Eliminating repetitive paperwork with precision document intelligence.
SpaceFill was created to transform hours of tedious, error-prone data entry into instant, vector-accurate PDF submissions. Built for legal professionals, HR teams, tax filers, and individuals.
Standard PDF forms shouldn't take days of manual typing.
Official USCIS petitions, IRS tax documents, and employment contracts often feature hundreds of isolated input boxes, comb-style digit slots, and checkboxes.
Professionals spend countless hours manually re-typing information that already exists in resumes, corporate bios, and spreadsheets. One misplaced letter or formatted date can lead to rejected filings.
Deterministic Matching & Native Object Injection
SpaceFill parses native AcroForm dictionaries directly. When you attach a resume or notes, our engine matches candidate data entities to form fields in seconds.
Populate 300+ fields in sub-second speed.
No screenshot flattening or blurry fonts.
