Why Cortex
Numbers you can stand behind
Most AI tools guess. Cortex shows its work — so the estimate holds up when a client, an adjuster, or your own margin depends on it.
Provenance on every line
Each line item carries its source and a confidence level, so you always know which numbers are grounded and which need a look before you send.
A living assumption ledger
Every assumption and exclusion is written down as the estimate is built — the paper trail that lets you stand behind the total in front of a client.
Plan-PDF takeoff
Upload a plan and Cortex reads the vector geometry, auto-calibrates the scale, and pulls measured quantities — no manual counting off the page.
Defensible proposals + e-sign
Turn an estimate into a good / better / best proposal, share a public client portal, and capture a legally-binding click-to-sign signature.
How it works
Quote to cash, in one place
- 01
Estimate
Describe the job or drop in a plan. Cortex builds a line-by-line estimate from your own price book — each number sourced, each assumption logged.
- 02
Propose & sign
Send a good / better / best proposal to a public client portal. Your client reviews the detail and signs online — no printing, no back-and-forth.
- 03
Invoice & get paid
Convert the signed proposal to an invoice, take card payments online, and re-baseline the contract cleanly whenever a change order comes in.
From the field
Built with contractors, not just for them
What our early-access partners tell us after their first few sent estimates.
“The first time a client challenged a number, I opened the assumption ledger and read it back to them. That was the whole argument.”

“I stopped rebuilding the same deck estimate from scratch. Cortex drafts from my price book and flags the two lines it isn't sure about.”

FAQ
Questions, answered
What makes a Cortex estimate “defensible”?
Every line item records where its number came from and how confident the model is, and the estimate keeps a running ledger of every assumption and exclusion. If a number can’t be grounded, Cortex flags it instead of inventing one — so you can explain and defend the total.
Which trades is Cortex for?
All of them. Cortex works from your own price book, so it fits any trade or contractor — as well as retailers and wholesalers quoting materials. You bring the pricing; Cortex brings the structure and the paper trail.
Do I need to build a price book first?
No. You can start estimating right away and build your price book as you go. The more of your own pricing and assemblies you add, the tighter and more grounded your estimates become.
Can my clients sign and pay online?
Yes. Share a proposal to a public client portal with good / better / best options, capture a click-to-sign e-signature, then convert to an invoice and take card payments — all without leaving Cortex.
How does the free trial work?
Every plan starts with a 14-day free trial and there are no contracts. You can change plans or cancel anytime from your billing settings.
