Frequently asked questions

What does Defacta actually check?#

What format are results in?#

Structured JSON. Every verdict comes back as machine-readable fields, so you can gate responses, store results, or render them inline without parsing free text.

How do I integrate Defacta?#

Three ways: a REST API for backends and pipelines, an MCP server for agents and MCP-aware tools, and a browser extension for inline checks. Use whichever fits, or combine them.

Can an agent fact-check itself?#

Yes. Because Defacta exposes an MCP server, an agent can call it as a native tool and verify its own output before acting on it.

Does it work on any text, or only AI output?#

It is built for AI-generated text, but the verification pipeline works on any text you submit - useful for research and editorial review too.
