## How to use Idea Evidence Check

1. Move each of the six sliders to what you can prove today, not what you hope is true.
2. Score pain, observed evidence, customer access, willingness to pay, founder advantage, and speed to test.
3. Read the Evidence score and verdict on the right.
4. Work through Test these assumptions next, starting with the first one.

**Tip:** A confident story without observed behavior is deliberately capped, so score evidence conservatively.

The tool itself is interactive: open [Idea Evidence Check](https://launchaf.com/tools/idea-check) in a browser to use it.
