Weave's look is configured under Settings → Appearance. Changes apply instantly and persist across restarts.
Theme
Choose Dark (the default), Light, or System (follows your OS). Separate code themes can be set for light and dark so syntax highlighting always looks right.
Text size & scale
Adjust the global text size and overall UI scale. Chat message text can optionally be sized independently of the rest of the interface, so you can make conversations larger without resizing every panel.
Prompts & behavior
Related settings live under Settings → AI, where you can edit the prompts that steer Weave's automated behaviors — the global system prompt, chat titling, the chat-to-weave summary, and how requests are decomposed into tasks. Each falls back to a sensible built-in default when left blank.
