AI browser extension bringing ChatGPT, Claude, and Gemini to any website

Freemium Launched February 2023Updated March 2026

What is Merlin AI?

Merlin AI is a browser extension that integrates multiple large language models directly into the browsing experience, accessible via a keyboard shortcut (Cmd+M on Mac, Ctrl+M on Windows) on any website. Rather than switching tabs to use AI, users can draft, summarize, translate, rewrite, and ask questions within Gmail, LinkedIn, Twitter, Google Docs, and any other web page.

The extension provides access to multiple AI models including GPT-4, Claude, Gemini, and Mistral, allowing users to select the most suitable model for each task. It includes over 80 built-in utilities spanning AI detection, content humanization, code explanation, slide creation, and voice-to-text. Features like YouTube video summarization, webpage content chat, and document analysis let users interact with web content conversationally.

Merlin's Crafts feature generates diagrams, charts, and code from text prompts, while the Projects feature allows uploading documents or links to create a mini knowledge base for personalized AI responses. The platform also includes AI art generation using integrated Stable Diffusion models. Cross-platform support extends to Chrome, iOS, Android, and Windows.

With support for 128 languages and a generous free tier of 102 daily queries, Merlin serves as a consolidated AI workspace within the browser. The unlimited plan at $19/month provides access to all premium models for less than a single ChatGPT Plus subscription. The extension has a 3.9/5 rating on the Chrome Web Store.
