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) ## Haye Haye is a desktop AI companion built specifically for macOS users who want a fast, native way to work with large language models. Instead of juggling browser tabs for ChatGPT, Claude, Gemini, and DeepSeek, Haye gathers them into one clean client. A system-wide shortcut (Command+E) summons the assistant on top of whatever app you are using, so you can highlight text or drop in a screenshot and get an answer without breaking your flow. The app leans on a "chat with anything" philosophy: PDFs, local documents, images, and web pages can all become conversation partners. Haye can run web searches and return answers with source links, compare responses from several models side by side, and adapt to your preferred writing style through customizable chat rules and preferences. It also supports bring-your-own API keys, so power users can route requests through their own OpenAI, Anthropic, Gemini, DeepSeek, or OpenRouter accounts. Haye is distributed as a downloadable macOS application (supporting both Apple Silicon and Intel Macs) rather than a web service, and it emphasizes privacy by keeping generated data local and not accessing user content. Pricing blends a free trial with a one-time lifetime license and an optional Pro subscription that bundles premium model access. **Pricing & Plans:** Freemium. A free trial offers limited quota with basic models. A one-time lifetime purchase (~$19.99) unlocks Haye 2 features and custom model configuration, while a Pro subscription (~$4.99/month) adds premium AI service access and multi-device support. - **Global shortcut access:** Press Command+E anywhere in macOS to invoke Haye over the current app, or trigger it directly from selected text. - **Multi-model chat:** Chat with and compare answers from top models such as GPT, Claude, DeepSeek, and Gemini in a single interface. - **Chat with files and PDFs:** Ask questions about PDFs, screenshots, images, and local documents through natural conversation. - **Web search with sources:** Get timely answers with linked web sources instead of relying solely on a model's training data. - **Custom model and style rules:** Bring your own API keys, define reusable chat styles, and fine-tune language, tone, and model preferences. **Strengths:** Native macOS feel with an unobtrusive global shortcut; Genuinely useful for PDF and screenshot Q&A; Supports your own API keys alongside built-in access; One-time lifetime license option instead of forced subscription **Limitations:** macOS only — no Windows, Linux, Android, or iOS builds yet; Memory and context features were still listed as planned in the future; Free tier is limited in quota and model choice [Profile (Markdown)](https://openaitools.app/tool/haye.md) ## Frequently Asked Questions ### How do ChatPDF and Haye compare in monthly traffic?
