How is ZenGraph different from Keepa?
ZenGraph gives you Amazon price and sales rank history as part of your AsinZen subscription, right next to the tools you already use to decide what to buy.
Included at no extra cost
ZenGraph comes with AZInsight Advanced. No separate subscription for price history: one plan covers your research tools and your charts.
One view, every decision
See price history alongside AZInsight's profit calculator, hazmat and restrictions checker and stock checker, on the same Amazon page. No switching between extensions.
More than a price chart
Beyond price and rank history, ZenGraph shows every current offer with its own price and stock history, Buy Box stats by seller and a competitive summary, all in tabs on the same panel.
No credit card required. Cancel anytime.

On its own page, for any ASIN

Category rank and offer counts
Follow rank in the root and sub-category, plus how many New, FBA, FBM and Used sellers were on the listing, and how fast ratings are growing.
Offers
See every current seller on a listing with their own price and stock history, and filter them by condition, shipping and fulfillment.
Product details and averages
Identifiers, dimensions, categories, referral fee and parent ASIN, next to current, 30, 90 and 180-day averages, lows, highs and sales rank drops.
Buy Box stats
See which sellers won the Buy Box, their share of the time and when they last held it, for New and Used offers. Know if Amazon dominates before you compete.
Competitive summary
Reference prices, featured buying options, lowest priced offers and similar ASINs you can open with one click.

All prices, one chart:
Buy Box, Amazon, New, FBA, FBM, Used and Warehouse prices plotted together against sales rank, from 1 day to the product’s full history.
Category and offer graphs
Follow rank in the root and sub-category, how many sellers joined or left the listing, and how fast ratings are growing.
Product Details & Averages
Every key data point and its averages, side by side.
Complete product data
Identifiers, dimensions, weight, categories, parent ASIN, referral fee and launch date in one table.
Current vs. average

Offers
Every seller on the listing, with the history behind each offer.
Price and stock history per offer
Each offer shows its own price and stock chart, so you can tell which sellers keep inventory, which ones run out, and who keeps changing their price. Turn on historical offers to include sellers who already left the listing.
Filter the competition your way
Narrow offers by condition (New, Like New, Very Good, Good, Acceptable), by Prime, free shipping, FBA or FBM, and see totals by type at a glance. Seller name, rating and review count are listed for every offer.
Export to CSV or Excel

Decide with the full picture, not today's snapshot
A single price or rank tells you very little. ZenGraph shows the pattern behind it.
Is it actually selling?
Count sales rank drops over 30, 90 and 180 days instead of guessing from one number.
Is this price normal?
Compare the current price with its averages, lows and highs before you set expectations.
Can I win the Buy Box?
See how often Amazon or other sellers held it, and for how long.
Is competition growing?
Watch offer counts rise or fall, so you are not the tenth seller joining a crowded listing.
