Pros and Cons

Pros:

• Focus: Canvas separates the "chatting" from the "doing," making it easier to refine long documents.
• Health: Dark mode significantly reduces blue light exposure.
• Security: Temporary chats prevent clutter and increase data privacy for sensitive topics.

Cons:

• History Limitations: You cannot retrieve a Temporary Chat once closed.
• Mobile Parity: Canvas features are most powerful on desktop; mobile versions are improving but limited.
• Learning Curve: Users must learn to "highlight and ask" in Canvas rather than just chatting.

Feature Access

Dark Mode & Temporary Chats: Available to all users (Free and Advanced) globally.

Gemini Canvas: Initially an Advanced feature, Google began rolling this out to broader audiences in early 2025.
