Allows teachers/users of the Benesse Mirai Seed educational platform to easily capture webpage screenshots and attach them to communication cards (Okurinku Plus) without manual screenshot-then-upload workflows.

1. User opens a card creation screen in Okurinku Plus (miraiseed-class.benesse.ne.jp) in a browser tab. 2. User navigates to any webpage they want to capture in another tab. 3. User clicks the extension popup button. 4. Extension captures the visible tab as a PNG screenshot, displays a preview. 5. User clicks '挿入する' (Insert) to send the screenshot, URL, and title to the Okurinku Plus card editor tab via content script message passing.

Target users: Teachers and educators using Benesse Mirai Seed (みらいシード) / Users of Okurinku Plus (オクリンクプラス) card communication platform

The extension is minimal (15 files, 18.29 KB) with straightforward message-passing logic; there is very little ambiguity.
Cannot confirm from source alone whether the destination service requires paid subscription vs. free school accounts.
The content script injects into miraiseed-class.benesse.ne.jp but the actual receiving logic on the web app side is not included in the extension package.

Monetization

No paid features detected

The extension contains zero payment processing code, no subscription checks, no premium/upgrade UI, and no billing API calls. All 'pro' keyword hits are false positives (Promise objects, CSS comment referencing precss.io/program). The extension is a simple screenshot capture-and-relay utility with no feature gating. The destination service (Benesse Mirai Seed) may have its own paid subscription model for schools, but the extension itself does not gate features behind payment.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension requires the user to have the Okurinku Plus (オクリンクプラス) card creation screen open on miraiseed-class.benesse.ne.jp. This Benesse educational platform requires authentication to access. The extension itself has no login UI but cannot function without the user being logged into the destination service. Error message in sendImg.js (line 45): 'オクリンクプラスでカード作成画面を開いている必要があります'.
