Japanese Input Bug in Mac Desktop App - Critical Issue for Japanese Users

I am experiencing severe issues with Japanese input on the Mac Desktop App of ChatGPT.

[Specific Issues]

• Characters disappear unexpectedly during conversion

• Unintended line breaks occur after confirming conversion

• Partial text disappears suddenly

These problems only happen in the ChatGPT Mac app.

Other apps (Notes, Word, Mail) work perfectly fine.

I tried both the default macOS IME and Google Japanese Input, but the problem persists.

This critical bug has been left unaddressed for over 3 months since late 2023.


[Serious Complaint from Japanese Users]

Japanese is one of the major supported languages of ChatGPT.

However, OpenAI’s failure to fix this for over 3 months feels like clear neglect toward Japanese users .

This is not a minor inconvenience, but a critical UX failure that breaks the entire typing flow .

If OpenAI fails to clarify a concrete action plan, I will be forced to stop using ChatGPT altogether.


[My Demands]

Immediate investigation and bug fix

Clear action plan with a timeline

Fair quality assurance for Japanese users

I strongly demand OpenAI to respond within a week with your initial action plan.

Neglecting Japanese users any further will seriously damage OpenAI’s credibility.

This is an urgent matter. Please take it seriously.
