A bad contract rarely hurts all at once.

It shows up one missing term at a time. Scroll through the moments where vague language turns into a real business problem.

01

The payment never comes.

Timing, milestones, and late-payment terms were never made clear. The work is done, but the invoice is still open.

02

The supplier changes the deal.

Materials, delivery, or quality standards shift after production starts because the agreement never pinned them down.

03

They walk. Your contract lets them.

Scope, ownership, and termination were left open to interpretation. You only discover the gap when the relationship ends.

The problem usually starts with the clause that was never there.

FAQ

Questions we hear a lot.

Can I just use ChatGPT for this? +

You can. But ChatGPT does not know what it does not know, and neither do you when you are reading the output. It will not tell you about the clause it left out or the loophole buried in paragraph eight. Claustar is built on attorney-built templates, so there is a structural foundation a general AI prompt does not have.

Is this a law firm? +

No. Claustar is not a law firm and does not provide legal advice. We build documents grounded in attorney-built templates and flag clauses worth a second look. The AI walks you through your situation. It does not make legal decisions for you.

What happens if I need real legal advice? +

For high-stakes situations, we recommend having a licensed attorney review the final document. Because Claustar has already handled most of the drafting, an attorney is reviewing rather than building from scratch, which keeps that cost far lower.

What kinds of agreements can I build? +

Freelance contracts, supplier agreements, brand partnerships, NDAs, co-packer agreements, service agreements, influencer contracts, and more. If it is a business agreement, Claustar can help you build it.

What happens when I upload a contract someone sent me? +

Claustar walks the document clause by clause and flags every clause worth a second look. Vague terms, missing protections, one-sided language. You see exactly what you are signing before you sign it.

Is my information secure? +

Your documents are encrypted and private. We do not share, sell, or use your agreements for any purpose outside of generating your document.

Do I need a credit card to start? +

No. Your first document is completely free. No card, no commitment.
