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.
