Prompt Studio: Prompt Engineering Interface for Document Processing

Turn any document into structured data in minutes

Extract structured data from any document using Natural Language, with unparalleled accuracy and cost-efficiency.

Trusted by organizations that demand precision and scale

Your IDE can’t handle professional prompt engineering

The reality today

Writing prompts with standard IDE is slow and fragmented.

You're constantly switching between sample documents, prompt text files, and terminals.
Testing against document variations is done manually, and enforcing a consistent output schema means writing and maintaining complex logic.

On-demand intelligence

Instantly extract the data you need from any document.

Iterate quickly with prompts, documents, and outputs all in one view.
Test prompts against documents simultaneously.
Enforce any output type with a simple toggle.
Deploy projects as a production-ready API or ETL pipeline.

A purpose-built prompt engineering environment

Unstract transforms every document into structured data that flows through your infrastructure. Deploy outputs the way you want: lightweight APIs or enterprise ETL.

Build and test prompts within a single canvas

Write prompts for any use case—from line items on an invoice to clauses in a legal contract—and see instant results. And refine them on the fly without writing a single line of code.

Spot and discard hallucinations quickly

Run prompts through 2 different models at the same time with LLMChallenge and get an output only if both agree. Eliminate hallucinations and bring the highest level of trust for outputs.

Control LLM Costs with token-saving toggles

Prompt Studio helps you keep LLM costs down with SinglePass and Summarized extraction. Both modes let you balance speed and cost to reduce token usage by up to 7x.

Enforce consistent schema for any input

Obtain the exact data structure you need—from simple text to nested JSON—and transform arbitrary inputs from any document into clean, reliable, and system-ready data.

View the exact source of extracted results

Instantly verify outputs with Source Document Highlighting to make reviews faster, ensure a completely auditable trail and build absolute trust in your automated workflows.

Ensure consistent and reliable extraction every time

View how prompts perform across documents with Prompt Coverage and quickly optimize underperforming ones to simplify cross-document verification and quality assurance processes.

Get unprecedented control

Go beyond basic prompting with a full suite of advanced controls built for accuracy and workflow efficiency.

Output Analyzer

Compare source documents to the extracted data and make changes on the go.

Preamble and Postamble

Use preambles to guide the LLM’s approach before each prompt, and Postambles to format the final output.

Combined Output

Consolidate the results from all your prompts into a single, structured JSON object.

Clone, Share, & Export

Start new projects quickly or share it with your team in read-only mode, even if they don’t have an Unstract account.

Unstract lets us turn a wide range of document formats into clean, structured data with low integration effort and without compromising on enterprise-grade controls. Its high extraction accuracy paired with clear highlight-based validation speeds up our process a lot!
