AI data extraction from PDF financial statements and complex documents.
Pull structured figures out of balance sheets, income statements and cash flow statements with accounting-grade accuracy.
Capture data from bank statements, invoices, contracts, trade finance documents and identity documents like passports and driving licences.
Point-and-click to define the data points you want; no rule writing or coding required.
Users correct errors and the system learns, so accuracy improves on your specific document styles over time.

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.
