Markout · Install guide

Install Markout in 30 seconds.

For private alpha testers · Chrome / Edge / Brave / Arc

Heads up: Markout is in private alpha. Until we ship to the Chrome Web Store, you'll install it as an "unpacked" extension — exactly the same flow your developers use. Takes one minute. Auto-updates won't trigger; new versions get a new zip.

Download the package

Download the Markout extension, then unzip it. You'll end up with a folder called extension/. Put it somewhere you won't accidentally delete (your Documents folder is fine — not Downloads, since those get cleaned out).

Download Markout extension ↓

Open Chrome extensions

In Chrome, type chrome://extensions in the URL bar and hit return. Or click the puzzle-piece icon in the top right, then "Manage Extensions" at the bottom.

Enable Developer Mode

Top-right of the extensions page — flip the "Developer mode" toggle on. Three new buttons appear: Load unpacked, Pack extension, Update.

Load Markout

Click "Load unpacked." Navigate to the folder you unzipped in step 1 and select markout-extension/. Markout appears in the list. The toolbar gets a new amber dot.

Pin it to the toolbar

Click the puzzle-piece icon, find Markout, click the pin. The amber dot is now permanent in your toolbar — clicking it opens the popup with your tracked listings and recent changes.

Turn on email alerts (recommended)

Open the popup → "Settings" link in the footer. Enable cloud sync, paste your email, save. From now on you'll get a daily digest of every tracked listing that changed.

Start tracking

Open Crexi or LoopNet like you normally would. Browse a listing. That listing is now tracked. Open it again in a day, a week, a month — Markout will tell you everything that changed.

What to expect in week one

Day 1. Three sample listings appear in your feed so the UI doesn't look empty. They disappear the first time you open a real Crexi/LoopNet listing.
Day 2-3. First real changes start showing up — usually status flips and price drops on listings you've opened twice.
Day 5-7. The pipeline view (footer link) starts being useful — sort by last-changed and you see a real-time pulse of your watch list.
Week 2. Email digest is doing the work for you. You stop manually clicking through your spreadsheet.

Common questions

"Will this break Crexi?" No. Markout reads the DOM passively. It doesn't modify pages.

"Does it work in incognito?" Only if you specifically allow it in chrome://extensions. Off by default.

"What if I share a machine with someone?" Each Chrome profile gets its own install ID and its own data. There's no leakage across profiles.

"How do I uninstall?" Three-dot menu next to Markout in chrome://extensions → "Remove from Chrome." All local data is wiped. Your install ID is still in the backend but no longer tied to anything.

"Will it auto-update?" Not yet — that requires Chrome Web Store. While we're in alpha, we'll email you each new zip.

If something breaks

Email [email protected] with: a screenshot of what you're seeing, the URL of the listing page (if relevant), and your Markout install ID (visible in the popup footer). We turn around fixes inside 24h during alpha.
