Feature-by-feature
AI PDF Summarizer is laser-focused on PDF documents: it summarizes PDFs up to 100 MB, lets you ask follow-up questions via chat, and supports 90+ languages for summaries. It also bundles PDF editing, signing, conversion, and form filling. Kagi is a broader ecosystem: its core is an ad-free, private search engine with advanced search controls (bangs, site limits), and it includes an AI Assistant with multiple LLMs (GPT-5.5, Claude 4.8 Opus, Gemini 2.5 Pro) that can answer questions grounded by search. Kagi Summarize summarizes articles/videos, but not uploaded PDFs. Kagi also offers Orion browser, Translate (240+ languages), News briefs, and Small Web curation. Neither tool has OCR for scanned PDFs, but Kagi disables AI features on request. AI PDF Summarizer requires no software installation; Kagi's Orion browser is a desktop browser. Both are browser-based, but Kagi also has a mobile Translate app.
Pricing compared
AI PDF Summarizer operates on a freemium model: you get one free summary and three chat questions, then premium plans start at $4.99/month for unlimited summaries and chats. No mention of annual discounts. Kagi is also freemium but subscription-based for full search access; exact pricing tiers are not specified in the provided data. However, Kagi recently disabled free Translate access (now subscription-only). Kagi is user-funded (no ads), so all features likely require a paid plan after a free trial. For a dedicated PDF summarizer, the $4.99/month entry is transparent. Kagi's cost is less clear but likely higher for the full suite. Neither offers bulk or team-specific pricing details in this data.
