You can drop in a PDF, Word document, PowerPoint deck, Markdown or text file, paste a link, or point it at a YouTube video, then ask questions in natural language. Answers are grounded in your sources and come with clickable citations so you can verify anything straight from the original page. Beyond one-off Q&A, the platform supports folders and multi-file chats, so you can query a whole reading list at once and compare findings across documents. A side-by-side layout keeps the conversation and the document open together, while translation lets you read material in another language or ask questions in a language different from the source. The team has expanded the suite with an AI writer, AI detector, flashcards, slide generation, and a dedicated research mode. Access is browser-based and device-agnostic, with desktop and mobile apps available. The free tier covers a limited number of documents per day with no sign-up required for the core experience, while the paid Plus plan removes limits and unlocks advanced features. Enterprise-grade handling (SSL in transit, encrypted storage, SOC 2 Type II storage provider) is advertised, and users can delete their documents at any time. **Pricing & Plans:** Freemium. A free tier lets you analyze a limited number of documents per day, and the core chat experience works without creating an account. ChatPDF Plus is a paid subscription that adds unlimited document analysis and advanced features — check the site for current plan details and regional pricing. - **Cited answers:** Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching. - **Multi-file chat and folders:** Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once. - **Summarization and translation:** Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language. - **Study and writing tools:** Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text. - **Side-by-side reading view:** Keep the chat panel and the PDF open together so answers stay linked to the original content while you read along. **Strengths:** Answers include clickable citations tied to the original page, which makes fact-checking straightforward; Works with PDFs, Word, PowerPoint, Markdown, text, YouTube links, and web pages in one place; No account needed to try the core chat experience, and the free tier covers light daily use; Multilingual: upload in one language and ask questions in another **Limitations:** The free plan caps how many documents you can analyze each day; Advanced features such as unlimited analysis and the full study toolkit sit behind the paid Plus subscription; Very large documents or heavy multi-file sessions can be slower and may hit size limits [Profile (Markdown)](https://openaitools.app/tool/chatpdf.md) ## PrivacyDoc PrivacyDoc is a document analysis portal built for people who have to read a lot of long-form material and would rather query it than skim it. Access is frictionless: there is no account creation or password to remember, you simply sign in with Google and start uploading. Supported formats cover PDFs, ebooks and structured text files such as TXT, CSV and JSON, which makes it usable for scientific papers, academic articles, books, user manuals and training documents within the same interface. The core interaction is question answering. You submit a query about your uploaded document and the system returns a natural-language response drawn from the content, backed by AI and advanced search rather than keyword matching alone. Alongside answers, the product advertises text summarisation and data extraction, so you can either get a condensed overview or pull specific facts out of a long file without reading it end to end. Privacy is the stated differentiator, and it shapes how the service is described. Uploaded files are not stored permanently and data is deleted once you log out of the site, which matters when the documents in question are confidential corporate material or unpublished research. The tool is offered at no cost, with a stated per-document query limit and a maximum file size, which makes it an accessible option for individuals who want quick document insight without a subscription. **Pricing & Plans:** Free. PrivacyDoc is advertised at $0/month with no account fees; the free tier covers querying one PDF or ebook per session up to a maximum file size of about 10MB. - **Chat with your documents:** Submit natural-language questions about an uploaded PDF or ebook and receive direct, content-grounded answers instead of search results. - **Multi-format upload:** Accepts PDFs, ebooks and structured text such as TXT, CSV and JSON, so papers, manuals and datasets can share one workspace. - **Summaries and data extraction:** Condense long documents into quick overviews or pull out the specific facts and figures you need. - **Passwordless Google sign-in:** No account creation or password management — log in with your Google account in a couple of clicks. - **Privacy-oriented handling:** Files are not retained on the service and your data is deleted when you log out. **Strengths:** Completely free with no account setup beyond Google sign-in; Handles PDFs, ebooks and structured formats like CSV and JSON in one place; Answers come from your own uploaded content rather than the open web; Stated policy of not storing files and deleting data on logout **Limitations:** Free tier is limited to one document up to roughly 10MB per query; Requires a Google account, which may not suit every workplace; Interface and feature descriptions are fairly minimal, with little detail on model choice or accuracy limits [Profile (Markdown)](https://openaitools.app/tool/privacydoc.md) ## Frequently Asked Questions ### How do ChatPDF and PrivacyDoc compare in monthly traffic?
