I'd been using Harpa AI for some time, then they changed the plans and it stopped being as useful to me. In steps Merlin and I'm loving it!

Merlin is an advanced AI assistant that follows you round the internet thanks to the browser extension.

Compared to some AppSumo deal, this feels like a mature product and it offers a wide array of features designed to enhance productivity and streamline various tasks across the web.

Tier 1 lets you give it a try, but tier 2 is the sweet spot for me as it has a generous credit allowance and the flexibility to use your own API key, making it a versatile tool for both casual and heavy users.

Key Features

1. Multi-Model Access: Merlin allows users to access a variety of AI models, each with its own cost structure. From the economical 3.5 model to the more advanced and expensive Opus model, you've a broad range to experiment with.

2. Web Integration: One of Merlin's standout features is its seamless integration with the web. Whether you're searching on Bing, drafting emails in Gmail or Outlook, or creating posts on LinkedIn, Merlin is there to assist. It even helps with YouTube by grabbing transcripts and generating content like tweets and blog posts.

3. Chat Interface: The chat interface is user-friendly and familiar to those who have used tools like ChatGPT. Users can also chat with documents, create chatbots, generate images, and use a code interpreter.

4. Chatbot Creation: Creating chatbots is straightforward with Merlin. The AI assists in generating the bot by filling out a form with the necessary details, making it easy to customize and tweak as needed.

5. Mobile App: Merlin is not confined to desktop use. The mobile app offers the same range of features, including web access and various AI models. This makes it convenient for users to access Merlin's capabilities on the go.

So far I've had a very positive experience. The tool is intuitive and easy to navigate, whether you're using it on a desktop or mobile device. The Chrome extension is particularly useful, providing quick access to Merlin's features across various web platforms.
