Technical Overview

You've seen what Quira does. Now let's look at how it's built. Quira is structured in three primary layers, all running locally on your machine:

• UI Layer (Rust + WebGPU)  ENative-performance interface including the Graph Explorer, Space Bar, and all custom UI elements.
• Context Layer (SQLite + FTS5 + sqlite-vec)  EThe local graph database that stores and indexes all Context Graph data.
• Agent Layer (llama.cpp / MLX)  EThe local LLM runtime that powers summarization, entity extraction, embedding generation, and NL Query.

All three layers sit on top of the Gecko-based rendering engine, which handles standard web page rendering and provides full WebExtension API compatibility.
