Why I built it
A freelancer friend lost a four-figure project because the client ghosted right after the work was done — no NDA, no signed service agreement, just a Slack thread and good faith. Lawyers wanted $300+ to draft a one-page NDA. Templates from random PDF sites were either out of date or copy-pasted to the point where their clauses contradicted each other.
So I built AI Contract Generator — a free AI contract generator tool that turns plain-English descriptions into a real, downloadable PDF contract in about a minute.
What it actually does
You describe what you need in natural language:
"Two-month service agreement between me (freelance developer) and an early-stage startup, net-15 payment terms, mutual NDA on tech stack details, 30-day kill-fee clause."
The AI picks the right template (service / NDA / employment / partnership / rental), drafts the clauses, and drops you into an inline editor where you can change names, dates, payment terms — anything — and export to PDF.
Why I bothered
Most "free legal template" sites are SEO traps. You search "free NDA template", land on a PDF that:
- has a placeholder city in California even though you're in the UK,
- references "Exhibit A" which doesn't exist,
- has the wrong jurisdiction in the dispute resolution clause.
I wanted a tool where:
- You don't need to know legalese. Describe the situation in your own words, the AI translates.
- The output is editable. Generated clause too aggressive? Edit it inline. Want to soften the kill-fee? Change one line.
- It's actually free to try. No card before you see the output.
The stack (for the dev nerds)
- Next.js App Router on the front
- LLM orchestration with structured output for clause generation (so the JSON schema is enforced, not vibes)
- PDF rendering server-side so layout stays consistent
- Inline editor synced back to the contract JSON so "edit then export" round-trips cleanly
The trickiest part wasn't the model — it was the constraint encoding: making sure when someone says "net-15 payment, late fee 1.5% per month", the resulting clause reads as a real lawyer would write it, not as ChatGPT word soup.
Who it's for
- Freelancers who need NDAs and service agreements without paying $300/contract
- Landlords drafting rental agreements
- Founders sealing partnership / employment deals
- Small business owners who need a contract today, not in two weeks
Try it
It's free to try — no signup wall before the first contract. If you've ever spent an hour copy-pasting clauses out of a PDF you don't trust, give it a go: contractgenerator.net.
