Simplifies Amazon product SEO research and Sponsored Product ad keyword selection by bulk-extracting autocomplete suggestions instead of manually typing each variation

1. User navigates to Amazon and enters a keyword in the search box. 2. Extension injects a 'キーワード抽出' (Keyword Extract) button into the search bar area. 3. On click, extension calls Amazon's completion API with the keyword, then recursively expands each suggestion up to ~200 keywords. 4. Results appear in a textarea panel that can be copied to clipboard. 5. Suggestion dropdown items also show real-time search result counts.

Target users: Amazon sellers / E-commerce product researchers / Amazon Sponsored Product advertisers / SEO professionals focused on Amazon marketplace

The PRO-only features (graph3, chukuhan) in master.js have empty linkTags suggesting they are vestigial placeholders from a related product (Shopping Researcher) rather than payable features of this extension
Cannot verify if the external store-can.appspot.com service requires paid subscription for its separate product features

Monetization

No paid features detected

The keyword extraction feature (the extension's core function) is completely free with no payment gating. Two stub entries in master.js (lines 24-25) reference 'PRO版のみ有効です' (PRO version only) for graph and direct-sales-price features, but these have empty linkTag values meaning they are disabled/inactive placeholders. A localization string references '有料版' (paid version) linking to an external product page (store-can.appspot.com/lp/shoppingResearcher#compare), which belongs to the separate 'Shopping Researcher' product by the same developer, not this keyword getter extension. No payment APIs, billing calls, or upgrade prompts exist in the source.

Confidence: 85
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension's core workflow (Amazon keyword suggestion extraction) requires no login or account. It calls Amazon's public completion API using session identifiers extracted from the Amazon page DOM (ue_sid, ue_id, ue_mid in main.js:51-53), not user credentials. No authentication flow, login UI, or account creation exists in the source code.
