Memento is a privacy-first workspace for notes, passwords, bookmarks and AI prompts. Notes, vault items, prompts and attachments are encrypted on your device with XChaCha20-Poly1305 before they sync, so our servers never see that content in plaintext. One app instead of three: Markdown editor, credential vault and smart link previews. Free during public beta. Next up: Claude-powered semantic search, summaries and tag suggestions that run on client-decrypted content.
