Both have AI. One charges extra for it. The other includes it.
PDFelement (by Wondershare) is a budget-friendly desktop editor with good editing tools, strong OCR, and AI features — but the AI costs an extra $3.99/mo on top of your license. Plans start at $79.99/yr or $129.99 perpetual.
ModernPDF is browser-based at $49/yr with AI document analysis, translation, and redaction included — no add-on, no credits. It's less capable as a desktop editor but includes AI intelligence that PDFelement charges extra for.

PDFelement has AI features — summarize, translate, grammar check, rewrite, explain. They work. But they cost extra: $3.99/month on top of whatever license you already bought. That means the real cost of PDFelement with AI is $79.99 + $47.88 = about $128/year. And even then, the AI is generic — it works the same on every document regardless of type.
ModernPDF includes AI at $49/yr. No add-on, no credit system, no surprise charges. And the AI is structured — it analyzes specific document types (non-competes, leases, NDAs, employment contracts) and produces reports with key terms, obligations, red flags, and exceptions tailored to that document type.
This is the core difference: PDFelement treats AI as an upsell. ModernPDF treats it as a core feature.
PDFelement is a genuinely good desktop PDF editor at a reasonable price. You can edit existing text with Word-like formatting controls, manipulate images, create forms, batch-convert documents, and run OCR that reviewers consistently praise. The interface is clean and modern — it looks and feels like a contemporary app, not legacy software.
ModernPDF's editing is basic: add text, images, shapes, highlights, signatures. You can't edit existing text in-place or create interactive forms. For hands-on document editing, PDFelement is the better tool.
PDFelement's desktop app processes files locally. But its AI features and cloud sync send data to Wondershare's servers. There have been user reports about upgrade prompts and account management friction.
ModernPDF processes all PDF operations locally in the browser via WebAssembly. For AI features, only extracted text is sent to Anthropic's commercial API via AES-256 bank-grade encryption — never the file itself. No text is stored after processing. No account required for free tier usage.
Yes. PDFelement includes limited AI credits with paid plans, but unlimited AI access requires a $3.99/month add-on. ModernPDF includes all AI features in its $49/yr Pro plan.
Yes. PDFelement offers similar editing capabilities at roughly one-third the price. It's consistently rated as one of the best budget PDF editors. ModernPDF is a different category — browser-based toolkit with AI, not a desktop editor.
Different strengths. PDFelement's AI handles generic tasks (summarize, rewrite, grammar check). ModernPDF's AI provides structured document analysis for specific document types with red-flag detection — a more specialized approach.
Yes. PDFelement's desktop app works offline for PDF editing (AI features need internet). ModernPDF also works offline for PDF operations after initial page load.
