Flowise

Persistent memory for Flowise chatflows and agents via Hindsight. Three Tool nodes — Hindsight Retain, Hindsight Recall, Hindsight Reflect — drop into any flow alongside your other LangChain tools.

Why this matters

Flowise is the LangChain-derived visual builder for non-developers and developers alike. Until now, Flowise chatflows have been stateless across sessions. With Hindsight tool nodes you can:

• Retain every closed conversation, support ticket, or form submission into a memory bank
• Recall relevant context before an LLM step so the model sees prior history
• Reflect to ask synthesizing questions ("What do we know about this customer?") inside a flow

Installation

Flowise distributes nodes only inside its main monorepo, so installation today means using a Flowise checkout with the Hindsight nodes copied in. The user-facing distribution will be the upstream PR to FlowiseAI/Flowise.

git clone https://github.com/FlowiseAI/Flowise.git
cd Flowise

# Copy the three tool nodes
cp -r /path/to/hindsight/hindsight-integrations/flowise/nodes/tools/Hindsight* \
  packages/components/nodes/tools/

# Copy the credential class
cp /path/to/hindsight/hindsight-integrations/flowise/credentials/HindsightApi.credential.ts \
  packages/components/credentials/

# Add the client dep
cd packages/components && pnpm add @vectorize-io/hindsight-client
cd ../.. && pnpm install && pnpm build
pnpm start  # opens http://localhost:3000

Setup

Hindsight Cloud (recommended)

Sign up free — no infrastructure to run. Skip straight to creating your credential below.

1. Sign up at Hindsight Cloud (free tier) or self-host
2. Get an API key from the Hindsight dashboard
3. In Flowise, create a new credential of type Hindsight API:
   • API URL — defaults to https://api.hindsight.vectorize.io (Cloud); change for self-hosted
   • API Key — your hsk_... key (optional for self-hosted unauthenticated instances)

Tools

Each Hindsight tool node returns a LangChain DynamicStructuredTool, so it slots into any agent that accepts tools.

Hindsight Retain

Stores content in a memory bank. Hindsight extracts facts asynchronously after the call returns.

Field	Description
Default Bank ID	Memory bank to retain into when the agent doesn't pass one

Tool input schema (the agent passes these): bankId, content, optional tags.

Hindsight Recall

Searches a bank for memories relevant to a query. Returns ranked results.

Field	Description
Default Bank ID	Memory bank to search when the agent doesn't pass one
Default Budget	low / mid / high

Tool input schema: bankId, query, optional budget, maxTokens, tags.

Hindsight Reflect

Returns an LLM-synthesized answer over the bank.

Field	Description
Default Bank ID	Memory bank to reflect on when the agent doesn't pass one
Default Budget	low / mid / high

Tool input schema: bankId, query, optional budget.

Example chatflow

Conversational support agent

1. ChatOpenAI (or any chat LLM)
2. Conversational Agent with three tools attached: Hindsight Retain + Hindsight Recall + Hindsight Reflect, all sharing the same hindsightApi credential
3. Set Default Bank ID to something like user-${sessionId} on each tool
4. The agent learns to call Recall before answering and Retain after meaningful exchanges. Use Reflect for "what do we know about this user?" prompts.
