## ChatPDF

ChatPDF started as a simple "chat with your PDF" utility and has grown into a full research and study workspace. 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

## Elephas

Elephas is built for the kind of work that should never be pasted into a general chatbot: contracts, client files, policies, research notes and reports. Instead of uploading documents to a cloud service, you point Elephas at files or entire folders on your machine. It reads and indexes them locally, then lets you ask questions in everyday language. Every answer comes with a source reference, so you can open the quoted passage and check it against the original page, slide or sheet.

The privacy model is the core of the product. Documents, the search index and your chats stay on your computer in an encrypted database. When you ask a question, personal details such as names, emails and phone numbers are masked before the request leaves the device, and you can inspect exactly what was hidden under each answer. You also choose where answers are generated - the default Elephas gateway, your own API key for OpenAI, Claude or Gemini, or a local model that runs entirely on your machine with nothing sent anywhere.

Elephas supports documents in English, German, Spanish, French, Japanese and Chinese, with cross-language search, and ships as a macOS and Windows desktop app. A team tier lets an organisation put shared contracts and policies into a common Brain with role-based access, private per-person chats and end-to-end encrypted sync. Pricing is a 7-day free trial with no card required, followed by individual plans and a Teams option at $29 per person per month with no minimum team size.

**Pricing & Plans:** Free 7-day trial with no credit card required. After the trial, individual subscription plans apply, and Elephas Teams is priced at $29 per person per month with no minimum team size.

- **Local document indexing:** Files, folders, PDFs, Word documents, spreadsheets, slides and scans are read and indexed on your own computer rather than uploaded to a third-party service.
- **Answers with sources:** Every response cites the underlying file plus the page, slide or sheet it came from, so you can open and verify the passage yourself.
- **Personal detail masking:** Names, email addresses and phone numbers are hidden before a question leaves your device, and you can view exactly what was masked under each answer.
- **Choice of AI engine:** Use the default Elephas gateway, plug in your own OpenAI, Claude or Gemini API key, or download a local model so answers are generated on your computer with nothing sent.
- **Shared team Brains:** Invite teammates to a common Brain with manager, contributor or reader roles, keep individual chats private, and sync through end-to-end encryption.

**Strengths:** Documents, index and chats stay on your own machine in an encrypted local database; Every answer cites the exact file and page, making verification fast; You choose the AI backend, including fully local generation with nothing sent; Cross-language search across six languages without a language setting

**Limitations:** Desktop-only: there is no browser version, so you need macOS or Windows; Answers still travel to a cloud model unless you pick local generation, and cloud requests are not end-to-end encrypted; Automatic masking of personal details can miss things, so answers should still be reviewed
