In seconds, see why buyers pick your competitor — not you.
Paste one ASIN. SynthX AI auto-pulls your real competitors, runs a full synthetic buyer panel, and hands back a scored teardown and a ready-to-publish listing — in seconds, with zero setup.
Audit it. Test it. Track it.
Three jobs, one loop: diagnose why a listing is losing, prove the better version wins before you publish, then watch it compound as competitors move.
Audit
Why you're losing the clickPaste one ASIN. A category-true buyer panel scores your listing against your real rivals and pinpoints the gaps costing you the sale.
Losing on size clarity & trust badges.
Test
Prove the fix wins firstPut your change on the real shelf against your actual rivals. See your share of shoppers, why they still pick a competitor, and a rewrite that's re-tested until it wins.
A leads on a clearer size story.
Track
Monitoring on autopilotRe-audit every listing on autopilot and get alerted the moment it matters — your Win Probability shifts, or a rival drops their price, rewrites their listing, or launches a new coupon or offer.
Sample figures shown. Every number comes from the listing you paste.
We auto-pull your real competitors
Hero image, price, rating & review count — pulled from Amazon automatically. No manual uploads, no survey building.

Prove the fix wins — before you publish
We put your change on the real shelf against your actual competitors, show your share of shoppers, the reasons they still picked a rival, and hand back a rewrite that's re-tested until it wins.
Shelf pick-share, head-to-head
B winsSimulated across a category-true panel, with the shelf reshuffled each round. Raw counts and a confidence grade are shown — small gaps are called “too close to call.”
Why shoppers still chose a rival
- The rival's 2-pack reads as better value at a similar price.
- Their reviews shout “no leaks” — your proof is buried in bullet 5.
We only surface a rewrite after it's re-tested on the same panel and actually takes more shoppers than your current listing — never a guess.
Sample Pre-Test. Every run uses the listing and rivals you paste.
Why you can put the verdict in front of a client
It's a simulation — so we built it to earn the call. Every verdict is graded, order-bias controlled, honest about ties, and measured against what really happened after you published.
A confidence grade on every verdict
Low, medium or high — so your team knows when to act and when to dig deeper, never a naked number.
Order-bias controlled
We reshuffle the shelf every round and only call a winner when the result holds across every order.
No forced winners
Differences inside the panel’s noise are called “too close to call” — we never spin a tie into a win.
Backtested against reality
A self-checking agent loop validates each estimate, and we measure our verdicts against what actually happened after you publish.
Simulated shopper reactions are a directional signal — not real customer data or a sales forecast — shown with a confidence grade, not a guarantee.
Built for the decisions that cost you money
From winning the pitch to rescuing a listing that won't convert — see how agencies and brands put a category-true buyer panel to work.
The problem
Listings are graded on gut feel. Tools like PickFu need manual uploads, survey building and real money per poll — so agencies pitch “optimizations” they can't prove.
The fix
SynthX AI is a prescriptive, evaluative engine with zero setup. Paste an ASIN and it simulates how real category buyers judge your listing against rivals — turning “trust me” into a scored, evidence-backed teardown.
The only tool built to tell you why your listing is losing
Other tools check ifyour listing is complete. SynthX AI benchmarks it against the competitors you're losing to right now — and tells you exactly what to fix.
Helium 10 and Jungle Scout size the market. PickFu polls a room of strangers. SynthX AI tells you why the buyer picked them — not you.
And we don't stop at the audit. SynthX AI keeps watching the listing every week — Win Probability, listing health, price, rating & reviews, BSR rank, and competitor badges & offers — then pings you the moment something moves.
The numbers that build the case — and keep it
Every audit now opens with the money at stake, the risks moving against you, and the AI-search terms to win — each graded for confidence, then re-checked every week.
Profit left on the table
Every teardown opens with a modeled profit + TACoS forecast — what closing your win-probability gap is worth at your price and margin. A business case, not just a score.
Stockout radar
Live availability on you and your rivals — flagged when a stockout is bleeding your rank, and when a competitor goes out of stock and their demand is up for grabs.
Win the AI answer
The questions shoppers ask ChatGPT, Gemini, Perplexity and Rufus — with the exact claim your listing needs to win them — alongside SEO terms validated against real search volume.
Numbers you can defend
Every estimate runs a self-checking agent loop — propose, validate against measured data, refine — and ships with a confidence grade. Credible, not guessed.
Forecasts are modeled and AI-predicted, each shown with a confidence grade — a guide to what to fix, not a guarantee.

Read allReviews decide the peak-season click — and you can fix trust before more arrive

Amazon's fall Prime event rewards the listing that priced and prepped early. Read the shelf's deal posture, set a number you can defend, and fix what the deal traffic will land on — before the event, not during it.
