Expanded Capacity

A local knowledge base with full-text search.

Expanded Capacity is a Gemini NotebookLM-style local Retrieval-Augmented Generation system backed by a dedicated SQLite database with FTS5 full-text search. Drag and drop Markdown (.md) and text (.txt) files into notebook cards for previewing, referencing, and on-demand retrieval by the AI agent.

Key capabilities

• SQLite FTS5 virtual table with automatic triggers for real-time indexing
• Drag-and-drop or batch file upload for .md and .txt documents
• Card-based UI with metadata badges - type, size, word count, timestamps
• Agent queries the knowledge base via retrieve_expanded_capacity skill
• WAL mode for fast concurrent reads without blocking writes
