About Merlin
Merlin is a browser extension that puts GPT and Claude in a sidebar on any webpage, with built-in chat history.
It overlays both OpenAI GPT and Anthropic Claude in one sidebar interface, so you can use either model on any page and review past conversations from built-in history.
It fits people who want an AI assistant beside whatever they are reading, on a freemium plan with free use plus paid upgrades. It is a poor fit if you need heavy daily volume, since the free tier caps daily queries, or if you work outside the browser, since it is not a native desktop or mobile app. Model choice is limited to GPT and Claude, with no other providers or local models.
