AI product read

Bridge extension that enables electronic applications (e-Gov) using My Number Card through the freee company establishment service

Allows freee users to use their My Number Card for electronic government applications (company establishment filings) by relaying authentication and signing requests between the freee web app and a native My Number Portal application

User logs into freee会社設立 on k.secure.freee.co.jp → the extension injects content.js which signals its presence → freee web app dispatches MynaPortalAuth/MynaPortalSign custom DOM events → content.js catches these events and sends them via chrome.runtime.sendMessage to background.js → background.js forwards the message to the native app jp.co.freee.myna via sendNativeMessage → the native app communicates with the My Number Card reader and returns the response → response flows back through the chain as MynaPortalAuthFinish/MynaPortalSignFinish events

Target users: Japanese entrepreneurs establishing companies through freee会社設立 / Users of freee's electronic application services who need My Number Card integration / Japanese business users performing e-Gov electronic filings

Cannot verify the native app (jp.co.freee.myna) behavior or its own login/payment requirements
Cannot confirm whether freee会社設立 specifically requires a paid freee plan to access this functionality
The extension is extremely minimal (only ~29 lines of meaningful code) so there is little ambiguity in the analysis

Monetization

No paid features detected

No payment, subscription, billing, premium, or upgrade references found in the source code. The extension is a simple message relay bridge with no gated features. While freee as a service has paid business plans, the extension itself does not implement any payment logic or feature gating.

Confidence: 85
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension operates exclusively on k.secure.freee.co.jp (the authenticated section of freee's service) and bridges authentication/signing events (MynaPortalAuth, MynaPortalSign) between the freee web app and a native My Number Card application. To use the core workflow (electronic application via My Number Card for company establishment), users must be logged into their freee account.
