# Orca Knows

> A clear, current directory of 2,149 AI tools and the companies that make them: what each tool does, what it costs, and what changed, with sources. A product of KOBOKOBO, LLC.

- A price is what the vendor's pricing page said when Orca last read it, with that date.
- A change is reported only after two reads at least 24 hours apart agree, and only when the vendor made it.
- "No public price" means the vendor doesn't publish one. It doesn't mean free.
