Long time AppSumo user - disappointed
Merlin is no longer the tool it once was.
* They are nickle-and-diming users without clearly stating in their UI that things like "web search" cost 2x points for every request --- has anyone else heard of such a thing?
* They LIED about my usage and FAILED to produce (on TWO occasions now) a record of my points and exactly why my points disappeared so quickly, even though they have a record because they explicitly refer to it
* When asking about this and showing them the math, they explained my usage by referring to queries I didn't make at the time I sent the email which shows they are not paying attention
* Have had multiple tickets closed immediately after they were replied to, rather than seeing if I was satisfied - this is a BIG no-no, as I have had follow-up questions every time
I was an early adopted from AppSumo into Merlin and invested a bunch of money into them (one of my biggest AppSumo purchases ever). It's sad to be treated this way after as much as I've loved and enjoyed using this product. This is a failure of 1. the UI not being clear, 2. Lying/falsifying usage stats (if they weren't lying I assume they would want to prove it like I asked them to), 3. Really poor customer service.
Please get it together Merlin. It's rough being treated like a second-rate customer when I was an early-believer in you.

I enjoyed using this Tool - Worth My Investment
I wasn't sure whether to trust this option since plenty of competitors are around with similar offerings. I picked it up because I was trying to save money from paying for ChatGPT or Gemini.
I have benefited from the different options in AI models I can use and the quick to access widget.
Organizing chats is not intuitive but I'm guessing it's related to me not putting enough time to learn how it's all structured. I have been simply using the chats for anything I can think of.
I have also used the image generators several times.
I hope they stay around for a long time.
I like the quickness to interact with the active browser page or the ability the seamlessly change AI models in the same chat. I like that it's quick to respond and not bloated.
I primarily use chats so still need to explore the other tools available.
As for managing the chats, it's a little confusing at times why the delete button only appears in a specific tab and doesn't show up at all in the widget window. There are also a few different chat window versions and they don't have the same functions so I sometimes lose time trying to find out the version I need.
When it comes to history and organizing previous chats, without going into the documentation, it's not intuitive how I am expected to group chats into categories for easy reference and access. ChatGPT gives a quick way to sort chats by date or something else. The "pin" option isn't available in every window so there are some extra steps and friction at times.
Not a deal breaker but that's the first barrier I noticed when using the tool when compared to ChatGPTs interface

Disparition soudaine et inexpliquée du plan à vie Appsummo
J'ai souscrit un abonnement AppSumo qui me donne droit à l'équivalent de 100 $ de crédits d'utilisation mensuels. Le mois dernier, j'ai constaté un changement dans la façon dont vous comptabilisez l'utilisation des ressources. En conséquence, j'ai optimisé mon utilisation pour rester dans des limites raisonnables.
Cependant, aujourd’hui, j’ai découvert que mon compte est désormais marqué comme « gratuit », comme si j’étais un visiteur sans aucun abonnement.
Je compte sur Merlin pour mon travail et j'apprécie sa valeur ajoutée. Mais j'ai besoin de clarté et de transparence sur les ressources que je peux utiliser chaque mois. Ces changements récents me posent de sérieux problèmes.

Lifetime Access Removed Without Warning – Misleading and Unprofessional
I purchased a lifetime plan with Merlin, expecting long-term access to Pro features as promised. Everything worked for a while, then suddenly my access was removed or severely limited — with no explanation, no email, and no clear communication.
I reached out to support and received:
No clear answers,
No fix or restoration of my plan,
No transparency about what happened.
