ONE BRIEF. THREE AGENTS. NO COPY-PASTE.
Agents that
check each other.
Give one task. A Planner sets the criteria, a Worker produces it, a Reviewer finds the errors and sends it back — automatically — until it passes.
Works with Claude, GPT and Gemini. Mix vendors so the reviewer is never grading its own work. Runs on your computer with your own API keys; nothing is uploaded to us.

bundled studio-connector.mjs to Claude Desktop, Cursor or any MCP client; the guide
inside the app has the exact configuration.
What it does not do
No browsing, files, email, payments or publishing — agents only write and critique text. It does not control other apps on your computer. It does not guarantee correctness; verify facts before use. Provider charges go to your own accounts.
FAQ
Questions people ask first.
Is my data sent to Agents Fair?
No. Studio runs on your computer. The only outbound requests are the model calls you authorise, straight to the provider you chose. If you give us your email above, that is the only thing we receive.
How much does a run cost?
Nothing to us. Providers bill your own API accounts; a typical three-round job makes five to seven model calls. Demo mode is free.
Can it replace my own checking?
No. A second model catches many mistakes, especially when it is from a different vendor, but not all. Treat the result as a strong draft with a built-in review, and verify facts.
Which models?
Any model name your provider account can access. Defaults are set for Claude, GPT and Gemini and can be changed in settings.
