FacTool

General framework: Unifies factuality detection across knowledge QA, code generation, math reasoning, and scientific literature review under a common pipeline.

Tool-augmented verification: Calls external tools (search engines, code executors, math solvers) to verify claims rather than relying on the LLM's internal judgment alone.

Benchmark release: Releases an accompanying benchmark dataset plus a ChatGPT plugin implementation for hands-on experimentation.

Practical fact-checking: Provided one of the first end-to-end fact-checking frameworks suitable for deployment alongside LLM chatbots.
