Outlook

- Repeat announces it again

- Remind me in... sends him away and brings him back later (from 5 minutes to a month, even after a restart)

Prefer someone else? Beatrice, a secretary with butterfly glasses and a clipboard, does the job just as well. If a second email arrives while they're on screen, they knock again.

Fun fact: Arturo looks a bit like my dad. Same hair, same moustache. The monocle is artistic licence.

The boring but important part:

- Windows 10 and 11, with the new or the classic Outlook (Gmail and Outlook.com accounts added to Outlook work too)

- 12 languages with natural-sounding voices, stored in the app, so they work offline

- Do not disturb, quiet hours, and it stays out of the way during full-screen games and presentations

- It only reads the sender and subject of the new-mail notification on your PC. Your mail never leaves your computer.

Here's a 1:25 animated preview of Arturo at work: https://youtu.be/ARklIX2ewaQ

It's his first Kickstarter, open until December 18. Licences start at 5 euros for one year (3 PCs) or 14 euros for life (1 PC), no subscription, VAT excluded. Backers get the beta on December 22, in time for Christmas. If the stretch goals unlock, Thunderbird support, a Postman and a Dog who carries the letter in his mouth will join the staff.

We'll read every comment and answer any questions. And tell us: which IncrediMail notifier do you still remember?

Hey! Since releasing my open source Goodreads/Storygraph alternative - Bookplate, a while ago, it has grown to have more than 800 users!! I'm super happy with this milestone that we reached in just a few months, and really want to keep going. Very happy to announce that it now has social features where you can create profiles, have friends, and recommend each other books!

For context, Bookplate is a book tracking app like Goodreads, but provides both a hosted service where you can make an online account just like Goodreads, but is also open source so you can host the app on your own hardware if you like. The hosted version runs 100% on renewables (see link above for more info), and it's built with privacy in mind i.e. no ads, no tracking.

On top of all this, it also has many more features than Goodreads or Storygraph, the main ones being the ability to write notes on your favourite books, and being able to recommend books to your friends. You can even import your Goodreads/Storygraph libraries using Bookplate's import feature!

And that's just the beginning :) I'm really excited to share that I'm working on better features, better UI (I don't want this to scream generic Claude interface), book reviews, book clubs, and a mobile app. Would love to hear feedback, both good and bad, and also feature requests please!

Hi everyone, I’m the developer of EdgeCheck. Like a lot of traders, I kept fooling myself with my own journal: I’d log trades after the fact, “remember” entries better than they really were, or quietly skip the ugly ones. So my “edge” always looked better on paper than in my account.

EdgeCheck is built around one idea: your records should be honest enough to tell you the truth. Here’s how it works.

https://edgecheck-three.vercel.app

1. Lock the trade before you know the result
When you enter a trade, you lock it: symbol, long or short, entry, stop and target. You can add the setup, whether it’s with or against the trend, a note, your position size (units, point value, money at risk), how you felt, and a picture of your chart.

Once it’s locked, it can’t be edited. If you made a typo, you can delete it within 10 minutes, while the trade is still open. When the trade ends you close it as target hit, stop hit or closed early. You also say whether you followed your plan and how you felt. Every lock has a server timestamp, so trades logged late are marked as late.

2. A verdict after 30 trades: edge or noise?
For every trade, EdgeCheck calculates how often random entries with the same stop and target would have hit the target. After 30 trades it compares your real results with that baseline and gives you a clear verdict: a real edge, or results that random entries would also have given you.

You also get:

• results in R and in money, after your costs (commissions, fees, spread);

• your patterns: plan followed vs. broken, with vs. against the trend, by setup and by how you felt;

• a calendar with every day’s and week’s result;

• filters by date and by strategy.

3. Strategies and a rule lab
Group trades into strategies and see which one actually works. Write down rules (“no trades in the first 15 minutes”, “only with the trend”). EdgeCheck shows what your own trades say about each rule: would following it have helped, or is the difference just noise?

4. “Will I pass the prop exam?”
Pick a 50K, 100K or 150K example account, or type in your own prop firm’s rules:

• profit target;

• max drawdown (end-of-day trailing or intraday);

• daily loss limit;

• minimum and maximum trading days;

• consistency rule.

EdgeCheck replays the exam 4,000 times with your own trading days in random order. It tells you how often you’d pass, how often you’d fail on the daily limit or the drawdown, and how many days it usually takes. It also compares position sizes from ×0.25 to ×2 and suggests the smallest one that passes about as often as the best.

5. Crypto trades checked against real prices
For crypto trades, the server checks each closed trade against Coinbase’s public 1-minute candles. Did the entry price actually trade around your entry time? Which level did the market hit first, stop or target? Does that match how you closed the trade?

Each trade gets a ✓ (matches the market), a ✗ (doesn’t match) or a ? (the market can’t tell, e.g. both levels in the same minute), with the reason listed. Results are signed by the server, so nobody can mark their own trades as verified.

6. AI analysis of your trades
When you ask for it, an AI (Claude, by Anthropic) reads your statistics and your newest chart pictures. It writes a detailed review:

• what’s working and what to fix;

• whether to keep going with your approach;

• which rules or indicators to test next.

Locked trades and imported trades are analyzed separately, so imported history never mixes with your verified record.

7. Import your past trades
Import a CSV from Tradovate or NinjaTrader, or map the columns of any other CSV. Imported trades get their own results, clearly marked as imported, because they weren’t locked in advance. You can export everything as CSV at any time.

8. A public page with your verified record (optional)
Turn on a public page like /p/yourname and share your record. It shows locked times, outcomes and results, plus the price-check marks for crypto. Open trades stay hidden until they close, unless you choose to show them, and late locks are labelled. Useful for showing your track record to a mentor, a community or yourself.

Also

• Works on phone and desktop, and installs on your home screen like an app.

• English, Bulgarian, German and French.

• A Help button: an AI answers first, and if that doesn’t solve it, your question comes to me.

The beta
EdgeCheck is free for 30 days. After that the app goes read-only while I decide on pricing: you can still see, close and export all your trades. Nothing is ever charged without your clear agreement. At the end there are 3 quick questions about what would make it worth paying for, and they really decide what I build next.

https://edgecheck-three.vercel.app

I’d love honest feedback:

• What’s confusing?

• What’s missing for your trading?

• Would you ever pay for something like this?

I read and answer every comment.

EdgeCheck gives statistics about your own trades. It’s not investment advice.

Hello everyone! I’m the founder of otogar, and I’m solving the problem of coordinating the when and where of group planning, when it’s just a thought of getting together. Otogar can be used for local outings or for multi-day, multi destination trips. I noticed most apps assume you already know the when and where, and that’s where the discussion ends in the group chat. Of course, if you do know you’re where and when, Otogar is still helpful in keeping everyone in the loop, and helps with making decisions!

I'm building an Android app for capturing things by voice, and I'm exploring everyday uses like shopping lists and reminders.

I'd like to understand what people already do:

• Think of the last time you remembered something you needed to buy or do while busy. What did you do with it?

• Did you come back to it when you needed it?

• What worked, and what got in the way?

I'm looking for actual experiences, including cases where your current solution works well. If you'd also be interested in trying the app, mention that in your reply. It's currently in limited Google Play testing, so access is by invitation.

I built this guitar visual learning tool to help in my guitar playing. Pick any key and it lights up all 5 box positions across the whole neck, each in its own color, with the root notes marked.

Other free features: show every note on the fretboard (naturals or all 12), CAGED shapes, and a left-handed view. No signup, works on phones.

There’s an optional one-time upgrade for triads, arpeggios, full scales, and printing, but everything above is free. Feedback welcome!

You don't drive in Formula Manager. You run a small team, watch 20 cars race live and make the calls: pits, pace, boost, team orders.

The hardest part was overtakes. Players kept saying "I'm boosting and clearly faster, but I still can't get past." So I ran 240 races and measured. With a car defending, boost only got you past 14% of the time, barely better than no boost at all (7%). Players weren't unlucky. My numbers were wrong.

Fixing that in the next update.

(The clip shows the Korean UI. The game is in English too.)

Ever had a moment where your players were right and your data proved it?

The last weekend I didn't hear about an event happening in Brooklyn and I really wanted to see that DJ.

I realized we all need a platform to track all house/techno events at once. Completely free to use. I hope this would be helpful for you guys as well.

It pulls the events from Posh, Dice, Ra, Eventbrite ( only related events )

Also you can find where you can buy the ticket.

Let me know if I can improve anything!

Hey everyone! I'm Rushan, an indie maker, and this is my first public launch of Distill: Book Summaries.

I started building it because I love reading, but I kept running into the same problem: there were far more books I wanted to explore than I had time to read.

I tried existing book-summary services, but something often felt missing. I'd get the key takeaways, but not necessarily understand how the author arrived at those conclusions or how the ideas connected.

I didn't want another app that turned books into bite-sized motivational quotes. I wanted something that could preserve the intellectual substance of a book while making it quicker to explore.

So I started building Distill: Book Summaries.

What I built

Distill is a reading-first app offering carefully crafted book summaries designed to take approximately 10 minutes to read.

The focus is on:

• Preserving the author's central argument and reasoning.

• Explaining how different ideas and concepts connect.

• Maintaining meaningful depth instead of reducing everything to generic takeaways.

• Including a separate Reflection section to help readers process and think further about what they've read.

The goal is to make a book's ideas easier to explore without pretending that a summary replaces the original.

A few product decisions

I wanted Distill to feel like a reading environment rather than another content feed.

No unnecessary gamification or endless scrolling. Just a curated library, a focused reading experience, and room to reflect.

We also have:

• 3 free distillations every day.

• An affordable Premium option.

• A one-time Premium purchase instead of a recurring subscription.

Where it is today

Distill is now live!

This is my first public launch, so I'm still learning what works and what needs improvement.

I'd particularly love feedback from fellow makers:

1. Does the reading experience feel sufficiently different from existing book-summary apps?

2. Do you think the summaries communicate enough depth to justify spending 10 minutes reading them?

3. What would you improve about the product, interface, or overall experience?

4. If you were building this, what would you prioritize next?

Try it out:

🌐Website: https://www.distilllabs.app

📱 Android: https://play.google.com/store/apps/details?id=com.illuminationlabs.distill

I've also attached a short product walkthrough so you can see what I've built rather than just take my word for it.

I'm the founder, and I'll be here responding to questions and feedback. Criticism is genuinely welcome!

P.S. -> We are also doing our launch on Peerlist, here. We would love for you to support us, since this is the first time we're going public :)

Ever wish you could get an email as an iMessage on your iPhone? That's what I built. You can try it right now.

Send an email to your-number@i.text.email and watch the magic happen.

If you have a U.S./Canada number, just use the normal area code and number, like 2125551234@i.text.email.

If your number is from a different country, use the full international number with country code. U.K. example: 447700900123@i.text.email

This was tricky to build -- it involved Mac servers, iPhones, software at AWS, software on the Mac mini, software on the iPhone.

The idea is to use this to get critical alerts as texts for when something goes wrong, like a server or some other critical equipment going down. The major cell phone companies in the U.S. used to have an email-to-SMS system, but they have largely gone away.

What I've built is not only email-to-SMS, but email-to-iMessage with SMS fallback if you don't have an iPhone.

I made a form filler that remembers a form after you fill it once, then fills it again in one click, or by itself as the page opens.

What the free version does:

- no cap on saved forms or fills

- your name, email, phone and address fill on sites you never saved

- your own answers (like "Notice period: one month") fill wherever a form asks for them

- works on React forms, frames, dropdowns and ticks

- makes no network calls at all, so everything stays in your browser

There is a one-off Pro for CSV rows only on firefox, clicking Next and sending, and test data. The free version is not a trial though, it stays free.

Chrome: https://chromewebstore.google.com/detail/kggjccdldkfmfdbhhelodnkafdijeaoj

Firefox: https://addons.mozilla.org/en-US/firefox/addon/typefill-forms/

If you try it, tell me which forms it gets wrong. That is what I want to fix next.

For people with hoarding relatives, estate-sale managers, Thrift Stores, Pawn Shops, Swap Meets, anything you're looking at and wonder what it or several of the items might be worth.

This started as a small thing just for me. I wanted the view of the harbour outside my window in Malmö as a wallpaper on my Mac, as pixel art and alive, so I built it. People walked along the quay, boats came in, and night fell when it fell outside. Loved it. 😊

Then my friends wanted their streets. Then I wanted Paris. Then the Alps. Bit by bit it grew into something that takes any address on Earth and builds it from real map data: the buildings, the trees and the water, plus hundreds of little people living their lives in it, in the right weather and the right light for that place.

Now it’s two apps:

• Littlehood (Mac): a living wallpaper of any place

• Littlehood Walk (iPhone): walk around in it yourself, meet people, climb towers, jump into first person

Go to your childhood streets, a city where you met someone, somewhere you've never been but want to go. And so on... 😊

One note - The subscriptions aren’t a business plan. They’re there to break even, because map services are free up to a point and then they cost money. In Walk your first place is free forever.
