Merlin AI is a unified AI assistant that lets you research, write, summarize, and switch between top AI models — all from a browser extension or app.
Merlin AI (GetMerlin) is an all-in-one AI assistant available as a Chrome extension, web app, and mobile app. It integrates multiple advanced AI models (GPT-4, Claude, Gemini, DeepSeek, and others) under one interface so users don’t need separate subscriptions.
