Paste

What Paste is

Paste is a private notepad and clipboard for syncing text, links, and code snippets across macOS, Linux, and Windows devices. Notes can be plain text, Markdown, or code, and frequently used notes can be pinned. The app supports offline work and reconciles changes when devices reconnect. Its site describes local search across 10,000 entries in under 30 ms. Devices can pair by QR scan, short code, or recovery phrase, and each receives a revocable signing key. Paste says content is encrypted on the device with XChaCha20-Poly1305 before storage or syncing, with keys derived from the recovery phrase. Optional relays store encrypted blocks and can see network metadata, but cannot read note contents or keys. The encryption envelope, sync engine, relay client, and verifier are open source; Paste also includes a verifier and standalone CLI. Desktop versions run through the Pear runtime, which is required for installation. Windows first launch fetches the app over peer-to-peer and may take about one minute. Paste is free and requires no account. iOS and Android are in development, and Paste does not provide anonymity or provable physical deletion of ciphertext kept on third-party disks.
