Yes. Corten is AI proposal software for contractors that drafts your client proposal from the winning bid numbers on your bid sheet, with the scope of work written from the subcontractor quotes you already collected. You review and edit everything, then export a branded proposal to Word or PDF on your own letterhead. No retyping.
AI proposal software for contractors turns your priced bid into a client-ready proposal automatically — Corten builds it from the winning trade numbers on the bid sheet and drafts the scope from your subs' quotes, keeping every dollar consistent with what you bid.
Drafts from the winning numbers
When you select the winning subcontractor bids on the trade worksheets, those numbers roll up to the bid sheet and the proposal drafts itself from that total — with canonical bid-total math, markups, and profit already applied.
Scope written from your subs' quotes
Corten reads the subcontractor proposals and vendor quotes you already have and drafts the scope of work in each trade from that language, so the proposal describes what was actually bid instead of a blank template.
Fully editable before it goes out
Every AI-drafted line is queued for your review, not sent automatically. Adjust wording, add exclusions, and set your terms — you approve the final proposal.
Word / PDF export on your letterhead
Export the finished proposal to Word or PDF with your company letterhead and branding, ready to email or print for the client.
Connected to the rest of the job
Enter once and it flows: the same numbers move from bid to proposal to budget to schedule to invoice. Approved estimates convert to jobs and approved change orders roll into the budget automatically.
Frequently asked
Does Corten write the proposal for me?
Yes. Corten drafts the client proposal from the winning bid numbers and writes the scope of work from your subcontractors' quotes. You review and edit it, then export to Word or PDF.
Does Corten do drawing or quantity takeoff?
No. Corten is not a takeoff tool — it does not read blueprints, count symbols, or measure plans. It works from the subcontractor bids, vendor quotes, and other documents you already have; takeoff is an upstream input you bring into Corten.
Can I edit the proposal and use my own letterhead?
Yes. Everything the AI drafts is queued for human review before anything is final, and you export the finished proposal to Word or PDF on your own company letterhead and branding.
