aityx

aityx is a decision API for AI applications that processes data and returns typed answers with calculated amounts and dates.

aityx is a decision API for artificial intelligence applications that handles complex calculations like amounts and dates alongside typed answers. It combines interpretation and execution in one call when necessary, allowing applications to use structured data directly in code. Users can start with prompts, PDFs, spreadsheets, Word documents, images, or text files to build decision models with an integrated assistant or their own tools. System One executes models using structured facts, while System Two interprets unstructured input first before execution. The platform is built by Aletyx for developers seeking programmatic decision-making capabilities.
