Idea Lint uses multi-agent AI debate to rigorously test your startup ideas. Get honest feedback, market research, and actionable PRDs in minutes, not weeks.
Why Idea Lint?
Real Research
Our Research Agent uses Google Search to find market data, competitors, and technical landscape. No hallucinations, just facts.
Adversarial Debate
An Advocate argues FOR your idea while a Critic argues AGAINST it. A Judge weighs both sides and gives you an honest verdict.
Actionable PRDs
Get a complete Product Requirements Document with technical architecture, milestones, and acceptance criteria. Ready to build.
Security & Guardrail Audit
Every PRD is reviewed by a dedicated Security Auditor agent checking for missing requirements, security gaps, and unrealistic assumptions.
Stateless & Privacy-First
Zero server-side database or user tracking. All idea history and PRDs are stored exclusively in your browser (IndexedDB) with instant JSON, CSV, and Markdown export.
Human-in-the-Loop Gates
You are always in control. Answer durable clarification requests, steer pivots, and approve or reject PRDs before any next step is taken.
Free Tier BYOK (Zero Cost)
Run complete multi-agent debates with a 100% free Google Gemini API key from Google AI Studio. No credit card required, zero platform lock-in.
How It Works
Submit Your Idea
Describe your startup idea in plain English. Optionally add URLs to articles, competitor sites, or research you've already found.
AI Research
Our Research Agent searches the web for market data, competitors, technical solutions, and relevant resources. You get a structured research brief.
Adversarial Debate
The Advocate argues why your idea will succeed. The Critic finds flaws and challenges assumptions. A Creative Agent suggests pivots and niches.
Judge's Verdict
The Judge weighs all arguments and gives you a scored verdict: PROCEED (build it), PARK (revisit later), or PRUNE (move on).
Your Decision
Review the verdict and debate transcript. Approve to generate a PRD, rebut with counter-arguments, or abort and try a different idea.
