Chart

As an API for income verification, Chart is narrower than most document extraction tools: it focuses on tax records for fintechs.

Chart is an AI document extraction API that pulls documents from the IRS and leading tax software, runs OCR on them, and returns clean, structured JSON for income verification and client onboarding.

Developers get a REST API with SDKs, sandbox environments and documentation.

Chart can also package your models into C++ servers and deploy them inside your own cloud account, which matters if you need to keep data and infrastructure under your control.

More than one integration method is available, and support is high-touch.

The tradeoff is scope.

Chart is built for fintech teams handling tax documents, not for general-purpose data extraction from any file type.

If income checks and onboarding are where your team loses time, that narrow focus is the point.

If you need to parse invoices, contracts or receipts, look elsewhere.
