Which AI PDF editor actually helps you get work done?

Foxit is the only major editor here that puts AI in the base subscription instead of selling it separately. Its AI Assistant comes with PDF Editor and Editor+, and every Foxit account, including the free Reader, gets 300 AI credits a month. You can ask the document questions, summarize it, translate it, generate bookmarks, or turn it into a "Smart Podcast" you listen to.

Credits need a bit of attention. Foxit doesn't publish a per-action rate: credit use is tied to the actual cost of each task, so a long document burns more than a short question. Credits reset every month and don't roll over. If you run out, the paid pack costs $49.99 a year ($4.99 a month) for 2,000 credits a month. The tip other roundups skip: on a compatible computer, Foxit's local AI runs on your machine and uses no credits at all, which also solves the "my file went to the cloud" problem.

The catch is the lifetime license. Foxit PDF Editor 14, a one-time $209.99, doesn't include the AI Assistant, cloud features or Smart Redact. If you want the AI, take the subscription.

Here's what most roundups still get wrong: Adobe no longer includes the AI Assistant in Acrobat Pro, and the add-on is now sold only to students ($1.99 a month). Adobe's pricing page lists AI tools as "not a feature" on Pro and puts them all in Acrobat Studio: $24.99 a month on an annual plan, $299.88 prepaid, or $34.99 month to month. Pro is $19.99. Any article quoting "Pro plus $4.99 a month for AI" is out of date.

What Studio gets you: an assistant to chat with your documents, summaries, PDF Spaces that group up to 10 PDFs, and presentation building. On contracts, Acrobat's AI gets the facts right and flags missing clauses; its real edge is the citation next to each bullet point, which takes you straight to the source passage. Adobe's help pages also describe editing text from a prompt (replace, rewrite, redact) for paying users with the app set to English: try it during the trial before you count on it. Adobe states it doesn't use your data or interactions to train its models.

One billing warning from the field: users report a 7-day AI Assistant trial that converted into a paid plan on its own, and AI charges that continued after they canceled Pro.

UPDF's AI does the most: it summarizes, translates, rewrites, explains a passage and searches the document by meaning rather than exact words. On Windows and macOS, agents open the right tool for you from a prompt. UPDF also advertises AI form filling; we've only seen that described on its own site. One nuance: "rewrite" gives you new text, it doesn't edit the file for you.

Read the price in two lines. A UPDF Pro license, yearly or lifetime, covers 4 devices; the US pricing page doesn't show its amount, so check it at checkout. The AI is a separate subscription that renews at $69 a year, and the lifetime license only covers Pro. The trial gives you 5 PDFs, 100 questions, 100 pages and 100 MB per PDF. With the AI plan, UPDF advertises unlimited document AI plus 1,000 AI credits a month, and credits don't roll over.

Reviews love the AI but complain about billing: Pro buyers say they were charged for AI they never ordered, or rebilled a year later. Features also vary by platform.

PDFgear is the outlier: its AI copilot is free, with no account, no paid plan listed and no published limit. It runs on a ChatGPT integration to summarize, translate, rewrite and answer questions about your document. You need an internet connection for the chat, since answers come from the cloud.

Two limits. PDFgear publishes no quota, but its chat gives no clickable link back to the page the way Acrobat does: on a long document, check every answer yourself. And it's free "during this phase": the company has mentioned paid AI services down the road. On forums, the recurring worry is data, since documents go through ChatGPT; PDFgear says the copilot can be turned off.

Readdle's PDF Expert includes its PDF Copilot assistant in both the subscription and the lifetime license: there's no add-on to buy. Copilot answers questions about the document, summarizes it and pulls out key points. It needs macOS 13 or iOS 16 or later.

The quota is the real limit. On Mac, the trial gives you 50 requests and a subscription 200. The subscription costs $79.99 a year across iPhone, iPad and Mac; the $139.99 lifetime license is Mac only, and Readdle warns that new features may cost extra. If you fire off dozens of questions a day, you'll feel that cap.

iLovePDF isn't a desktop editor, but its AI does one thing few tools do well: translate a PDF while keeping its layout. Built-in OCR means it can translate scanned documents too. Without a paid account you get one free translation a day, on files up to 15 MB.

Premium is $60 a year ($5 a month) or $9 month to month. It includes summaries and translation with "standard AI" and raises the file limit to 200 MB. Advanced AI runs on credits (2,000 AI credits), capped at 67 pages per task. The free tier has no AI credits at all.

Wondershare sells PDFelement's AI as a separate add-on, PDFelement AI, listed at €3.99 a month on its European stores. It chats with the document, summarizes, rewrites, explains, proofreads and flags AI-written content. The trial gives you 10 uses.

The software itself is $79.99 a year on Windows (auto-renewing plan on the US store), with a perpetual license from $51.99. As with UPDF and Foxit, the perpetual license doesn't include the AI. Wondershare's own pages give two different figures for how many uses the add-on includes, so ask before you pay if you plan heavy use.
