You can read every note twice and still miss something.
— estimator, r/estimators, 2026.
Every solo GC, small-firm contractor, and estimator recognizes the feeling. Prevaldi gives you the two things that actually help: free browser tools for the daily drag, and written operations reviews for the bigger picture.
“We found around 0.4% in gaps that were super avoidable if we had more time.”
“By the time I write up the Change Order, the GC denies it because it wasn’t documented in time.”
Data handling
When you use any tool on this page, your input passes through our server to Anthropic’s API and back. We don’t log the content. Anthropic’s API is configured with Zero Data Retention.
Construction tools are designed for the text you already work with — bid documents, spec notes, change descriptions. Paste what you have and get something useful back.

Construction Operations Review — [Firm redacted]
11 pages · delivered within 48 hours
The intake form asks about how you run your firm — your bidding volume, your software, where the friction shows up. It does not ask for project names, sub rates, client information, or financial statements. Free while Prevaldi is in beta. No upsell at the end.

These aren't live yet. Add your name for the one you'd actually use and we'll tell you when it ships.

Positioning
Procore’s enterprise tier is priced for GCs running $50M+ in annual volume. For the 90% of contractors working below that — solo GCs, small firms, specialty subs running lean — it is a line item that never clears the first conversation.
Prevaldi serves that market with focused tools and written reviews priced at what a lean operation can sustain. No account. No Procore replacement. No all-in-one platform. Focused single-task tools for the work that actually erodes margin.
How it works
You fill out the intake form. A PDF lands in your inbox within 48 hours. If you have follow-up questions, reply to the email and get a written answer back, usually within a day.
Paid audits, once live, follow the same process with a 5-business-day turnaround. The scope and depth are the same either way — only the focus area changes.
