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.

CrowNest gives coding agents real isolated Linux sandboxes: create a machine, run code, install packages, stream stdout, expose a private browser preview, collect artifacts, then tear it down. Unlike generic serverless or long-lived devboxes, it is built for agent workflows across SDK, CLI, MCP, Python, REST, and Vercel AI SDK tools.

Tap record, say what's on your mind, and get back a real note: clean headings, key points, next steps. No typing, no tidying. Export to Notion or email to yourself.
