Auto-Fill Legal PDF Forms from your source document
Upload your blank TR-205, I-864, Form 130, or any legal document alongside a source file like a completed form, client intake sheet, or case brief.

Upload your W-9, 1099-NEC, 1040-X, Form 941, or any tax PDF, and Simplicity AI instantly converts it into a clean, editable digital form. No more printing, scribbling, and scanning back. Just a structured form you can fill, auto-complete with AI, and export ready for filing.
Fill Out Immigration Forms in Real Time. See Every Field Update Instantly.
Upload your DS-11 passport application, I-864 Affidavit of Support, DS-82 renewal, or any immigration PDF.

One workflow from blank form to signed document, ready to submit to insurers, providers, or the VA.
HOW IT WORKS
Use Simplicity AI Form filler in 3 steps
Whether it's a W-9 for tax season, a DS-11 for your passport, or a stack of I-9s for new hires, the workflow is always the same. Upload, fill, export.
1
Upload your PDF
Drag and drop your tax form, legal document, immigration application, healthcare PDF, or employment paperwork into the box. The AI form filler scans the layout, detects all fields, checkboxes, and dropdowns, and prepares the form for completion. Works with both fillable and non-fillable PDFs.

FAQ
Got Questions?
We've Got Answers.
Is Simplicity AI free to use?
Yes. Simplicity AI has a free plan so you can upload forms, test the AI form filler, and see how it fits your workflow before committing. No credit card required to get started.
What types of forms can Simplicity AI fill?
Pretty much anything in PDF format. Tax forms like W-9s and 1099-NECs, immigration documents like DS-11s and I-864s, employment paperwork like I-9s and W-4s, healthcare forms, legal filings, construction permits, mortgage documents, and more. If it's a PDF, Simplicity AI can handle it.
What if my PDF isn't a fillable form?
That's one of the things Simplicity AI does best. Upload any flat, static, or scanned PDF and the AI automatically detects text fields, checkboxes, and dropdowns, then converts it into an interactive, fillable form. No manual setup needed.
How does the AI auto-fill feature work?
You have two options. You can answer questions through a simple guided interface, and the AI fills the PDF as you go. Alternatively, you can upload a source document, such as a previously completed form, and Simplicity AI reads both files, matches the fields, and auto-fills the fields. Either way, you review before exporting.
Is my data safe on Simplicity AI?
Yes. Your documents are protected with encryption and controlled access. We don't share your files, we don't use your data to train AI models, and you stay in full control of who sees your documents. Security isn't an add-on here. It's built into every step.
Can I review and edit forms before exporting?
Absolutely. Whether you filled the form manually or let AI complete it, you can review every field, make edits, and add your signature before downloading or sharing the final document. Nothing gets exported until you say it's ready.
Do I need to download anything to use Simplicity AI?
No. Simplicity AI works fully online through your browser. Upload, fill out, sign, and export without installing anything. We also have a mobile app if you prefer filling out forms on your phone or tablet.
How is Simplicity AI different from other online form fillers?
Most form tools simply provide a text box on top of a PDF. Simplicity AI actually understands the form. It reads field types, context, and intent, then fills them intelligently. It handles fillable and non-fillable PDFs, lets you auto-fill from source documents, converts static forms into interactive ones, and includes built-in e-signatures, all in one place. No switching tools, no workarounds.
