What Does SpaceFill Actually Do?
Unlike consumer PDF tools that overlay blurry screenshot text, SpaceFill was purpose-built for the brutal precision demanded by federal agencies.
1. Native AcroForm Tree Injection
Reads the internal PDF object hierarchy to parse text boxes, comb-digit intervals, and radio buttons. It injects values directly into the PDF stream—ensuring vector sharpness and maintaining agency barcodes.
2. Deterministic Entity Extraction
Connects to candidate resumes, Word documents, or CSV spreadsheets. Accurately maps names, dates of birth, employers, job titles, and SOC wage codes without generative hallucinations.
3. Zero Cloud Perimeter Processing
Executes entirely on-device within your browser memory. No sensitive social security numbers, tax filings, or payroll records are ever sent to remote cloud databases or used to train AI models.
