You open one tab. Then five more. An hour later you have twenty tabs open and no idea what led where. The insight from twelve clicks ago, gone.
There was never a map. Until now.

How it works
01
Install & activate
Add rabbithol to Chrome, pick monthly or lifetime, and paste the license key from your Polar receipt. No account signup required.
02
Browse with tracking on
Every tab you open is mapped to its parent automatically. Trails sync locally as you go. No save button, no cloud upload.
03
Search & explore trails
Use Instant search for titles and URLs, or Deep search (beta) to scan page content from the last 3 days. Click any result to open the full visual trail.
Features
Auto-tracking trails
Uses Chrome's tab API to map parent-child relationships as you browse. Trails save automatically to local storage. Toggle tracking off anytime from the popup.
Interactive visual tree
Click any node to see its URL, domain, what opened it, visit history, and child tabs. Jump back to the page in one click.
Instant search
Find pages instantly by title, domain, or URL across your entire local history. Press / to focus search from anywhere in the dashboard.
Deep searchbeta
Scans the actual text inside pages you visited in the last 3 days. Slower than Instant, but finds matches inside the page content itself.
Kits
Bundle URLs you open together: research stacks, exam prep, weekly reads. Launch every tab from the extension popup in one click, optionally in a new window.
License key, no account
Pay monthly ($6.99, 7-day trial) or lifetime ($49.99) via Polar. No account to manage. Data stays on your device.
