Savvy is a Mac app that reads the folder of documents you keep for a client and then shuts up for the whole call. It only says something if your own brief contradicts what was just said, if someone crosses a line you set beforehand, or if you press the button. Jaume Alavedra built it because whatever he needed mid-call was usually buried in something he'd already read twice, and every card it puts up cites the page, so you can check it before you say it out loud, and he's put the whole thing on GitHub under MIT.

Ojin turns one still photo into a face you can talk to, and the talking is where nearly all the work went. Specifically turn-taking: whether you've finished your sentence or you're just thinking. Mio tried on-device voice detection, cloud detection, ai-coustics and Deepgram and none of them held up on their own, so Ojin runs all four at once, and he'd rather you interrupted it, talked over it and put on a silly accent than sat there watching a demo.

GitNexus builds one graph of your entire codebase, every function and every call between them, so an agent that wants to know who calls this function gets a straight answer back and not a shortlist of maybes. Subham Kundu's building a company on it at Akon Labs. The engine's been on GitHub since last August, put up by a CS student who describes himself as someone who likes digging into the guts of systems, and it's on 45,824 stars now and plugs into Claude Code over MCP.
