Merlin AI is an all-in-one assistant that lives in a Chrome extension and a web app. Instead of opening a separate chatbot tab, you call it up on whatever page you are reading and ask it to summarise, explain, rewrite or answer questions using that page as context.
It gives access to models from several AI companies in one place, so you can switch between them for different jobs. Other parts of the product cover YouTube video summaries, chatting with uploaded PDFs and lecture notes, Projects for saving reusable knowledge, Crafts for turning a prompt into a chart or diagram, image generation and quick email or social reply drafts.
There is a free tier: the FAQ describes a daily allowance of free queries, with larger models using up more of it per question. The homepage advertises a paid plan at $19 without stating the billing period, and the pricing page loads its plan table interactively, so we could not confirm exact plan prices. Check the pricing page before paying.
Merlin says it is available in more than 200 countries, which helps where some chatbots are not offered directly. Paid plans need an international card.
