I had enough of paying for recording my meetings

I had enough of paying for recording my meetings:

either with time when searching across recordings between Zoom and Meet, if I have the luck to find the one I'm looking for,
or with money in apps like Krisp.

So I built mono – a local-first recording app that transcribes lets you search across all your recordings kept in one place. Ask it "what did we decide about project X?" and it finds the answer, even if nobody said the word "timeline."

Works with any audio sources: Zoom, Teams, Meet, desktop WhatsApp, anything else.

Everything runs on your machine, including lightweight AI models. No cloud, no bots in your calls, no monthly fees. Just your recordings, fully private and searchable forever.

Initially build just for my personal use, I already use it to record therapy sessions, which helps me track repeated patterns and stay focused on progress over time.

Then I realized it could be useful to others, so I decided to release it at a fraction of what similar apps cost.

Both Mac and Windows apps will be available after release.

I made a free webapp for learning piano notes

Excited to share what I built to help beginners like me learn the keyboard and notes on the staff faster.

The whole thing is portable (no internet needed after first load) if you download the repo from GitHub. Or just open the webapp. No installation. No account. Just you and the notes.

If any of your friends are learning the piano or musical theory in general, please share it with them.

Let me know what you think!
