AI product read

Expands Tumblr blog layouts to full-screen/wide mode for better content visibility

Tumblr's default layout restricts blog width, limiting the amount of content visible at once. This extension removes those width constraints to show more images and content simultaneously.

User installs extension -> Extension injects content_scripts (script.js and styles.min.css) into www.tumblr.com pages -> CSS removes width constraints and hides unnecessary UI elements -> JS observes DOM mutations to apply styles to dynamically loaded iframes and dashboard posts -> User sees expanded, wider Tumblr blog layout

Target users: Tumblr users who want to view more content per screen / Users who prefer wider layouts for image-heavy blogs / Power Tumblr users browsing many posts

The extension only modifies CSS and observes DOM on Tumblr pages; it does not interact with Tumblr's API directly. Analysis is based on static code review only. The actual behavior depends on Tumblr's current DOM structure, which may change over time and break the extension's selectors (e.g., .O4V_R, .j8ha0, ._6u2I are likely obfuscated or frequently changing class names).
No runtime testing was performed, so the extension's actual effectiveness on current Tumblr pages cannot be fully verified.
The extension has very few users (365) and reviews (10), which may indicate limited adoption or niche use case.

Monetization

No paid features detected

The extension is entirely free with no paid features, subscriptions, or billing logic. The keyword 'pro' found in _metadata/verified_contents.json is part of Chrome Web Store's file integrity verification metadata (treehash per file), not a paid feature indicator. There are no references to Stripe, PayPal, subscription, premium, upgrade, or any payment platform in the source code.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension itself does not implement any login mechanism. It is a content script that applies CSS/JS to www.tumblr.com. While Tumblr (the destination service) generally requires login to view blogs or use the dashboard, the extension does not gate its functionality behind a login, nor does it provide its own authentication. The extension works on any Tumblr page it matches, assuming the user is already viewing the page (which may or may not require Tumblr login depending on the specific Tumblr page's privacy settings).
