Chat with any PDF, video, or website and get cited answers in seconds
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.
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.
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.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
Private AI that answers from your own documents, on Mac and Windows
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.
Every response cites the underlying file plus the page, slide or sheet it came from, so you can open and verify the passage yourself.
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.
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.
