- The transcript feature for Youtube videos used to work so much better, with a cleaner UI. You used to be able to copy entire Youtube video transcript with or without timestamps, quick and simple. The more recent updates have downgraded it lol.

- it is not even loaded in Gmail, what a shame, it used to be good, something was changed in the last update...

- Merlin AI used to be a fantastic, seamless extension that genuinely made browsing and writing a breeze. Ever since their recent update, it’s turned into a clunky, intrusive, and completely broken piece of garbage.

- This used to be great at summarizing YouTube videos. Now it doesn't work. At all. Worthless.

- It was a good extension, I paid for it, this is my second year that I extended my subscription. However, it is not working anymore. I give all the details including screen shots to their support, they are NOT doing anything about it. They are good taking your money and NOT providing the service for it. There was a guy, supposedly looking into it, Shubhankit he just closed the ticket and left it alone doing nothing about it. This is a horrible service. They have all the details, they know about it, and simply ignoring. UNACCEPTABLE. SHAME ON YOU MERLIN AI PEOPLE.

- I have a lifetime license via AppSumo and highly recommend you do not install this extension. It now injects annoying "charitable" ads from a service called Give Freely. Expect to see annoying hard-to-close popups that guilt-shames you whenever you try to shop *anything* online. If they are willing to sell-out their paying users and bother them over and over in such an intrusive way, akin to installing malware on your computer, then what are they then doing with your data? Probably nothing good. I don't trust the people and company behind Merlin one bit. Will report/flag concern with both the Chrome Web Store and Apple's....

- Love this extension. Does exactly what I want. Thanks Merlin!! And when writing this review, i saw someone else was complaining about a popup. I went looking for it (hard to find), and it was offering a free donation to charity. OMG - what is anyone complaining about? And there was a very clear button that says 'close popup', and if you press that, you can prevent the popup from every showing again. Net net - Makes me love Merlin even more!

- Can confirm that Merlin is injecting ad-ware code into sites. Was making a purchase and saw a popup dialogue that had no safe exit element, but did have a link to here: https://givefreely.com/charity-ad-why?p=merlinprod If you do use this extension then I would recommend going to the 'Manage Extension' option and enabling 'On click' under site access. This way Chrome will not allow Merlin to inject code on sites that you don't explicitly allow it to.

- - Unless you switch to old UI, sidebar signin button just redirects to the "extension installed" webpage and does not allow actually using the service otherwise. - They did not add GPT-5 still - The "Submit" button on their "We are sad 😢 to see you go" page does nothing!

- Merlin is a game-changer! I use it daily to summarize articles, generate content, and even create images. It's fast, reliable, and saves me so much time. Highly recommend for students and professionals alike.

- It really feels like they’re throttling their users. It used to be pretty good, but now all I get are a couple of lines no matter what I ask, even if the old Claude could handle full articles with barely any effort. Plus, everything is painfully slow the site, the chat, you name it. And what’s with this new “Flow” thing? It honestly unnecessary and doesn’t help at all. Perplexity and Manus are far, far better options!

- It kept prompting me for payment, but since the main features didn't have a trial option, I decided to switch to TinaMind, where all the premium features are offered at a reasonable price.
