Compare two products
without leaving Amazon.
The Ask Versa extension lets you stage one product, open the next, and get an AI side-by-side verdict — straight from the product page. No copy-pasting links.
Works with Chromium browsers (Chrome, Edge, Brave) and Firefox.
Compare from any page
Stage one Amazon product, open the next, and get an AI verdict — without copy-pasting links.

Same engine as the site — analyzes 200+ reviews and every spec for an honest verdict.
Live on the Chrome Web Store
One click from the official listing — no developer mode, no build files, no unpacked folder. Works in Chrome, Edge, Brave, and other Chromium browsers.

Read the badge, set your preference
What the toolbar badge means
AI is running in the background.
Verdict ready and result page opened.
Something failed — check the popup.
One product is waiting for its pair.
The “Open result page after compare” switch
A loading page opens the moment you compare and self-redirects to the full report when the AI finishes. You watch it work the whole time. No notification.
Nothing opens while it runs. When the AI finishes, the cached result page opens and a “Comparison complete ✅” notification fires — click it to reopen the verdict.
Common questions
Is the extension free?
Yes. It uses the same free daily allowance as the website — two fresh comparisons per day per visitor.
Does it work on Firefox or Edge?
Edge, Brave, and other Chromium browsers install it straight from the Chrome Web Store listing. Firefox can load the same package via about:debugging or AMO.
Where does my data go?
Only the two product URLs (resolved to ASINs) are sent to asversa.com. The extension stores a per-install UUID so it doesn't share the anonymous rate-limit bucket. No browsing history is collected.
Why didn't a comparison open?
If the “open after result” mode is on, nothing opens until the AI finishes — watch the badge. A ✓ means it's ready and the result tab has opened.
The context-menu labels changed — what do they mean?
“Add to compare” stages the product you right-clicked. “Compare with …” appears once something is staged and runs the AI verdict against the staged product.
Prefer the web version?
No extension needed — paste two Amazon links and get the same AI verdict right in your browser.
