Walnut - Your Second Memory

Walnut is your second memory — a private place to keep the documents, photos, videos, links, notes and cards you don't want to lose, and to find them again in seconds. Everything happens on your device. Walnut reads your images and PDFs with on-device text recognition, transcribes audio and video locally, and indexes it all for instant full-text search. There's no account, no server, and no third-party AI — your information never leaves your phone unless you choose to back it up to your own iCloud.
