n8n
Persistent memory for n8n workflows via Hindsight. The @vectorize-io/n8n-nodes-hindsight community node package adds three operations — Retain, Recall, Reflect — that work alongside any other n8n node.
Why this matters
n8n is the connective tissue of automation: triggers from Gmail, Slack, Sheets, Stripe, Notion; actions across 400+ apps. Until now it has been stateless — every workflow run starts fresh. With Hindsight nodes you can:
- Retain every closed support ticket, sales-call summary, or form submission into a memory bank
- Recall relevant context before an OpenAI / Anthropic / Cohere step so the LLM sees prior history
- Reflect to ask synthesizing questions ("What do we know about this customer?") right inside a workflow
Installation
In your n8n instance, go to Settings → Community Nodes → Install and enter:
@vectorize-io/n8n-nodes-hindsightOr for self-hosted n8n:
cd ~/.n8n/custom
npm install @vectorize-io/n8n-nodes-hindsightRestart n8n; the Hindsight node appears in the node panel.

Example workflows
Customer-support assistant — every closed Zendesk ticket retains the resolution. Every new ticket starts with a recall against the bank to surface similar past issues, then passes that context to OpenAI to draft the first reply.
Sales-call coach — Gong webhook → Hindsight Retain (call summary). Before each next prep call, recall on the prospect's name to pull every prior touchpoint, then format into the daily prep doc.
Personal Slack bot — Slack DM trigger → Hindsight Recall on the user's question → OpenAI for the answer → Slack reply. The bot remembers every conversation across sessions.
