QuarterMill

A world model with receipts.

V1 Shipping May 28th 2026 ·

The verified knowledge infrastructure for the next age of discovery.

The internet made knowledge more accessible and less trustworthy. LLMs made the corruption catastrophic. QuarterMill is the correction.

QuarterMill is a closed-loop provenance and audit infrastructure for AI-powered knowledge systems. Every claim is validated against source material before it reaches the user. No answer exists without traceable provenance.

A glass box where reasoning can be traced. Not the black box of tokenization where knowledge surfaces without lineage.

i. Not a ChatGPT wrapper.We're infrastructure, not interface.
ii. Not a foundation model.We make them verifiable.
iii. Not a search engine.We make AI search trustworthy.
iv. Not a database.We sit on top of them.
