"CustomGPT.AI Delivers Powerful Multi-Agent Automation"
5/5
What do you like best about CustomGPT.ai?

I run a cybersecurity advisory firm, and I’ve been evaluating CustomGPT.AI since July. We’re still building and testing, so I wouldn’t call us fully deployed yet. That said, I’ve already built an advisory agent that works from our own material, a tech desk agent, and a multi-agent setup I call “Ask Ryan” that routes questions across agents.

The multi-agent functionality was easier to get working than I expected. Almost everything I do goes through the API because I’m integrating this into our own tools. The API has been straightforward, and I was able to get things working without opening support tickets.

The agentic actions are where I’m seeing a lot of the value. One question can trigger several steps and bring back a more complete answer. In cybersecurity, it’s critical that the response is grounded in our own guidance and shows where the information came from. CustomGPT.AI has been doing that in my testing. Review collected by and hosted on G2.com.

What do you dislike about CustomGPT.ai?

I’d like better visibility into how questions move through the multi-agent setup. When Ask Ryan routes a question across agents, I want to see which agent handled each part and how it contributed to the answer.

Right now, finding that information takes more digging than it should. It’s a specific improvement, but it’s the one I keep coming back to as I build this out. Review collected by and hosted on G2.com.

"CustomGPT: Helpful Team, Strong Usability, and SOC 2 Peace of Mind"
5/5
What do you like best about CustomGPT.ai?

I find both the team and the usability of CustomGPT extremely helpful. The SOC 2 compliance is a big plus, and knowing that when I’m using this AI tool my information stays confidential and private makes both me and my users feel much more comfortable. Review collected by and hosted on G2.com.

What do you dislike about CustomGPT.ai?

The most challenging part is getting used to the interface. Once you understand it, it’s great, but it does take some time to learn all the different options and levers. So that, when the chat is live, the experience matches what you intended. The good news is that the online tools and the team make it easy to see what’s missing from your setup and how to fix it.

4.5/5
What do you like best about CustomGPT.ai?

The ease of use; it is incredibly simple to set up an agent and get high quality results. They also have a very supportive team. Review collected by and hosted on G2.com.

What do you dislike about CustomGPT.ai?

There is some rigidity on the features: max number of characters per prompt, or size of documents users can uploads. It also seems really easy to burn through query credits quickly if you don't monitor it. Review collected by and hosted on G2.com.
