# Nutrient — The deterministic document platform

> SDKs, cloud APIs, and workflow agents for document work that can't run on a guess. Nutrient turns messy, high-stakes documents into structured, auditable data, and powers high-fidelity viewing, editing, generation, conversion, OCR, redaction, and eSignatures across web, mobile, and server. Deterministic by design: same output every run, confidence scores, and clear exceptions where AI is involved. Deploy in the cloud, self-hosted, or air-gapped. Use any AI model, your own, or none.

## How to navigate this site

- **Per-SDK guides indexes** live at `/guides/<sdk>/llms.txt` — each lists the topic indexes available for that SDK.
- **Per-SDK API references** live at `/api/<sdk>/llms.txt` — same shape, for the SDK’s API surface.
- Each per-SDK index points at **per-topic sub-indexes** named `/guides/<sdk>/llms-<topic>.txt` (and the matching `/api/<sdk>/llms-<topic>.txt`). Available topics vary per SDK — fetch the per-SDK index to see what each SDK covers. Topic URLs that aren’t listed in a per-SDK index do not resolve (404), so the per-SDK index is the authoritative signal of available topics for that SDK.
- For **bulk content ingestion**, see [/llms-full.txt](/llms-full.txt).
