Otio is an AI research workspace where users upload and organize large numbers of sources, such as PDFs, articles, videos, and transcripts, and then ask questions across all of them at once. It is aimed at people who do sustained research work, including consultants, lawyers, analysts, journalists, policy professionals, and students, and the site states it is used by more than 200,000 professionals across dozens of languages.
Unlike a chat tool that starts fresh each session, Otio keeps a persistent, searchable library that keeps growing as a user adds more material over months, so someone can upload dozens of papers in one project and keep querying that whole set later on. Answers come with citations down to the specific page and passage they are drawn from, and the workspace lets a user chat through more than one underlying AI model from a single interface rather than switching between separate tools. Sources can be organized into separate projects to keep different pieces of research apart.
Otio is free to start, with its full feature set and AI models included at that level; a paid tier exists for additional usage, though specific pricing beyond the free plan is not detailed on the site.
