Try It Now

Try the GPT-5 powered PR-Agent instantly on your public GitHub repository. Just mention @CodiumAI-Agent and add the desired command in any PR comment. The agent will generate a response based on your command. For example, add a comment to any pull request with the following text:

@CodiumAI-Agent /review

and the agent will respond with a review of your PR.

Note that this is a promotional bot, suitable only for initial experimentation. It does not have 'edit' access to your repo, for example, so it cannot update the PR description or add labels (@CodiumAI-Agent /describe will publish PR description as a comment). In addition, the bot cannot be used on private repositories, as it does not have access to the files there.
