Things to ask
Common questions
Is Muse a replacement for an IDE assistant?
No — it complements it. Muse shines in the browser: docs, issues, PRs, tutorials and dashboards, where your IDE assistant can’t see.
Can I use Muse on GitHub?
Yes. Turn on “This page” on a file or PR, or select code and right-click “Explain this code”.
Is my code private?
Code is processed to generate an answer and not stored on Muse servers. History stays in your browser.
