5. Enable the plugin

Manual installation

⚙️ Configuration

API Keys

You'll need at least a Google API Key for image generation. Optionally configure other providers for prompt generation:

Get your API keys:

• Google AI Studio
• OpenAI Platform
• Anthropic Console
• xAI Console

This plugin is free. Image and prompt generation use the API keys you provide, and those providers may charge usage fees.

Network use

This plugin sends the active note's content to the AI providers you configure, so it can generate a prompt and an image. Nothing is sent to the plugin author.

API keys are stored locally in your Obsidian plugin data and are sent only to the matching provider.

Settings

📖 Usage

Generate Knowledge Poster

1. Open a note with content
2. Use Command Palette (Cmd/Ctrl + P)
3. Search for "Generate Knowledge Poster"
4. (Optional) Edit the prompt in preview modal
5. Wait for generation to complete
6. Image will be embedded at the top of your note

Commands

Keyboard Shortcuts

You can assign custom hotkeys in Settings → Hotkeys:

• Search for "NanoBanana" to find all commands

🎨 Image Styles

❓ Troubleshooting

"API key is not configured"

→ Go to Settings → NanoBanana PRO and add your API key

"Rate limit exceeded"

→ Wait a few minutes and try again. Consider upgrading your API plan.

"Content was blocked by safety filters"

→ Modify your note content or try a different style

Image generation fails repeatedly

→ Try regenerating with a different style, or edit the prompt in preview mode

No image in response

→ The model may not support image generation. Try gemini-2.0-flash-exp or similar.
