The AI-powered Adobe Acrobat alternative
Adobe Acrobat is the PDF standard and the most complete toolset for the format — edit, convert, OCR, redact, rearrange, Prepare Form field detection, Fill & Sign, and Acrobat Sign — across desktop, web and mobile.
Quick answer
Filly AI is an Adobe Acrobat alternative for people whose job is filling forms, not editing PDFs. Acrobat's Fill & Sign detects where the fields are and leaves you to type every value; Filly reads the fields too, then fills them from a client profile saved once, so the next form opens already complete — plus batch fill across clients and no-login e-signature.
Where Adobe Acrobat is strong
Acrobat invented the format and still does more with it than anything else. For redaction, conversion, rebuilding page order, accessibility tagging, or working offline, nothing here competes — and every recipient already has Reader, which matters more than it sounds.

Why teams switch to Filly
Acrobat finds the fields; it doesn't know the person
Prepare Form detects where the boxes are, which is the easy half. Filly detects them and then fills them from a client record you saved once, so the tenth form for the same person costs nothing to complete.
Auto-Complete is a typing history, not a client record
Acrobat's Auto-Complete suggests values you have typed before on that machine, one field at a time. It is not a profile you can reuse deliberately, share across devices, or fill a whole form from in one action.
Batch across clients
Produce the same form for many people in one run, delivered as a single ZIP — up to 5 clients per run on Solo and 20 on Pro. Acrobat is built around the document in front of you, one at a time.
You are licensing an editor to do data entry
If the actual task is retyping the same details into form after form, a full PDF suite is a lot of software for the job. Filly is free to start with no card, then $19/month.

Get startedFrequently asked questions
- Does Adobe have an AI form filler?
- Not in the sense most people mean. Acrobat has three AI-adjacent features — AI Assistant (summarises and answers questions about a document), Auto-Complete (suggests values you previously typed on that machine), and Prepare Form (detects where fields are) — and none of them fills a form from your saved client records. That is the specific gap Filly AI fills.
- What is the best Adobe Acrobat alternative for filling forms?
- Filly AI, if filling is the job rather than editing. It reads any PDF or DOCX including scans via OCR, fills from reusable client profiles, batch-fills across clients (up to 5 clients per run on Solo and 20 on Pro) and sends no-login e-sign links. There is a free plan and no card is required. If you need redaction, conversion or offline editing, stay on Acrobat — those are not things Filly does.
- Can Filly AI replace Adobe Acrobat?
- Only for form filling. Filly does not edit PDFs, convert formats, redact, rearrange pages or work offline. Plenty of people keep Acrobat for document work and use Filly for the repetitive filling — they solve different problems and the overlap is small.
- Is Adobe Fill & Sign discontinued?
- The standalone Fill & Sign mobile app was retired and folded into Acrobat Reader Mobile in 2025, per Adobe's own migration notice. The Fill & Sign tool inside Acrobat on desktop and web is unaffected — it was merged, not shut down.
- Is Filly AI cheaper than Adobe Acrobat?
- They are priced for different products, so compare against your actual use. Acrobat is a subscription to a complete PDF suite; Filly is free to start and $19/month for the filling workflow. If you also need editing and conversion, you are buying different things and price is not the deciding factor.
