As you well know by now, AI tools have become all the rage. You have ones writing content for you and those creating avatars and artistic impressions. There’s a new open-source browser extension on the block called Merlin: Open AI ChatGPT, and it’s here to enhance your browsing experience.
It’s currently available on Chrome, Firefox, Edge, Avast Secure, and any browser using Chromium.

Merlin lives as a plugin on your browser, which you can access with Ctrl+M on Windows and Cmd+M on Mac. The AI extension has several functions, the main one helping you write or summarize content. Here’s a quick overview of what it can do:
- Reply to an email if you provide the original mail
- Summarize online articles from links you paste
- Give you advanced formulas for your sheet based on your prompt
- Deliver an overview of your thesis or guide that you can give to your readers
- Pretty much rewrite an article for you
At the moment, the developer has made Merlin: Open AI ChatGPT free to use, but it won’t be like that for much longer. They’re busy working on a paid version with more functions and no limits. That’s to be expected, as they put in quite a bit of work to make this happen.
I’m personally wondering how many more apps and plugins we’re going to see with ChatGPT as the basis. Even though it’s open-source, there may come a point that the developers of ChatGPT may want to see some royalties. Wizards of the Coast tried that stunt with Dungeons & Dragons. Fortunately, the gaming community stood up against the ruling and had it retracted.
In any event, Merlin is here to weave its magic on your browser, whipping its virtual wand and helping you write professional content. All of you who are really bad with emails and written interviews can now rejoice.
