Dify

Persistent memory for Dify workflows via Hindsight. The Hindsight Dify plugin adds three tools — Retain, Recall, Reflect — that work alongside any other Dify node in workflows, chatflows, and agent apps.

Why this matters​

Dify is one of the most popular open-source LLM app platforms — visual workflow builder, prompt management, and a growing tool/plugin ecosystem. Until now, Dify workflows have been stateless across runs. With Hindsight tools you can:

• Retain every closed support ticket, sales-call transcript, 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 workflow

Installation​

In your Dify dashboard go to Plugins → Install Plugin, then choose one of:

• Marketplace — search for Hindsight (once published)
• GitHub — install from vectorize-io/hindsight (path hindsight-integrations/dify)
• Local — upload the .difypkg archive

After install, the Hindsight plugin appears under Tools in the workflow editor.

Setup​

1. Sign up at Hindsight Cloud (free tier) or self-host
2. Get an API key from the Hindsight dashboard
3. In Dify, open the Hindsight plugin and add credentials:
   • 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​

Retain​

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

Recall​

Search a bank for memories relevant to a query. Returns a results array.

Reflect​

Get an LLM-synthesized answer over the bank. Returns text.

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/Anthropic 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.

Knowledge-base agent — every uploaded document is chunked and retained. The Dify chatflow uses Recall instead of vector-DB-only retrieval, getting fact-extracted, deduplicated, time-aware results.
