I create a room and share the link. Whoever opens it enters a name, knocks, and waits until I let them in, with no account. The call interface is custom, built on RealtimeKit.

Whoever wants to meet picks a free slot from the week, in their own time zone, and gets the invite by email, with Meet if the meeting type asks for it. Whatever is busy in Google Calendar isn't offered, and the email carries a link to reschedule or cancel without an account.

Claude Code, Codex and Cursor save and search memories over MCP. Every night an agent goes through them and proposes merges, rewrites and discards, but changes nothing: I approve or reject each proposal, with the before and after in view.

I save a link from the iPhone, a bookmarklet or by pasting it, and the server pulls out the clean text to read without clutter. An AI summarizes it, I search it by meaning, and I ask questions in a chat that cites every article.
