"It helps me with keeping my creative process organized and efficient."
What do you like best about Stack AI?

For me the best thing is how much time it saves on the prep work. I can take messy client notes or long reports and turn them into something usable, like a creative brief or a quick summary, without spending hours doing it manually. It’s also great for brainstorming — I can quickly explore different campaign directions or generate first drafts of presentation copy, which helps me get to the actual design and strategy part faster. Since we work with a lot of different types of clients, I like that Stack AI is flexible enough to adapt depending on the project. Review collected by and hosted on G2.com.

What do you dislike about Stack AI?

Some of the features aren’t super intuitive at first, so it does take a bit of trial and error to figure out the best way to set things up. I think the interface could be a little smoother, especially for people who don’t come from a technical background. Also, I’d love to see more integrations or templates that are geared toward creative work specifically — that would make it even more useful for people in my role. Review collected by and hosted on G2.com.

Response from Guillem Moreso of Stack AI

"Super easy to use, super powerful results"
What do you like best about Stack AI?

Really powerful platform, incredibly comprehensive suite of integrations (Sharepoint, SAP, Workday, Google Drive, tons more). Drag and drop UI is nice for team members who aren't sure how to start coding AI agents. Nice that you can export agents as forms, websites, chatbots, in Slack etc. -- a lot of other agent building platforms don't have that tool and you have to make a whole website for other ppl to use it. Also very secure w/ lots of built in features: PII protections, guardrails so that chatbots don't go off on their own, SSO, passwords, etc. and compliant w HIPAA, SOC2, etc. Review collected by and hosted on G2.com.

What do you dislike about Stack AI?

So many options, tools, and templates that it can be overwhelming sometimes to know where to start-- but I find the Chat with Workflow function really helpful and ask it questions all the time, like how to debug something, how I could add a certain tool into the workflow, or even to just generate a workflow for me Review collected by and hosted on G2.com.

Response from Guillem Moreso of Stack AI

Thanks for the detailed feedback! We’re glad the integrations, export options, and security features are helping your team. Totally hear you on the “so many options”—we’re working on making the starting point even easier. Love that Chat with Workflow is giving you a boost!

"Slightly steep learning curve, but once you get there, it's extremely rewarding"
What do you like best about Stack AI?

As I mentioned earlier, the learning curve can be a bit steep, but once you become familiar with it, the results are truly impressive, and the building experience becomes almost self-explanatory.

The range of LLMs you can integrate is remarkable, and the granular settings available for each LLM make it suitable for nearly any use case.

The ability to stack workflows is definitely a unique element of the product. This way, one can avoid building a massive workflow and instead build smaller increments and then connect them in a master flow. Review collected by and hosted on G2.com.

What do you dislike about Stack AI?

Understanding the memory settings can be tricky when it comes to recurring tasks, and expert input on how to best use this feature is potentially needed.

There are a couple of tricks that allow one to work most effectively with the tool, but they are not highlighted during the onboarding. One powerful example that I learned through trial and error was formatting the prompt so that it's almost entirely separate from the instructions. In the examples below, assume _content_ to be a text output from a previous node (either long or short formats).

Example for how it shouldn't be formatted: "Assume the role of X, and based on the _content_, generate an overview of the findings around Y."

Example for how it should be formatted: "Assume the role of X, and based on the text provided below, generate an overview of the findings around Y.

___________

_content_

___________"

This way, the working LLM works better, but this approach to contextualisation doesn't come automatically for most, and I believe this could definitely be a highlighted tip during onboarding. Review collected by and hosted on G2.com.

"Powerful and intuitive for building AI-powered workflows"
What do you like best about Stack AI?

StackAI is an outstanding platform. The workflow builder is easy to use yet incredibly powerful—it lets you create complex, automated processes with AI agents without needing to code. The AI agents are flexible and smart, and they can handle a wide range of tasks. I’ve been able to streamline and automate parts of my work that used to take hours. The interface is clean, everything runs smoothly, and the team behind it is clearly focused on constant improvement. Highly recommended if you want to harness AI in a practical, effective way. Review collected by and hosted on G2.com.

What do you dislike about Stack AI?

I’d love to see more pre-built templates or example workflows. While the workflow builder is intuitive, having a wider variety of templates would make it even faster to get started or explore new use cases. Review collected by and hosted on G2.com.
