## 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.

- No data used for model training
- Enterprise-grade security

**Additional Features:**
- Advanced code suggestions with tracking
- CI feedback analysis
- Custom prompts and labels
- Static code analysis integration
- Priority support

**Pricing:**
- Free tier: 75 PR reviews/month per organization
- Paid plans for unlimited usage

See [complete feature comparison](https://qodo-merge-docs.qodo.ai/overview/pr_agent_pro/) for detailed differences.

## How It Works

The following diagram illustrates PR-Agent tools and their flow:

Check out the [PR Compression strategy](https://qodo-merge-docs.qodo.ai/core-abilities/#pr-compression-strategy) page for more details on how we convert a code diff to a manageable LLM prompt

## Data Privacy

### Self-hosted PR-Agent

- If you host PR-Agent with your OpenAI API key, it is between you and OpenAI. You can read their API data privacy policy here:
https://openai.com/enterprise-privacy

### Qodo-hosted Qodo Merge 💎

- When using Qodo Merge 💎, hosted by Qodo, we will not store any of your data, nor will we use it for training. You will also benefit from an OpenAI account with zero data retention.

- For certain clients, Qodo-hosted Qodo Merge will use Qodo’s proprietary models — if this is the case, you will be notified.

- No passive collection of Code and Pull Requests’ data — Qodo Merge will be active only when you invoke it, and it will then extract and analyze only data relevant to the executed command and queried pull request.

### Qodo Merge Chrome extension

- The [Qodo Merge Chrome extension](https://chromewebstore.google.com/detail/qodo-merge-ai-powered-cod/ephlnjeghhogofkifjloamocljapahnl) serves solely to modify the visual appearance of a GitHub PR screen. It does not transmit any user's repo or pull request code. Code is only sent for processing when a user submits a GitHub comment that activates a PR-Agent tool, in accordance with the standard privacy policy of Qodo-Merge.
