+# Go Memory-Augmented API
+
+
+:::info Complete Application
+This is a complete, runnable application demonstrating Hindsight integration.
+[**View source on GitHub →**](https://github.com/vectorize-io/hindsight-cookbook/tree/main/applications/go-memory-service)
+:::
+
+
+A Go HTTP microservice demonstrating per-user memory isolation with Hindsight. Remembers each user's tech stack, problems solved, and preferences to provide personalized assistance.
+
+## Features
+
+- 🔐 **Per-User Isolation**: Each user gets their own memory bank
+- 🧠 **Context-Aware Responses**: Uses recall + reflect for personalized answers
+- 🏃 **Fire-and-Forget Memory**: Background goroutines store interactions without blocking responses
+- 🏷️ **Tag-Based Partitioning**: Organize memories by type (projects, debugging, preferences)
+
+## Setup
+
+### 1. Start Hindsight
+
+```bash
+export OPENAI_API_KEY=your-key
+
+docker run --rm -it --pull always -p 8888:8888 -p 9999:9999 \
+  -e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
+  -e HINDSIGHT_API_LLM_MODEL=o3-mini \
+  -v $HOME/.hindsight-docker:/home/hindsight/.pg0 \
+  ghcr.io/vectorize-io/hindsight:latest
+```
+
+### 2. Run the service
+
+```bash
+go run main.go
+```
+
+### 3. Try it out
+
+```bash
+# Store memories
+curl -s localhost:8080/learn -d '{
+  "user_id": "alice",
+  "content": "I am building a Go microservice with gRPC and PostgreSQL",
+  "tags": ["project"]
+}'
+
+curl -s localhost:8080/learn -d '{
+  "user_id": "alice",
+  "content": "I prefer structured logging with slog over zerolog",
+  "tags": ["preferences"]
+}'
+
+# Ask questions (uses recall + reflect)
+curl -s localhost:8080/ask -d '{
+  "user_id": "alice",
+  "query": "What tech stack am I using?"
+}' | jq .
+
+# Raw memory recall
+curl -s "localhost:8080/recall/alice?q=database" | jq .
+```
+
+## API Endpoints
+
+- `POST /learn` - Store new information for a user
+- `POST /ask` - Ask a question using the user's memories
+- `GET /recall/{userID}?q=query` - Direct memory recall
+- `GET /health` - Health check
+
+## Key Patterns
+
+**Per-User Banks**: Each user gets an isolated memory bank (`user-alice`, `user-bob`)
+
+**Async Memory Storage**: Interactions are stored in background goroutines:
+
+```go
+go func() {
+    bgCtx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+    defer cancel()
+
+    retainReq := hindsight.RetainRequest{
+        Items: []hindsight.MemoryItem{{
+            Content: interaction,
+            Context: *hindsight.NewNullableString(hindsight.PtrString("Q&A interaction")),
+        }},
+    }
+    client.MemoryAPI.RetainMemories(bgCtx, bankID).RetainRequest(retainReq).Execute()
+}()
+```
+
+**Tag-Based Filtering**: Partition memories within a bank by type for scoped retrieval
