Papercrane
Stop reading Keepa charts one ASIN at a time.
Keepa's chart is built to study one product. Papercrane reads price, sales rank, and deal alerts across your whole watch list at once and builds a live dashboard that tracks all of it together.

The parts of Keepa that don't scale past one product
One tab, times fifty.
Keepa's chart is the best price and rank history on Amazon, for one product at a time. A watch list of fifty competitors is fifty tabs, read one after another, with nothing that puts them side by side.
The quota wall.
The Pro plan's daily quota covers an estimated 36,000 ASINs and refills at 5% an hour once spent; scan a real catalog and you are waiting on tokens to trickle back before you can finish the list.
Price and rank, not your margin.
Every number Keepa shows is a list price. What a product would actually earn after referral fees, fulfillment, and storage lives in a different system entirely, and Keepa was never built to reach it.
Your whole watch list, one dashboard, not fifty tabs
Keepa's own handler can already read a hundred ASINs in a single call, it is the site's own interface that keeps them one chart apart. Papercrane reads your list at once and draws it as a live board: price, sales rank, buy box status, and the newest deal alert, side by side.
Watch list, this morning
| Product | Tag | Price (30 day) | Sales rank trend | Buy box | Last deal alert |
|---|---|---|---|---|---|
| Stainless steel water bottle, 32oz | Yours | $18.40 | #1,240 | You | none |
| Insulated bottle, 32oz, matte finish | Competitor | $16.90 | #890 | Them | 3 days ago, 14% off |
| Bamboo cutting board, 3 piece set | Competitor | $27.50 | #4,120 | Them | none |
| Silicone baking mat, 2 pack | Yours | $11.20 | #6,780 | Them | none |
| Ceramic coffee mug set, 4 pack | Competitor | $22.00 | #2,150 | Them | 2 days ago, 10% off |
| Reusable produce bags, set of 9 | Yours | $14.50 | #3,600 | You | none |
One conversation turns a list of ASINs into a dashboard like this, refreshed on the schedule you set. Connect a seller account too, and the same board can show which of these prices you could actually match.
Ask what fifty tabs used to answer
Which of my watched ASINs dropped price in the last seven days?
Show sales rank trend for my top twenty competitor ASINs, side by side.
Which products on my list just lost the buy box, and to whom?
Which of today's deal alerts are actually below the ninety day average price, and which are noise?
How does my product's rank compare to the three ASINs I'm sourcing against, over the last quarter?
Alert me the next time a competitor's price crosses below mine.
What would matching this competitor's price actually leave me, after my Amazon fees?
Every answer comes back as a chart on a live dashboard, not another browser tab.
Keepa doesn't know your fees. Your seller account does.
List price and kept money are two different numbers, and Keepa was never built to close that gap. Connect your Amazon Seller Central account too, and the same watch list dashboard can show whether a competitor's price is one you could actually afford to match, not just one you can see.
1. Connect Keepa
2. Ask about your watch list
3. The agent plans, queries, and builds a hosted dashboard
4. It stays live, and errors route back to the agent automatically
A key you create in your Keepa account settings, scoped to whatever tier you already pay for. Every call in this connection reads; none of them can change a price or a listing, because Keepa itself has nothing to write to.
Three ways to watch a list of products
| The job | Keepa's own site | Keepa plus your own spreadsheet | Keepa plus Papercrane |
|---|---|---|---|
| Study one product's history | One clear chart | Same | Same, as one tile among many |
| Compare twenty or more ASINs at once | One tab per product | Paste numbers out by hand, rebuild it monthly | Ask once, keep a live dashboard |
| Rank deal alerts against your own list | A flat list of deals | Cross reference by hand | One dashboard, ranked and refreshed |
| See what a price actually leaves you | Not shown, list price only | Add your fees and costs yourself | Joins Seller Central fee events, if connected joins Amazon Seller Central |
| Share with a partner or a client | Screenshot the chart | Email the spreadsheet | Send a link to a live dashboard |
| What it costs to look | Pro plan or token tier, both cost more as your list grows | Your evenings | Free to connect and ask; paid starts at publishing |
When you don't need us
If your workflow is scanning a barcode in a store aisle and getting an instant profit verdict before you buy, SellerAmp is built exactly for that, complete with eligibility and IP alerts, starting around twenty dollars a month. If you want keyword research, listing optimization, and advertising bundled with product data in one subscription, Helium 10 packages all of that; we don't do keywords or advertising management. Papercrane is worth paying for once you're already tracking a real watch list and want it as a live dashboard you can share, especially the moment it needs to sit next to your own sales and fees.
Questions sellers ask us
A watch list means more next to your own numbers. Most Keepa users connect their seller account for fees, and their ad account for what it costs to compete on the products they're watching.
Connect Keepa, hand it your watch list, and stop tabbing between fifty product pages to see what changed.
