Overview

Otio AI handles the reading backlog stage of research. A user collects papers, articles, videos and links, and the assistant summarises across the whole collection, answers questions spanning sources, and helps turn the result into written output. Working over hundreds of sources at once is the differentiator from chat tools that handle one document per conversation.

Because the library persists, the same corpus supports repeated questions over months rather than being re-uploaded per session. For a thesis or a long report, that continuity is the value.

Cross-source synthesis needs verification against the originals before anything is cited, since attribution errors are the common failure in this category. Otio keeps source links attached, which makes checking practical. A free tier exists, with paid plans by usage.
