Description

@vectorize-io/n8n-nodes-hindsight

Hindsight memory nodes for n8n — give any n8n workflow persistent long-term memory with retain, recall, and reflect operations.

Drop a Hindsight node anywhere in a workflow to:

• Retain facts emerging from a workflow (form submissions, CRM updates, customer chat) into a memory bank
• Recall relevant context before an LLM step so the AI sees prior history
• Reflect to get an LLM-synthesized answer over the bank’s accumulated knowledge

Installation

In n8n, go to Settings → Community Nodes → Install and enter:

@vectorize-io/n8n-nodes-hindsight

Or install via npm in your self-hosted n8n:

cd ~/.n8n/custom
npm install @vectorize-io/n8n-nodes-hindsight

Restart n8n and the Hindsight node appears in the node panel.

Setup

1. Create a Hindsight account at Hindsight Cloud (free tier available) — or self-host with the Hindsight installer
2. Get an API key from the Hindsight dashboard
3. In n8n, create a new Hindsight API credential:
– API URL: https://api.hindsight.vectorize.io (or your self-hosted URL)
– API Key: your hsk_... key (leave blank for unauthenticated self-hosted)

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.

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.

Personal Slack bot — Slack DM trigger → Hindsight Recall on the user’s question, pass through to OpenAI node, reply.
