Why this matters

An AI tool should not only be available. It should also be helpful, fast enough, and easy for people to trust.

What to look at

  • Is it available when people need it?
  • Is it fast enough?
  • Are the answers helpful?
  • Is the cost reasonable?
  • Does it fail in a safe way?
