Good tool, horrible support

I've been using merlin for about 9 months now and generally like the tool but your support and user manual are absolutely horrendous.

The support team doesn't know or understand the tool, they are not even aware of some of the features and connections offered, and the 'instruction videos' you provide are not much use either. I feel like I could be getting way more from Merlin if only there was someone who could answer my questions or better instructions.

Adding new features and integrations is great but there needs to be proper documentation and support so that people can actually make use of them! Perhaps it's time you stop chasing that new shiny object and devote some time to fine tuning the features you already have and building a proper user manual + training your support team.

Are you planning on addressing this any time soon?

One of the best Appsumo Deals

I purchased Tier 3 and love Merlin so much. I use it many many times per day. This is by far one of the best deals I have purchased on Appsumo. They update new features very frequently. Absolutely TOP!

I'm very happy with this deal

The fact that some here criticize the AIs themselves is not very intelligent, because Merlin only provides the wrapper for different AIs to choose from.
You can choose from all relevant AIs, even the newest ones!
And if they are cheap, you benefit just as much, as with DeepSeek (only 1 credit).
As this was a LifeTime promotion, the providers must of course also cover their own costs, so you should be fair in your assessment.
It is very positive that you can report suggestions for improvement and that someone from the Merlin team always responds. Exemplary!

Badabababa, I'm lovin' it!

I bought this item over a year ago, and I know it's not currently available, but I felt I owed a quick review. This is the single most used item I have ever bought from AppSumo. The amount of insane AI creation options and image creation is really amazing. I use it daily and run out of darn credits every single month. I've seen complaints about this, but I feel the value is fair for what I paid. If this one ever comes back here, I'd highly recommend it to anyone on the fence.

Cheers Merlin crew, thanks for the continued development of a really cool product.

Was very happy but

A tool is useful, but.
Credits usage for Sumolings is very high.
• Claude 3.7 sonnet uses 60 credits, but actually uses 120 per query with internet search.
• O1 180 credits
• GPT 4.5 400 credits (this means 50 queries per month on tier 3, whitout internet search)
• Claude 3 sonnet 50
• GPT 4 longer output 50 credits
• GPT 4o mini 1 credit
Reccurrent new buyers promotions is $5 USD unlimited per month. We paid about upt to 4 years in advance that, and even in tier 3 credits run like sand in water, and to get unlimited in existing Sumolings accounts is $9 per month.
• No video, currently available to other similar services
• No audio.
If things improve, sure, I will change the review.

Merlin ist nutzlos und halluziniert endlos

Puh, Merlin ist furchtbar. Das Tool halluziniert endlos und schafft es weiterhin nicht eine Frage, deren Antwort 1:1 im Text steht herauszufiltern. Absolut unbrauchbar.

Delighted

I'm really happy with Merlin. It brings AI intelligence into the places where I need it and adds a really nice usable layer.

really good,i like that

Merlin updates their AI model from time to time, which I really appreciate.You should try it. However, it’s a bit disappointing that these updates aren't included in the Pro plan,still consider should i hold the product.

Mixed Experience - Great Features but Credit System Issues

PROS:

Impressive integration of multiple AI models (GPT-4, Claude-3, Gemini, etc.)
Convenient Chrome extension that works across websites
Useful features like YouTube summarization and social media content generation
Clean interface and good website/PDF analysis capabilities

CONS:

Serious issues with the credit renewal system
Customer support needs improvement
Unclear communication about billing cycles

DETAILED REVIEW:
I purchased the License Tier 2 plan (12,000 credits/month) in November 2024. The tool itself is quite powerful and offers great features for content creation and research. The ability to access multiple AI models from one interface is a genuine time-saver.
However, I've encountered a significant issue: the monthly credit renewal system isn't working as advertised. Since my initial purchase, the credits haven't reset monthly as promised. The renewal date keeps shifting without explanation (recently moved from January 23 to February 23), effectively leaving me with just the initial 12,000 credits for an extended period.

Great product. Happy with the purchase. Ease of access to complex Ai models.

I was first confused on if I need such product in my toolset. But now, it is the only product I use every other hour in my daily work life. Hats off to the team.

Great tool, and they're adding new models on the go

So far, so good! I use this tool daily, and I can confidently say that it provides responses that are on par with what the original ChatGPT or Claude can deliver. To test this, I copied and pasted the same prompt into both Claude and Merlin, choosing the same Claude 3.5 model, and the responses were identical. While the language may vary, the output is what truly matters to me.

One request I would like to make is regarding the YouTube summary feature, which I find very useful. It would be great to have a separate window or tile dedicated specifically to YouTube summaries, similar to the chat option. Currently, the summaries are displayed in the chat area, making it difficult to find other conversations. The same goes for other live features—having distinct tabs for summaries, chat, and other functionalities would really enhance the user experience.

Additionally, considering that Deepseek is also free, how do you differentiate your platform? I noticed that using credits is required on your platform, whereas it is currently free on Deepseek. What future plans do you have to address this distinction?

So far so BAD

The system says that my OpenAI API key is registered and accepted, but when I try to use Merlin's functionality (ANY of it), the system keeps throwing error messages that "Something went wrong. The error message from OpenAI is: Status code 429, Too Many Requests"

Merlin 'support' says that my key was invalid, so I generated a new key. Same problem, again.

Merlin support is VERY slow to respond.

Very frustrating. Unfortunately, I cannot recommend this product.
