Merlin

What is Merlin?

Merlin is an AI assistant delivered as a Chrome extension and a web app. It lets you chat with models from several providers in one place, including GPT, Claude, Gemini, DeepSeek, Mistral, Llama and Grok, and ask about the page you are reading without switching tabs. People use it to summarize web pages, YouTube videos and PDFs, answer questions about uploaded files, draft emails and social posts in Gmail, LinkedIn and X, and turn videos into blog posts. Projects let you build reusable knowledge bases to query with citations, Crafts generate diagrams and interactive charts from a prompt, and custom chatbots and a prompt library help with repeat work. A Teams version adds a shared dashboard, seat management and a statement that team data is not used to train models. The Teams page shows $19 monthly per seat, with a $95 total for five members, and a yearly option that saves $240.
