Zero cloud risk. Always.
Your clipboard history stays on your Mac. No iCloud. No servers.
Fuzzy search as you type.
Type a few letters in order — "gco" finds "git commit" — and your clips re-rank on every keystroke. Technical aside: a linear-time fuzzy scorer over an 8 KB prefix per clip keeps search cost flat, no matter how long your clips are.
Why your clipboard history should never leave your Mac
Copycat has no cloud sync, no servers, no accounts — on purpose. In a typical day you copy passwords, two-factor codes, API keys, bank numbers, medical details, and contract terms. That history is too sensitive to leave your Mac.
Sync means your data has to leave your machine: servers, accounts, breach surfaces, and terms of service you never read. Copycat can't sync even by accident — macOS runs it in the App Sandbox with no network access at all.
Every clip stays on your Mac, encrypted at rest with AES-GCM, keys held in your macOS Keychain — the same vault protecting your passwords. Password manager entries are skipped automatically.
This isn't a setting. It's the foundation of Copycat.
Other clipboard managers. And then there's Copycat.
We checked. Here's how it stacks up.
