DRACO — The Book-Forged Code Oracle

Other AIs guess. DRACO knows — and proves it.

DRACO answers coding, systems, and security questions using retrieval over a library of 1,855 real technical books (354M characters, 116,558 indexed passages) — and cites the exact book behind every claim. No knowledge cutoff. No hallucination laundering. Receipts attached.

Why it's different

Generic chatbot	DRACO
Compressed training-data recall	Live retrieval from 1,855 books on the shelf
"Trust me" answers	Every claim carries `[n]` citations + a `sources` array
Knowledge cutoff: yes	The canon is resident — K&R, Tanenbaum, the shellcoders' handbook
Sells your prompts	Self-hosted, zero telemetry, questions never leave the house

Quickstart

Chat in the browser

https://draco.thetempleofdoom.com — streaming answers, visible reasoning, sources bar under every response. 10 free/day, no account.

REST API

# 1. Get a free key (30 credits/month, email only, no card)
curl -s -X POST https://draco.thetempleofdoom.com/api/signup \
  -H 'Content-Type: application/json' \
  -d '{"email":"you@domain.tld"}'
# → {"api_key":"sk-draco-..."}

# 2. Ask — RAG-grounded answer with citations (1 credit)
curl -s -X POST https://draco.thetempleofdoom.com/api/ask \
  -H 'X-API-Key: sk-draco-...' -H 'Content-Type: application/json' \
  -d '{"q":"explain the ret2libc technique with a minimal poc"}'
# → {"answer":"...[1]...[2]","sources":[{"title":"...","category":"..."}]}

# 3. Raw passage search across all 1,855 books (1 credit)
curl -s "https://draco.thetempleofdoom.com/api/search?q=tcp%20syn%20flood&k=5" \

Tools:

draco_ask(question) → cited, book-grounded answer
draco_search(query, k) → raw BM25 passages with titles + scores
draco_status() → live library stats

How it works

question ──► BM25 retrieval over 116k book passages
                │
                ▼
        top passages + question ──► local LLM (self-hosted GPU)
                │
                ▼
        answer with inline [n] citations + sources array

Ingest (ingest.py) — PDF/CHM/DJVU → clean plain text. Junk scans dropped automatically.
Index (build_index.py) — 300-token overlapping chunks → Snowball-stemmed BM25 index.
Serve (Flask + gunicorn) — retrieval-augmented generation with SSE streaming, separate reasoning and answer channels, and automatic degenerate-output detection/retry.
Expose — REST API, streamable-http MCP server, and a full agent-discovery kit: /llms.txt, /llms-full.txt, /openapi.json, /.well-known/ai-plugin.json, /.well-known/mcp-server.json, /sitemap.xml.

Pricing

Bitcoin only. No subscription traps, no KYC, no card processor.

Tier	Price	What you get
Web (no key)	free	10 questions/day in the browser
API key	free	30 credits/month, forever
satchel	$3	60 credits
crate	$10	250 credits
hoard pack	$25	750 credits
HOARD	$50/mo	unlimited — every ask, every search, 30 days

1 credit = 1 ask or 1 search. Credits never expire. Books are free to download at /library — we sell answers, not files.

Self-hosting

git clone https://github.com/drjonesxxx1/draco.git
cd draco
python3 -m venv venv && ./venv/bin/pip install -r requirements.txt
cp config.example.json config.json   # set model, ollama URL, limits, payments

# point ingest.py at YOUR book directory, then:
./venv/bin/python3 ingest.py         # books → text + manifest
./venv/bin/python3 build_index.py    # text → BM25 index

./venv/bin/gunicorn -w 2 --threads 8 -b 127.0.0.1:8012 app:app    # API + web
./venv/bin/python3 -m uvicorn mcp_server:app --port 8013           # MCP

Any local Ollama model works. Put nginx in front (see deploy/nginx-draco.conf for the reference config incl. SSE + MCP proxying). Payments are optional — leave the btcpay block empty and the free tiers carry the whole thing.
