Otio

Otio is an AI-powered platform designed to assist researchers and professionals in understanding, summarizing, and interacting with various digital sources like documents, links, and videos. It provides tools for automatic summarization, AI-driven chat with content, and an AI text editor for drafting and refining written work, aiming to streamline research and writing workflows.

Otio is an AI research and writing partner that allows users to import various sources, including links and documents, for summarization, chatting, and AI-assisted writing. It offers a Chrome extension for saving links, which are then automatically organized and summarized. While it doesn't explicitly mention 'sections' within lists or 'Tufte-style side notes,' it does organize content and allows for AI-driven interaction with the content, which can serve a similar purpose to contextual notes. Public sharing of curated lists is not a primary feature, as its focus is more on personal research and writing.
