📜 Table of Contents
Every month there is a new best PDF AI list, and most of them are the same five SaaS products. This one is different: we split the category into three jobs and compared the tools that actually excel at each, including self-hosted options with verified GitHub data.
Three Jobs, Three Winners
Parsing (for developers): MinerU (76,942 stars), Docling (64,320 stars) and Marker (38,453 stars) beat any commercial API on price (free) and control; the trade-off is maintaining infrastructure. Chat with documents: AnythingLLM (64,418 stars) wins for individuals, RAGFlow (86,955 stars) for teams that need verifiable answers, Kotaemon (25,690 stars) for small-group deployments.
Summarization (commercial): for one-off summaries of long documents, ChatGPT upload, Claude attachments, and Gemini are hard to beat on convenience - no setup, excellent long-context handling. The cost is per-token and documents leave your machine; the self-hosted alternatives cover the same need privately.
