Plenty of forms still arrive as a Word document instead of a PDF: a client intake sheet from a partner firm, a vendor questionnaire, a one-off template someone built years ago and never converted. If you don't have Word installed, or you're on a phone, tablet, or Chromebook, filling one out by hand means either buying a Word license or fighting with a free viewer that won't let you type into the fields. There's a faster path that doesn't require Word at all.
To fill a Word form online without Microsoft Word, upload the .doc or .docx file to an AI form filler — it finds every fillable field and lets you complete it in a browser. Filly AI fills Word and PDF forms alike from a saved profile, then exports a finished file or a no-login e-sign link. Free plan covers 10 fills a month.

| Free online Word viewer | No | Often read-only — can't type into the layout | No | Free |
| Filly AI | No | Yes — AI detects fields in plain-text and table layouts | Yes — saved profiles | Free up to 10/mo, then $19/mo |
Do I need Microsoft Word installed to fill out a .docx form?
No. Any browser-based form filler that accepts Word uploads reads the document's text and structure directly — you never open it in Word. Upload the file, and the tool identifies blank lines, bracketed placeholders, and table cells that are meant to be filled, then presents them as fields you can complete on screen.
How does an AI tool find the fields in a Word document?
Word forms rarely use the same interactive "form field" objects PDFs do — they're usually plain text with underscores, blank table cells, or bracketed prompts like [Client Name]. Filly's AI reads the document's layout and language to infer what's being asked for at each spot, the same way it handles a PDF with no fillable fields at all.

Can I reuse the same answers across multiple Word forms?
Yes. Save your (or a client's) name, address, and other recurring details once as a profile, and every subsequent Word or PDF form pulls from it automatically — useful if the same vendor questionnaire or intake form comes up again next month with a different client. Start from a ready-made file in the template library or upload your own.
What file do I get back after filling a Word form online?
A completed copy in the original format, ready to download, plus the option to send a no-login link so the recipient can review and sign it in their browser — no requirement that they have Word or an account either.
Is this different from just typing directly into Word's own form fields?
If a .docx already has Word's built-in content-control fields (checkboxes, dropdowns, text boxes), you can fill those manually in Word or in a compatible viewer. The AI approach helps most when the document has no real form fields — just a static layout someone expects you to type over — or when you want the same details to populate automatically instead of retyping them every time, such as a service agreement reused across clients.
Frequently asked questions
Is filling a Word form online free?
Yes, up to Filly's free plan limit of 10 filled documents a month, no credit card required. Paid plans from $19/month raise the limit and add batch fill and e-signature.
Does it work with scanned or image-based Word documents?
If a "Word form" is actually a scanned image pasted into a document, treat it like a scanned PDF — Filly's OCR reads the text in the image and detects fields from there.
Can I edit the filled Word document afterward?
Yes. The completed file downloads as an editable document, so you or the recipient can make further changes before it's finalized.
Does the AI store the Word document I upload?
Uploaded documents and profile data are encrypted and not used to train AI models. See the security page for details on data handling and deletion.
