Barzero.ai
Privacy first AI-assisted contract draft and review.
Enterprise-grade AI contract review and creation. Zero trust. Zero knowledge. Zero retention.
Hey Product Hunt 👋
The problem: Lawyers review contracts in Word, mark them up by hand, and pray no confidential language leaks into whatever AI tool they pasted the draft into. Most "AI contract review" tools keep your document on their servers, train on your data, or both. That's a non-starter for anyone under ABA Formal Opinion 512 or a client NDA.
What BarZero does: Clause-level contract review with a playbook you define — your positions, your fallbacks, your red lines — and a tracked-changes .docx redline you can drop straight into Word.
What makes it different:
Zero Data Retention on every request. Your contract and your playbook never get stored, logged, or used for training. Parsing happens client-side before anything touches the network.
Your playbook, not ours. Upload once, review everything against it. No generic "industry best practices" — the output matches how your firm negotiates.
Redlines that open in Word. The output is a real tracked-changes .docx, not a chat transcript you have to hand-copy.
Batch mode for folder reviews, Google Drive / OneDrive / SharePoint sources, and a CLI for the ops-minded.
Why I built it: I kept watching lawyer friends copy-paste NDAs into ChatGPT and hold their breath. The tooling for them was either a $50k/seat enterprise platform or a consumer chatbot with none of the guarantees their profession requires. There wasn't a middle.
Pricing: Starts at $79/mo solo, team plans up to 8 seats, enterprise on request. Beta pricing is 50% off for the lifetime of the subscription for anyone who signs up during the launch window.
What I'd love feedback on:
Does the ZDR + client-side parsing story land, or does it need more proof-work?
For the lawyers here — what's missing from the playbook model?
Pricing: is the Zen tier priced right for solos?
I'll be here all day answering questions — AMA about the tech, the privacy model, or why the tiers spell Z-E-R-O.
