Daily diff on every ASIN that matters.
Track your brand, your hijackers, and your rivals across every marketplace — with daily snapshots, Buy Box ownership timelines, discount heatmaps, and a one-click AI summary that explains what changed and why.
One ASIN list. Three workflows for the price of one.
The same daily-diff loop you'd build with five tabs of price-tracker apps — except hijackers, coupons, and Buy Box flips all surface in the same inbox, scored and linked back to the source snapshot.
Add the ASINs you watch
Paste your brand ASINs and the competitors you care about. Daily / twice-daily / hourly per ASIN — credits stay capped to your daily budget.
We diff every snapshot, every day
Price, BSR, sellers, reviews, coupons, Buy Box ownership — compared to yesterday and to the last 30 days. Real changes become alerts. Noise stays out of the inbox.
Act before the day ends
One inbox, one AI summary per ASIN, one-click jumps to the snapshot. Mark read, dismiss, or send a digest to the team — every alert links to context, not just text.
One table, every ASIN, every signal that matters.
The morning view — your brand mixed with the competitors on the same canvas. Hijackers, stockouts, review surges, and price drops flagged inline so you scan once and act.
- Per-ASIN schedule (hourly / twice daily / daily / every 2 days / weekly).
- Inline pills for hijacker, stockout, review surge, coupon — color-coded.
- Owner vs. 3rd-party brand tags so you never mix up "my brand" with "compete".
Price dropped sharply from $89.99 to $74.98 over the last 6 days (-16.7%), with a -46% strikethrough discount activated on May 9. A new uninvited seller (RandomReseller Co.) appeared 2 hours ago undercutting your Buy Box at $72.50 — first hijack event in 47 days. Recommend acting on the hijacker quickly given the small review base.

Spot the pattern before your competitor does.
Twelve weeks of daily discount activity in one heatmap — see when each competitor leans on coupons, which days of the week they peak, and where the seasonal pressure builds.
- Daily discount % by weekday — darker cells mean deeper drops.
- Per-ASIN heatmaps so you compare patterns side-by-side.
- Auto-detected strongest discount windows (e.g. "Mon–Wed in weeks 5–6 / 11–12").
Control when fetches run and what they cost.
Set a preferred fetch hour in your timezone, cap daily credit spend, and pick a default schedule for new ASINs. Every cost shows up in plain numbers — no surprise overages.
- Preferred fetch hour anchors daily / every-2-day / weekly schedules.
- Daily credit cap with a live progress bar — set to unlimited if you trust the schedule.
- Default schedule for new ASINs — Hourly, Twice daily, Daily (recommended), Every 2 days, Weekly.

Talk to a humanWhich Amazon marketplaces does this support?
All 20 supported Amazon marketplaces — .com .ca .co.uk .de .fr .it .es .nl .com.be .ie .se .pl .com.tr .sa .ae .co.jp .com.au .sg .com.mx .com.br. Add ASINs from any of them in the same workspace.
How does the hijacker detection work?
Every snapshot compares the current seller list against the previous one and your trusted-seller allowlist. Any new uninvited seller on a brand-owned ASIN triggers a CRITICAL hijacker alert — usually within minutes of the next scheduled fetch.
Do credits roll over?
No. Credits reset at midnight in your workspace timezone. Set a Daily credit cap to keep spend bounded — oldest-due ASINs are fetched first when you hit the cap.
Can I get a daily email digest instead of inbox alerts?
Yes — the Digests tab sends a daily roll-up of new hijackers, biggest price drops, and Buy Box changes. Weekly is also supported. Per-ASIN webhook delivery is on the roadmap.
Is there an API?
Not yet for the public — the underlying snapshot pipeline is exposed to the Monirum browser extension, but a public REST API is on the post-beta roadmap.
