The Opportunity

Problem

Indie hackers face prohibitively high costs and excessive complexity when hiring lawyers for basic contracts and NDAs needed to protect their small businesses.

Solution

Describe your deal in natural language (e.g., 'NDA for my SaaS co-founder with 2yr non-compete'), and AI generates a legally-sound, customizable contract. Edit, sign, and store instantly. Powered by fine-tuned models for indie scenarios.

Target Audience

Indie hackers and bootstrapped small business owners building SaaS or digital products solo or in tiny teams

Differentiator

Conversational AI skips forms—perfect for non-lawyers who hate templates.
