GDPR Compliant

PDFs were designed for printing,
not for data entry.

Existing tools treat PDFs as flat images. You're still stuck doing the heavy lifting, field by field, document by document.

Fragmented Layouts

Every government agency and insurance provider uses a different layout. Static templates break the moment a line moves.

Structural Blindness

Standard fillers don't see checkbox grids, tables, or dotted lines. They leave you to "draw" boxes manually every single time.

Zero Error Recovery

One typo in a flat PDF usually means starting over. No undo, no re-flow, no way to update data across multiple pages.

The JustFill Way

AI that actually
understands documents.

JustFill doesn't just overlay text. It maps your data to the logical structure of the form, handling complex elements like tables and nested checkboxes automatically.

Visual Field Mapping

Table & Grid Detection

Multi-page Consistency

Reusable Layout Logic

Mapping

99.4% Match

Detect every field.
Fill with precision.

Not just text boxes. We detect labels, table cells, checkbox groups, dotted fill lines, and tick marks — then let you verify every field before filling.

AI-Powered Field Detection

Our AI analyzes the full structure of your form — not just text boxes. It detects field labels, table cells, checkbox groups, dotted fill lines, and tick marks. Then it maps your data to each field based on context.

Secure & Private

Your documents are processed securely with encrypted connections. GDPR compliant with full data export and deletion rights.

Handles Complex Forms

Multi-page tax returns with nested tables. Insurance applications with checkbox grids. Government forms with dotted fill lines and tick marks.

Detect Once, Fill Forever

Save detected field positions as a template. Next time you upload the same form layout, it's recognized automatically — AI maps your new data to saved positions in seconds. Set up once, re-use for every new document.

Full Control Editor

Draw new fields, drag to reposition, resize with snap alignment. Multi-select, undo/redo, zoom and pan. Your adjustments are saved with the template.

Multi-Page Processing

Upload a multi-page form. Each page analyzed independently. Section headers detected, so fields from page 1 don't confuse fields on page 3.

From blank PDF to filled document
in four simple steps.

1

Upload Your PDF

Upload any PDF form — government documents, insurance claims, tax returns, customs declarations. Multi-page forms processed section by section.

2

AI Detects Every Field

Our AI analyzes the full document structure: field labels, input areas, table cells, checkbox groups, dotted fill lines.

3

Review & Fine-Tune

Every detected field appears on an interactive canvas. Drag to reposition, draw new fields, resize with snap-to-grid precision. Full control before filling.

4

Fill & Download

Paste or dictate your data by voice — names, addresses, IDs, dates. AI maps each piece to the right field. Review and adjust on the interactive canvas, then download the filled PDF.

PDF mail merge from Excel or CSV

Fill one existing PDF for every spreadsheet row.

Keep the original PDF layout. Import XLSX or CSV, match columns to reviewed fields, preview every record, and download the approved PDFs together as a ZIP.
