## Atuin

Making your terminal magical.

Sync, search, and back up your shell history with end-to-end encryption. Ask Atuin AI for help without leaving your prompt.

Available for macOS, Linux, and Windows · bash, zsh, fish, and more.

### Atuin History

Shell history supercharged.

Sync, search, and back up your shell history with end-to-end encryption. The magical shell tool loved by developers worldwide.

- **Sync everywhere:** Your shell history follows you across machines, backed up and ready when you need it.

- **Private by default:** History is encrypted client-side, with self-hosting available when you want your own infrastructure.

- **Search rich context:** Find commands by text, directory, exit code, duration, hostname, and more.

### Atuin AI

AI as part of your terminal.

Atuin AI comes with the normal Atuin install and works inside the terminal you already use. Type `?` on an empty prompt to ask for help without leaving your shell.

- **Part of your prompt:** Install Atuin once, then open AI with the question mark operator on an empty prompt. No separate app, no copy-paste loop.

- **Knows your shell history:** Use command output, exit codes, directories, shell history, and more as debugging context.

- **Suggests and runs commands:** Ask a question, then run or insert the suggested command with one key. Atuin can run bash for context, and flags dangerous commands before they run.

### Getting started and hosting

History and AI ship in the same package — install once, run `atuin setup`, and both are ready in about two minutes.

```sh

curl --proto '=https' --tlsv1.2 -LsSf https://setup.atuin.sh | sh

atuin setup

```

Prefer your own infra? The sync server is open source — self-host it.

Yes. Atuin is open source, and you can self-host the sync server or use the hosted service. Atuin AI is free while in testing.
