What is Merlin?

Merlin is an AI assistant from Foyer Tech that brings models from OpenAI, Anthropic, Google, Mistral, DeepSeek and others into a browser sidebar, opened on any tab with Ctrl+M or Cmd+M. It chats about the page, file or video you are viewing, summarizes, translates, helps write in any text box and adds answers beside search results. One account also works in a web app and in iOS, Android, Windows and Mac apps. A free plan allows a daily number of queries, and a premium plan adds voice chat and premium tools.

Good for

  • People who want an AI sidebar on any website
  • Summarizing pages, PDFs and YouTube videos while browsing
  • Trying models from several labs with one account

Worth knowing

  • Merlin's website answers automated readers with a security check, so its pricing page could not be read and paid plan prices are unverified.
  • Store listings do not give a clear lineup: the US App Store lists Merlin Pro at $20.00 and Merlin Unlimited at $15.00 a month, and Google Play shows items from $3.49 to $499.99.
  • The free plan is capped at up to 102 queries per day, and voice chat, premium tools and team collaboration are described as premium features.
  • The US App Store also sells query top-ups that expire, such as 3,000 queries valid for 30 days at $4.99.
