Highlights
- Sends a state plus Noul, Choice, and Score questions to POST /v1/systemone in one request.
- Returns calibrated probabilities and confidence for each question so workflows can branch on typed answers.
- Can emit one output branch per question, labelled with the question id.
- Checks each answer's type and value against the question before it reaches downstream logic.
- Simplify mode is off by default because it discards probabilities and confidence.
Questions about this entry
Short answers drawn from the linked project or page.
Add the TypeSafe community node, choose the Ask Questions operation, provide a state and a map of Noul, Choice, or Score questions, then branch on the returned probabilities and confidence.
The node supports Noul questions, which return a 0–1 probability that the answer is yes; Choice questions, which return one option plus per-option probabilities and confidence; and Score questions, which rate against ordered levels and return a probability-weighted score, legend, probabilities, and confidence.
No. All questions in the node are sent in a single request to POST /v1/systemone and evaluated in parallel against the same state. Output Mode changes only how answers are delivered, not the number of API calls.
Simplify reduces the full response to a map of question id to value, such as is_urgent: 0.92 and department: technical. It is off by default because it discards the probabilities and confidence that indicate whether a judgment is safe to act on.
It checks that each answer's type matches the question and that its value is usable, such as a noul from 0 to 1 or a choice from the listed options. A failed check fails the item with an error naming the question; with Continue On Fail, that item arrives as an error object.
Yes. Set Questions Source to JSON and describe every question in one object using the same shape as the TypeSafe API questions field. JSON can be written in the node or supplied by an expression. Repeated keys are dropped silently, and numeric keys are ordered ahead of other keys.
n8n stores connections by position, not by name. Adding, removing, or reordering questions shifts the branches underneath existing links without warning, so check the connections after changing the question list when using One Output per Question.
