Hypothesis - a public-by-default web annotation tool 預設公開的網上標註筆記工具

A flexible online highlighting, note-taking, and sharing app. What sets it apart from Omnivore and Glasp is that you get to control each note's visibility: by default all notes are public and published, but you can make a note private, viewable to you only, by either creating it in a private group or setting it to "to me only" in a (default) public group. I tested this and it works as claimed.

Anyone can read and search for a public note without a Hypothesis account.

Hypothesis doesn't compete head-on with Omnivore because it isn't also a reading app, but in my opinion it kind of eats Glasp's lunch simply by having a functioning Obsidian plugin that syncs to Obsidian, like Omnivore does. However, Glasp uniquely offers a very cool capability of video annotations for YouTube. (2023-12-16) YouTube annotation is now possible with Hypothesis, for videos that have subtitles at least. #todo Test videos with purely Chinese subtitles.

This tool seems rather popular with teachers and students because it integrates with learning management platforms like Canvas.

Quick verdict: 4.5 stars 強力推薦



These two problems with Hypothesis may nudge me into trying out Reader to see if its sync is always complete and covering updated highlights and annotations.
