The best part is how fast I can go from idea to something running. Dragging together a workflow that pulls from a knowledge base, runs it through a model, and posts the result somewhere takes an afternoon instead of a sprint. I don't have to file a ticket with engineering and wait. Review collected by and hosted on G2.com.

Honestly, not much. A few rough edges here and there, but nothing that's gotten in the way of what we're building Review collected by and hosted on G2.com.

The product covers the core use case well and is relatively easy to get started with. After spending a bit of time with it, the interface feels fairly intuitive, and it helps centralize tasks that would otherwise be spread across different tools. For basic needs, it works as expected and can save time compared to handling the same processes manually. Review collected by and hosted on G2.com.

Some features still feel a bit limited or not fully polished. Performance can be inconsistent at times, and there’s a noticeable learning curve for more advanced use cases. The documentation could be clearer, especially for new users, and some workflows require workarounds that aren’t always obvious or easy to discover. Review collected by and hosted on G2.com.

StackAI makes it genuinely easy to go from “idea” to a working AI workflow in hours, not weeks. The visual builder is intuitive, RAG setup is straightforward, and the integrations cover most of what I need (docs, links, internal knowledge, apps). It’s great for iterating fast, testing use cases with real users, and then turning the same flow into something production-ready. Review collected by and hosted on G2.com.

As workflows get more complex, debugging can feel a bit opaque and the UI can get busy. Some connectors or edge cases still need workarounds, and I’d love more visibility into step-by-step logs and version comparisons. Pricing can be a stretch for very small teams.

I use Stack AI for building and automating AI-driven workflows without heavy coding. I love how it turns ideas of automation into reality without needing to write extensive code. The platform connects tools, data, and processes, saving me from manually piecing them together. I adore the drag-and-drop logic and minimal scripting, which are perfect for someone who isn't primarily a coder. What I truly appreciate is the Stack AI team's responsiveness; they're top-notch and their quick turnaround ensures I'm not stuck waiting. The speed to value is fantastic, as it allows us to go from an idea to working automation swiftly. Stack AI seamlessly integrates into our business rhythm and provides the confidence to prototype quickly or deliver a solution effortlessly. It excels in providing not just automation, but also an invaluable partnership with the team behind it. Review collected by and hosted on G2.com.

One area we're paying close attention to is security and environment separation. The need for robust multi-environment support, clear delineation between development, staging, and production is critical for enterprise governance. Review collected by and hosted on G2.com.

I find Stack AI easy to use, with a clear interface that stands out, especially for someone like me who does not code. The support I receive is also noteworthy, contributing significantly to its value. I appreciate the ability to create automations through its drag and drop workflow builder, which simplifies the process significantly. This feature enables me to handle tasks such as ticket triage and customer support issues efficiently, demonstrating Stack AI’s robust capability in enhancing workflow without needing technical coding skills.

I am not satisfied with the limited native integrations available in Stack AI. The absence of integration with Spendesk has been particularly notable and impacts my workflow. Additionally, the initial setup was challenging, requiring assistance from a sales engineer. This increase in complexity made the onboarding experience tougher than expected. Review collected by and hosted on G2.com.

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.

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.

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.

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.

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.

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.

I love how Stack AI helps me process documents without needing to go through them manually. It streamlines my workflow with automation, like executing workflows upon receiving emails, reducing manual work. The integration with web scraping is fantastic, capturing relevant data efficiently. The support team is exceptional, responsive to new feature requests, and overall, the platform's user-friendliness and enterprise-heavy integration make it a standout choice for me. Review collected by and hosted on G2.com.

Nothing per say, I believe in the team's commitment and I see it evolving super fast. Review collected by and hosted on G2.com.

Stack AI makes it easy to build and deploy AI-powered workflows without heavy infrastructure setup. The hierarchical dependency system and ability to define reusable nodes/tools is very helpful. Integrations with APIs, knowlegebases, and external services are smooth. Review collected by and hosted on G2.com.

At this point, there’s not much to dislike. The platform is evolving quickly, and while some areas are still being expanded, the team is clearly addressing new use cases and adding improvements at a fast pace. Review collected by and hosted on G2.com.
