n8n for AI workflows
n8n is a powerful workflow automation tool you can self-host or run in cloud—ideal for complex branching, retries, and keeping data inside your boundary when required.
Official vendor: n8n.io
Why n8n + Aristral
We treat n8n as orchestration for RAG ingestion jobs, scheduled syncs, and human approval loops. LangChain handles LLM composition; n8n handles reliable plumbing.
What we build with n8n
Orchestrate nightly document ingestion pipelines that pull new PDFs from a shared drive, extract structured fields, validate confidence scores, and write results to a database.
Run human-in-the-loop approval workflows for AI-drafted emails — routing to a manager if the model confidence is below threshold before anything sends.
Schedule and retry API polling jobs for lead enrichment services, with dead-letter queuing so no record is lost on failure.
