I have a startup called Notify Me (notify-me.rs) whose main idea is to be a simple service for tracking web page updates. Not sure what exactly you need, but feel free to try it out / reach out if you have any questions.
We are trying to make it as hands-off for end user as possible, but just plugging AI into it is that easy as it seems, since you need to make sure that you are alerting for legit changes and that nothing is hallucinated by the AI
Hey, sorry for the slow reply, didn't get any notifications from this site.
Sustainable - Perhaps, we have daily signups but people are not converting to paid users. I plan to change are pricing strategy to credit based usage, and I'll see if that will improve things.
We are also going into e-commerce direction with a spin off product, so hopefully that will go a bit better.
Do you mind sharing what is the tool that you build?
If you do give it a try, let me know what you think, since I'm one of the founders.
Cheers!
