A focused marketplace of browser tools for Amazon FBA sellers, product researchers and brand teams. We just shipped our first extension — Amazon Reviews Exporter — and a new one lands every quarter. Every tool is built in-house, runs in your own browser session, and ships with a free tier.
Pull any ASIN's reviews across all 17 Amazon marketplaces into clean CSV or JSON. Filter by stars, verified status, keywords and date range — with every media URL preserved. Runs in your own browser session, no scraping proxies, no shared logins.
Daily organic rank snapshots for your ASIN-keyword pairs with competitor overlap and position history. Development at 62% — early access opens soon.
Real-time alerts when tracked competitors edit titles, bullets, images, price or A+ content. UX sketches in progress.
Best Sellers Rank, category position and revenue estimates live on every product page. Concept stage — scope under evaluation.
Get notified the moment a new extension lands, plus a launch discount on every Pro plan. One short email per tool, that’s the deal.
Every extension supports all 17 Amazon marketplaces from day one. No “US-only MVP”, no paid regional unlocks.
Tools run in your own browser session. No shared credentials, no scraping proxies, no background data collection.
Every extension ships with a free tier you can use indefinitely. Pro plans unlock limits — not core features.

Replaced a $149/mo scraping subscription with the Pro plan. Our review data finally opens cleanly in DuckDB on the first try.
Worked on amazon.co.jp with zero setup. Kanji survived the CSV. I don’t get to say that about a lot of tools.
Client voice-of-customer reports went from half a day to ten minutes. The adaptive rate-limiter is the unsung hero.
A slower, quieter method — BSR sanity checks, review-velocity filters, and the Q&A-mining trick no one is talking about. Written after auditing 340 sellers who outperformed a $299/mo research tool with free extensions.

Read article →A pragmatic setup that turns weekly exports into a queryable database — without hiring a data engineer.
Read article →Because we just launched. aSelex is a small studio — we ship one extension at a time and only when it’s actually good. Amazon Reviews Exporter is live today; the next tool is in active development. A new extension lands roughly every quarter.
Yes. No credit card, no trial countdown. The free plan exports up to 10 reviews per ASIN and you can use it indefinitely. Pro plans ($5.99–$9.99/mo depending on billing cadence) remove the cap and add advanced filters.
Never. Every tool in the marketplace runs inside your own logged-in browser session — no shared credentials, no server-side scraping. Your cookies, your rate limits, your privacy.
Chrome, Edge, Brave, Arc and any Chromium-based browser that accepts MV3 extensions. Firefox ports are on the roadmap for the second half of 2026.
Yes — we read every email. If what you need fits our principles (browser-side, free tier, 17 marketplaces) and the data is already visible to a logged-in user, it’s a candidate. Write us at support@aselex.app.
Install Amazon Reviews Exporter free, run it on your own ASINs, and judge the marketplace by the quality of that single extension. Everything else we ship will be built to the same standard.
