Appearance Settings

Theme, language, text size, and the send key

Under “Personal > Theme & Language” in Settings, you can adjust how the app looks.

Theme

Option	Description
Light	Bright color scheme (default)
Dark	Dark color scheme
System	Follows your OS setting automatically

Language

Choose the app’s display language: 日本語 / English.

This setting changes the display language of the interface. In chat, the AI generally responds in the language you write in (an explicit instruction always wins).

If you have never chosen a language here, sending a prompt in Japanese triggers a one-time banner offering to switch the interface to Japanese — accept to switch, or decline to keep the current language. Once you pick a language here, the banner never appears.

Text size

Choose the app-wide text size: Small / Standard / Large. Spacing scales proportionally to keep the layout balanced. Browser zoom (⌘/Ctrl + + / -) works alongside it.

Sending messages

Choose which key sends a chat message — the other inserts a line break.

Option	Behavior
Enter (default)	Enter sends; Shift + Enter inserts a newline
⌘ / Ctrl + Enter	⌘ / Ctrl + Enter sends; Enter inserts a newline

• ⌘ / Ctrl + Enter always sends in both modes, and the choice is saved per device
• On phones and tablets, Return inserts a line break by default, regardless of the option above. Touch devices additionally show a “Keep this behavior on touch screens” checkbox that applies your chosen send key (“this behavior”) to the touch device as well — turn it on for a tablet with a hardware keyboard
