## Turn real estate documents into faster closings

- **Detect Signatures Reliably** — Leases are full of signature blocks scattered across dozens of pages. Detect signed, unsigned, and partially executed fields across any format.
- **Split Addendums and Disclosures Automatically** — PSAs come bundled with dozens of attachments. Split out each document type, even when mid-page, to ensure relevant extraction.
- **Know Exactly When to Trust the Output** — Deeds contain critical legal details: grantors, legal descriptions, parcel IDs. Confidence scores on every field, with automatic flagging for human review.
- **Handle Every County's Format** — Tax statements vary wildly by jurisdiction. Extract assessed values, tax amounts, and parcel info regardless of each municipal format.
- **Fill Forms Dynamically** — Edit seller disclosures, closing docs, and transfer forms by mapping your data to detected fields automatically.

## The highest performance document APIs for your agents and pipelines. Processing millions of pages every day.

APIs:

### 01 / parse

Convert unstructured documents into context for agents.

- **Layout detection** — Advanced layout model detects tables, checkboxes, images, handwriting, and signatures on every page.
- **Specialized vision models** — A hybrid computer vision + vision-language model pipeline routes each element to purpose-built models.
- **Multiple performance modes** — Toggle between performance modes optimized for speed, cost, or accuracy.
- **Handle every file** — 25 file types, 100+ languages, and 4 chunking strategies — all through one API.

### 02 / extract

Extract structured data from documents into any schema.

- **Scale to 1,000+ page files** — Smart chunking & merging strategies ensure accurate extraction without hitting token output or context limits.
- **Extract large tables** — Choose from multiple array extraction strategies, capable of extracting 1,000+ rows accurately across 100s of pages.
- **Precise bounding boxes** — Dedicated citation model generates granular citations for every extracted value, even inferred ones.
- **Low latency processing** — Fast mode extraction for real-time use cases.
- **Model-agnostic by design** — New foundation models are continuously benchmarked and integrated. Evaluate performance and upgrade versions safely.

### 03 / split

Segment multi-document files into individual subdocuments.

- **Large document splitting** — High-precision splitting that maintains accuracy on 2,000+ page files.
- **Instance detection** — Detect unique identifiers to separate multiple instances of the same document type, like splitting 50 invoices by invoice number.
- **Intelligent boundary handling** — Smart overlap handles mid-page boundaries while keeping context intact.
- **Cost-optimized splitting** — Toggle cost-optimized splitting for bulk jobs, or high precision for tough files.

### 04 / classify

Classify documents into pre-defined categories.

- **Optimized for cost** — Deploy fast and cheap classification at scale with purpose-built classifiers, without compromising on accuracy.
- **Memory** — Multimodal retrieval system that learns from past examples to handle edge cases where prompting falls short.
- **Real time classification** — Toggle low-latency classification to give instant feedback to your users.

### 05 / edit

Detect form fields and fill them programatically.

- **Comprehensive field support** — Detect and fill in checkboxes, signatures, text fields, tables, dropdowns, multi-line paragraphs, and character-per-box inputs (like SSNs).
- **Dynamic form filling for agents** — Use natural language instructions to map data to the right fields automatically, no template required.
- **Template-based filling** — For static forms, detect field positions once and fill them at scale deterministically.
- **Reliability at any scale** — Fast, reliable results even on complex forms with hundreds of fields.
