1. Manifest

Manifest turns any webpage into a structured JSON map of what an AI agent can click, fill, and submit. One API call, no fragile selectors. Every action comes with resolved CSS/role locators, plus a requires field that encodes dependencies between elements (e.g. "select a plan before this button is clickable"). That's context aria snapshots don't give you. Python SDK, LangChain support, and an MCP server included. Built for anyone shipping browser agents.

9. Rewisp

Rewisp gives your Mac a memory. It reads your screen text on-device and remembers it for you. Catches promises like "I'll send it Friday" and reminds you until it's done. Ask "what changed since Tuesday?" and see exactly what's new. Search by meaning, not just words. Tracks numbers like weight or grades over time. Fills forms from your saved details — never passwords. One quiet 9 PM summary each day. Fully private: screenshots never saved, only text stays on your Mac.
