Idea Forge Pro
A free browser-based tool that puts a startup idea through seven validation gates and tells you which one it fails, before you write a line of code.
Idea Forge Pro is a static, client-side tool built by Deliberon that runs a startup idea through seven validation gates (buyer, problem, offer & price, value artifact, pre-build test, channel, and builder spec) and reports exactly which gate the idea fails before any code gets written. It is BYOK by design: you supply your own API key for a provider such as OpenAI, OpenRouter, DeepSeek, or Groq (or any OpenAI-compatible endpoint), and the idea plus the key travel directly from your browser to that provider, with nothing stored on Idea Forge Pro's own servers. The tool is free to use and outputs a downloadable Sell-Kit, containing a deal memo, validation plan, value artifact, and builder spec, once an idea survives the gates.
