AI agent · Edit · Fill · Sign · Convert

The AI-native PDF editor.Just tell it what to do.

The agent is built in. Type “redact every SSN” or “merge these three and compress”, and it redacts, fills forms from your saved info, edits text and pages, translates and converts. Nothing changes until you apply it, and one undo takes it back.

Free account · no card, no end date

A services agreement is open in the editor with the AI assistant's prompt box at the bottom. The request “Change the fee to $4,200, fill the client PO number with PO-2210 and add page numbers at the bottom right” is typed in; the assistant shows its steps, then proposes three changes for review (fee text replaced, PO field filled, page numbers added). After Apply changes, the page shows $4,200, PO-2210 and a page number. Then the AI side panel opens, “When are invoices due?” is typed into its prompt box, and the answer “within 30 days” quotes the sentence and links to page 1.

Recorded in the current app with a sample agreement. Names and companies are fictional.

The AI agent

Just say it. The agent does the work.

Type the job the way you’d ask a colleague. The agent picks the tools, shows each step, and hands back changes for you to approve or a brand-new file.

    Your PDF stays as it was.

Illustrations with sample documents: counts, names and file sizes are examples, not results. Requests start at 1 AI credit and longer ones use more; translation, OCR and conversions also use their usual allowances.

Why AI-native

AI-native, not an add-on.

In PDFBetter the AI isn’t a side panel next to the editor. It’s how you work: tell it the job, check what it did, apply.

  1. One box for every job

    Type the request in the editor or on your dashboard, and soon in the Chrome extension. No menus to hunt through.

  2. You approve every change

    Edits come back as a list, page by page. Apply them as one step; one undo takes them all back.

  3. Originals stay untouched

    Merge, split, compress, convert and OCR create new files. The ones you started with don’t change.

  4. Fills forms from My info

    Save your details once, then say “fill this with my info”. ID numbers, bank and card numbers and passwords are never stored.

  5. Works across documents

    Pick several files from your library: merge them, or pull pages from one into another, in a single request.

  6. Answers cite the page

    Ask anything about a document: the answer names its page, and quotes from the text are checked word for word.

  7. On the Free plan too

    Every account gets AI credits, Free included (20 a month). A request starts at 1 credit, more for longer jobs; translation, OCR and conversions use their own allowances.

  8. Private AI mode

    Turn it on in Settings on any account: nothing derived from your documents is kept after a request, and chats aren’t saved.

When is the fee paid?

The $3,800 fee is invoiced in two parts: 50% on signing and 50% on delivery, payable within 30 days 1.

How Chat with PDF works

One editor, four modes

Everything you'd print it for — done on screen.

Line items are typed into an invoice template — a description, a quantity and a unit price — and the amount for each row calculates as the numbers are entered.

Fill any form, even a flat one

Type into fields, tick boxes and add dates. Totals in our templates calculate as you type.

  1. Edit & fill, Invite to sign and Create form are three modes of the same editor
  2. Amounts are formula fields: they calculate as you type
  3. The field navigator counts what's left and jumps to the next field
Fill a PDF

In Edit PDF mode a word in an existing paragraph of the agreement is selected and retyped; the paragraph keeps its original font and size.

Change the words already on the page

Click a paragraph of the original and retype it in the detected font.

  1. Existing text becomes editable paragraphs, not just lines
  2. The detected font and size are kept — here Times at 11.5 pt
  3. Switch between filling fields and editing the page itself
Edit a PDF

A flat client intake sheet is opened in Create form mode; Detect fields finds the blanks, boxes and signature line and adds them as form fields.

Turn any PDF into a fillable form

Place fields by hand, or detect the boxes and lines on a flat page.

  1. Pick a field type, then click the page — or drag it
  2. Detect fields finds the boxes and lines on a flat PDF
  3. Every field keeps a label, a name and its own rules
Make it fillable

In Invite to sign mode a signer is added by name and email, then a signature field and a date field are placed on the client's signature line in that signer's color.

Send it to be signed, in order

Add signers, give each one their fields, and send with reminders.

  1. Recipients sign in order, or all at once
  2. Fields take the color of the person who fills them
  3. Fields go to the selected recipient
Request signatures

E-signatures

Their own key, on their own device. Sealed when done.

Every signer signs with their own cryptographic key, created in their browser and never leaving their device. Every completed PDF is digitally sealed and independently time-stamped, with the evidence built into the file, so changing one byte shows. Send in order with reminders, and require an emailed code on any plan.

Forms & sharing

Publish a form. Share a link. See who opened it.

Turn a PDF into a form people fill from a link, export the responses, or share a read-only copy with an expiry and a password. Still need a fax? Send it to any US or Canadian number from the same place. The free plan includes 50 form responses a month.

  1. Every answer names its page.

    30-second test

    Open Chat with PDF on any document and ask a question. Click the page chip in the answer: the document jumps to that page. Hover the chip to read the exact quote, which was matched word for word against the page before you saw it.

    Pages that are only images, such as photos and scans without OCR, are cited by page, without a quote.

  2. Browser tools never upload your file.

    30-second test

    Open your browser's developer tools on the Network tab, then merge two PDFs. The merged file downloads, and no request carries your documents.

    Open Merge PDF
  3. A signed PDF carries its own evidence.

    30-second test

    Send a signature request to yourself and sign it. Open the completed PDF's signature panel in a PDF reader: the PAdES seal and its RFC 3161 time-stamp are listed there. The Free plan includes 3 requests a month.

    The seal certificate comes from PDFBetter's own certificate authority, which is not on Adobe's trust list yet, so Acrobat shows the signer identity as not verified; change detection still works. The time-stamp is added whenever the time-stamping authority is reachable.

  4. Every limit is on one page. Nothing is pre-ticked.

Questions people ask

Do I need an account to use PDFBetter?

No. You can open any tool and do the work without signing up. Browser tools such as merge, split and rotate download without an account. For edited documents, a free account is needed to download, share or send — your draft is kept while you sign up.

What does the free plan include?

3 edited-document downloads, 3 signature requests, 50 form responses, 20 AI credits and 20 OCR pages each month, with files up to 10 MB. Downloads have no watermark.

Is it safe to upload confidential documents?

Files are stored privately per account and are only reachable through short-lived signed links. Guest drafts are deleted 1 hour after they're created. Tools marked “In browser” never upload your file at all. The security page explains storage, deletion and access in detail.

Are signatures made with PDFBetter legally valid?

In the United States, the EU, the UK and many other places, electronic signatures are generally valid for most business documents, with exceptions such as wills. With PDFBetter, every signer signs with their own cryptographic key, and every completed PDF is digitally sealed and independently time-stamped, with consent, timestamps and a tamper-evident audit trail built into the file. Our legality pages summarize the law by country — they are not legal advice.

Can I edit the existing text in a PDF?

Yes. Click a line of text to replace it; PDFBetter covers the original and retypes your change in the closest matching font. Fonts embedded as subsets can't always be matched exactly, and the page tells you when that happens.
