+## Q: How does Claude Context compare to other coding tools like Serena, Context7, or DeepWiki?
+
+**A:** Claude Context is specifically focused on **codebase indexing and semantic search**. Here's how we compare:
+
+- **[Serena](https://github.com/oraios/serena)**: A comprehensive coding agent toolkit with language server integration and symbolic code understanding. Provides broader AI coding capabilities.
+
+- **[Context7](https://github.com/upstash/context7)**: Focuses on providing up-to-date documentation and code examples to prevent "code hallucination" in LLMs. Targets documentation accuracy.
+
+- **[DeepWiki](https://docs.devin.ai/work-with-devin/deepwiki-mcp)**: Generates interactive documentation from GitHub repositories. Creates documentation from code.
+
+**Our focus**: Making your entire codebase searchable and contextually available to AI assistants through efficient vector-based indexing and hybrid search.
