Read the evidence
Current-page reviews, 1–3 star review pages, Amazon’s “Customers say” summary, and a manual paste/CSV fallback.
Free · local · no account
Find the buyer objections your Amazon listing never answers.
ListingGap reads the reviews a buyer already sees, clusters the recurring complaints, checks whether your title and bullets answer them, and writes a paste-ready rewrite — without uploading your listing or inventing facts.

One job, done deeply
From buyer language to listing copy.

45 objection aspects with negation-aware matching. Every gap shows what buyers say and what your copy says.
Write the page
A title within the marketplace limit, five bullets, an A+ outline, and quick wins — each tied to evidence.
Why it stays free
The analysis engine ships with the extension.
There is no server to pay for, no AI API to meter, and no account to manage. That means no credits, no trial, no license key, and no paywall. The trade-off is deliberately narrow scope: ListingGap does not estimate sales, pull keyword volume, automate PPC, or generate images.
No data uploadReview-page requests go only to the Amazon domain you are already visiting.
No remote codeEvery line of analysis code is packaged with the extension.
No invented factsMissing materials, tests, and certifications are marked as needing input.
No lock-inCopy blocks, export Markdown or CSV, and clear local history at any time.
Privacy
Your listing stays in your browser.
ListingGap has no backend, analytics, telemetry, advertising, account, or remote AI. Listing and review
text is processed in the side panel. Up to 20 audits and your settings are stored with
chrome.storage.local on your device.
Support
Something not extracting?
Amazon changes its pages often. If a listing does not extract, refresh the product page and try again. If Amazon hides low-star review bodies, use the paste/CSV fallback. For bugs, feature requests, or privacy questions, open an issue.
