Save why a prospect mattered before the context disappears.

Signal Notebook is a private pre-CRM notebook for manual prospect research.

Paste notes, source URLs, profile snippets, email signatures, or research details into the Chrome extension. Save prospect context locally in your browser, then review follow-ups later.

Install from Chrome Web Store

No account. No scraping. No automation.

How it works

1. Paste manually

Copy or type a note, source URL, profile snippet, email signature, or research detail into the extension popup.

2. Save context

Capture who they are, why they mattered, where you found them, and what you might do next.

3. Follow up later

Review prospects by status, tags, pipeline, and follow-up date. Export your data anytime.

Built for the pre-CRM stage

Signal Notebook is for the “maybe later, but don’t forget why” stage.

Use it before a contact is ready for a full CRM.

You can:

• Save prospect cards from text or URLs you manually provide
• Capture source, signal, notes, tags, status, and follow-up dates
