What Unstract is
Unstract extracts structured data from unstructured documents and automates document workflows. Prompt Studio uses natural-language instructions to define extraction projects that can be deployed as APIs or ETL pipelines. Agentic Prompt Studio uses multi-agent pipelines to define schemas, create prompts, and validate extraction across documents. Unstract describes itself as document agnostic and says it works without prior training or templates. Human-in-the-loop workflows can route selected documents for review, approval, and validation. LLMChallenge uses two language models to challenge extracted responses; SinglePass and Summarized Extraction are described as ways to reduce token use. Integrations include Anthropic, OpenAI, and Vertex AI models, plus file systems and databases such as Azure Cloud Storage, PostgreSQL, and S3/Minio. Deployment options include managed cloud, on-premise enterprise, and open-source self-hosted editions. The pricing page says cloud data is encrypted in transit and at rest and is not used for training. The Open Source plan is free and limited to one self-hosted user. Starter (monthly) costs $499 a month, billed monthly, and includes 5,000 pages per month with a $0.10 per-page overage.
