+## Dendrite Integration
+
+Symbiont has web perception via **Dendrite**, a headless Chromium browser running on cortex as a Docker service.
+
+### Quick access from Symbiont code
+
+```python
+from symbiont.web import fetch_page, take_screenshot, search_web
+
+# Fetch and read a webpage
+page = fetch_page("https://example.com")
+print(page['title'], page['content'][:200])
+
+# Screenshot for visual verification  
+png = take_screenshot("https://example.com")
+
+# Multi-step: search and read results
+results = search_web("best python async frameworks 2026")
+```
+
