Frequently asked questions

Is making the estimate online free?
Yes. You can create your AI estimate free to try it. You only go Pro if you want to quote without limits.
Do I need to sign up?
You can start describing the job and see the result without signing up. You create an account only to save the estimate or send it to the client.
Where do the prices come from?
From reference prices by country (Chile, Mexico, Colombia, Peru, Argentina and Brazil), so you do not look them up by hand. You can always adjust them to your own values.
Does it work for my trade?
Yes: construction, remodeling, plumbing, electrical, painting, tiling, drywall, roofing and more. Describe your job and AI builds the right line items.
Can I edit the estimate?
Yes. Change quantities, prices and line items whenever you want, and the total recalculates automatically.
