Types of AI PDF tools
Chat-first document assistants
AskYourPDF, Humata and ChatPDF start from a chat box over uploaded files. You get cited answers, multi-document questions and a free tier with page caps, but little in the way of editing or form filling. They suit research, contracts and study material.
Credit-based all-in-one apps
LightPDF and UPDF bundle conversion, OCR and editing with an AI layer that is metered by credits or question counts. One license covers desktop, mobile and web, so the AI is a feature of a PDF toolbox rather than the product.
Free consumer editors with AI
PDFgear and Smallpdf serve people who handle PDFs a few times a week. PDFgear is free to download and use. Smallpdf runs a browser toolbox where AI features are limited on the free tier and open up on paid plans.
Established editors that added an assistant
Foxit, Nitro and Adobe Acrobat sell full PDF editors for offices and add AI chat, summaries or redaction on top. They fit organizations that already standardize on one editor and want one license, one admin console and one vendor to audit.
