Quiet software
for Amazon sellers. our first extension ships today

aSelex is a small studio building browser extensions for Amazon sellers, researchers, and brand teams. No scraping infrastructure, no shared credentials — just tools that run inside your own browser session and turn messy Amazon pages into clean, typed data.

01 / Our first extension

Amazon Reviews Exporter, the flagship release.

Built for the dull parts of review research. Fewer ceremonies, fewer settings, fewer browser tabs. The extension collects what Amazon already shows you — cleaner, faster, and in formats your tools actually want.

F/01
All 17 Amazon marketplaces
US, UK, DE, FR, IT, ES, JP, IN, CA, MX, BR, AU, NL, PL, SE, TR, SG — covered the day you install.
F/02
Precise filtering
Star rating, verified purchase, review media, date range, reviewer type, keywords. Applied before the export.
F/03
Typed CSV & JSON
One click to a clean file for Excel, Sheets, DuckDB, or a notebook. Column order and selection are yours.
F/04
Full media URLs
Every image and video URL is preserved, not just the review body. Useful for computer-vision workflows.
F/05
Batch ASIN queue
Paste a list or import a CSV/TXT/JSON of ASINs. The queue parses them sequentially with progress indicators.
F/06
Adaptive rate‑limiter
Slows down on anomalies, speeds back up when things are calm. You stay inside reasonable request budgets automatically.
02 / Workflow

Four steps, nothing else.

Install, queue, start, export. No accounts in the extension itself, no API keys to manage.

Step 01

Install from the Web Store

One click. The extension lives in your browser — no desktop app to maintain.

Step 02

Drop in your ASINs

Paste a list, import a file, or use the current product page. Each ASIN gets its own filter snapshot.

Step 03

Press Start.

Reviews stream in row by row with a live progress bar. Pause and resume any time — state persists.

Step 04

Export or copy

CSV, JSON, or straight to clipboard. Drop it into your spreadsheet or notebook and keep moving.

03 / How we build

What aSelex stands for.

Principles that shape every extension we ship. A short list, because we think short lists are harder to write than long ones.

P/01
Browser‑side, always
No scraping proxies, no headless servers, no shared logins. Our extensions run inside your own browser session — your cookies, your rate limits, your privacy.
P/02
Respect the source
Adaptive rate-limiters, honest timeouts, no hidden retries. We ship tools that behave the way a thoughtful human would when clicking through a site manually.
P/03
Data you actually use
Clean types, documented columns, boring predictable formats. CSV and JSON that open in Excel, Sheets, DuckDB, or a Python notebook without a single transformation step.

05 / Frequently asked

Questions, answered honestly.

The short answers first. If something’s missing, send us an email — we usually reply the same day.

Q/01 Do I need a seller account to use Amazon Reviews Exporter? +

No. Any regular logged-in Amazon shopper account works. The extension reads the same review pages that are already visible to you.

Q/02 How many reviews can I export? +

Free plan: up to 10 reviews per export. Pro plans remove that cap and let you pull whatever Amazon exposes for a given product — typically several hundred per ASIN, depending on Amazon’s current pagination behavior.

Q/03 Is this allowed under marketplace terms? +

Our extensions only access data that is publicly visible to any logged-in user. They do not bypass authentication, defeat protection measures, or collect private information. Use remains subject to each marketplace’s own terms and your local laws.

Q/04 What about payments and invoices? +

Paddle.com Market Ltd handles all billing as our Merchant of Record. Cards, local payment methods, invoices, VAT, refunds — all in one place. Your payment details never touch our servers.

Q/05 Can I cancel any time? +

Yes. One click in the Paddle customer portal. You keep Pro access until the end of the current billing period.

Q/06 Will there be more extensions under aSelex? +

Yes. The roadmap above is the honest picture: one extension shipped, several more in the works — all focused on Amazon seller workflows. Each is evaluated on its own; aSelex is the studio name, not a bundle. A single subscription today covers only the extension it was purchased for.

Q/07 Do you offer refunds? +

EU/UK customers have a statutory 14-day right of withdrawal. Elsewhere we offer a 7-day goodwill refund. Full details on the Refund Policy page.
