Google gives Gemini image markup tools to stop the app from guessing

Using the new Gemini 3 and Nano Banana Pro models in the Gemini app. .

What you need to know

• Gemini now lets you draw directly on images, so you can show the AI exactly what you mean instead of overexplaining in text.
• You can circle, highlight, sketch, or add notes, and Gemini uses those markings as context for analysis or edits.
• This appears to be a quiet server-side test, so you might not see the new tools immediately even if your app is updated.
