Indian language documents
Plan for mixed scripts. Review for accuracy.
Invoices and forms in India may combine Hindi, Bengali, Tamil, Telugu and other regional scripts with English. Preserve the source script and check names, identifiers, amounts and table columns against the original document.

Why Traditional OCR Fails Your Business
Flat text can lose table structure and reading order. In documents that mix English with Indian scripts, reviewers should also verify script, names, numbers and the columns those values belong to.
Structure, not just characters
Every column, table, and hierarchy remains a distinct spatial layer.
See the Indian invoice accuracy checklist for field and table checks.
Traditional Flat OCR
Legacy Tech- ✕Flattens tables into disorganized, tab-separated character streams.
- ✕Multi-column reading order gets merged horizontally into jumbled text.
- ✕Outputs raw .txt files that require hours of formatting into Word or Excel.
- ✕Forces documents into public cloud pipelines with uncertain retention.
- Borderless Table Reconstruction: Automatically builds native cells with intact totals and line items.
- Hierarchical Layout Geometry: Preserves headings, sidebars, margins, and paragraph structures.
- Native Microsoft Word (DOCX): Generates fully editable, formatted DOCX files ready for distribution.
- Local Folder Watcher & Zero-Retention: Strict in-memory RAM processing or 100% on-device local execution.
