Build an AI workflow without giving up control

Choose a reversible first process

Start with classification, extraction, summarisation or a draft that a person reviews. Avoid autonomous payments, deletion, public posting or high-stakes decisions during an early pilot.

A safe workflow pattern

Use a trigger, input validation, minimal context, a structured model response, deterministic schema checks, human approval for external actions, and an error path with bounded retries. Log enough to diagnose failures without storing unnecessary sensitive content.

Check current nodes and integrations in the official n8n AI documentation.

Operate with least privilege

Create separate credentials with only the required access. Set timeouts, cost limits and a kill switch. Test normal, empty, long and adversarial inputs. A deterministic workflow is often better than an agent when the steps are already known.
