I built an AI Contract Generator so freelancers stop drafting NDAs at 1am

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 Templates from random PDF sites were either out of date or copy-pasted to the point where their clauses contradicted each other.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.

Feedback welcome — what contract types do you want next? I'm reading every comment.
