Agentic Prompt Studio: Introduction

Beta Notice

Agentic Prompt Studio is currently in beta. Features and behavior may change as the product evolves.

Introduction​

Setting up reliable document extraction is harder than it looks. The documents themselves arrive as PDFs, scans, or digital files. The hard part is everything that comes after.

First, you need to define a schema: what fields exist in these documents, their data types, which ones are required, and how they nest.

For a single document variant, this is manageable.

But real-world document sets — credit card statements from five different issuers, invoices from dozens of vendors, contracts with varying clause structures — contain the same information labeled and formatted differently across every variant. Building a schema that accounts for all of these variations requires analyzing each variant, recognizing which fields are equivalent despite different names, and consolidating everything into a single coherent structure.

This typically takes hours to days of manual work, and the risk of overlooking fields that only appear in certain variants is high.

Next, you need to write an extraction prompt that tells the LLM exactly how to pull structured data from these documents. A generic prompt produces generic results. An effective prompt needs to account for the specific patterns, anchors, formatting conventions, and edge cases present in your document set — like where dates appear, how amounts are formatted, what to do when a field is missing, how to handle multi-line values.

Writing this prompt well requires deep familiarity with both the documents and the schema, and getting it right usually involves multiple rounds of trial and error.

Finally, once the prompt works, you need a way to know it keeps working. Every prompt edit carries the risk of fixing one field while silently breaking another. Without a systematic way to compare extraction results against known-correct baselines, regressions go undetected until they surface in production.

Agentic Prompt Studio addresses each of these challenges.

It uses multi-agent AI pipelines to automate schema generation, prompt creation, and accuracy tracking — replacing days of manual iteration with minutes of automated analysis, while keeping you in full control to review, edit, and refine every output.

Capabilities​

Agentic Prompt Studio has three core capabilities:

  • Agentic Schema Generation. Analyzes your document samples and produces a production-ready JSON Schema. It handles field normalization across document variants, determines data types, and identifies nested structures.
  • Agentic Extraction Prompt Generation. Crafts a detailed, versioned extraction prompt tailored to your documents' specific patterns and formatting.
  • Verification Sets and Accuracy Tracking. Lets you maintain manually verified extraction data per document, then compares new extraction results against those baselines to catch regressions and quantify improvements.

Architecture​

Agentic Prompt Studio is organized into two agent pipelines and a set of extraction and comparison services:

End-to-End Data Flow​

The complete processing pipeline moves through 6 stages:

  1. Document Upload: Documents are processed through LLMWhisperer, which extracts raw text with line metadata.
  2. Schema Generation: The SummarizerAgent, UniformerAgent, and FinalizerAgent produce a JSON Schema.
  3. Prompt Generation: The PatternMinerAgent, PromptArchitectAgent, and CriticDryRunner produce an extraction prompt.
  4. Data Extraction: The ExtractionService runs the prompt against documents, producing structured JSON with source references.
  5. Highlight Mapping: The HighlightService maps extracted values back to coordinates in the original PDF.
  6. Result Verification: Users review results, the ComparisonService calculates accuracy metrics.
