Template editors hold you back
WYSIWYG editors force a proprietary template format. The result never matches the original stationery from InDesign or Word.

Why document generation is so frustrating
PDF libraries are low-level
iText, PDFBox, Puppeteer — hundreds of lines of code for a simple letter. Stationery overlays, page breaks, footers: all manual.
LibreOffice servers are unstable
Headless LibreOffice works in testing but crashes under load. Monitoring, restarts, memory limits: a DevOps project of its own.
Three steps to a finished document
1
Upload stationery
Export your approved company stationery as PDF. Separate PDFs for page one and following pages — just like real letterhead.
2
Place content
Define content areas with positions in millimetres. Fill them with HTML, Markdown, images, QR codes or barcodes.
3
Generate PDF
One API call with JSON, one finished PDF. On your stationery, millimetre-precise, identical every time.
What you can do with it
Stationery overlay
Separate PDFs for page one and following pages as background — like a real printer with a letterhead cassette.
Content areas
Place text, HTML, Markdown, images, QR codes and barcodes at exact millimetre positions on your stationery.
Markdown with styles
Markdown with tables, colour tags, page breaks and native paragraph styles from your ODT template.
