🔥 The Problem

Traditional RAG is slow and wasteful:

User types query → Hits Enter → WAIT → Vector search → WAIT → Stuff 10 chunks → WAIT → LLM response
                                 ⏱️ 1.5s avg latency, 65% of context is noise

✨ The Quira Solution

Quira predicts what users need before they finish typing, compresses context to maximize density, and tracks conversation state to eliminate redundant fetches:

User starts typing → Quira searches speculatively → User hits Enter → Context already cached!
                     → Differential fetch (only new chunks) → Context Tetris (compress + score)
                                 ⏱️ 210ms avg latency, 94% context density

📦 Quickstart

Install

pip install quira

Usage

import asyncio
from quira import quiraPipeline, UserSession

async def main():
    # Initialize with your own clients
    pipeline = quiraPipeline(
        qdrant_client=qdrant,
        redis_client=redis,
        groq_client=groq,
        embed_func=my_embed_func,
        spacy_model=my_spacy_model
    )

    session = UserSession(user_id="user_123")

    # 🏎️ Speculative fetch while user types
    await pipeline.handle_typing_event(session, "What is the re")

    # 🎯 Submit — context is already warm!
    answer = await pipeline.process_submission(
        session, "What is the return policy?"
    )
    print(answer)

asyncio.run(main())

Ingest PDFs

# Parse, chunk, embed, and store — one line.
chunks = await pipeline.ingestor.ingest_pdf("user_123", "docs/return_policy.pdf")
print(f"Indexed {chunks} chunks into Qdrant")

⚙️ How It Works

Quira is built on 4 core modules that work together as a unified pipeline:

🏎️ Module 1 — Speculative Retrieval Listens to user keystrokes via WebSocket. Uses adaptive debouncing (250ms–600ms based on typing speed) to fire Qdrant searches before the user submits. Results are cached in Redis with SHA-256 hashed keys.	🧩 Module 2 — Context Tetris Scores every chunk on 4 dimensions: Relevance, Recency, Uniqueness, and Density. Uses Groq LLM to compress filler text. Orders chunks in a U-shape (best chunks at start and end) to combat "Lost in the Middle" syndrome.
🔄 Module 3 — Differential Retrieval Maintains a stateful Context Pool across conversation turns. Measures cosine similarity between consecutive queries. If similarity > 0.6, fetches only delta chunks. Garbage-collects stale context when topics shift.	📄 Module 4 — Document Ingestion Parses PDFs with PyMuPDF. Splits text into overlapping chunks (1000 chars / 200 overlap by default) to prevent sentence fragmentation. Generates embeddings and upserts directly into Qdrant.
