}Longlichi reads documents the way humans do — understanding headers, columns, nested tables, and footnotes as a single coherent structure.
Charts, stamps, handwritten notes, embedded images — Tohtoh extracts meaning from every element on the page, not just the words.
Define the exact JSON shape you need. Map fields, set validation rules, and get clean, predictable output every time.
Process a single receipt or a million-page backlog. Async queues and parallel workers keep throughput high without sacrificing accuracy.
Arabic invoices, Japanese contracts, German tax forms — Longlichi handles multilingual documents natively, no translation step required.
SOC 2 and HIPAA compliant with on-premise deployment options. Your documents never leave your infrastructure.
Extract line items, totals, vendor details, and payment terms from any format.
Identify key clauses, parties, dates, obligations, and renewal terms.
Extract identity details from passports, licenses, and verification forms.
Extract patient info, diagnoses, prescriptions, and lab results from clinical documents.
Process transaction histories, account summaries, and financial records for analysis.
Recognize and digitize handwritten notes, forms, and annotations with high accuracy.
