pdfy.ai vs Doclime

pdfy.ai lets you chat with PDFs, websites, audio files, and YouTube videos instead of reading or scrubbing through them yourself. Upload a source, ask questions in plain language, and get answers drawn from the content. It is built for anyone who needs facts from long documents or media without sitting through every page or minute.

The app targets dense material like 200-page textbooks, meeting recordings, lengthy Wikipedia articles, and multi-hour video tutorials. You can ask follow-up questions and see where answers came from, which helps when you need to quote a source in school or at work.

Sign up, upload a file by drag-and-drop or file picker, and start chatting. Questions go into a simple chat box, and responses come back based on what the uploaded source contains.

Doclime lets you upload PDFs and ask questions that come back with cited answers pulled from the file. You get a built-in PDF viewer with search and page navigation, a notes editor with version history, and a split-screen layout that keeps chat, documents, and notes open at once. It also reads scanned PDFs through OCR and accepts screenshot questions through its Vision feature.

Most PDF chat tools stop at a single file and a text box. Doclime stacks a hierarchical file tree, multi-document context for one conversation, and frontier models from OpenAI and Anthropic in the same workspace. That combination targets people cross-referencing textbooks, contracts, or research papers rather than doing one-off summaries.

The homepage lists use cases like lesson planning from textbooks, chapter summaries, and pulling obligations from contract sections, with example answers showing bracketed source references. Stanford, Berkeley, Cornell, and USC logos appear on the landing page, and the interface ships in nine languages including English, Spanish, French, German, Japanese, Korean, Arabic, and Chinese.
