## 🔥 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
```bash
pip install quira
```

### Usage
```python
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
```python
# 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:

<table>
<tr>
<td width="50%">

### 🏎️ 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.

</td>
<td width="50%">

### 🧩 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.

</td>
</tr>
<tr>
<td width="50%">

### 🔄 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.

</td>
<td width="50%">

### 📄 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.

</td>
</tr>
</table>
