What it is
An n8n community node that lets workflows ask several typed questions about the same state and receive calibrated probabilities for classification, routing, verification and scoring. For n8n users who need structured decisions instead of generated prose.
How it uses Jev
Jev answers Choice, Yes/No (noul) and Score questions defined over workflow state. The node validates the schema, sends the state and questions, and returns answers under each question's Name. Results can be appended to the item, returned as the full response, or simplified to the single value used for branching.
Primitives:choicenoulscore
Technique worth stealing
Ask several independent typed questions over one state in a single node execution and branch on the simplified answers.
Try it
In n8n: Settings → Community Nodes → Install → n8n-nodes-typesafe-jev
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
