I bought the 3 Code one for Dorin. I was worried about what it is and what it does, but it’s basically an AI assistant that follows you around on pages and can be used for many different purposes. I was surprised by how good it is, so I had to give a good review. I have many AI chat options, but none do quite as well as this—not even Merlin, which is similar. I also use Nily to some extent to help.

What separates it is the number of useful options at my disposal. For example, I use the X app a lot, and I can quickly fix my grammar when I type. Mind you, I have X Premium+, but it often changes my words; here, I can just fix grammar with little loss.

Another good feature is that it seems to have some sort of OCR, as it has a screenshot option I use when I see Korean text for my K-pop; it lets me chat with the text so I can easily understand it. To test this feature, I tried a long Japanese interview on Dragon Ball Daima; many AIs translated it wrong (guessing no OCR), but this one got it scarily right—even the names. You can also just save the image and ask it.

Even more, you can legit ask it to translate an entire page, and it will do so! I translated a Korean page (Kstyle) talking about the K-pop group TWICE by simply asking it to—that’s insane.

It has some great models—GPT-5, Claude 4 Sonnet and Opus, and Gemini 2.5 Pro—so if, like me, you prefer top models, you’re covered.

Also, it can be used to chat with YouTube. YT has its own Ask feature, but sometimes the option isn’t there, or they can’t really help me in the chat. Dorin is hella useful and always there. You can choose your model, too (I found this helpful; for example, GPT-5 sounded a bit biased on one video, so I switched to Sonnet for that video).

It also sticks around more than, say, Nily or Merlin, which sometimes disappear or are unusable depending on the site. And it can just be used as an AI chatbot if you want to ask questions about anything.

Also has a playground if you click on the full page meaning you can ask a question and up to 6 Ai's can answer it so you can compare.

It has many other use cases, but these are some super useful ones I’ve found. My only complaint is that sometimes, if it hovers somewhere, you can’t move it to the side, which can be a tad annoying—so a quality-of-life upgrade would help. Maybe add more models like Grok 4 or Claude 4.1/4.5, but the models available are top-notch, so these are just minor criticisms.

Overall, what are you doing? Why isn’t this a steal yet? I highly recommend it before it’s gone.
