# ConjunctionReservoir Document Chat

Github is at: https://github.com/anttiluode/conjunctionreservoir 

Upload any `.txt` or `.pdf` document and chat with it.

**What makes this different from standard RAG:**

Instead of asking *"do query terms appear somewhere in this chunk?"*, ConjunctionReservoir asks *"do query terms appear in the **same sentence**?"*

This is grounded in auditory neuroscience:
- **Norman-Haignere et al. (2025):** auditory cortex integration windows are time-yoked (~80ms fixed clocks)
- **NMDA receptor logic:** hard AND gate — both inputs must arrive simultaneously
- **Vollan et al. (2025):** coverage-maximizing theta sweep for exploration

**Benchmark:** 100% Rank-1 rate on conjunction queries vs 60% for BM25 and SweepBrain.

## Usage

1. Upload a `.txt` or `.pdf`, or paste text directly
2. Ask questions — works best for queries requiring two concepts together
3. Adjust the **conjunction threshold** slider to tune precision vs recall
4. Use `:coverage`, `:summary`, `:threshold N` commands in chat

## No dependencies beyond NumPy for retrieval. Generation via HuggingFace Inference API (free).
