How it works
A short path from a social post to a source you can open.
-
Find the claim
The AI uses Meta's Muse Spark models to find each number, period, and comparison in the post.
-
Open the filing
It looks up the company's SEC filing for the same company, number, and time period.
-
Code decides
Code, not the AI, compares the numbers and gives the final True, False, or Can't check verdict.

The fixes were made after seeing these mistakes, so this is a regression check, not a new test score. Accuracy changes are within noise; false 'supported' answers dropped to zero.

Why you can trust it
The source and the rules stay visible.
- Every answer links to the filing.
- The AI cannot change the numbers it quotes. If the quote changes, it is rejected.
- We publish our own mistakes in BUILD_LOG.md.
