What's New in Cubox

8.3.0

September 10, 2026

Cubox now fully supports iOS, iPadOS, and macOS 27, with app-wide themes and a range of updates for a better reading experience. - Your reading theme now extends throughout Cubox, complementing your custom Liquid Glass effects. - Updated tab bar search, navigation bar scroll edge effects, and sidebar behavior in split view on iPad and Mac for the new OS releases. - Improved the reliability of text highlighting and note menus. Selecting text from the left edge is now less likely to trigger back navigation. - Improved AI insights and Q&A, with clearer generation controls and more reliable streaming responses. - Fixed an issue where tapping a reader highlight sometimes failed to open its menu. - Fixed how saved items with parsed content but no title are displayed, removing unnecessary prefixes. - Refined interface contrast, theme switching, and other interaction details.

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
