About Is Your AI Hallucinating?

How our white-box proxy model gives you a per-token hallucination score, including exactly what it costs. We ship an API that returns a hallucination score for every token that a frontier language model generates. Before describing how it works, here is the most important thing about it: the percentage score that we return is not actually the probability that the token is wrong. The obvious problem is that frontier models do not expose the hidden states that we would need to probe to reveal their thoughts.

About Selvedge

A local MCP server that AI coding agents (Claude Code, Cursor, Copilot) call as they work, logging the why behind every change into a SQLite file under .selvedge/ next to your code. Selvedge is a git blame for the why, a local MCP server your agent (Claude Code, Cursor, Copilot) calls as it works, recording the intent behind each change in the moment it makes it, not reconstructing it from the diff afterward.
