## How each alternative compares with Adobe Acrobat

- **Foxit PDF Editor** (Paid, $129.99/user/yr, checked 2026-11-14): Foxit lists a $209.99 one-time perpetual PDF Editor 14 next to $129.99 a year subscriptions, and its AI Assistant comes with 300 credits a month; Adobe's page lists subscriptions only. Switch if you edit PDFs daily, want a cheaper per-user licence or a one-time perpetual option, and AI is secondary. Stay with Adobe Acrobat if you need Adobe's PDF Spaces, Adobe Express tools and AI Assistant bundled in one Studio subscription.
- **Smallpdf** (Free plan + paid, $15/mo, checked 2026-11-14): Smallpdf runs in the browser with 30+ tools; its AI tools cap files at 50 MB, and documents at 25-35k words on Free or 100k on Pro. Switch if you convert, compress and sign PDFs occasionally in a browser and do not want desktop software. Stay with Adobe Acrobat if you edit complex layouts or fill long forms offline in a desktop application.
- **PDF.ai** (Free plan + paid, $10/mo billed yearly, checked 2026-11-14): PDF.ai Pro allows 100 PDF uploads and 1,000 questions a month, with OCR up to 10 pages per file; its free-tools list names split, merge and compress but no text editor. Switch if you only need to ask questions of reports and papers and want to pay about half of Acrobat Pro. Stay with Adobe Acrobat if you must edit text, redact, convert or sign PDFs inside the same application.
- **AskYourPDF** (Free plan + paid, $11.99/mo billed yearly, checked 2026-11-14): AskYourPDF's free plan allows 50 questions and 1 document a day (100 pages, 15 MB); Premium raises that to 1,200 questions and 2,500 pages per document. Switch if you want a free daily allowance for PDF questions and a Chrome extension before paying anything. Stay with Adobe Acrobat if you edit and sign PDFs more than you question them, or need a desktop editor.
- **Humata** (Free plan + paid, $9.99/mo, checked 2026-11-14): Humata meters usage in pages: Free gives 60 pages a month, Expert 500 pages with extra pages at $0.02 each, and Team 5,000 pages for up to 10 users. Switch if you analyse a few long documents a month and prefer paying per page rather than a flat subscription. Stay with Adobe Acrobat if you want unlimited editing, signing and conversion tools alongside AI answers.
- **ChatPDF** (Free, Free plan; paid price not published): ChatPDF's FAQ states the free plan allows 2 documents every day; its homepage links a Plus upgrade but shows no price, and its /pricing URL returned a 404 page. Switch if you just need to ask one or two PDFs a day a question without creating a workspace. Stay with Adobe Acrobat if you want an editor that can change text, redact, combine and sign files.
- **NotebookLM** (Paid, Not checked): NotebookLM's address now redirects to notebook.google, titled Gemini Notebook, and is built to analyse uploaded sources; it does not edit, redact or sign PDF files as Acrobat does. Switch if you want to question several documents together and already live in a Google account. Stay with Adobe Acrobat if you need to edit, convert and e-sign PDFs rather than only analyse them.
- **Stirling-PDF** (Open source, $99/mo (hosted), checked 2026-11-14): Stirling-PDF's pricing page lists 60+ PDF tools in web, desktop and self-hosted form, with a $99 a month Team plan for 100 users instead of per-seat pricing. Switch if you want PDF edit, redact and OCR tools on your own server so documents never leave your network. Stay with Adobe Acrobat if you want Adobe's AI Assistant answering questions inside PDFs without running anything yourself.
