Every line carries a source + confidence
The estimate you can defend
Estibrain is AI estimating for the trades. Every line item shows where its number came from and how sure it is, with a running ledger of every assumption. No invented figures, ever.
14-day trial with 25 AI estimates.
Example estimate: 5 line items, each labelled with its price source. One line is an AI estimate at 92% confidence and one is flagged for review.

The ledger
Every line has a source
Estibrain prices in a fixed order, and tells you which one it used.
- Your price book first, always.
- Then supplier pricing, the city cost index and community data.
- AI fills only what's left, and it's labeled as an AI estimate.
- Low-confidence lines are flagged for review, never hidden.
- A person commits every send, PO, charge and delete.
