What happens if you combine a full Dungeons & Dragons rules engine with an LLM to act as the dungeon master? Until the recent wave of reasoning models, the answer was mostly 'nothing coherent', but Claude 3.7 with thinking is very good at this! It will probably get rate limited with minimal traffic, but I have a demo up at https://lairsandllamas.com

I'm building https://www.themoonlight.io/en with a small team of four - it s an AI aided PDF reader, designed to make research papers more accessible :)

Lately, I've seen a growing interest in academic content from non-researchers, so I'm focusing on features like automatic summarization and LaTeX math explanation to lower the barrier. I hope this helps more people engage with research and ultimately push global innovation forward.

If anyone is interested, here's a quick 1 minute demo: https://www.youtube.com/watch?v=L1i8Yp_APbg Feedback is always welcome!

Thank you!

Working part-time on Lungy, the breathing app I developed whilst working as a doctor during COVID - https://www.lungy.app/

Also, very interested in synthetic biology atm, I’m taking HTGAA - https://www.media.mit.edu/courses/htgaa/

How did you get access to HTGAA? I’ve really wanted to take this course but all of the videos and resources seem locked

lukko 3/31/2025||

Are you able to access last year's: https://howtogrowalmostanything.notion.site/

Otherwise, look out in Jan / Feb next year for applications to be a 'committed listener'.

djsamseng 3/31/2025||

Yes! This one works. Thank you so much!

Working on a tool to remember things I read.

You select some text with your phone and share it with my app, then the shared text is reformulated to a flashcard (with the help of a llm).

You can then browse your flashcards in the app, but I’m also working on ways to show the cards to you with less friction: Like on the phone lock screen or on the face of your watch.

This is really cool. Any chance you can make the backend selfhostable with ollama as an option for the LLM?

Two things:

1. A Haskell client library for Tigerbeetle db: https://github.com/agentultra/tigerbeetle-hs

2. smolstore, the smallest possible event sourcing database: https://github.com/agentultra/smolstore

I'm working on Cali Challenge. A calisthenics workout app with a daily challenge that gradually increases in difficulty. It guides you through the different progression levels of core calisthenics moves like push-ups, pull-ups, and dips.

greatbahram 3/31/2025||

This is a cool idea; like to give it a try!

jcjmcclean 4/1/2025||

Thanks! I'll pop you a DM on here when I've got it up on the app stores.

gsala 3/30/2025||

I would use that!

jcjmcclean 3/31/2025||

Awesome! If you don't mind, I'll drop you a DM when I've got a beta version ready.

quibono 3/31/2025||

Please count me in too!

jcjmcclean 4/1/2025||

I will, thanks for the interest!

Working on getting my life back together.

I've been more or less sick for the most of Q1/25. Always some cold, coughing, sometimes worse. Went to work nevertheless most of the time (stupid, I know), because... I don't know. Guess I think work is more important because it gives me the feeling of being good at something and worth it.

Didn't take much care about eathing healthy, getting my gym routine done or even enough sleep. Lots of other stress, too.

Not sure how much I can change from Q2/2025 on but I'll have to start optimistic. Some clouds are clearing up, some problems and issues are gone or being taken care of, can only go up from here.

All the best for everyone.

thank you for sharing this, as someone going through a rough Q1 too, it's nice to hold this feeling with someone else across the universe as well. Onwards and upwards.

martin_a 4/1/2025||

You're welcome. Would have loved to tell something more positive.

nabeards 3/31/2025|||

Going to work while sick exposes everyone there to whatever you have. That’s a very careless act.

martin_a 4/1/2025||

Yes, that's true, not very responsible, nothing to argue about.

I'm working on the next big version of my timer app[0]. I'm adding a Watch companion app.

While doing that, I realized that I actually have some fundamental issues with my architecture.

When I find myself playing whack-a-mole with bugs (especially with a Watch app), then I know the fundamentals are suspect (the app is one that has been in the App Store for over a decade, in one form or another, so it does have some bitrot).

So I'm redoing the engine, and will probably substantially rewrite the app, itself.
