What's New in Cubox

8.3.1

September 21, 2026

* New Cover Gallery cards: Browse your saves with large cover images for a more relaxed experience, and find articles you’ve read more easily by visual memory. * Apple Watch improvements and fixes: Bring your highlights to more watch face complications. Glance at excerpts while commuting or waiting in line, without reaching for your phone. You can now also send a reminder to your iPhone with one tap, then open the notification to jump straight to the highlight and continue reading in context. * Spotlight Search fixes for iOS/macOS 27: Search your Cubox saves right from the Lock Screen or Home Screen by typing “cb + keyword,” without opening the app. You can also customize the search keyword in Cubox Settings. * Annotation card improvements: Annotation cards now expand to fit their content, so longer passages are displayed more completely. * Refined details across global theme colors. * Fixed more issues with overall stability improvements.

小红书无法解析

已经用了很久了,喜欢将小红书的帖子直接解析为图文长文模式,这个功能从前段时间某天开始完全不能使用了,解析出来的内容不再包含图片,而且标题和内容也很随机乱码……

CLI doesn’t work; upload doesn’t work from desktop; constantly a security threat

The newsletter feature didn’t work for me as described; the helper function doesn’t work; considering its safari extension is always asking for access to everything in addition to the fact that its terms and conditions expressly state that you have no right to any privacy in your information if such information would violate Chinese laws, I uninstalled and stopped using it despite having paid for a full year subscription

i wanted to like it

seems to have a terrific use case but does not work on ios with file attachments; worse, app support provides zero… support

TTS for 5 Stars

The not-a-pocket replacement I didn’t know I needed. Local TTS functionality would put it clear of all others.

Unbelievable App

Easily one of the top 5 second brain apps on the market and may very well be the best overall productivity tool
