# Otio

> An AI research workspace for source-heavy work — researchers, PhD students, journalists, consultants, and anyone working with a lot of sources. Upload PDFs, web pages, YouTube videos, podcasts, or notes; chat across all your sources with any AI model (Claude, GPT, Gemini, Otio Auto); every citation traces back to the exact page.

Otio is built by Frontdoor Labs Ltd (London). Around 200,000 people use Otio globally across web, desktop (Electron), and iOS.
