AI product read

AI-powered browser assistant that provides text-based AI assistance on any webpage

Helps users quickly understand, summarize, translate, or improve text content while browsing without leaving the page

User selects text on any webpage → clicks floating Cortex icon or uses keyboard shortcut → chooses action (Summarize/Explain/Translate/Fix) or enters free-form question → AI processes request via OpenRouter API using user's configured API key → response displayed in floating panel with markdown formatting → user can continue conversation or start new one

Target users: Students researching and studying / Professionals reading reports and documents / Language learners needing translations / Writers wanting to improve text / General users wanting AI assistance while browsing

The extension is built with WXT framework and uses React, making some source code minified and harder to interpret. However, the key decision points (login, paid features, product function) were clearly identifiable from the options page, content script, and manifest. The pricing displayed is from OpenRouter's API and reflects external model costs, not extension-paid features.

Monetization

No paid features detected

The extension itself is free and does not gate any features behind a paywall, subscription, or in-app purchase. It displays pricing information for OpenRouter models (e.g., '$0.000002/M input') which comes from the OpenRouter API and reflects the cost of using those models via the user's own API key. The extension does not call any billing API, does not have upgrade/pro features, and does not require payment to use its functionality. The user pays OpenRouter directly for API usage (which may include free credits), but this is external to the extension.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login flow or require a Cortex account. It requires the user to provide their own OpenRouter API key in the options page. The core workflow (summarize, explain, translate, chat) works as long as a valid API key is configured. There is no extension-side authentication, no destination-service account requirement, and no browser-profile dependency.
