Browsertrail
BrowsertrailNew

You read it last week. Chrome cannot find it. Browsertrail can.

Chrome only remembers page titles. Browsertrail remembers the words that were on the page, across your open tabs, closed tabs, bookmarks and history, so the thing you half-read on Tuesday is one search away. Private and local: your browsing never leaves your device.

Chrome searches titles. You remember words.

Run the same search against a small sample memory. The left side is what Chrome's history page can see. The right side is what Browsertrail kept.

Try:

Chrome history search

Matches page titles and URLs only

No history entries match. The words were on the page, not in its title.

Browsertrail

Matches the text of the page, ranked by how you actually used it

A small sample memory of 9 pages so you can feel the difference. Locked rows are how Free shows anything older than 7 days: still found, still ranked, never blurred, one click from unlocking.

What it remembers, and when it starts

Tabs and bookmarks are searchable the moment you install. The two things that make the memory deep, your existing history and the text of the pages you read, are separate permissions you grant from the onboarding tab when you are ready. Decline both and it still works.

Incognito is never recorded, whatever you have allowed.

SourceWhat is rememberedPermission
Open tabsThe moment you installEvery tab in every window, updated as you open, switch and close themNone extra
Closed tabsThe moment you installIts own log of what you closed, kept after Chrome restarts and forgets its own listNone extra
BookmarksThe moment you installTitle, URL and the full folder path, so folder names work as search termsNone extra
Chrome historyWhen you allow itThe last 90 days of pages you have already visited, imported in the backgroundHistory, asked once during onboarding
Page textWhen you allow it, per site or everywhereThe readable text of pages you visit, up to about 3,000 words each. Banking, payment, login and password-manager pages are skippedRead page content, per site or all sites

What is in it

All of it is in Free. Pro only changes how far back the memory reaches.

Full Text History Search

Find pages by the words that were on them, not just their titles - the thing Chrome history search cannot do

Tab Search

Jump to any open tab in any window instantly, and search tabs you just closed even after Chrome forgets them

Bookmark Search

Find bookmarks by title, URL, folder path or the text of the page itself

Chrome History Import

Optionally import and search the last 120 days of your existing Chrome history, so the memory is useful on day one

Command Palette

A spotlight-style popup that searches from the first keystroke on any page

Side Panel & Omnibox

A full side panel for longer sessions, and address-bar search with the "bk" keyword that needs no extra permissions

Advanced Search

Exact phrases, excluded words, limit to one site, restrict to titles or content, and filter by when you saw it

Engagement-Aware Ranking

Results weighted by relevance, recency, how often you return and how long you actually spent reading - not just keyword overlap

Unlimited Memory

Free remembers the last 7 days. Pro remembers everything - and the memory you built while on Free unlocks instantly

Privacy Center

Exclude sites, forget a domain and everything stored about it, pause memory, or wipe it all - in one place

Export & Restore

Your data is always yours - export the whole memory as JSON any time, free, and restore it on another machine

Your Browsing Data Stays On Your Machine

The index is built and stored locally and no page, URL or search term is ever uploaded - the extension only contacts Syntaximos to activate your account, check your plan, and send feedback you choose to submit

Built for hands that stay on the keyboard

Search opens from anywhere, results arrive as you type, and you never have to reach for the mouse to get back to a page. Typos are forgiven and prefixes match, so the first few letters are usually enough.

Open it

  • Open the search palette on any pageCtrlShiftK
  • Open the side panelCtrlShiftY
  • Search from the address barbkSpace

Cmd instead of Ctrl on a Mac. Every shortcut can be changed in chrome://extensions/shortcuts.

Narrow it down

    Only open tabs. Also is:closed and is:bookmark

  • in:title

    Match titles only. in:content for page text only

  • after:last week

All of these are also available as a form in the side panel if you would rather not remember the syntax.

A record of everything you read is only acceptable if nobody else can read it

So it is not a promise in a policy. It is how the extension is built.

It cannot talk to the internet
The extension's own content security policy forbids network requests, and the release build fails if one slips in. There is no server for your browsing to reach.
Sensitive pages are skipped before capture
Banking, payments, webmail, password managers, login, checkout and anything on localhost are on a built-in skip list. You can add any site to it.
Forget is one keystroke
Forgetting a site removes every page and visit from it and stops remembering it. Pause stops everything, with a badge on the toolbar so you can see it is paused.
It leaves when you do
Export the whole memory as JSON any time, on Free or Pro, and restore it on another machine. Delete everything with one button.
The account holds nothing about your browsing
A free Syntaximos account activates the extension and carries a Pro licence between machines. It never sees a page, a URL or a search.
Old visits age out on their own
Page text is kept for 180 days by default and visits for a year. Both are adjustable, including forever.

Free remembers this week. Pro remembers everything.

There is no trial clock and no stripped-down tier. Free is the whole product with a seven-day memory. Pro is the same product with no limit on how far back you can look.

  1. Day 1

    Useful before lunch

    Open tabs and bookmarks are searchable the moment you install. Allow history and the last 120 days import in the background.

  2. Days 1 to 7

    Everything you read is kept

    Every page you visit is indexed in full, with the words that were on it. Free searches all of it. Nothing is sampled or held back.

  3. Day 8

    The first lock

    A result older than 7 days is still found and still ranked. It shows its title, site and date with a padlock. You always know what you are missing.

  4. Upgrade

    It all comes back

    Browsertrail never stopped indexing. Pro removes the time filter, so every page you saw while on Free unlocks at once.
