## About

Negative Space is a generative tool that scans YC company descriptions, embeds them into a vector space, and identifies the sparsest points. It then prompts Claude to write realistic startup concepts for those gaps, producing ideas that fit the market yet remain untapped. The workflow is fully automated and can be run locally or via a simple web interface.

## Questions

### How does Negative Space generate startup ideas?

It embeds YC company descriptions into a vector space, finds the sparsest points, and asks Claude to write a concise startup description for those gaps. The output is then compared against real companies to ensure novelty.

### Is the tool open source?

Yes. The embeddings, code, and a Claude skill are available on GitHub at https://github.com/nh66labs/negative-space.

### Do I need access to Claude to use Negative Space?

The current implementation relies on Claude to generate the startup descriptions, so you will need an API key or a local deployment that can run the Claude model.
