Otio AI

AI-driven tool for document summarization, interaction, and workflow automation

Otio AI gives researchers, students and professionals a workspace for reading and questioning hundreds of sources at once. PDFs, web pages, YouTube videos, podcasts and transcripts go into one library, and you can chat across them using multiple AI models, with answers cited at page level. The site also lists OCR and PDF extraction, book and textbook summarizers, a spreadsheet AI and data visualization features.

Beyond summarizing, Otio positions itself as a way to turn a reading backlog into a structured starting point for writing, with a text editor and essay-writing support built in. Integrations listed on the site include Zotero, Dropbox, OneDrive and Box, and there are dedicated use cases for legal research, financial analysis, medical students, ESG analysts and policy professionals.

As a research tool, it fits anyone who needs to keep large numbers of sources in one place and ask questions across them rather than reading each in full. Otio offers a free tier with paid plans; sign up for the free option and test it on a batch of your own PDFs and videos before committing.
