Jev came out in September from TypeSafe AI. One of its founders worked on ChatGPT at OpenAI. It doesn't write text. You give it some text and a question with set answers, and it picks one and scores how sure it is. https://www.typesafe.ai
What that looks like
"Is this email a new lead, an existing customer, a complaint, an invoice or spam?" You get back a label and a score, like lead 0.94.
Why it's useful
It can't make up an answer, because it can only pick from the ones you set. It can still pick wrong, which is what the score is for. It answers in about 70 to 500 milliseconds.
Three places I'd plug it in first
Inbox sorting. Label every new email and route it.
Lead scoring. Score every web form and call the highest first.
Urgency flags. Only get a text when it's confident a message is urgent.
The rule that keeps it safe
Only act when the score is above a number you choose, say 0.9. Everything else goes to a person.
What you need
It's an API, so it goes inside an automation tool like n8n or Zapier. You pay $0.042 per million input tokens, and its answers are free.
