The Autter standard already has support across the agent tools developers use every day.

First install, first answer.

No new dashboard to learn. Commit normally and Autter shows the human-to-AI split immediately.

A record agents cannot explain away.

Autter records explicit line-level attribution as the code is written, then carries that context through normal Git history.

No workflow change

Prompt, edit, commit, and push exactly as you do today. Autter attaches attribution in the background.

Local-first by default

Use the open source CLI fully offline, with no account required and no prompt upload required.

No git hooks

Autter does not wrap Git or rely on per-repo hooks, so normal Git commands stay fast.

Git-native record

Line attribution is stored with Git Notes, giving teams a durable record across common Git operations.

Install once. Keep committing.

Start local-only, then connect to the Autter platform when your team wants dashboards, prompt search, and audit history.
