Helps Naver blog operators improve their search engine optimization (SEO) by analyzing Naver search results, blog content, and keyword data, enabling them to create more discoverable content

User navigates to Naver search or blog pages → extension content scripts inject analysis UI → user triggers analysis → extension scrapes search results/blog content → sends data to api.reviewerns.com for SEO analysis → results displayed in-page. Blog editor addon provides character count and Word export. Blog posts can be backed up locally via IndexedDB.

Target users: Naver blog operators / Korean content creators focused on SEO / Digital marketers using Naver platform

The api.reviewerns.com server may enforce authentication or paid tiers server-side that are not visible in the extension code
The reviewerns.com portal link may require an account but this is external to the extension's core workflow
blog_editor_addon.js is very large (376KB, minified) and may contain unexamined features due to size

Monetization

No paid features detected

No billing, subscription, payment, premium, plan, Stripe, or upgrade UI/logic found in the extension source code. All 'upgrade' matches are IndexedDB's onupgradeneeded (not product upgrades). All 'pro' matches are from library file paths (e.g., Font Awesome Pro comment in SVG). The extension sends analysis requests to Reviewerns API without any gating, feature flags, or payment checks. The destination service (reviewerns.com) may have its own paid tiers, but the extension itself does not gate features or prompt for payment.

Confidence: 85
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension source code contains no login UI, no authentication tokens/cookies/credentials, no account creation flow, and no authorization headers in API calls. The extension sends unauthenticated POST requests to https://api.reviewerns.com/nsupporter for analysis. While the popup links to https://www.reviewerns.com/portal/ (which may require an account on the website), this link is optional and not needed for the extension's core workflow of analyzing Naver search/blog content.
