Claix - 2026 Pricing, Features, Reviews & Alternatives

Claix is an AI Data Processing API built for traditional systems and autonomous AI agents. We transform unstructured documents (PDFs, Excels, Word, images) into strict, type-safe JSON payloads in a single API call.

The Problem We Solve

Extracting data from documents usually means choosing between fragile OCR templates that break when layouts change, or raw LLMs that hallucinate and suffer from "schema drift." Both approaches create unreliable data pipelines that break backend automations and fail autonomous AI agents.

The Claix Solution: Schema-Driven Inference

Claix acts as an intelligent data processing middleware. You simply define a strict JSON schema with your required fields and semantic rules. Claix analyzes the document, handles direct data mapping, and evaluates complex semantic logic in a single pass—returning deterministic JSON ready for your database.

Agent Mode & Semantic Reasoning

Claix goes beyond standard data extraction. With our Agent Mode, you can embed custom logic directly into your schema. Want to know if a legal contract includes a specific penalty clause? Or if an invoice has a late fee? Simply define the rule, and Claix infers the answer from the document, returning a strictly typed response (booleans, arrays, strings). Give your systems deterministic data and your AI agents structured reasoning without parsing unpredictable free-text LLM responses.

Who is it for?

Backend developers, automation engineers, and AI founders who need to build reliable document extraction pipelines for legacy software or feed deterministic, structured data into autonomous AI agents.
