Its all-in-one Pro plan suits those who want editing and AI bundled together. Users with only occasional, simple PDF needs may get by with free tools, and AI answers about documents should be verified, but for handling PDFs with editing plus AI in one place, LightPDF is a convenient, good-value choice.
