I just came across an open source AI note taker built for anyone who lives in meetings, called Prismical.
It is free and the code is public, here is the Github link for reference.
The differentiator is the capture model: it records straight from your system audio, so nothing ever joins your call and no one on the other end knows you are taking notes. It is local first too, so the transcription can run on your own machine with Whisper and your audio never has to leave your device unless you choose otherwise. In my test it gave me a live transcript with speaker labels and turned it into a summary with decisions and action items in a few seconds.
You also get bring your own keys, local models, and an MCP server so Claude or ChatGPT can read and write your notes. Open source and free is rare in this category, which makes it easy to recommend a try.
Where it needs polish: my very first recording came back empty and only worked on the second attempt, so there is a warm up wrinkle on day one. The default transcription runs on their cloud and counts against the free 300 minute monthly cap, so heavy users will want local models or their own keys.
The calendar connection is also one directional: it imports your meetings so you can record them, but it cannot push your action items back onto your calendar.
Outbound webhooks do exist, though the payload only carries ids and titles, so you need the paid API (Premium is 10 dollars per seat per month) to do anything useful with it, and the MCP integrations I looked at (Gmail, Zoom, Asana) were erroring on my account. None of this stops me using it right now, and for private, bot free meeting notes it already earns a place in my kit.
