About this extension
tabsnap is a free browser extension by vøiddo that does one job: it takes a snapshot of every tab you currently have open, in any window, and lets you copy or download the list as plain text, markdown, JSON, or a ready-to-paste readme file.

WHY
Tab graveyards happen. You open 47 tabs while researching something and then have to share, archive, or just reset. tabsnap turns that mess into something you can paste into Notion, drop in a Slack thread, attach to a ticket, or commit as part of a project README.

OUTPUT FORMATS
· markdown — nested list grouped by window, with hostnames as section headers.
· plain text — one tab per line, title + URL.
· json — structured array, ready to feed back into another tool.
· readme.md — full markdown document with a domain-summary table at the top, ready to drop into a repo.

OPTIONS
· group by window (default on)
· include / exclude pinned tabs
· include / exclude incognito windows
· current window only

PRIVACY
tabsnap reads tab titles + URLs only when you click the toolbar button. Nothing leaves your device. No backend. No telemetry. No analytics.

PERMISSIONS
· tabs — required to list open tabs (title + URL only)
· downloads — required for the “Download” button to save a file
· storage — required to remember your popup preferences across sessions

OPEN SOURCE
MIT-licensed. Source: github.com/voidd0/tabsnap.

Built by vøiddo, a small studio shipping AI-flavoured products, free dev tools, Chrome extensions and weird browser games.
