# Re-qualify existing leads

> Score the leads you already have again after changing a model.

Every section below does the same job: in the dashboard (Guide), from your code (API) or through an AI assistant (MCP).

## Guide — In the dashboard

Source: /docs/qualify/requalify

New rules score new leads straight away. To apply them to leads you already have, rescore them.

<DemoFrame guide="qualify-requalify" to="/score-model/{workspace}" />

1. **Qualify → ⋯ on a model.**
2. **Rescore recent leads** (the last 90 days).
3. **Make this the default** to choose which model scores new leads.
