In their own words
ChatPDF
ChatPDF lets users summarize documents and ask questions about their contents using conversational AI. Answers include citations that point to references in a PDF, and users can organize files in folders or discuss multiple PDFs in one conversation. It accepts PDFs in any language and supports conversations in any language; listed file types also include Word, PowerPoint, Markdown and text. Sharing links can be created, with access permissions managed or revoked. ChatPDF says documents are encrypted during transfer and storage and can be deleted by the user. Queries are routed dynamically between GPT-4o and GPT-4o-mini. The service works in a browser on any device and is listed for Android, iOS, Linux, macOS and Windows. Its backend API accepts uploaded PDFs or public URLs and lets users query them to build custom PDF chatbots. The API documentation limits each PDF to 2,000 pages or 32 MB and describes the chat API as stateless. The Free plan costs nothing and allows two documents per day.
TLDR This
TLDR This summarizes articles and other text, with inputs ranging from a webpage address or pasted text to PDF, DOC and DOCX files up to 25 MB.

Other tools paraphrase text in different voices and styles, filter weak arguments and speculation, and surface relevant points. A reading view removes ads, popups, graphics and other online distractions. The service also provides API access through a link to RapidAPI. TLDR This has a free plan and paid plans, including Starter at $4 a month. The Free plan includes unlimited basic summaries, 10 advanced AI summaries and up to 10 paraphrases as one-time allowances. The service says uploaded files are not opened unless requested and personal information is not sold to third parties. Data is encrypted in transit and at rest; deleted data is purged within 30 days.
