Browser ToolBox: AI & Developer Tools

About

Browser ToolBox brings private AI, image tools, page analysis, and developer utilities directly into Chrome.

LOCAL AI TOOLS

Run useful AI models inside your browser without sending your page content, images, or prompts to an external AI service.

• Summarize long webpages
• Ask questions about the current page
• Translate text between multiple languages
• Generate captions for images
• Remove image backgrounds locally
• Convert speech to editable text

Some AI features download their required model files the first time you use them. The models are then cached by Chrome for future use. Processing happens locally on your device, so there are no per-request AI fees or usage credits.

PRIVACY-FIRST PROCESSING

Page content and uploaded files are processed locally whenever possible. The extension does not send your page content to an external AI API. Network access is used only for downloading AI model files and securely verifying optional Pro licenses.

FREE AND PRO ACCESS

The free version includes the core toolbox with daily usage and workspace limits. A one-time Pro license unlocks unlimited daily use, additional pinned tools, workspace presets, accent themes, compact mode, and other customization options.

Turn Chrome into a smarter toolbox for research, development, design, writing, and everyday browser tasks.
