CopilotChat
verifiedFreecopilot-chat.com
Tool that generates code from your test cases, iteratively refining an LLM's output until all the tests pass (TDD-driven).
What it does
CopilotChat generates code using a test-driven workflow. A developer defines test cases with inputs and expected outputs plus an optional requirement description; an LLM then writes code to match. CopilotChat validates the output against the tests and iterates with the LLM until every case passes.
