Ask HN: What Are You Working On? (Nov 2025)
Think n8n, but you bring your own code and optionally even your hardware to execute pipelines.
Free on iOS + iPad + macOS (Catalyst), and I'm working on adding additional skins, premium features, and Android soon! :)
The game has a farily simple frontend, but there is a fairly complex constraint solving algorithm as part of the puzzle making process. What makes the puzzle quite unique is that you can't "guess". You can only make guesses that are provable by logic. The algorithm ensuring this has worked flawlessly for months now (though I've manually inserted some silly mistakes once or twice).
Today's puzzle is one of the hardest to date. The difficulty resets on Mondays, and then gets harder again towards Sunday.
It's an instant remote control built for shared spaces. Anyone can use the remote with a QR code on their mobile device. Since its IoT there are lots of interesting features including permissions, various remote interfaces, universal remote capabilities and more.
These cards are super versatile prompts mediums and haven't been fully creatively explored.
Cheating in exams has quietly become a global industry — from small university tests to national certifications and professional licensing.
We’re building https://trustexam.ai that protect the integrity of high-stakes exams and certifications — from universities to government licensing and professional testing.
Our focus now is on scaling this globally and using ethical “white-hat” research to understand how people cheat and how technology can rebuild trust in digital assessments. What’s the best way to make that impact worldwide?
There’s so much nuance in HN threads that often gets missed elsewhere, so I decided to put start this newsletter.
Initially started as an experiment for 10 issues to see ig it gets traction, 6 issues in it’s at 68 subs and probably will continue for unlimited time period.

It lets you turn any article, YouTube video, or PDF into summaries, mindmaps, podcasts, chat conversations or infographics that match how you learn with just one click.
We just launched this week the Chrome extension so you can do all this in one click on any page, no login needed (with generous freemium usage).

Would love feedback from fellow builders.
