Always-on AI meeting notetaker with a self-erasing screen replay
Bubbles keeps a rolling, encrypted replay of your screen and audio on your Mac. Each new minute deletes the oldest, so nothing accumulates and nothing uploads until you save a clip.
Type a few fragments during the call and Bubbles' AI turns the transcript plus your jottings into a structured summary, owner-tagged action items and a full transcript.
The desktop app runs locally, so nothing appears in the participant list. A separate, optional notetaker can join scheduled meetings from your calendar on supported platforms.
Scroll back through the replay, trim exactly the moment that matters and share a link. Only the trimmed clip is uploaded - never the surrounding replay.
Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
