Korrektur, 9. August 2026

. Korrektur: am 9. August 2026 gelöscht funktioniert bei mir nicht mehr Abo gekündigt. Ich vermute die Nutzer Grenzen wurden massiv geändert. Ich hätte zwar noch 2 M Token gehabt, nützt mir aber nichts mehr da die Grenzen massiv geändert wurden, gibt mir keine Antwort mehr aus irgendwelchen Gründen auch immer abgerechnet wird trotzdem.
Da ich die Ursache nicht weiß, nur ein Stern Abzug, musste mir eine andere App zulegen.
Funktioniert noch löschen und Neuinstallation gar nicht mehr. 2M guthaben, die ich noch hatte, sind auch komplett verschwunden. Hab die App wieder gelöscht.
Das mit den automatischen Blocks bei Claude wird erst ab 14. August 2026 eingeführt. Also das dürfte wegfallen, weil der 14. August noch nicht ist.👎

Love it!

I use the app with OpenRouter (BYOK). It’s very flexible, the developer is responsive and supportive. Also I really like the UI and UX. Thank you!

기능 제안

시스템 프롬프트 설정 및 메시지 수정, 재생성 기능이 있으면 좋겠어요!!!

Broken since the update

Every model returns does not support streaming now

The developer who most actively listens to user suggestions!

I emailed the developer suggesting they add a model reasoning effort levels setting, and he quickly implemented this optimization. Now I feel like I can't find a better custom AI assistant than this app!

Best BYOK

Of all the bring your own key this app feels the best so far

越做越差,Azure TTS功能至今没有解决。

对话会混乱

ai对话几次后,回答会混乱,回答的是之前的代码

越做越差,Azure TTS功能至今没有解决。

失望至极!

希望增加修改历史记录的功能

希望增加修改历史记录的功能,至少可以最后一次的对话内容。有时候模型输出不是希望的格式,目前只能一直删除一直生成直到命中,如果能修改会很方便。

Great app. Crashes at times

Coming from Jan, this seems like a great app considering it feels native, fast and syncs with my mobile app

Here are some issues:
1. It used to crash a lot earlier, not these days
2. Projects support is still not there. I occasionally forget what I wrote and grouping them would be helpful.
3. Shortcuts would be a great help for the Mac app

Use this app with caution, as it may steal APIs

My Gemini API is only used for some translation work, and shortly after using OpenCAT, it prompted that the limit had been exceeded.

Please add Vietnamese language to the translation section.

My main use case when using opencat is for translation, as a replacement for the default translation app. So please add Vietnamese to the list.

不支持5.2 pro

Error : This is not a chat model and thus not supported in the v1/chat/completions endpoint. Did you mean to use v1/completions?

垃圾

直接一个垃圾,越来越垃圾

希望增加历史对话导出功能

一直在用,非常好用。更新模型也很及时。不过因为用的多,积累了很多对话内容。希望增加导出的功能,便于搜索特定内容。
