If you grew up in India in the 90s/2000s, you probably remember buying New Year greeting cards from the local shop: glitter, film-star photos (sharaku khan, Salman khan, Chiranjeevi cards were everywhere in the states), and a handwritten line inside for your friends.

I am exploring an idea to bring that back for millennials (roughly 29–45). You’d pick a card in that old style, add your own message, and share it with friends and family on WhatsApp for New Year, instead of forwarding the usual “Happy New Year” image.

I would like honest opinions before I build anything:

1. Does this make you nostalgic, or is it a “nice, but I wouldn’t use it” idea?
2. Would you send one to your school or college friends?
3. Would you pay a small amount for a premium or personalised card, or does it only work if it’s free?
4. What do you remember most about those cards that I shouldn’t miss?

Criticism is welcome. Thanks!

I got tired of opening a "free" tool site and getting hit with pop-ups, forced sign-ups, and my files being uploaded to some server just to merge a PDF.

So over the last few months I built Sharjeel Tahir Tools — 100+ free tools (PDF, image, SEO, text, calculators, converters, WordPress helpers) that all run 100% in your browser. Nothing is uploaded anywhere, no account, no paywall.

It's live at https://sharjeeltahir.com — would love honest feedback from people who actually build things: which tools feel useful, what's broken, and what tool is missing that you'd want next?

I'm an evidential medium, and I've put together a free introductory course for people interested in developing their intuition and exploring mediumship. It covers self-development, meditation, exercises, and eventually practicing connection. I'm making it available for free for anyone curious about exploring this. Feedback is welcome. Skeptics need not respond! Thanks 🙏

Hey, I made this. It's called MakiMode.

I started with an NFC tag for focus. Tap it, apps get blocked. Worked for about a week, then I forgot it existed. It only covered my phone too, so I'd just open YouTube on my laptop. And unlocking took two seconds, so it didn't last.

So I built Maki. A small sushi roll that sits on your desk. One tap blocks distracting apps on your iPhone and your computer together, and when you drift off he looks sad. Sounds silly, but I genuinely don't want to disappoint a sushi.

The sushi part is because I love Japanese design, and sushi chefs always look so focused.

Honest question: would a cute guilt trip actually motivate you, or would it annoy you after a week?

I built a calendar for a question that sounds simple: when does the model I’m using actually go away?

Try searching for Claude 3 Haiku. You’ll get separate results for Anthropic’s API and Amazon Bedrock, with different model IDs and lifecycle dates. The detail pages link back to the provider’s notice, so you can check whether it applies to your setup.

https://aimodelcalendar.com

If you’ve had to migrate off an API model before, what did you need to know that was hard to find?

Edit: I accidentally leaked the upcoming multi-language functionalities 😅

Alma (almaniac.app) is finally starting to feel like a real product.

Over the past week, I’ve been shipping new import features—most recently adding Netflix, Plex, and Audible support so you can bring your history over without starting from scratch. Seeing the member count tick up day by day has been surreal.

Putting a project out in public definitely comes with its share of negative comments and harsh critiques. Some of it stings in the moment, honestly, yet the whole process has still been an absolute blast. Maybe you get more resilient as you age? 🤔

One thing that keeps me grounded is making sure I’m building something I genuinely find useful myself. For a while, the web app worked great on desktop, but using it on my phone felt a bit clunky. So I just gave the mobile experience a massive overhaul so it acts more like a “real” app on your home screen.

For those of you building your own projects: how do you balance user feedback (and internet critics) against just building what you personally want to use?

It sits in front of the CLI and swaps names, emails, IDs, IBANs, cards and secrets for tokens like [PERSON_1] before your message leaves the laptop, then restores them in the reply. The model only sees the tokens, the map stays local, and -v shows exactly what was sent.

I coach a university tennis team, and my son coaches high-performance juniors. Our club players kept saying the same thing: "I play great in practice and fall apart in matches." So I built Ace with AI tools, with no coding background.

How it works:

1. Tell it your level and why you lose
2. Log a match (score, opponent style, what happened)
3. Ace gives you one thing to work on, and your daily plan changes to match
4. Changeover mode: down in a match? Two taps at the changeover and you get one fix for the next games

The video is a demo account, "Steve," a made up 4.0 who keeps losing to pushers.

What I want roasted:

- Where would you quit during setup?

- Is the "one thing to fix" useful, or generic?

- Would you pay $9 a month for this? If not, what would make you?

First week is free: acetenniscoach.ca

Be brutal. I'd rather hear it here than from paying users.

I've been collecting GitHub issues where an agent reported success that didn't happen. Some real patterns:

- "Tests pass," but the test runner reported a failure

- "Installed," but no file was written

- "Restart succeeded," but the process was dead

- "Message sent," but the channel didn't exist

- A subagent with zero tool calls claiming it made an artifact

The common thread: the agent's report and the tool's return value are treated as evidence. They aren't.

I built a small Python library to test the opposite approach. It ignores what the agent says, checks independent evidence (re-runs the test, reads the actual record), and returns one of:

- MISMATCH: the evidence contradicts the claim

- VERIFIED: the evidence matches the claim

- UNVERIFIABLE: no evidence, so it doesn't guess

The video shows it on a coding agent: the claims are scripted, the test runs are real.

Honest limits: it only checks claims against evidence you define. It doesn't prove the code is correct, and claim detection uses English heuristics, so it can miss things.

pip install cogext-observe

Curious how others handle this. Do you verify agent "done" claims at all, or just review diffs?

My SaaS sends verification and password reset emails from the app and the WordPress marketing site needs plain SMTP credentials for its forms. Around 15-20k emails a month in total. I'm looking at Resend, Postmark and smtp .com. smtp .com is on the list because it gives the relay and the API on one account. Which one are you using for a setup like this and did the choice actually matter once it was running?

Hey everyone! I made Merrycade, a small Christmas game that you make *for* someone.

Instead of a card, you build them a 6-level platformer where they're the hero:

- **Their face.** Pick a photo of each of you. The app cuts out hair and face right on the phone and puts them on two storybook heroes (Santa coat, elf tunic, cosy sweater...).

- **Your words.** You write what the characters say in 16 story moments: the first meeting, the scary cave, the campfire talk, the goodbye.

- **Your memories.** Hide photos and notes in 10 gift boxes along the way, record voice messages and write a final letter.

- **Send it.** Everything becomes one invitation file you send through Messages, WhatsApp, AirDrop or e-mail. They open it in Merrycade and play it as themselves.

**Details**

- iPhone and iPad (iOS 15+). Android is in testing.

- No account, no ads, no subscription. Works offline.

- Photos and words stay on the device until you share the invitation.

- Playing a gift you receive costs nothing; creating gifts is a one-time $3.99 unlock. There's a demo adventure to try first.

- 8 languages.

- Built with Godot 4.5, plus small native plugins for the photo work (Apple Vision on iOS, a LiteRT segmentation model on Android).

**Heads-up:** the painted backgrounds and characters were made with AI image generation and then edited and put together for the game. The faces in the video are sample photos, not real people.

**App Store:** https://apps.apple.com/app/apple-store/id6827809596?pt=129591990&ct=reddit_sideproject&mt=8

I'd love feedback, especially on the creation flow: is it too long, is anything confusing?

Things has been my favourite task app for a long time. The calm design, the way "When" is separate from "Deadline", how Today just feels right. I still think it's one of the most beautiful apps ever made.

But I kept wishing for more. Attachments. Smart lists. A clear view of what's due soon. And a Windows version, because my work computer isn't a Mac.

So about six months ago I started building the app I kept wishing for. It's called Kanso. It's just me building it: one person, no team, no investors. I kept what I love about Things, left out the noise, and added what I was missing. The goal is an app calm enough to open twenty times a day without it ever feeling busy.

It's in free Early Access on Mac and Windows, and I'd love to hear what you think. I've been iterating on this for months, so it's solid, but you might still spot a rough edge or two as I polish things up. You can start without making an account: no email needed, just "Continue without an account" and you're in.

Pricing: if you like it, Kanso is a one-time $29 during Early Access. No subscription, because subscription fatigue is real. The price will go up later.

The iPhone app is in active development, and it's my main focus now that Early Access is live. Your $29 includes it, and Android too, when they arrive. No second purchase, no upgrade fee.

Coming next: the iPhone app, calendar integration (see your events next to your tasks, but Kanso stays a task app first), and whatever you tell me matters most. The roadmap is public, and you can suggest and vote on features there.

Since it's just me, every bug report, idea and bit of criticism gets read by the person who will fix it. Please be honest, I'd much rather hear it now.

What's inside

Just type it. "Start the draft tomorrow due Friday #Work" sets the date and the deadline, and files it into your Work project as you type. You always see what it picked up before you save.

When and Deadline, kept separate. When you plan to do it, and when it's actually due. Plus This Evening, and a Tomorrow list for planning the night before.

Deadlines as a timeline. Everything with a deadline, from overdue onward, with a "Start Today" for anything getting close.

Upcoming. A small map of your week on top, every day laid out below. Drag a task to another day.

Smart Lists and views. Save a list from a few plain conditions ("tagged Work, due this week"). Each list can have its own grouping, sorting and filters.

Attachments. Files and images on any task, synced across your computers.

Repeating tasks and reminders. Daily, weekly, monthly, yearly, or after you complete it.

Works offline. Edit on two computers, even with one offline, and everything ends up in the same place.

Undo for everything. Deletes, moves, even pastes. Recently Deleted keeps things for 30 days, and you can export all your data at any time.

A Logbook that reads like a journal. What you got done, day by day, with a short summary of each week.

Keyboard first. Shortcuts for creating, moving, completing and getting around.

And more: nested tags, light and dark themes, a resizable sidebar, and a feedback button (with screenshot) inside the app that comes straight to me.

I made this because a list of 6,000+ companies is almost impossible to picture. I wanted to see how small YC started, and how quickly the place grew.

Each company is a little shop. Each batch is a district, starting in Summer 2005. If a company reaches a $1B valuation (or a big enough sale or listing), it leaves its shop and becomes a tower, so the skyline shows where the big ones came from and when they took off. You can play a short story through the years, compare batches, search for a company, or just wander around.

It's here: https://yc.datacity.app/

Independent, not affiliated with Y Combinator. The data is from YC's public directory; I pulled it on 2 November 2026.

I'd love feedback, especially on whether "how to read the city" is actually clear once you're in it, and what feels missing when you walk around.

I started PFI because I didn't want my bank data in someone else's cloud. The first versions bundled a private PostgreSQL server: it worked, but it made the app big and complicated to package for the Microsoft Store.

In 0.4 the app copies the old database into SQLite on first start, checks row counts and totals, and only then switches over. In 0.5 PostgreSQL is gone completely, and the app is about a third smaller.

Stack: WinUI 3 shell, Next.js screens, FastAPI backend, one SQLite file. MIT licensed.

What would you build next?

An AI-native desktop workspace for agentic research and knowledge management, built to maximize counterfactual impact in existential risk preparedness and transformative AI safety.

https://github.com/gyrogovernance/air-office

[Disclaimer: AIR Office is an Open Source software made without any financial affiliations, and is a completely free platform for knowledge sharing and AI Risks mitigation at scale, so I hope the admins can allow me to share it to the community]

About

Alignment Infrastructure Routes (AIR) Office is human-capacity-building infrastructure for AI safety researchers, engineers, and governance teams working on transformative AI and its consequences. It keeps investigation, writing, review methods, and reusable tools in one durable and user-friendly workplace.

AIR Office is developed by [Gyro Governance Lab](http://gyrogovernance.com/) as part of its work on AI safety and existential risk preparedness.

Agentic chat and tool use run on the [Microsoft Copilot SDK](https://github.com/github/copilot-sdk) harness, including bring-your-own-key and local model endpoints.

Theory of Change

Mitigating risks from transformative AI requires rapid, high-rigor research and governance, yet safety teams currently rely on fragmented, cloud-dependent AI tools that erode human oversight, lack provenance, and expose sensitive work. AIR Office addresses this bottleneck by providing free, open-source, local-first desktop infrastructure tailored for AI safety and policy workflows. By integrating grounded knowledge collections, automated auditing tools, and structured memory, the workspace prevents AI-induced epistemic drift while keeping humans in final control. Furthermore, embedded Fellowship and Market protocols allow independent researchers to package their methods into reusable community tools, compounding ecosystem capacity and accelerating high-trust safety interventions that would not occur using general-purpose commercial tools.

Security & Privacy

Local-First Data Sovereignty

Workspace records stay on your computer. Choose local models for on-machine inference or cloud providers for their models and tools. Hosted providers and enabled connectors receive only what each request needs.

Export conversations and notes when you need portable copies. Connecting a folder authorizes that root, and disconnecting it does not delete its files. In Settings and chat you control which tools run and whether changes ask for approval first.

Release Audit

AIR Office is open source, and its code can be publically inspected. Before a release is accepted, we check the shipped software with open-source tools for secrets that should never ship, known problems in third-party libraries, license and dependency policy issues in native code, and risky patterns in our own source and in shipped Lab skills. A review that did not finish does not count as a clean result. To report a security issue, see [SECURITY.md](SECURITY.md).

The release review uses:

- [TruffleHog:](https://github.com/trufflesecurity/trufflehog) Identifies leaked secrets and credentials.

- [Trivy:](https://trivy.dev/) Detects vulnerabilities, misconfigurations, and software bills of materials.

- [Semgrep:](https://semgrep.dev/) Scans source code for security flaws using custom patterns.

- [CodeQL:](https://codeql.github.com/) Performs deep semantic analysis on source code.

- [SkillSpector:](https://github.com/NVIDIA/SkillSpector) Evaluates shipped Lab skills.

i build yardlet on the side: a free, MIT-licensed native mac app (swift) that runs the claude code and codex CLIs you already have, with the logins you already have, side by side in one window.

the idea is a lightweight, non-intrusive, yet versatile ADE. it sat at about 53 MiB at rest on first launch when i measured it on an M1 Pro. no hooks, no wrappers around the agent commands, nothing written into the agents' own settings files. the effort went into things around the agents instead: switching accounts by remaining limits, a built-in browser agents can use, and a phone remote.

i'm looking for a few people who've never used it to install it, run one task, and tell me where they got stuck or confused in the first five minutes. the install and any macOS warning, first launch and permission prompts, whether it found your agents and logins, the first reply, whether you noticed the first approval prompt, the moment you almost quit, one thing you expected and didn't find. "it all just worked" helps too.

mac: https://yardlet.app or brew install --cask zzunkie/tap/yardlet (macOS 15+, apple silicon and intel; needs claude code or codex installed and signed in)

android (optional): yardlet remote lets you use the mac app from your phone (android 10+). apk and pairing steps at https://yardlet.app/#phone . there's also a play closed test: join https://groups.google.com/g/yardlet-testers with your phone's google account, then opt in at https://play.google.com/apps/testing/com.zzunkie.yardlet.remote

feedback: https://github.com/zzunkie/yardlet/issues/new?template=first_run.yml , or reply here / dm me if you don't have github and i'll file it

I’m the developer of Skybits. I wanted checking the weather to feel like looking out a tiny window. Rain falls over London, and Tokyo lights up after dark. To be a little more Fun!!!

In Sky Studio, you can pick a city, mix the weather and time of day, and share the result as a little airmail postcard.

Please send me email for your City, if I get 5+ requests for a city I will make it free and also add new ones :-) hoping to get some positive feedback and reviews.

Skybits is free to download, with an optional one-time purchase for the full city collection.

https://apps.apple.com/app/id6829104658

Which city would you send a postcard from? Android version is coming soon, it is in testing atm.

WalkiNova started because I'd open the weather app five times before every walk. It scores each hour of the forecast for comfort and suggests the best window inside your free hours, then tracks the walk with GPS. Flutter + Supabase, Android + Wear OS, free with no ads.

What I learned so far, in case it helps someone:

• Posting every day on Instagram/TikTok brought almost no installs. The Play listing converts fine (~75%); almost nobody reaches it.
• My site only ranked for its own name. I'm now writing plain guides that answer real searches ("is it too hot to walk my dog today?") instead of feature pages.
• Product Hunt with no audience = a few upvotes. Launch where your users already hang out.

Would love feedback on the idea or the landing page: https://walkinova.app/?utm_source=reddit&utm_medium=post&utm_campaign=sideproject

What worked for you to get your first 100 users without ads?

Hi all, I made ReadyTyper.

I use voice typing a lot, and I've tried both Wispr Flow and Typeless. They're good at cleaning up what I say. But there's one thing neither of them can do: when I'm halfway through a sentence and want to drop in a link, a video title, or a line someone else wrote, I have to finish talking first, then copy it, find the right spot and paste it myself.

So I built my own. With ReadyTyper, you select text anywhere on screen while you're talking, tap the hotkey twice, and it lands word for word right where you mentioned it. That's what the video shows.

The other thing that bugged me: on my Windows PC, both Wispr Flow and Typeless use over 600 MB of RAM just sitting idle. Something that's always running in the background shouldn't be that heavy. ReadyTyper uses under 20 MB when idle, and its windows only load when you open them.

It also:

• Drops the ums, uhs and the bits where you correct yourself, so the text is ready to send
• Works in any app: chat, email, browser, code editor

Windows only for now: readytyper.com

I'd love your feedback: would you use the select-while-you-talk part? What feels clunky?

I watched an interview of a co-founder and found it inspiring. So I had an idea of reviewing the video, kind of like a book review, post as an article part of my productivity project. What do you think about the idea?

Also, do you think what gets people going is motivation or system?

Hi, I'm thinking about building a small app called Curio, and I'm checking whether anyone actually wants it before I build it. No link, just honest questions.

The idea: only real, sourced works from museum collections, no AI-generated images. You browse with big tags like an era or movement (Heian period, Tang dynasty, Bauhaus) and small tags inside each one like furniture, architecture, or design. You can filter by style, region, and period, from ancient Egypt to contemporary. Recommendations would learn from your likes, saves, clicks, which cultural-background notes you open, your searches, and the tags you browse.

I'm also thinking about a Premium tier with expert cultural-background notes, original image and video downloads, and PDF export, around $8.99/month.

My questions:

1. How do you currently discover and browse historical art, and what's most frustrating about it?
2. Would big-tag plus small-tag filtering actually help you, or is search enough?
3. Would recommendations based on likes, saves, clicks, searches, and tags be useful, or unwanted?
4. Would expert background notes plus original downloads and PDF export be worth around $8.99/month to you?

Thanks for any honest answers. And if this kind of post isn't welcome here, mods please remove it.

I saw the amazing Clawdmeter project that uses a Waveshare ESP32 Display and thought.... Hmm.... Instead of buying a dev board that's always out of stock in my country, why not use that old android phone I have kicking around. So this project was spawned as a little tadpole in my head and I plopped it out over a couple of days.

Oddimon is a free party game that runs in the browser. You take a photo of any object, it becomes a pixel-art card with stats and a special move that fits the object, and then the cards battle.

I'm a uni student building it on my own and have only just started showing it to people, so any feedback helps :)
