One File In. Many Documents Out

Automatically split and classify mixed document streams — no manual sorting, no preprocessing, no guesswork.

Messy Inputs Break Automation

You don’t control what gets uploaded — your users do.

Most document workflows don’t start with a single, perfectly labeled file. In reality, your customers or end users are the ones uploading documents — and they upload whatever they have.

That usually means:

  • Bundled PDFs containing multiple documents

  • Mixed document types from different sources

Before any extraction can happen, teams are forced to manually split, classify, and route documents — slowing down workflows and introducing errors.

Automatic Separation. Intelligent Identification.

Invofox handles messy, user-generated uploads the way production systems need to.

Invofox combines Splitter and Classifier to automatically separate, identify, and route documents — even when everything arrives bundled together.

No preprocessing. No manual sorting. No rigid upload rules.

How Teams Use Splitter + Classifier in Production

One uploaded file. Many document types. Fully automated processing.

Ingest files
1
Upload single PDFs or batched files containing multiple documents.
Detect document boundaries
2
Splitter uses AI-trained models to analyze page structure and identify where each document begins and ends, even when layouts are inconsistent or unknown.
Split the file into individual documents
3
Once boundaries are detected, the file is split and new PDF files are generated, with each resulting document processed as an independent unit.
Classify each document
4
Classifier uses AI-trained models to automatically identify document types based on content, layout, and the data that needs to be extracted.
Route to the right workflow
5
Each document is processed using the appropriate extraction and validation logic.

All splitting and classification results — including document IDs and page ranges for each document — are returned via the API, giving your system full visibility into how each uploaded file was processed.

Review our Splitter and Classifier developer documentation

In real workflows, a single uploaded file may contain multiple document types bundled together.

For example, one file might include: Loan or mortgage documents, multiple payslips, an invoice or a bill of lading.

Splitter separates each document, and Classifier identifies each document type — automatically routing every document to the correct extraction workflow.

Split. Classify. Extract. Route.

Splitter

Automatically separates multi-document files into individual documents, even when files are unstructured or not consistently formatted.

Classifier

Identifies document types for each document independently, eliminating manual labeling and fragile upload rules.

Extraction

Extracts the required data from each document using the appropriate extraction logic based on document type.

Routing

Route extracted data to the correct downstream workflow or system, without changing how users upload files.

Everything needed to automate mixed file uploads.

Automate Document Routing at Scale

Stop fixing documents before you can process them.
