Help & how-tos

Everything CarPeriscope does

We're on your side of the used-car table — save any car, watch the price and the seller's games, and get help closing the deal.

Getting started

  1. Add the extension. Install the CarPeriscope Collector from the Chrome Web Store.
  2. Save any car. On any listing — a marketplace, classifieds, or a dealer's own site — click the extension to save it to your watchlist.
  3. Track & decide. We keep the photos and details forever, watch the price and days-on-market, and flag drops, relists, and red flags. Open any car for comps, an AI take, and negotiation help.

Credits — how they work

A few of our services do real work behind the scenes (live web searches, reading your photos, pulling reports), so they run on credits. Everything else is free.

Your balance shows in the top bar of your watchlist — click Buy credits there to top up.

The services

📌

Watchlist & tracking free

Save any car and we track its price and days-on-market over time, catch relisting games and slow price drops, and alert you in-app (email on Co-pilot).

🧠

AI listing scan free

Turns a messy listing into clean facts — specs, options, the seller's claims, and a scam/red-flag check — the moment you save it.

🔭

Recon — web VIN search 10 credits

Searches the whole web for this car's VIN and saves every place it appears — dealer sites, classifieds, auctions, archives — so you catch cross-site relists and price games. Needs a VIN on the car.

👁

Vision — photo inspection 5 credits

Reads the listing photos and reports what it sees: the odometer off the dash, visible damage, aftermarket mods, cleanliness, and any window-sticker details. Verify in person — it's a read of the photos.

Deep Dive — full deal report 15 credits

One button runs region, photo inspection, web recon & comps and writes a shareable buyer's report — verdict, price read, watch-outs, questions to ask, and a suggested offer with your walk-away number.

🗺

Region — rust & climate free

From the car's location: road-salt/rust-belt exposure, coastal salt-air, flood and hail risk — plus exactly what to inspect for each.

📊

Comps & fair value Co-pilot

Comparable listings nationwide and a fair-value read, so you know whether the price is a deal or a reach.

📄

Full VIN history 15 credits

Title brands, accidents, salvage, odometer records and liens — the deep report before you commit.

💬

AI co-pilot Co-pilot

Talk through any car, get an AI take, a suggested offer with your walk-away number, and drafted messages to the seller — you send them.

Questions

Do credits expire?
Purchased credits never expire. Co-pilot's 60 monthly credits reset at the start of each month.
What if a car doesn't have a VIN?
Recon and full VIN history need one — add the VIN on the car's page (private-party listings often omit it). Everything else still works.
Is the AI always right?
No — Vision reads photos and the seller's claims are unverified. Use them as a head start, then confirm in person and with a history report.
What does it cost to start?
Nothing. The extension, watchlist, tracking, alerts, the AI scan, and Region are free. Upgrade only when you're serious about a car.
