+# Hindsight Integration
+
+[Hindsight](https://github.com/vectorize-io/hindsight) is an open-source long-term memory engine for LLM applications. The `hindsight-litellm` package adds persistent, cross-session memory to any of LiteLLM's 100+ providers: relevant memories are injected into your prompts before each call, and conversations are stored back to Hindsight afterward — automatically.
+
+## What is Hindsight?
+
+Hindsight gives your LLM app durable memory across sessions. With the LiteLLM integration you get:
+
+- **Automatic memory injection** — relevant context is retrieved and added to the prompt before each `completion()` call.
+- **Automatic conversation storage** — exchanges are stored back to Hindsight (async by default) so they can be recalled later.
+- **Two retrieval modes** — `recall` (raw memories) or `reflect` (a synthesized, query-focused summary).
+- **Works with every LiteLLM provider** — OpenAI, Anthropic, Azure, Bedrock, Vertex AI, Groq, and more.
+
+It works against [Hindsight Cloud](https://hindsight.vectorize.io) out of the box, or against a self-hosted Hindsight server.
+
+## Prerequisites
+
+```bash
+pip install hindsight-litellm
+```
+
+Get a free API key from [Hindsight Cloud](https://hindsight.vectorize.io), or run Hindsight [locally](https://github.com/vectorize-io/hindsight) and point at `http://localhost:8888`.
+
+## Quick Start
+
+`hindsight-litellm` wraps `litellm.completion`, so once it's enabled you keep calling LiteLLM exactly as before — memory injection and storage happen transparently.
+
+<Tabs>
+<TabItem value="cloud" label="Hindsight Cloud">
+
+```python
+import os
+import litellm
+import hindsight_litellm
+
+os.environ["OPENAI_API_KEY"] = "your-openai-key"
+
+# 1. Configure Hindsight (defaults to Hindsight Cloud)
+hindsight_litellm.configure(
+    api_key=os.environ["HINDSIGHT_API_KEY"],  # from https://hindsight.vectorize.io
+)
+
+# 2. Set the memory bank to read/write
+hindsight_litellm.set_defaults(
+    bank_id="my-agent",
+    use_reflect=True,  # synthesize a focused context summary
+)
+
+# 3. Enable the integration (patches litellm.completion / acompletion)
+hindsight_litellm.enable()
+
+# 4. Use LiteLLM as normal — memory is injected and stored automatically
+response = litellm.completion(
+    model="gpt-4o-mini",
+    messages=[{"role": "user", "content": "What did we decide about the database?"}],
+    hindsight_query="database decisions",  # what to search memory for
+)
+
+print(response.choices[0].message.content)
+```
+
+</TabItem>
+<TabItem value="selfhosted" label="Self-Hosted">
+
+```python
+import os
+import litellm
+import hindsight_litellm
+
+os.environ["OPENAI_API_KEY"] = "your-openai-key"
+
+# Point at your own Hindsight server instead of Hindsight Cloud
+hindsight_litellm.configure(
+    hindsight_api_url="http://localhost:8888",
+)
+
+hindsight_litellm.set_defaults(
+    bank_id="my-agent",
+    use_reflect=True,
+)
+
+hindsight_litellm.enable()
+
+response = litellm.completion(
+    model="gpt-4o-mini",
+    messages=[{"role": "user", "content": "What did we decide about the database?"}],
+    hindsight_query="database decisions",
+)
+
+print(response.choices[0].message.content)
+```
+
+</TabItem>
+</Tabs>
+
+:::info
+When `inject_memories` is enabled (the default), pass `hindsight_query` on each call to tell Hindsight what to search memory for. This keeps retrieval intentional and focused.
+:::
+
+## Memory Modes
+
+Choose how retrieved memory is added to the prompt with `use_reflect`:
+
+<Tabs>
+<TabItem value="reflect" label="reflect (synthesized)">
+
+`reflect` asks Hindsight to synthesize a single, query-focused summary from the
+underlying memories — useful when you want compact, reasoned context.
+
+```python
+hindsight_litellm.set_defaults(
+    bank_id="my-agent",
+    use_reflect=True,
+    reflect_context="I am a support agent helping a returning customer.",
+)
+```
+
+</TabItem>
+<TabItem value="recall" label="recall (raw)">
+
+`recall` injects the raw matching memories — useful when you want the model to
+see the individual facts.
+
+```python
+hindsight_litellm.set_defaults(
+    bank_id="my-agent",
+    use_reflect=False,
+    max_memories=10,
+    fact_types=["world", "opinion"],
+)
+```
+
+</TabItem>
+</Tabs>
+
+## Per-Call Overrides
+
+Any default set via `set_defaults()` can be overridden on an individual call
+using `hindsight_*` keyword arguments:
+
+```python
+response = litellm.completion(
+    model="gpt-4o-mini",
+    messages=[{"role": "user", "content": "Where is Alice now?"}],
+    hindsight_query="Alice's current location",          # required when inject_memories=True
+    hindsight_reflect_context="The team is mid-incident", # per-call reflect context
+    hindsight_bank_id="ops-team",                         # override the bank for this call
+)
+```
+
+## How It Works
+
+```
+completion(query) ──► recall/reflect from Hindsight ──► inject into prompt
+                                                              │
+                                                              ▼
+                              LLM call (any LiteLLM provider)
+                                                              │
+                            store conversation to Hindsight ◄─┘
+                                                              │
+                                                              ▼
+                                                   response returned
+```
+
+1. You call `litellm.completion(...)` with a `hindsight_query`.
+2. Hindsight retrieves relevant memory (raw via `recall`, or synthesized via `reflect`).
+3. The memory is injected into the prompt (system message by default).
+4. The enriched request is sent to your chosen LiteLLM provider.
+5. The conversation is stored back to Hindsight (async by default) for future recall.
+6. You get the response back exactly as a normal LiteLLM call.
+
+## Configuration Reference
+
+| Function | Key settings |
+| --- | --- |
+| `configure()` | `hindsight_api_url`, `api_key`, `inject_memories`, `store_conversations`, `sync_storage`, `injection_mode`, `excluded_models`, `verbose` |
+| `set_defaults()` | `bank_id` (required), `use_reflect`, `budget`, `fact_types`, `max_memories`, `max_memory_tokens`, `reflect_context`, `document_id` |
+| Per-call `hindsight_*` kwargs | `hindsight_query` (required when injecting), plus overrides for any default above |
+
+See the [package README](https://github.com/vectorize-io/hindsight/tree/main/hindsight-integrations/litellm) for the full option list.
+
+## Direct SDK without `enable()`
+
+If you prefer not to patch `litellm.completion` globally, call the wrapper
+directly — it has the same signature as `litellm.completion`:
+
+```python
+import hindsight_litellm
+
+hindsight_litellm.configure(api_key=os.environ["HINDSIGHT_API_KEY"])
+hindsight_litellm.set_defaults(bank_id="my-agent", use_reflect=True)
+
+response = hindsight_litellm.completion(
+    model="gpt-4o-mini",
+    messages=[{"role": "user", "content": "Catch me up."}],
+    hindsight_query="recent project status",
+)
+```
