I built a $12 AI tool that reads your contract before you sign

English is not my first language.
When I get a contract, I understand the words — but the legal phrasing, the buried clauses, the "notwithstanding the foregoing" — that stuff is designed to confuse even native speakers.
I tried using ChatGPT. It gave me 800 words of text I had to read twice to understand, with no clear answer on what actually mattered.
So I built Lintract.
You upload your contract, pay $12, and in 60 seconds you get:
→ A risk score 1-10
→ Every red flag ranked by severity — Critical, Warning, Note
→ Plain English explanation of what each clause actually means
→ The exact questions to ask before you sign
No walls of text. No subscription. No account needed.

While testing the payment flow I hit a bug where every paid user was getting redirected to the home page instead of their results.
4 hours of debugging later, the fix was one word.
Lemon Squeezy serializes all custom_data keys as snake_case in webhooks. I was reading sessionId. It was arriving as session_id.
Turned the whole debugging session into a free Claude skill so nobody has to go through this again:

If you're a freelancer, contractor, or just got a job offer — try it now while it's $12:

Would love feedback from the IH community.
