Discover what Merlin AI is, a Chrome extension that brings AI models like GPT-4 and Claude to any website for writing, summarizing, and coding.

Merlin AI is a Chrome extension that brings AI assistance into your browser. It taps into models including OpenAI’s ChatGPT, GPT-4, GPT-4o, and Claude-3, so you can generate AI responses wherever you are online — on Google search, YouTube, blogs, LinkedIn, Twitter, and Gmail. The extension is designed to be easy to use, with shortcuts that work across different websites. A free tier gives you a daily allowance of 102 queries for writing, summarizing, and translating.
Merlin was created by Pratyush Rai, Co-founder and CEO, who has an engineering background and previously worked at BCG. The company behind Merlin is called Foyer, and Pratyush started it with Siddhartha Saxena, Sirsendu Sarkar, and Puneet Bhatt, along with a team covering engineering, product design, marketing, and operations.
Merlin AI suits content creators, developers, marketers, engineers, and customer support teams who want AI help directly on the websites they already use.
Merlin offers a free tier with 102 queries per day, giving access to models such as GPT-3.5, GPT-4, Claude, Opus, Llama, and Mistral. Note that each use consumes a certain number of queries, with the exact cost depending on the model and task. For individuals, the Merlin Pro plan is the fit; teams can choose Merlin Teams, which offers plans tailored for group use.
