Like Palantir, but for the Bible. An all-source scripture intelligence terminal. 43+ translation feeds, AI fusion analysts (Talmud · gnosis · gematria · patristic commentary), an Oracle interrogator, and BabelForge — a lab to forge cover-translations of any book in any voice. Air-gap capable. Offline-first PWA. Eyes only.

CODEX is what you'd get if a scripture-obsessed analyst sat down to build an intelligence-grade reader. A terminal, not a website. A station, not an app. Every verse is a target. Every corpus is a feed. The job is to follow the thread.
Open a verse. A column of analysts wakes up — Talmudic parallels, patristic commentary, gematria, Strong's, cross-references, and the Gnostic mirror (Nag Hammadi, Pistis Sophia, Thomas). All feeds, all the time. No paywall, no devotional pablum, no fenced-off canon. The weird stuff is on purpose — Enoch, Jubilees, Meqabyan, the apocalypses — you don't get to study a canon by reading half of it.
Then there's BabelForge — a translation lab. Pick a voice (1611 King James, beat poet, courtroom transcript, 1920s gangster, your bubbe), pick a source, hit forge. The model generates your own AI-translated edition of any book and installs it as a Reader translation alongside KJV. It's your cover-Bible. Make it sound like you.

# open http://localhost:3000 — drop in your API key in Settings to enable AI panels
Or just open the hosted build: https://holasoyneto.github.io/codex
CODEX speaks to five providers — pick whichever you like, mix and match, or run them all. Keys live only in your browser (localStorage) and the optional .env for the local Node server.
- Anthropic Claude (paid, highest quality) — get a key at console.anthropic.com, drop it into Settings → API keys (starts with
sk-ant-…). Best for nuanced exegesis and long contexts. - xAI Grok (paid) — sign up at console.x.ai, paste the
xai-…key. Fast, conversational. - Groq (free, very fast) — different company from xAI's Grok. Free tier at console.groq.com gives you Llama 3.3 70B, DeepSeek R1, Mixtral, and Qwen running on custom LPU silicon. Keys start with
gsk_…. The fastest hosted option per token. - Google Gemini (free, multimodal, 1M tokens/day) — sign up at aistudio.google.com/apikey, paste the key into Settings → API keys. No prefix pattern — just a long alphanumeric string. Best free tier for image + audio inputs (when we expose those).
- Ollama (local, free, private) — install from ollama.com,
ollama pull llama3.2, then start the daemon. CODEX auto-detects it onhttp://localhost:11434. No key, no network — everything runs on your machine.
Single-page React 18 app loaded via CDN with Babel-standalone — there is no build step, no bundler, no node_modules graveyard. Persistence lives in IndexedDB; offline lives in a Service Worker; translations stream from public-domain APIs and cache locally. The plugin system means every companion panel (gematria, Talmud, gnosis, Oracle) is a drop-in JSX module. Fork the repo, open index.html, and you're already running it.
BSD-3-Clause. Take it, ship it, remix it, sell it. Just don't paywall the public domain, and don't slap our name on whatever you remix without asking first.
