Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.

OCR and multi-modal document extraction APIs with built-in fraud detection
Multi-modal OCR APIs extract structured fields from invoices, receipts, bank statements, checks, W-2s, insurance cards and 100+ other document types with day-one accuracy.
Every document receives a fraud verdict with a color, a score and reasons returned under meta.fraud, covering AI-generated fakes, edited pixels, math mismatches, duplicate submissions and edited PDF layers and metadata.
Mobile (iOS and Android) and browser camera frameworks plus wrapper support and secure credit-card capture deliver clean, correctly cropped images before any API call.
Document classification and routing, PDF splitting, product/SKU-level intelligence and document-to-Markdown conversion are available as add-ons alongside the core OCR pipeline.
