AI-based products / AI workflow tool

I see there are many tools available that are based on AI. Essentially a wrapper around GPT4o, Claude, etc, to guide the user more effectively. As so many of you are innovating with these kinds of products, I was thinking about creating a free tool where you have a single API request and then you can drag/drop a workflow of AI agents together and finally return the output to the request (or trigger a webhook). So you could have ChatGPT pass to Claude pass to Gemini for example to refine/optimize the result/quality. Would this be of interest? I'd make it so intuitive it would literally be drag/drop the workflow and then you have the single input/output point :) If you are interested, I'd love to hear thoughts including what kind of features you'd like to see.
