44 tabs. 4 courses you were secretly taking.

Here is what you were really doing

The graveyard

Rest in peace, tabs

Every closed tab gets an epitaph. Resurrect any of them with one tap. After 30 days they are archived as plain bookmarks.

The grand mission

Your browser knows what you want to become.

Open tabs are unfinished intentions. Millions of people carry 50 of them around for months, feeling guilty. We want every pile of tabs to turn into progress instead of guilt.

Year 1

The extension for Chrome, Edge, Firefox and Arc-style browsers: dig, courses, close-what's-done, graveyard.

Year 2

Shared courses: the best cleaned-up tab piles on any topic, ranked by people who actually finished them. Phone browser tabs join the dig.

Year 3

An intention layer for the web: your browser notices a goal forming and offers the shortest real path, built from what thousands of people learned in the same order.

Blueprint

Why this is new

Tab managers (tab groups, suspenders, session savers, "close duplicates" tools) group and hibernate tabs by site or window. They never ask why the tabs are open. Tab Exhumer infers the intention behind a pile of tabs, names it in plain words, and orders the tabs into a learning path you can finish, closing each tab as you go.

The data it runs on

Source: the user's own open tabs: title, URL, when it was opened and last visited. Read through the standard browser extension tabs API (Chrome, Edge, Firefox).
Access: read locally by the extension. Titles and URLs are embedded on device. Page content is never read unless the user taps "read this tab" for a better lesson summary.
Limits and gaps: titles can be vague ("Untitled", "Home"). Browsers do not expose exact open time for old tabs, so age is estimated from session history. Mobile browsers do not allow extensions in most cases.
Fallback: paste a list of URLs or import a bookmarks folder; the same clustering runs on it.

1. The mission

Turn the guilt pile of open tabs into finished goals. Every tab you opened was a small promise to your future self; we help you keep the ones that matter and bury the rest kindly.

2. Why people can't resist it

Being seen. "You are planning a move to Lisbon" is uncanny and flattering; it names a goal you never said out loud.
Relief. Watching the tab counter fall from 44 to 12 feels like cleaning a room.
Completion. Ordered lessons with checkmarks turn a vague pile into a course you can finish this weekend.

3. How it works for real

Collect. The extension reads tab titles, URLs and timestamps through the tabs API.
Embed and cluster. A small on-device embedding model (or a fast cheap model like Gemini Flash via OpenRouter if the user allows cloud) groups tabs; duplicates and near-duplicates are merged.
Name the intention. A fast cheap model (Gemini Flash or DeepSeek) writes "You are trying to..." from the cluster's titles.
Order the lessons. The same model orders tabs from basics to advanced and writes one line on why each step comes where it does. Claude or GPT is used only for the optional "read this tab" summaries.
Close and bury. Marking a lesson done closes the tab and writes an epitaph from its metadata.

4. Cost per use

Free to run on a fast cheap model: a 50-tab dig is about 3,000 tokens, under $0.001. Fully on-device mode costs nothing.
Free: unlimited digs and courses. Paid ($3 a month): sync across browsers, Sunday digest, tab summaries, shared courses.

5. Growth loop

Finished courses can be shared as a link ("How I learned sourdough in 11 tabs"). Readers open the course, get the cleaned tab list, and are offered the extension to track their own progress. Screenshots of the graveyard are a natural post.

6. Risks and guardrails

Privacy: titles and URLs stay on device by default; sensitive domains (banking, health, email, work tools) are excluded by a built-in list.
Permissions: request only "tabs" and "storage"; no browsing history or page content.
Wrong guesses: every intention can be renamed or split; nothing is closed without a tap unless the user turns on auto-close.
Data loss: closed tabs stay restorable in the graveyard for 30 days.

7. MVP build order

Chrome extension that reads tabs and shows the popup with counts.
Clustering plus the one-line intention names with a cheap model.
Ordered course view with done-closes-tab.
Graveyard with restore, then the Sunday dig and share links.
