Ask a decision model.
See how sure it is.
Ochra Lab is where you try AI decision models live. They do not write paragraphs: they read a situation and return typed answers with a probability on every option. Jev takes hundreds of questions in one request, and in Five hundred at once all 1,500 answers come back in under three seconds.
“We got billed $4,800 twice on the 3rd. Also since Friday the CSV export does nothing, console shows a 500. Board review Thursday. Third time this quarter. Considering moving to a competitor.”
What is this message primarily about?
Confidence 0.46, because the message genuinely is both — so it did not pretend to pick one. In the same request it was certain about the parts that were certain: this customer is threatening to leave 0.99, and the damage is severe 1.00.
