Frequently asked questions

Is the AI cost estimator free?

Yes. You can build an estimate with the AI assistant for free, with no login required. Creating an account lets you save, add full price detail and measurements, and export to Excel or BC3.

Where do the prices come from?

Line items are priced against Omnicost's construction cost catalog, sourced from multiple real suppliers and updated continuously — not invented by the model.

What's the difference from the full version?

The lite estimator builds a flat list of line items. The full version adds chapters, price decompositions, detailed measurements, versioning, collaboration, and exports.

Do you store my estimate?

Your estimate is kept temporarily so you can come back to it. Sign up to keep it permanently and turn it into a managed project.
