On-device price tracking & deal reasoning
CartIQ — Price tracking that never gets tired of checking
CartIQ watches the prices you actually care about, continuously, and reasons about whether today's price is genuinely good — grounded in that item's own history, not a generic percent-off badge. Background checks run on a schedule even when your browser is closed, and a wishlist you build once follows you to every device.
Watches prices on items you’re tracking and reasons about whether a deal is worth taking.
Running locally means inference is free and unmetered — CartIQ can reason continuously instead of rationing AI calls the way a cloud service must.
Who it's for
The kinds of moments CartIQ was actually built around.
Deal-conscious online shoppers
Tracking a wishlist across sites and getting a straight answer on whether today's price is actually good, not just a generic percent-off badge.
Gift shoppers planning ahead
Watching a specific item’s price ahead of a birthday or holiday without having to check it manually every day.
Big-ticket purchase researchers
Waiting out the right price on electronics, appliances, or furniture — items worth tracking for weeks, not minutes.
Resellers & bargain hunters
Catching statistically meaningful price drops fast, across dozens of tracked items at once, instead of refreshing tabs.
Features
What CartIQ actually does, in depth.
Track any product in one click
"Track this" on a product page (or right-click a link) captures title, image, price, and currency — no manual entry.
Local AI deal reasoning
Judges whether today's price is actually good, grounded only in that item's own recorded price history — never invented.
Scheduled background price checks
Re-checks each tracked item on a schedule — daily, every 6 hours, or hourly depending on tier — via structured page data, no AI cost involved.
Smart cross-site alternatives
Finds comparable products elsewhere and ranks them against the tracked item's own attributes.
Reasoned deal alerts
Badges the toolbar only when a drop is statistically meaningful — e.g. 10% under a 90-day average — not on every price tick.
Cross-device wishlist sync
Tracked items follow you to your other devices via your account — the one thing this suite deliberately syncs.

Frequently asked
Questions specific to CartIQ. See the catalog-wide FAQ for account and billing basics.
Does CartIQ keep tracking prices when my browser is closed?
Yes. Background price checks run on a schedule server-side (daily to hourly depending on tier) using structured page data — no AI call needed for that step. Deal reasoning itself still runs on-device.
How does CartIQ decide a deal is worth an alert?
On-device AI judges the drop against that specific item's own recorded price history — for example, meaningfully below its 90-day average — rather than alerting on every small price change.
Is my wishlist private?
Your tracked items and price history sync to your account so they follow you across devices — the only content this suite syncs by design, since a wishlist is only useful if it travels with you.
What's the difference between Plus and Pro?
Plus checks prices every 6 hours with 150 smart searches/month; Pro checks hourly with 250 smart searches/month. Both include unlimited tracked items and unlimited price-history reasoning.

A note on accuracy: CartIQ runs its AI reasoning on-device — nothing is sent to a server to get an answer. On-device AI is not guaranteed to be accurate, complete, or even correct — summaries, deal judgments, extracted information, substitution suggestions, memos, and detections can be wrong, incomplete, or missed entirely. Treat every AI-generated result as a starting point, not a final answer, and verify anything sensitive, financial, medical, legal, or otherwise high-stakes yourself before acting on it.
