TabCatcher is a tiny Microsoft Edge (and Chrome-compatible) extension that rounds up all your feral open tabs and herds them into a neat Markdown file — titles, URLs, descriptions, and all.

What it does

You click a button. Your tabs become a .md file. That's it. That's the whole thing.

More specifically:

Counts your open tabs and windows so you can feel something
Fetches <meta> descriptions from each page (optional — it does slow things down a smidge)
Groups tabs by window if you're the type who organizes chaos into labeled chaos
Stamps the export with a timestamp so future-you knows exactly when past-you had 74 tabs open at 2am

Installation

This extension isn't on the store (yet). Load it manually:

Clone or download this repo
Open Edge and go to edge://extensions/
Enable Developer mode (toggle, top-right)
Click Load unpacked and point it at this folder
Pin the extension and marvel at that little icon

Usage

Click the TabCatcher icon in your toolbar
Pick your export options
Hit Export Tabs
Save the .md file somewhere you'll definitely find it later

Export options
