DigiParser vs Stalwart mail-parser

DigiParser uses AI and OCR to extract structured data from documents and emails. It processes PDFs and images, including JPG and PNG files, and lets users define custom parsers with chosen fields and formatting. Its payslip parser extracts earnings, deductions, year-to-date figures and employer information, and supports batch processing of hundreds or thousands of payslips. DigiParser provides web and API access, including a REST API, webhooks, Zapier and Make; its integration directory lists more than 5,000 connected apps and software. The payslip parser page claims 99.7% extraction accuracy, support for over 100 languages, and SOC 2 Type II and GDPR compliance. Intended users listed for that parser include lenders, HR teams, financial institutions, background check providers and accounting teams. Support includes documentation, video tutorials and email. The free plan covers 100 documents per month without requiring a credit card, and a free trial is available. Paid plans start at $14 a month for 100 payslips; enterprise pricing is offered for 1,000 or more documents per month.

Stalwart mail-parser is a free, open-source Rust library for parsing email messages. It supports Internet Message Format RFC 5322, MIME RFC 2045–2049 and other internet messaging RFCs, while attempting to handle messages that depart moderately from those standards. Parsed output includes a MIME tree, text and HTML body lists, and attachments. If one alternative is missing, the library can convert HTML to plain text or plain text to HTML. SIMD kernels accelerate scanning on supported targets, while transfer decoding and charset conversion wait until content is read. Returned strings generally reference the original input message. WHATWG encoding labels are recognized, and the optional full_encoding feature adds legacy multibyte sets including Shift_JIS, Big5 and GB18030. Defaults allow nesting depth 64, 10,000 MIME parts and three decoded nested-message levels. Rust 1.98 is required. No feature is enabled by default; serde adds serialization. The library is licensed under MIT or Apache-2.0 and costs nothing.
