Finally, an extension that lets me view AND edit markdown files directly in Chrome! The split view with real-time preview is amazing. Mermaid diagrams work flawlessly. Highly recommended for developers!

AI product read

Markdown document viewer and editor in the browser

Allows users to view and edit Markdown files (.md, .mdx, .mkd, .markdown) directly in Chrome without needing external applications or services

User installs extension -> navigates to a Markdown file (local or remote) or opens one via file:// -> extension automatically injects content script -> user can switch between Editor, Split, and Viewer modes using toolbar buttons or keyboard shortcuts -> settings persisted in chrome.storage.local

Target users: Developers / Technical writers / Documentation authors / Anyone who writes or reads Markdown files

The js/content.js file is very large (~4.8MB) and minified/bundled, making it difficult to fully trace all code paths for potential hidden features. However, grep searches for login/payment keywords returned no results in any source file.
The extension references ssem.ai in the uninstall URL and background script, but no actual network requests to this domain were found in the code for authentication or licensing purposes.
Static analysis detected 'upgrade' keyword but investigation confirmed it was from MDC CSS class names, not actual upgrade functionality.

Monetization

No paid features detected

The extension is a free Markdown viewer/editor with no paywalls, subscription prompts, or feature gating. The 'upgrade' keyword detected in static analysis was a false positive from MDC (Material Design Components) ripple-upgraded CSS classes, not actual upgrade/payment functionality. No Stripe, PayPal, or other payment platforms are referenced. The extension provides all features (editor, split, viewer modes, themes, shortcuts) without restriction.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally within the browser. It uses chrome.storage.local for settings and content scripts to inject into markdown files. There is no authentication flow, no API calls requiring credentials, and no redirect to a login page. The extension works with file://, http://, and https:// URLs without requiring any account.
