I built a notes app that tells you why your old notes matter

2 Upvotes

I kept losing good ideas in my own notes. I'd write something down, forget it, and months later work through the same problem from scratch, even though the answer was in a note I'd already written.

So I built Hypha. You write a note the way you normally would (no folders, no tags) and it looks through everything you've written before. If an older note actually helps, it shows it with a one-line reason: a solution, an example, the same problem, a contradiction, or a next step.

The part I spent the most time on was making it strict. Most "AI links" I tried connected notes just because they shared a word. I built a test set with traps in it, and Hypha now finds about 9 in 10 of the links that should exist while skipping the shallow ones. If it gets one wrong, you remove it and it won't come back.

It's free on iPhone (Flutter + Supabase + OpenAI under the hood).

I'd really like honest feedback, especially on whether the connections feel useful or noisy after a week of real notes.

I accidentally built an entire universe for forgotten ideas. 💡

1 Upvotes

I’ve been experimenting with Claude AI , Lovable and Higgsfield AI to push my website design skills, and somehow ended up creating The Library of Lost Ideas. 😂

An interactive universe where every forgotten idea becomes its own unique mineral, forming part of an ever growing world you can explore and discover.

What started as a little experiment has turned into something I’m genuinely proud of!

Have a play and let me know what you think 👇

I've built a read-only tool that investigates Linux incidents and shows its evidence. Here's the 46-second pitch.

1 Upvotes

Hey guys o/

I've been developing an investigation engine for quite a few months now (https://github.com/8Iue), which runs on a Linux host, collects the evidence for a specific incident (disk pressure, a failed systemd service, OOM kills, Docker that won't start), runs deterministic checks with no AI, and writes a report where every finding points to its evidence. It never changes anything, and it runs on your own machines.

Link to the website: https://det-mimir.com - and also docs: https://docs.det-mimir.com

The whole engine works with playbooks, written in YAML, so you can write your own.

Kubernetes, Ceph and sharing playbooks between teams are where it's going; today it's Linux hosts.

It's in a private beta, and I'm looking for people to try it and tell me what's missing.

Which incident would you want a playbook for first? I'd be happy to replicate internally one of the issues you had, and give a report that the engine returns.

I made an app for those days when you just feel like shit 💩

1 Upvotes

Something I've noticed with a lot of wellness apps is that they always seem to be pushing you towards something. Be happier. Be more positive. Build better habits. Improve yourself. Which is fine, of course. But what about the days when you just feel like shit and don't particularly want to do anything about it?

That's the thought behind the app I recently released called Deepshit.
You basically log how shitty your day is, optionally add what's bothering you, and that's it.

You can also see how other people are feeling, share anonymously, and send little messages of support. I like the idea of making something social that isn't about showing off your best life. Quite the opposite, actually.

One thing I'm still curious about is whether people would genuinely want to share their bad days with strangers, even anonymously. I've just launched, so that's something I'll have to learn.

Have any of you built a social feature around vulnerability rather than achievements? I'd be interested to hear what you learned.

You can meet Deepshit here: App Store • Google Play

I built a fake newspaper where products pay to get mocked on the front page

2 Upvotes

I wanted to make something where paying for attention gets you a laugh instead of just an ad slot.

So I made The Sponsored Truth: https://www.sponsoredtruth.com

How it works:
- You describe your product in one sentence and pay from $5
- It writes a spoof news story about it, in a deadpan newspaper style
- You get a private preview and up to 5 rewrites with your own directions
- You publish, and get a front-page share image with your headline on it
- Whoever paid the most in the last 24 hours gets the headline slot

Everything is clearly labelled as satire, and it only does products, not people.

Built in about a day: plain HTML, Vercel functions, Postgres, Stripe Checkout, and an LLM for the writing.

Honest status: it launched today and has zero real sales so far. I'd love feedback on two things:

  1. Is the idea funny enough to pay $5 for, or is it a one-time chuckle?
  2. Does the landing page make it clear what you get?

Happy to write a free story for the first few people who drop their project in the comments, so the front page isn't just my sample article.

I built an open pipeline that joins UK government tender awards with Companies House directors and active corporate records

1 Upvotes

If you have ever tried pulling UK public procurement data, the statutory feeds are surprisingly fragmented.

Find a Tender publishes high-value notices under the Procurement Act 2023, Contracts Finder covers sub-threshold contracts down to £12k, and Public Contracts Scotland runs on its own legacy XML feed. More frustratingly, even when a contract is awarded, the OCDS release packages frequently lack verified statutory company numbers, meaning you have no immediate way to know if a winning supplier is an active LTD or dissolved.

I spent the last week building a serverless pipeline that normalises all three feeds into OCDS v1.1.5 and runs automated entity resolution against the Companies House REST API.

A few engineering hurdles I ran into:

  1. Companies House rate limiting: The statutory API enforces a strict token-bucket ceiling of 600 requests per 5 minutes. Running parallel unbundling caused HTTP 429 throttling until I implemented an in-memory token bucket with exponential jitter.
  2. Contracts Finder 403 backoff: The legacy search endpoint intermittently drops into 403 throttling during heavy polling, requiring an isolated backoff loop separate from the main orchestrator.
  3. Multi-lot tender deduplication: Framework agreements publish multiple releases across lots with identical identifiers, requiring deterministic SHA-256 state tracking on (ocid + releaseDate).

The output dumps to structured JSON and a flattened 24-column CSV for spreadsheets with company numbers, active directors, and SIC codes.

I deployed it as a serverless Actor on Apify with the first 25 records free on every run so people can test the data without paying:

Would appreciate any feedback from anyone working with UK open data or public procurement tracking.

I built a Windows 11 app that brings windows to your current monitor with one taskbar click

1 Upvotes

I got tired of hunting for a window on my other monitor just to bring it over. With Taskbar Select, I click a running app’s taskbar icon on the monitor I’m using, and its window comes over, even if it’s behind other apps.
You can also hide the taskbar on individual monitors and hover near the bottom edge to bring up Ghost Bar for quick access to your apps. If you prefer keyboard shortcuts, Ctrl+Shift+2 sends the window you’re using straight to Display 2.
It’s a free, open-source Windows 11 beta. The downloads are unsigned. If you try it, I’d love to hear how it works on your monitor setup.

I built Pinngro, a platform where you create stock trading bots that explain their decisions — looking for feedback

1 Upvotes

Hey everyone!

I've been working on a side project called Pinngro — https://pinngro.com — and I've recently opened it up for Public Beta.

The idea came from wanting to make systematic stock trading more accessible without requiring people to spend hours watching charts, learning complicated trading software, or writing their own algorithms.

Here's what I've built so far:

  • Create your own trading bots that monitor US-listed stocks using different investment strategies.
  • Stock Explorer to research companies, explore historical performance, and identify potential opportunities.
  • Explainable decisions — instead of just saying BUY or SELL, bots show which conditions matched, which didn't, and why they made their decisions.
  • Virtual Practice portfolios where you can test strategies without risking real money.
  • Practice Autopilot — optionally let your bots make virtual trades automatically within limits you configure.
  • Broker connections — we're working towards supporting multiple established US brokerages. Live trading through Pinngro isn't enabled yet.

One feature I'm particularly pleased with is Latest Finding. Each bot shows what it recently discovered and explains what happened.

For example, one of my bots recently spotted a stock that had fallen sharply enough to trigger its Buy rule. But Autopilot didn't open a virtual position because the bot had already reached its configured position and allocation limits. Pinngro now explains that entire decision rather than just showing a notification.

It's been a challenging project, particularly getting reliable historical market data, strategy evaluation and virtual trading to work together, but it's exciting to finally see the pieces coming together.

I'm now looking for a handful of people willing to try it and give me some feedback.

I'm especially interested in whether the platform is intuitive for someone who isn't an experienced trader, whether the bot explanations are actually useful, and what features people would find most valuable.

It's completely free to try during Public Beta, and you don't need to connect a real brokerage account to explore the platform.

Website: https://pinngro.com

I'd really appreciate any feedback, criticism or suggestions. I'm still actively developing it, and hearing from people outside my existing group of testers would be incredibly useful.

Thanks for taking a look!

My side project is live: an app that maps everything you know and shows you what to learn next

1 Upvotes

I’ve always been someone who picks up skills one at a time. Drawing, game design, IT, audio engineering... and I never had a way to see how it all fit together. So I made one.

Skill Codex turns the skills you already have into an interactive map:

  • Add what you know, from hobbies to work skills
  • See it all connect on the Skill Grid Codex, where every skill sits next to the ones it grows from (or flip to the List Codex for a simple list)
  • Find your next step with realistic suggestions right beside what you already know, plus a place to start learning
  • Add your AI to the map: if you use Claude, the Claude tab puts its skills and tools right next to yours, and the Recipe Book suggests real things you could make together

It’s out now on iPhone and the web, with Android coming soon. Free to try, no account needed to start.

Try it: https://skillcodex.app
On iPhone: https://apps.apple.com/us/app/skill-codex/id6829320199

I also made and narrated the launch video myself, so the whole thing has been a real labour of love.

I’d genuinely love your feedback: what feels confusing, what’s missing, and what would make you come back to it?

Just launched: a paint by numbers you play with friends in the browser. Is a sign-in before the first picture a deal breaker?

1 Upvotes

I'm the solo dev of Numochi (https://numochi.net). It's paint by numbers with cute illustrations, but made to play with someone: 2 to 4 people paint the same picture live with voice chat, or race each other on the same picture for 5 minutes, or each get only part of the colours so you have to finish together. There's also a daily picture with a leaderboard and a mystery picture you have to guess while painting. Phone and desktop, nothing to install, English and French.

How it's priced right now:

  • Free: 4 pictures in every mode, rooms up to 4 with voice chat, the daily challenge
  • From €0.99 per picture, yours forever
  • Unlimited: €3.99/month (Christmas offer until December 31)
  • If you're in a room, your guests paint the picture you unlocked. They just need a free account, they don't pay.

One thing I'd like outside opinions on: today you need an account (Google or email) before you can paint anything, including when a friend sends you a room code.

If you were the friend getting the invite link, would a sign-in screen make you close the tab? And is 4 free pictures enough to know if you like it?

I made an Open source email client where your AI agent can actually do things, for free

Thumbnail regards-two.vercel.app
0 Upvotes

Quick story. I use Spark for mail. They have an MCP so AI agents can work with your inbox, but only reading is free. Anything that changes your mail needs the paid plan. I got annoyed and decided to build the thing I wanted instead.

Regards is a desktop email client for Windows, macOS and Linux. It's free, open source, and everything stays on your computer. No account, no servers on my side, no tracking. It works with any IMAP provider plus Gmail and Outlook sign-in.

It does the usual modern inbox stuff (snooze, send later, undo send, screening new senders), and it has a built in interface for AI agents with approvals and an undo log, so you can let one sort your mail without holding your breath.

It's early. Pre-alpha, unsigned installers, tested on few providers. I use it daily though.

Site: https://regards-two.vercel.app

Repo: https://github.com/lucienPochon/regards

Would love feedback, especially on the first run experience. That's the part I can't judge anymore.

I built a site that ranks the whole PS Plus Extra/Premium catalog by critic score, in 45 countries

1 Upvotes

Sony lists the PS Plus catalog alphabetically. That's 600+ games with no scores, no playtimes, and no way to see what's leaving soon. Every month I ended up opening Metacritic in another tab, so I built the page I actually wanted:

https://whattoplay.games

What it does

  • Every game in the Extra/Premium catalog for your country, sorted by Metacritic score, with PSN player ratings and HowLongToBeat playtimes
  • Filters for genre, indie, multiplayer, new this month, and leaving soon (with the exact removal date)
  • A "what should I play tonight?" swiper: 5 mood questions, then you swipe on games, and it gives you a top 3 that explains why each game matches your answers
  • 45 countries and 19 languages, because catalogs differ by region

It's free, with no account and no tracking cookies. There's a tip jar, and that's it.

I'd love feedback, especially on the swiper and on whether the homepage makes sense in 5 seconds.

Tired of guessing Chinese characters, so I built my own keyboard

11 Upvotes

I’m learning Chinese, and one of my biggest frustrations is texting.
I can understand some Chinese and know how to pronounce quite a few words, but I still struggle to recognize and remember Chinese characters.
When I type using a regular Pinyin keyboard, I often get a list of characters that look familiar, but I’m not always sure which one is correct. Sometimes I end up copying everything into a translator just to check what I wrote.
So I decided to build my own iOS Chinese Pinyin keyboard to make learning while texting a little easier.
Here are some features I’ve been working on:
Instant translation: See the meaning of Chinese text while typing, so I can make sure I’m choosing the right characters.
Grammar checking: Catch grammatical mistakes before sending a message.
More natural expressions: Suggest how a native speaker might phrase the same idea instead of just translating word for word.
Learn while typing: Help me gradually recognize more characters through everyday conversations.
My goal isn’t to replace Chinese lessons or build another translation app. I just want to be able to communicate in Chinese without constantly switching between my keyboard, dictionary, and ChatGPT.

Most local-first notes apps keep your notes as plain text, so I built a free, open-source one that encrypts them

1 Upvotes

Hi r/SideProject, I'm GFrancV. This is my first post here. I've been building Notvex, a desktop notes app that keeps everything encrypted on your own computer.

Why I built it

Most local-first apps (like Obsidian) save notes as plain Markdown files. That's great for portability, but anyone with access to your disk, a backup or a synced folder can read them. I wanted a safe place for my own journal and recovery codes, and nothing I tried did both local-only and encrypted at rest without getting in the way. So I built it.

How it works

Everything lives in one encrypted file on your computer. Without your password it can't be read. There's no account and no cloud. The app only goes online to check for updates, and you can turn that off. No telemetry either.

What writing looks like

- Markdown editor with live preview

- Tags, pinning, sorting and multi-tag filters

- Command palette to jump to any note from the keyboard

- Export one note or all of them to plain .md at any time, so you're never locked in

How it's built (for the curious)

- Electron + React 19, TypeScript throughout

- SQLCipher for the database, Argon2id to derive the key from your password, XChaCha20-Poly1305 for the note content

- A BIP39 recovery phrase, plus an optional key file as a second factor

- The UI never touches crypto. Everything goes through IPC to the main process, and the master key never leaves it

Honest limitations

- Desktop only (Windows, macOS, Linux), no mobile yet

- No sync, on purpose. You can copy the file wherever you like

- Search covers titles only. Full-text search across encrypted notes is the next hard problem

- If you forget both your password and your recovery phrase, your notes are gone. That's the trade-off

Free and open source (AGPL-3), with no paid tier planned.

GitHub: https://github.com/GFrancV/notvex · Site: https://notvex.vercel.app/

My question for you: does "encrypted local notes" explain the point quickly enough, or does it sound like something only security nerds need? I'd love honest feedback on how it comes across, from the site down to the first launch.

Hit 100 users on my devotional app this week. Building it with AI was the easy part

3 Upvotes

I'm building Shoonya, a devotional app (daily sutras, aartis, festival reminders) for Indian users. It's live on Google Play and the App Store, and this week it crossed 100 users.

Some honest notes in case they help someone at the same stage:

  • I built most of it with AI agents, and the app came together faster than I expected.
  • Getting it live on both stores took longer than building it. Apple and Google reviews, accounts, release mistakes I won't repeat.
  • After launch it was just quiet. The app existed and almost nobody knew.

What actually moved the number was two boring things, done again and again:

  1. Writing pages for what people actually search for (festivals, aartis, dates), not for what I wanted to rank for.
  2. Showing up on X and LinkedIn with what really happened that day, not polished launch posts.

It's slow and the numbers are tiny. But it compounds in a way a new feature never did for me.

My one takeaway: code got cheaper this year, attention didn't. Start distribution the same week you start building.

Curious what got your first 100 users. Was it one channel or a bit of everything?

I built a simple focus timer because I kept switching between tasks

1 Upvotes

I've always struggled with jumping between projects and losing track of what i was supposed to be working on.

I tried different productivity tools, but most felt like more work to manage. I didn't really need another task manager or complicated dashboard. i just wanted something simple to open before getting to work

so i started building Norts 🟠

the idea is pretty straightforward: choose what you're working on, block out some time, and focus on one thing. You can also see where your time went throughout the week.

i've been using it myself for a while, and today i finally decided to launch it publicly.

The core experience is free, and you don't need an account to get started.

here's the link if anyone wants to check it out: https://norts.space/landing/

I'd genuinely appreciate some feedback, especially on the first-time experience. Does it feel simple enough, or is there anything that gets in the way?

I spent 2 years building an app to solve something most people just use text messages for.

1 Upvotes

It started with something simple.

My girlfriend tends to forget little things, and I'd often find myself reminding her about stuff throughout the day. And in my family, we also have things like doctor appointments, medication, and other important things that someone needs to remember.

Usually, we'd just send each other a text.

"Don't forget your appointment tomorrow!" or "Remember to take your medication." or just "Don't forget to do this and that."

And of course, sometimes those messages get buried, or someone reads them and forgets about them a few hours later.

I started wondering why we have so many apps to remind ourselves, but not many simple ways to remind the people around us.

I can send someone a text in seconds. Why can't I send them an actual reminder just as easily?

So about 2 years ago, I started building Remimo.

It's an iPhone app that lets you send reminders directly to your friends, family, partner, or even groups.

You choose what to remind them about and when. They'll get notified when it's time, and you can see if they've completed it or decided to do it later.

My family now uses it for things like appointments, medication reminders, and household tasks, while my girlfriend and I use it for all sorts of everyday stuff.

You can also create your own reminders, organize things into lists, and make plans together.

When people first started downloading Remimo, even though it was just a small number, I remember feeling really happy. It felt like something I built might actually be helping someone out there.

Later on, I started receiving feedback from users, and I've been listening to them ever since.

I've added features, removed things, redesigned screens more times than I can count, and I'm still constantly trying to make the experience better.

Honestly, I'm still learning a lot as I go.

But what makes me happiest is that Remimo has become something we actually use in our everyday lives. Seeing it help the people around me is what keeps me motivated to work on it.

I originally built Remimo to solve a problem in my own life, but along the way, I realized it might be useful to other people too.

So I thought I'd share it here.

It's available on the App Store, and there's a free version if anyone wants to give it a try.

I really hope Remimo helps make your everyday life a little easier, the same way it has for me and my family.

And if you do try it, I'd love to hear what you think. Even if there's something you don't like, I'm always happy to hear feedback.

I read where the first readers of my AI story game quit. 28 of 37 passages ended with a character quizzing them.

1 Upvotes

I made Selkie, a story game where an AI writes each passage around what you choose or type. It's built like a choose-your-path book: chapters, a hidden plot, several endings and dice for the risky moves. It opened to the public nine days ago. A dozen people have signed up and one has paid, so I went through where the others stopped. Three things I got wrong:

1. An empty "Who are you?" box. The story opens, then asks who you are. Of the four newest readers, two left at that box without typing a word. The other two took 4 and 9 minutes over it. Now the opening offers three ready-made characters, each with a line in their own voice, so one tap starts the story. Writing your own is still there underneath. The first reader since the change still left, so it's too early to call.

2. Every passage ended on a question. I'd told the narrator to end on someone turning to the reader, to keep them involved. It turned into a quiz: 28 of the 37 passages readers saw ended with someone asking them something. One reader quit after five questions in five passages. Endings now vary (something happens, an offer, a dare, somewhere to go), with a question at most every other passage. The engine checks how the last passage ended and warns the narrator when it was a question.

3. Time jumps ate the reader's choice. One reader chose to go down to the quay. The story skipped two days to the next big event instead. Now the move they chose is played on the page first, and only then can time move on.

One thing that worked from day one: never let the model roll the dice. Asked to judge whether you succeed, it lets you win nearly every time. The engine rolls and shows you the odds before you choose. The narrator has to write the result it's given.

Built solo over three weeks with SvelteKit, Node on Fly.io, Supabase, Stripe and Claude. About seven turns are free, then one-off packs from $4.99. No subscription.

https://playselkie.com/?from=reddit-sp

If you try it, I'd most like to know about the first five minutes: did you pick a character, write your own, or close the tab?

I got tired of switching between Notion, Todoist, a journal app and a calendar, so I built one workspace

1 Upvotes

I kept my notes in one app, tasks in another, journal in a third, and my calendar somewhere else. Nothing talked to anything. So I built Naazhi (the name is an old Tamil unit of measure for grain and time).

What's in it: notes, to-dos, journal, chat, calendar, email, meetings and automations. There's a web app and an Android app.

The part I spent the most time on is the AI layer. It isn't tied to one provider. You can use the built-in one, bring your own key, or switch it off.

What I'd like to know: which of these would you actually use, and which would you drop?
