I wrote this Telegram bot that translates any video with AI-generated subtitles in about 2 minutes. You paste a YouTube, TikTok, or Instagram link, pick your language, and get back the video with burned-in subtitles.

It started because my wife watches Chinese dramas and new episodes never have subtitles for our language. Turns out thousands of people have the same problem — Arabic speakers watching anime, Russian speakers following Turkish series, Persian speakers catching up on K-dramas.

Supports 40+ languages, works with any video link or direct file upload. There's also a Mini App inside Telegram for a more visual experience.

Hey this looks cool but wanted to highlight a bug. I opened the bot, tapped on sample video and I got the “translating a sample Turkish drama…” message twice. Then it said “your first translation is ready” so I press view in the app and the recent list shows the duplication. It says the first one is ready but the second was in progress. I close the app and see a “our whale friend is gathering video” with a progress bar. So I guess it’s not ready? Then I get a failure message which looks like the second video failed? Anyway, cool idea but it seems buggy and I think the app UX could be simplified, good luck!

Thanks for your report, I will try to fix it asap :D Please open the mini app inside the bot, it has much better UI.

This looks cool, but what I'd really like is a self-hosted version that I could use to auto-subtitle videos I already have locally. This would help my language learning a great deal.

If any of you have already figured out a tool/workflow for this, I'd love to learn from your experience.

This thread prompted me to look into this. It seems that all I need is a thin wrapper around whisper-ctranslate2. So I wrote one and am playing with it right now.

I'm finding language auto-detection to be a bit wonky (for example, it repeatedly identified Ladykracher audio as English instead of German). I ended up having to force a language instead. The only show in my library where this approach doesn't work is Parlement[1], but I can live with that.

On the whole this is looking quite promising. Thanks for the idea.

I am working on https://baolib.org.

Applications on the public cloud raise strong concerns about data protection. As an architect, I spend a meaningful part of my time ensuring the security of customers’ data in the cloud.

Bao introduces an innovative approach where data remains on local devices while the cloud provides encrypted storage for synchronization and peer exchange. Because cloud providers cannot access the data, the need for due diligence is reduced.

Any feedback is welcome.

Any connection with bao or openbao, the fork of hashicorp vault ? I fail to see any reference on the site

Notello - local-first notes & tasks app for individuals / small teams.

We got tired of bouncing between a note-taking app and a task tracker. Notion combines them but it's slow and its offline capabilities are limited. Linear is fast but tasks-only. Obsidian is local-first and e2ee but single-player. So we're building Notello - notes and tasks in one deeply nestable tree, real-time multiplayer, works offline, e2e encrypted.

Reads/writes hit local SQLite first, sync happens in the background. That way everything is instant, you don't notice the network except in some very special use cases. Runs on web and desktop with shared core logic.

We're building it for powerusers like us who want IDE-like navigation, block editor, control over their data, granular sharing down to individual entries and more. Your work workspace and personal workspace live side by side, no switching workplaces.

Old website that needs refreshing (we failed to build it beyond an MVP a decade ago but armed with more experience, we're giving it our best this time): https://notello.com . Launching within the next few months!

I started working on an "anti-habituation" motivational reminder app:

(Note: Only the macOS version is tested extensively at the moment)

I've been working on a Ontario open data MCP: https://github.com/sprine/ontario-data-mcp

There is a wealth of data that's behind CSVs and other data formats. This uses DuckDB as a common (local) database to cache and run queries against, and enables going across datasets for insights using LLMs.

The "OpenCooler" A silent, drop-in water cooling unit for labs, temp controlled mattress covers, pet coolers, whatever. The current market stuff is too expensive and it looked like a good learning project <https://hackaday.io/project/205182-opencooler>

Two choropleth map projects I've wanted to make for a while:

https://housepricedashboard.co.uk - shows a visualisation of house prices in England and Wales since the 90s, with filters for house types, real vs nominal, and change views over time

https://councilatlas.co.uk - similar structure to the above, but focusing on local council datasets. The idea is to make it easier to compare your local council's performance against the rest of the country.

I'm building a personal habit tracker, solely for my own use. It is intended to be pretty basic - just a html file, with data saved by vanilla JS in browser's local storage. Currently about 50% of the work is done by AI (Cursor).

After adding a couple of extra features and having a "finished" tracker, I will try re-implementing this tracker in React, Svelte, Vue, Preact and some others.

My goal for this project is twofold: to get familiar with these frameworks and to practice using AI as a personal tutor (leading my way and answering my questions).

I've tried learning React, Laravel, etc before, but I've used them to build a fresh project from scratch and I've always got stuck early on due to the lack of knowledge/understanding.

I hope that re-implementing something that I already know and understand fairly well would make my learning process much more effective.

Hoopi Pedal: A 2-channel digital effects + recording pedal, based on the Daisy Seed and the ESP32 [1]. PCB design, embedded firmware, DSP and Flutter app - all are mine. Some technical notes on firmware (OTA updates, etc.) and Flutter app dev (using native methods for vidoe-audio sync, auto cross-correlation, etc.) are published on my blog [2].

Ordr — AI task manager for people with too much to do and too much in their head: https://useordr.app

Most productivity apps make you do the organizing — projects, tags, priorities, fields. That's fine when you're calm. It's impossible when you're overwhelmed.

I'm building for the moment when your brain is full and you just need to dump everything out. You throw in voice, text, images, links — Ordr calls an LLM to parse intent, extract tasks vs. events, assign order, and surface one clear next action. No tagging, no sorting, no deciding. Just: here's what to do next.

Built with Flutter + Supabase + Groq/Cerebras. Still early.

Curious if anyone here has hit this wall — tried every app, built their own system, still feels broken. What did you actually need that nothing gave you?
