Merlin AI
One subscription, every major AI model, right in your browser.
What is Merlin AI?
Merlin AI is a browser extension and web app that puts multiple LLMs (GPT-4, Claude, Gemini, Llama) behind a single chat interface, plus tools to summarize pages, draft emails, and chat with PDFs or YouTube videos. It targets individual knowledge workers and students who want one subscription instead of paying each model vendor separately. The pitch is convenience and price, not depth.
General AI assistants for research, writing, analysis, planning, and daily knowledge work.

Power browser users who prefer extensions over standalone apps
Business fit
Right for you if you bounce between ChatGPT, Claude, and Gemini all day and resent paying $20 to each of them.
