What it does
Cosign.ai helps founders and small teams handle legal work without slowing down. Generate YC-style SAFEs in minutes, analyze contracts with AI, and run product risk reviews directly from Slack or GitHub before shipping new features. Instead of generic “legal chat,” Cosign integrates into the tools teams already use and automates common legal workflows like contract analysis, drafting, and compliance review. Built for startups that need legal speed without legal bills.
Cosign helps small law firms turn client, matter, and source context into review-ready legal work with attorney control built in.

Outlit2024 · outlit.ai · ▲368Hey HN, I'm Leo, a cofounder at Outlit. After a year of coding, we have finally launched Outlit. Outlit was born post ChatGPT when we realized that AI can help empower everyday people to take on contract work and not have to rely on expensive lawyers all the time. Right now we are mainly focused on SaaS Agreements but have playbooks for other agreements (Partnership, Services, NDA). We also have a cool knowledge base feature that lets you semantically search across all your contracts. Would love some honest feedback. Thanks HN.
