+# Memory (LanceDB) Extension
+
+LanceDB-backed long-term memory with semantic search.
+
+## Venice Embeddings (New!)
+
+Uncensored embeddings w/o OpenAI key:
+
+```json
+{
+  \"extensions\": {
+    \"memory-lancedb\": {
+      \"embedding\": {
+        \"provider\": \"venice\",
+        \"model\": \"text-embedding-bge-m3\",
+        \"apiKey\": \"VENICE-INFERENCE-KEY-...\",
+        \"baseUrl\": \"https://api.venice.ai/api/v1\"
+      },
+      \"autoCapture\": true,
+      \"autoRecall\": true
+    }
+  }
+}
+```
+
+- **Model**: text-embedding-bge-m3 (1024 dims)
+- **Compatible**: OpenAI client proxy
+- **Fallback**: OpenAI text-embedding-3-small/large
+
+## Setup
+
+1. Add to Clawdbot config.
+2. `clawdbot gateway restart`
+3. Use `memory_search \"query\"` – works!
+
+## Tools
+
+- `memory_search`: Semantic recall from MEMORY.md + memory/*.md
+- `memory_get`: Snippet read
+- Auto-capture/recall on conversations
