Chat with PDFs, papers & notes
Free · In-App Purchases
Meet Otio, your AI research workspace for turning PDFs, links, notes, and files into answers, summaries, and drafts.
Otio helps you bring scattered PDFs, links, notes, files, and recordings into one connected research library. Ask questions across your materials, generate summaries and drafts, and organize work into focused Spaces with AI chats that understand your context.
With Otio in your pocket, you can:
· Ask questions across your research library and get answers grounded in your sources, with citations you can tap.
· Upload PDFs, Word documents, EPUBs, links, notes, images, audio, and videos.
· Chat with selected files, links, or notes to explore specific materials in depth.
· Summarize long papers, reports, articles, transcripts, and saved web pages.
· Generate outlines, briefs, study notes, and first drafts from your research.
· Search the web inside Otio — read pages, save sources, and bring them straight into chat.
· Organize work into color-coded Spaces for papers, clients, classes, projects, and topics.
· Import files from Google Drive, Dropbox, Box, OneDrive, Mendeley, Zotero, and Telegram.
· Choose from top AI models — GPT, Claude, Gemini, Grok, DeepSeek, and more.
· Listen to AI answers with built-in Read Aloud.
· Generate AI images and edit them in the same chat.
