Rearrange a PDF by describing what you want
Quick answer
Describe the change in plain language — "keep only the signed pages", "drop everything after the exhibits" — and Filly's AI decides which pages that refers to. It works out the page list and applies it in one pass; the reordering itself is done by ordinary code, not guessed. Your original file is left untouched, so if the result is not what you meant, rephrase and run it again.
When you’d use this
A long scan you haven't read yet
Working out which of sixty scanned pages are the signed ones means opening and checking each. Describing what you want is faster than building the page list by hand.
A rule that's easier said than counted
"Everything except the blanks" is one sentence and a tedious page-by-page inspection. This turns the sentence into the list.
How to do it
- 1Open the PDF tools and choose AI organise.
- 2Select the PDF and describe the change you want in plain language.
- 3It works out which pages you meant and applies the change in one pass — there is no preview step.
- 4Download the result and check it. The note tells you how many pages it kept.
What it doesn’t do
The AI chooses which pages, but it does not invent page numbers or rewrite content — a deterministic function performs the actual reordering. It can still misread an ambiguous instruction, and there is no preview, so check the downloaded result. Your original file is unchanged: rephrase and run it again, or use the manual page-selection tool if you would rather build the list yourself.
Frequently asked questions
How does AI page organising work?
You describe the change in plain language. The AI reads the document and decides which pages to keep, drop or reorder, then a deterministic function carries that out and returns the new file. The AI decides what to do — it never performs the edit itself, and it never rewrites your content. It runs in one pass, so check the result rather than a preview.
Can it get the pages wrong?
It can misread an ambiguous instruction, and it applies its choice without showing you a plan first — so check the downloaded file. Your original upload is never modified, so the fix is to rephrase and run it again, or to use the manual page-selection tool and build the page list yourself.
Is my document used to train AI models?
No. Uploaded documents are not used to train AI models. Analysis runs through Anthropic's Claude API and the details are on the security page.
The tools are the side of it
Filly is a form filler first: save a client’s details once and every form you upload afterwards fills itself from that profile. These PDF tools exist because the paperwork around a filing needs assembling before and after it’s filled.
