How to review a pull request or a code change in ChatGPT.
Add the Veridu app, paste a GitHub pull request link or a diff, and ask ChatGPT to review it with Veridu. You get back pass, review or block, and findings with the location in the code and the evidence for each.
Open Veridu in the ChatGPT directory, add it, and sign in to Veridu when ChatGPT asks (GitHub, Google or an emailed code). Connecting does nothing until you ask.
In a new chat, choose Veridu (or mention it by name), then either:
- Paste a GitHub pull request link and ask "review this pull request with Veridu".
- Or paste a diff and the full changed files and ask "verify this change with Veridu".
Public repositories work right away. For a private one, link it first at veridu.io/repos.
An outcome (pass, review or block) and findings with the location, severity and the evidence behind each. A review can take a few minutes; if it is still running, ask ChatGPT to check on it.
Can ChatGPT see my repository?
Not through Veridu. For a pull request, Veridu reads it from GitHub and traces the code it affects; for a pasted change, it reviews only what you paste. A private repository has to be linked on veridu.io first, with the GitHub App or a fine-grained token.
How is this different from asking ChatGPT to review the code itself?
Veridu runs its own independent reviewers on the change, outside your chat. For a pull request it also finds the code the change affects, such as callers of a changed PHP function, and checks the change in that context. Findings without evidence are dropped, and only problems the reviewers confirm can block.
Does it post anything to GitHub?
Not from ChatGPT. The review comes back in the chat. Posting reviews on pull requests is what the Veridu GitHub App does, if you install it.
Does it use my ChatGPT plan?
No. Veridu's reviewers run on Veridu's own model access. A review counts against your Veridu reviews.
What does it cost?
The free tier includes up to 20 reviews a month, with no card. A private repository needs a paid plan.
Does it work in Codex too?
Yes. The same app works in Codex, where your agent can send its own changes before it commits.
The same works in Claude: code review in Claude. For agents that write the code, see verify Codex changes and the MCP server.
