I built an AI Contract Builder SaaS — selling it for $5,000 Теги: saas, nextjs, typescript, webdev

The unique feature

AI Contract Negotiation — paste any contract, choose your
perspective (buyer/seller/employee/tenant), and AI:

  • Gives a Favorability Score (0-100)
  • Flags every risky clause with severity (LOW/MEDIUM/HIGH/CRITICAL)
  • Writes counter-proposals: original text → suggested replacement → reasoning
  • Saves full renegotiated contract to your editor

DocuSign, PandaDoc, ContractBook — none of them have this.

  • Chrome Extension (Manifest V3) — right-click any contract text
  • Embeddable Widget — 1 script tag on any website
