For eBay & Amazon sellers
Untangle the research,
so selling stays simple.
A browser extension that reads seller and buyer history for you, filters the listings you don't want to see, and gives you a plain read on risk — no verdicts, just the facts you'd have dug up yourself.
No spam — one email, when it's actually ready.
What it untangles
Four things that used to mean ten browser tabs.
Seller research, on the page
Hover a search result or open a seller's page and get feedback history, tenure, and a plain-language risk read — without leaving the listing.
Buyer history, before you ship
Look up a buyer's feedback pattern before you commit to a sale. Descriptive, not a verdict — you decide what it means.
Hide what you don't want to see
Keyword filters for search results on both eBay and Amazon — separate lists per platform, so hiding one doesn't hide the other.
A second look at review patterns
On Amazon, a structural scan flags star-distribution skew, verified-purchase ratio, and unusual review timing — context, not an accusation.
How it works
Install it, then forget it's there until you need it.
Add it to your browser
Untangle sits quietly on eBay and Amazon. It only does anything when you ask it to.
Hover, click, or scan
Research a seller, look up a buyer, or filter a search — each is one click from where you already are.
Get a plain read
Facts and a risk read, not a yes/no verdict. You're still the one making the call.

Worth knowing
What it reads, and what it doesn't.
Only eBay & Amazon pages
Untangle only reads the page you're already looking at, on ebay.com or amazon.com — nothing runs in the background on other sites.
Built to describe, not judge
Risk reads are plain-language summaries of public feedback data — never a fabricated reason, never a fraud accusation.
Your key, your data, if you want
Bring your own Anthropic API key and that call never touches our cost or our logs — it's yours end to end.
Real support. No phone tree.
No call center, no hold music, no "your call may be recorded." Submit a ticket and you'll hear back from the person who actually wrote the code.
Why this exists
Untangle started as a tool for one seller's own research — checking a buyer's history before shipping, sorting out which sellers were actually worth a second look, filtering out listings that didn't matter. It's built and maintained by one person, which means support replies come from someone who actually understands the question, but it also means features ship when they're ready, not on a roadmap built for a boardroom.
