B+ PROTOCOL · PHASE 40

The price comparison
that travels with you.

B+ Sentinel watches the booking sites you visit and quietly reveals the sovereign-direct alternative — without a click, a redirect, or a single tracking pixel.

ADD TO CHROMEFREE · OPEN SOURCE · NO ACCOUNT REQUIRED

Coming to the Chrome Web Store. Until then, install in Developer Mode (instructions below).

01 · DETECT

Knows where you are.

When you open a hotel page on any major booking site, Sentinel quietly identifies the property and the room — locally, in your browser.

02 · COMPARE

Three prices, one glance.

See the sovereign BOTA Direct rate, the hotel's published direct rate, and the listing you're currently viewing. No tab-switching. No spreadsheets.

03 · VERIFY

The room you actually get.

If we have a match in our Honeycomb, we tell you whether it's The Exact Room™ — verified photos, dimensions, and view direction. Not a 'category sample.'

THE TRIAD

A discreet panel,
bottom-right of the page.

The Triad surfaces three prices and one verification badge. It never auto-expands, never demands your attention, never follows you to the next page.

Click View Offer to jump to the sovereign rate on BOTA, or Settle Direct to book through the hotel itself. Either way, the OTA's commission disappears.

THE EXACT ROOM™

Unlike OTA “sample” photos,
this is the room you check into.

When the Sentinel matches an OTA listing to a room in our Honeycomb that carries The Exact Room™ verification, you see it. Eight photos, declared dimensions, declared view direction, updated within the last twelve months. No category bait-and-switch.

Rooms with a video walkthrough or floor plan on file are upgraded to Platinum.

  3. 3Toggle Developer mode on (top-right corner of the page).
  4. 4Click Load unpacked and select the unzipped folder.
  5. 5The B+ Sentinel icon will appear in your toolbar. Visit any supported booking site and the Triad will surface bottom-right within a second of the page settling.

SUPPORTED SITES

The Sentinel runs only on hotel listing pages. It does not read, store, or touch anything else.

ZERO TRACKING

What we will never do.

  • ·Read cookies, login state, form inputs, or anything you type.
  • ·Track your browsing history across sites.
  • ·Build a profile of you. We don't even know who you are.
  • ·Persist scraped listing data anywhere beyond a transient comparison call.

The Sentinel sends only the public listing metadata it has just extracted — hotel name, room title, dates, prices — to our comparison endpoint, which uses it once to find a match and does not retain it as a session.
