Merlin AI
What it is
Overview
A browser extension that puts ChatGPT, Claude, and over 10 other AI models behind a single keyboard shortcut on any website. Merlin AI is a wrapper that routes requests to different frontier models without opening separate tabs. Early reviewers praise the multi-model access and cross-site integration, though system reliability emerges as the primary friction point. The audience skews toward content creators, researchers, and students managing multiple AI tasks across different sites.

Built on another provider's modelWraps ChatGPT
Merlin AI is primarily a user interface that aggregates existing AI models like ChatGPT, Claude, and Gemini in one subscription. While convenient for accessing multiple models, it doesn't offer proprietary technology, specialized fine-tuning, or significant workflow innovations beyond what you'd get from using the original AI services directly.

“The best thing I like about Merlin is that it gives me all of my favorite LLMs in one place, and I get to compare responses. If there's a particular LLM that does one thing better than the other, I get to do all of that in one centralized location without switching tabs, which is why I give it 5 stars. Merlin is great! Not only that, but it's multimodal, so that helps as well.”
“Except for very basic questions this platform struggles to provide complete and correct solutions. Most of the time projects do not complete, or if they do, they are not correct. Almost none of the image related tasks worked. I even opened multiple tickets and provided examples and nothing was done to correct the problem. I do not recommend this solution.”
“Worst ai fraud the people ”

“You need to topup sometimes for heavy usage. I made a 3d world using chatgpt astra in merlin!! Best $5 ever spent. Actual Chatgpt plan starts from $100 which is tooo expensive”
“There are so many issues, it sleeps and doesn't respond back. you keep on wasting redo button again and again. and after one query, it says monthly credits exhausted. what a joke. If i could, i would ask my money back.”
“I love the way getmerlin provide me access to a wide range of powerful AI models. Getmerlin is fast and responsive. This is such a cost effective way to leverage AI because I avoid having to buy multiple monthly subscriptions. It's all there in one place.”
“Rip off. I used up all my month's credits in one unfinished thread”

“very most Fake service provider I had seen in my whole life, showing something and found nothing. showing liberty but only 2k uses for one month and renews in after 1 month till then what we do??? no any uploads options and given options also not working even their internal vault ilso not working and their refund policy is only to show no any revert and support for concerns. *DO NOT BUY MERLIN THEN AS WELL WHEN THIS IS A LAST SERVICE PRODIVER IN THE WORLD*”
“nothing at all I find Merlin to be a very fake platform with fake deals and it's not supportive for issues and refunds. They show something but you find nothing, plus they claim unlimited services but offer only 2k uses a month. It's confusing how they count uses. Also, there's no option to attach files for support and even their internal vault isn't working. Free versions of AI are better than Merlin. n/a”
