One list of notes, for you and your AI agents
Gravity is a notes app built on Andrej Karpathy's append-and-review note. Everything goes into one list, newest at the top. Old notes sink, and a swipe brings one back. You pay once, and your notes stay on your devices. New since the last launch: live Markdown, checklists, full exports, and a gravity CLI on the Mac that lets Claude Code, Codex or your own scripts read and write your notes. For iPhone, iPad, Mac and Android.
Gravity Notes launched on Product Hunt on 2026-10-18 and has 87 upvotes and 15 comments so far.
