Legal documents that actually protects your business.

Claustar is an AI-powered contract drafting platform built for founders, freelancers, and small business operators who can't justify $3,000 in legal fees every time they need a contract. You describe your situation, we ask the right questions, and you walk away with a structured, ready-to-review draft in minutes. Not a generic template. Not a chatbot. Something actually built for your deal.

No. You describe what you're trying to do in plain English. Claustar interviews you, explains what each clause actually means, and flags anything you should pay attention to. You make every decision. We just guide you so you don't miss anything important.

Here's how we think about it: we start from attorney-reviewed templates, then build your contract clause by clause based on your specific situation. You're not getting a blank form with your name swapped in. You're getting a structured draft that reflects your deal. For most everyday contracts, that gets you 90% of the way there before you've spent a dollar on legal fees. For high-stakes agreements, you can export a clean draft and take it to an attorney for a fraction of what a full build would cost them.

Employment agreements, contractor agreements, NDAs, IP assignment agreements (PIIAs), offer letters, and client service contracts. We continue to add more documents as we grow.

LegalZoom gives you a static template. ChatGPT gives you text it generated on the spot with no guardrails. Claustar interviews you, builds your contract clause by clause, explains what each section actually protects you from, and surfaces gaps before you sign anything. The templates we build from were reviewed by attorneys. The AI doesn't guess; it works from a structured foundation and adapts it to your situation. Think of it as what you'd get if ChatGPT and LegalZoom built something together with an actual attorney in the room.

That's your call. Our templates were built and reviewed by licensed attorneys. For a straightforward NDA, contractor agreement, or service contract, most operators don't need additional review. For anything with significant financial exposure, complex IP, or unusual terms, bringing in an attorney to review your draft is a smart move. The difference is you're arriving with a clean, detailed draft instead of starting from scratch. That alone cuts their billable time significantly.

Your contracts are yours. We never train our AI models on your personally identifiable information (PII). Please refer to our privacy policy for more information.
