Overview

What is Otio AI?

Otio is presented as an AI research workspace that brings together PDFs, web pages, videos, audio, spreadsheets and notes in a single environment. It focuses on turning diverse sources into answers, summaries, drafts and structured outputs, with an emphasis on working directly from user-provided material rather than generic web chat. The product highlights multi‑model support, cited questioning, autonomous web research and a shared source library that keeps all materials connected. A recurring theme on the official site is that Otio is designed to work with existing sources, not around them, and to make deep research, synthesis and writing faster while maintaining clear links back to the underlying documents.
