Frequently asked questions
Are the Brixaz tools really free?
Yes. Every tool on this page is free with no signup, no email gate, and no paywall. Brixaz makes money elsewhere — the tools exist so more people buy and sell locally.
Do I need an account to use a calculator or generator?
No. Calculators and generators run instantly in your browser. You only need a free account if you decide to post a listing afterwards.
Is what I type stored anywhere?
The calculators and document generators run in your browser — names, prices, and addresses you type into them are not saved on Brixaz servers. Tools that use live listing data or AI drafting say so on their page.
How accurate are the estimates?
Value estimates and rate guides are orientation, not appraisals: they combine typical US market ranges with your inputs. Legal-adjacent documents include state-specific notes with sources, but they are general information, not legal advice.
Can I post my item, rental, or service right after using a tool?
Yes — that is the point. Most tools end with a one-tap link that opens the free post form with your category and price already filled in.
