Where is the in-app “Usage tutorial” link?

You want the official tutorials / product page without hunting the URL manually.

1. Step 1 — From the main mail toolbar

   When at least one account exists, look next to New mail. Click Usage tutorial (book-style icon). Your default browser opens https://www.winappcenter.com/products/neat-mail/.

2. Step 2 — From the welcome screen

   If you still see the welcome layout (no accounts), the same button appears under Add an email account.

3. Step 3 — Offline HTML manual

   This repository ships a static manual under docs/neat-mail-ai-manual/ (open index.html in a browser). Host it on your site if you want a copy beside the product page.
