Features

Everything you need to compare smarter

⚡

Side-by-Side Browser

Open any two websites simultaneously in a single tab. No more alt-tabbing, split screens, or copy-pasting between windows.

🤖

6 AI Analysis Modes

Compare & Analyze, Price Comparison, Pros & Cons, Recommendation, Summarize, and Key Points. Get structured AI insights for any purpose.

🔀

3 Flexible Input Modes

Site vs Site, Site vs Text (paste a spec sheet, review, or any content), or Text vs Text. Compare whatever you need, however you need.

🌐

Works on Locked Sites

Displays sites that normally block embedding — including Amazon, Apple, Google, and Samsung. Access the pages you actually want to compare.

📋

Flexible Result Panel

View AI results in compact (1/3), half-screen, or full-screen mode. Copy the analysis with one click for use in docs or messages.

🔒

Private by Design

Your Gemini API key is stored only in your browser. No data is sent to or collected by DualyzeAI servers. You stay in full control.
