Instafill.ai is an online AI form filler that reads any PDF or Word document, detects every field, and automatically completes it using data you already have. Upload a form, let the AI extract and map answers, review the result in a visual editor, then export a finished document in under a minute.
QuickFiling provides specialised AI assistants that prepare complete, ready-to-file packages for US immigration and academic admissions. You pick a specialist — Dr. NIW for EB-2 National Interest Waiver, Dr. EB1A for extraordinary ability, Dr. EB1B for outstanding professors and researchers, Dr. I-485 for adjustment of status, or Dr. EB-5 for investor petitions — and it guides you through the criteria, helps organise your evidence, drafts petition letters and exhibits, auto-fills USCIS forms, and assembles everything into one typeset PDF you can review and download.

Instafill.ai is an online AI form filler that reads any PDF or Word document, detects every field, and automatically completes it using data you already have. Upload a form, let the AI extract and map answers, review the result in a visual editor, then export a finished document in under a minute.
Automatically detects and maps every field in a flat PDF or Word form, using semantic understanding rather than rigid templates.
Each filled field can display its source and the reasoning behind the value, making verification fast and auditable.
Runs concurrent parallel field filling and handles structured row data, so multi-form packets and repeating tables are completed together.
An MCP server lets you fill PDFs from inside Claude Desktop, Code, or ChatGPT, plus n8n and Zapier automations for wider workflows.

Dr. NIW, Dr. EB1A, Dr. EB1B, Dr. I-485, and Dr. EB-5 each guide you through the specific statutory criteria and requirements for that petition category.
Import documents by URL or email, run citation analysis, and let the assistant tell you exactly what supporting material is still missing.
Draft petition letters, sections, essays, and exhibits with section-by-section assistance — petitions, RFE responses, and admissions documents included.
AI fills the USCIS forms and an in-browser editor lets you highlight, cut pages, and annotate evidence PDFs, with full version history to revert any change.
