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) ## Elium Elium started as a collaborative, social knowledge-sharing product for companies and has since repositioned around a harder problem: keeping knowledge trustworthy once AI starts reading it. The platform organizes procedures, SOPs, checklists, policies, FAQs, decision trees, runbooks and research notes into spaces with owners, expiry dates and approval steps. Rather than acting as a searchable archive of everything, Elium is designed as a governed layer where every document has a responsible person, a validity date and a review path, so stale or missing content is flagged and routed back to somebody who can fix it. Because that governance layer is explicit, Elium can serve the same verified content to human teams and to AI assistants through RAG pipelines, Model Context Protocol connections, Microsoft Copilot, browser extensions and a full API. Permissions are enforced consistently, so AI agents only see what they are meant to see, and usage is observable: teams can track which answers were served, which were missed and which knowledge is at risk. Multilingual content and automatic translation support distributed, multi-site organizations. Elium is used by 1,200+ teams and references customers such as L'Oréal, BNP Paribas and the Council of Europe. It is ISO 27001 certified, GDPR-compliant and hosted in Europe, with options for private VPC, sovereign or on-premises deployment. Pricing is per active user, with a 10-user minimum and no usage credits on AI answers. **Pricing & Plans:** Per-user subscription billed monthly or yearly, with a free trial arranged through the team. Team is €15 per user per month and Corporate is €20 per user per month (annual billing, 17% saving); Enterprise pricing is custom. A 10-user minimum applies, and self-service portal visitors do not count as users. - **Governed source of truth:** Every document has an owner, an expiry date and an approval path, so knowledge stays verified and current rather than drifting quietly out of date. - **Knowledge lifecycle workflows:** Validity and expiration reminders, feedback management, review and multi-step approval workflows, plus gap and duplicate detection to surface what is missing or redundant. - **AI-ready delivery:** Serve the same governed content to ChatGPT, Claude, custom agents and copilots through MCP, RAG, REST APIs and a browser extension, with citations and one permission model. - **Multilingual and multi-site support:** Multilingual editor, decision trees and automatic translation help distributed operations, service and IT teams answer in their own language. - **European security and sovereignty:** ISO 27001 certification, GDPR compliance, EU-only data hosting and options for private cloud, sovereign or on-premises deployment, with SSO, SCIM and audit trail on higher plans. - **50+ connectors and integrations:** Connect Microsoft 365, SharePoint, Teams, Zendesk and Salesforce-style systems, import from Google Drive or OneDrive, and deliver answers where work already happens. **Strengths:** Explicit governance model — ownership, validity dates and approvals — makes knowledge trustworthy enough to feed to AI; Strong European compliance story: ISO 27001, GDPR, EU-only hosting and sovereign or on-premises deployment options; Flexible delivery to people and machines through MCP, APIs, copilots, portals and a browser extension; Multilingual editing and automatic translation suit global, multi-site organizations **Limitations:** AI and workflow depth — MCP connections, approval workflows, gap detection — is reserved for Corporate and above, not the entry Team plan; €15–20 per user per month with a 10-user minimum is a meaningful commitment for very small teams; Enterprise-grade features such as SCIM, advanced security policies and uptime SLAs require a custom contract [Profile (Markdown)](https://openaitools.app/tool/elium-com.md) ## Frequently Asked Questions ### How do ChatPDF and Elium compare in monthly traffic?
