</a>What the jury does
Ask from Claude or from Dual's web app. Each AI checks one thing and the judge keeps only what holds up.
«Before committing, run this change through review_many»
- ClaudeCalls Dual with the code
- PanelAIs from other brands, each with its own job
- JudgeChecks every finding against the code
Claude gets only the confirmed issues and fixes them.
«Review pull request #42 in my repo before I merge it»
- review_prReads the description and the diffs
- PanelSecurity, logic, edge cases…
- YouDecide what gets fixed
A list from most to least serious, with the exact line.
«Is there any injection or data leak in this endpoint?»
- SecurityLooks for unvalidated input
- DataChecks what gets stored and what leaks
- JudgeDrops what the code already handles
No false alarms: every issue quotes the code.
«My page shows up blank and I don't know why»
- RunRuns your code
- FixReads the error and explains it
- CodeFixes it and the Reviewer checks it
You know what broke and it's fixed and reviewed.
A real review, not an opinion
For what matters, up to 12 AIs read the same answer at once. Each checks something different and a judge merges what they found, without duplicates.
The model that wrote a bug rarely sees it: that's why other brands review. Still, check what matters yourself before you ship it.

Two ways to use it
- Claude keeps coding and, when it matters, asks Dual for a jury of other brands.
- It gets the issues already checked by the judge, most serious first, and fixes them.
- Every review is saved in Dual, with what it cost on your keys.
- A chat another AI reviews, or panels that hand work over: plan, code, review.
- Work on your real repo and get the changes as a Pull Request.
- On a computer or a phone, nothing to install.
- Keys encrypted with XChaCha20-Poly1305; they never go back to your browser.
- AI calls are made from the server, not from your browser.
- Passing a prompt never spends tokens: you decide when to send it.
- Every database query is scoped to your user.

Start freeFrequently asked questions
How does it connect to Claude?+
In claude.ai (Settings → Connectors) or in Claude Code add Dual's connector address and press «Allow». Nothing to install: Claude calls Dual when you ask for a review, and Dual uses your keys.
Why other brands instead of Claude reviewing itself?+
Models from different families get different things wrong, and the one that wrote a bug usually doesn't see it. So the panel mixes brands and the judge keeps only what it can check in the code.
Does it replace a developer?+
No. AIs make mistakes, which is why here one reviews the other's work; even so, check the result yourself before using it for anything important.
Do I have to pay for the AIs?+
Not necessarily. With OpenRouter you get free models (with the daily limits OpenRouter sets, not Dual). If you want paid models, you pay each provider directly, with no markup from us.
What if I don't code?+
You can also use Dual's web app: in Simple mode you talk to one AI and another brand reviews what it did, and you try it right away.
Can I work on my GitHub project?+
Yes. Connect GitHub, import your repository (private ones too) and push the changes as a Pull Request on a new branch. You decide whether to merge it.
Are my keys safe?+
They're encrypted on the server as soon as you save them and never go back to your browser, not even encrypted. You can remove them at any time and they're deleted for good.
Can I use it on my phone?+
Yes. On mobile you see one panel at a time and swipe to switch; a dot tells you when another panel is answering.
