BananaX is a Chrome extension designed to automatically generate infographic images from X (formerly Twitter) post text. The extension creates visually appealing graphics that can be attached to social media posts with minimal effort.

The key features include one-click infographic generation from post text, automatic attachment of generated images to the post form, multi-language support for English, Japanese, Korean, and Simplified Chinese interfaces, customizable prompt pattern settings, aspect ratio selection options including 1:1 and 16:9 formats, and automatic hashtag insertion functionality.

The extension works by reading post content on X and sending it to Google's Gemini AI service to generate infographics. Users need to obtain a Google Gemini API key from Google AI Studio and configure it in the extension options before use.

The primary benefit is creating eye-catching graphics that can increase social media engagement. The tool is designed for users who want to enhance their X posts with visual content without requiring design skills.

Target users include social media managers, content creators, and X users who want to improve their post engagement. The extension integrates with Google's Gemini AI API and requires Chrome or Chromium-based browsers.
