If I remember correctly, one has a year to patent an invention once it is publicly disclosed so I don’t see how this service offers any protection

How does disclosing an invention protect it? Protect it from what and for how long? If a patent isn't filed eventually then competitors can file.

Why not publish the invention on a blog?

Why not keep the invention a secret?

It's not so much for founders. Founders should just do the idea; see if others are doing it first. Form the LLC that can roll over and die if it smacks into a patent.

Your customers are the patent lawyers who need to do that research.

Your competitor is every AI.

There is no poor man’s patent.

Invention might not require them, but “patent” always means lawyers because patents are entirely a legal construct. Good luck.
