Research Amazon Merch niches with BSR, dates, ASINs, filters, scans, and exports. Your Amazon research data stays on your device. iScaleMerch is a local-first research workspace for Amazon Merch on Demand sellers. It adds useful product data to supported Amazon pages, scans keyword niches, queues research, and exports CSV files without sending your research to an iScaleLabs server. Main features: - Product overlays for BSR, date first available, ASIN, brand, price, ratings, and review counts. - Keyword scanning across Amazon search results, including queued scans and a saved Workspace. - Niche Finder phrase research powered by Amazon suggestions and result counts. - Filters for Merch products, licensed brands, sponsored listings, BSR, dates, and relevance. - A local CSV catalog, automatic CSV exports, CSV import, and a reusable local CSV library. - Support for Amazon marketplaces in the United States, United Kingdom, Germany, France, Italy, Spain, and Japan. Privacy and data disclosure: iScaleMerch reads Amazon page content and related Amazon browsing activity only to provide the visible research features above. Scan results, browsing rows, settings, imported CSVs, and saved workspaces are stored locally in Chrome on your device. They are not sent to iScaleLabs. There are no iScaleLabs accounts, analytics, telemetry, advertising, or tracking servers. If you deliberately click Ask GPT or Phrase Investigator, the selected research text is submitted to OpenAI through your own ChatGPT account. That optional action never occurs automatically, and iScaleLabs does not receive the prompt or response. iScaleMerch is free to use. It is not affiliated with, endorsed by, or sponsored by Amazon, Google, or OpenAI.
