I have gotten a number of AI chat extensions from AppSumo, including Voila, Merlin, and Nily. I got Dorian for one feature only, which is the screenshot feature that is a one-click way to OCR any text in your screen grab for easy chat access. Some of the others like Nily do this but you have to take multiple steps and create a graphic that has be to uploaded into the chat.

With Dorin AI, you just click the scissors button, select your screenshot, and you can instantly chat with it. It would be nice if there was also a feature to download and save the screenshot, but even so, this functionality will help me with a lot of the work I'm doing.

The interface is clean, there are a lot of great options, and the models include GPT up to 5, Claude, Gemini, and Deepseek. I actually don't like GPT 5 much, so I don't care about that, and I'm fine with GPT40 Mini for the basic tasks. I'd like to see Grok added and maybe some open source ones like Mistral.

MAIN DOWNSIDE: Dorin AI only allows you to be logged in on ONE device at a time. If you login on another browser, computer, or your phone (which there is no app for), you are told you have to be logged out of your other device.

I get that you don't want people sharing accounts but I have a limited number of credits anyway and I want to be able to use this on my multiple computers and browsers, without all this hassle. I think a reasonable device limit of say 10 would be better. This is the one thing I really hate about this app. I'll give it 5 stars anyway since it seems like it's not getting enough attention here on AppSumo. (Dear ModBot, this is the explanation of why I still feel the overall value justifies 5 tacos.)

Other than the device limitation, the price is right on this deal and even if you have other chat extensions, Dorin AI is different enough with some unique features...so I recommend grabbing it.
