Useless social media-ized antonation tool. You literally cannot even antonate or highligth local files without creating an account. Dev needs to clearly state their niche on app page, because this was a waste of 20 mins of my life

Great app but my chrome extension keeps logging out way too frequently somehow. Every time I want to add a bookmark, I've to go through the singin flow again which is really frustrating. I've added the exception to allow cookies from the extension as well but using an add blocker, maybe that's why.

This is a "social" annotation tool. Which is a weird thing. It makes your annotations public (for some reason) by default and accidental clicks show you every other user's annotations (for some reason). Collaboration makes sense, but this vast social media approach is bizarre and distracting, and it seems this is mostly a social media ap for discussing articles with every other user. The steps to make things private are unintuitive and awkward, and the labels in this regard are contradictory (eg your annotation will say "public" but with a lock icon, which means it's in a public sphere, but locked from view. Disconcerting.) There are other similar aps without the social media aspect whose features are similar.

I wish it had a underlining feature, because personally for me underlining and highlighting are two different methods of annotating for me so i think it'll be a perfect addition to the extension

Updated review: From 3 stars to 1. DO NOT USE. I spent HOURS going through and making notes on dozens of pages (an annoying, inefficient process as detailed below) yesterday, only to go back to it today, without even having closed the browser or the tabs in the meantime, and ALL but ONE page has lost the annotations. If I search for them, or for any done by me, it's the only one that comes up. So HOURS of work gone. This "service" is garbage and should NOT be used. Consider yourself warned. It's nice being able to annotate, but has issues. Can't set to always show notes (have to either leave the sidebar open or manually open it each time, instead of being able to keep note visible in corner), constantly having to log back in, which is both annoying and can cause issues, have to manually enable it on each and every page, even within the same site, and after having to log back in this last time every time I tried creating an annotation it would increment the counter number but not let me type anything, until I refreshed the page. Also, it reverts back to public instead of staying on private as set (or allowing a default to be set). Much potential brought down by poor design and possible bugs.

I tried and used hypothes.is a year or two ago (along with every other note taking \ pkm \ bookmark tool \ extension in the world ... i finally gave up and went to (try to) use worldbrain Memex and then Obsidian, and then, frankly gave up, and just used OneTab. Lately i started trying to come up with "a plan" again. Memex with Logseq, sorted and organized tab groups to Tab++ and whole sessions saves to OneTab ... the bulk of it happens between Memex and Logseq. Memex recently went paid (for more than 50 uses per month) so i went back to searching. Tried this again. Its MUCH better now. Feels smoother, tighter, more in the right place stuff, less in the wrong place. Great features. Private notes (finally?) ... integrates with Logseq. Will be using this and Logseq now, with tabmanager back ups just to be safe. But a FULL TEXT SEARCHABLE annotation (and defacto bookmark) service with a graph capable PKM (logseq) is THE TICKET. If Hypothes.is ever beefs up their note taking capabilities, it will be untouchable. HELL YEAH!

This extension does one extra thing that other extensions doesn't. The option to temporarily hide all the annotations/highlights on the page. I don't know why other extensions overlooked this simple to implement feature. Thanks for this feature. Improvements: More variations of color. Its a bit bland right now.

Keeps logging out. After each refresh of page I have to login again. After logging in I have to change "group".
