Frequently Asked Questions

General

Is PandaNpc free?

Yes, PandaNpc's core features are completely free. You can use AI chat, notes, SSH terminal and more at no cost. Advanced features and premium AI models can be unlocked with credits.

Do I need my own API Key?

No. PandaNpc includes a built-in AI proxy service — you don't need to register or manage API keys yourself. However, you can optionally add your own providers and API keys for unlimited usage.

Which platforms are supported?

PandaNpc runs on Windows 10+, macOS 11+ (Apple Silicon), and Linux (Ubuntu/Debian x86_64).

AI Chat

Which AI models are supported?

Built-in support for three major providers: OpenAI (GPT-5, GPT-5.2, GPT-5.2 Codex), Anthropic (Claude Opus 4.6, Sonnet 4.5, Haiku 4.5), and Google (Gemini 3 Pro, Gemini 3 Flash). You can also add custom providers.

Can I use multiple models in one conversation?

Currently, each conversation uses one model at a time. You can switch models between conversations, or start a new conversation with a different model to compare responses.

Does it support image input?

Yes! You can drag and drop images into the chat, or paste images from clipboard. Models with vision capability (like GPT-5.2, Claude Opus 4.6, Gemini 3 Pro) will analyze the image content.

What is streaming response?

PandaNpc shows AI responses in real-time as they are generated, word by word. This means you don't have to wait for the full response — you can start reading immediately.

Notes

How do I save a chat response to notes?

Hover over any AI response message and click the "Save to Note" button that appears. The content will be saved to your note editor where you can further edit and organize it.

What formats does the note editor support?

The rich-text editor supports: text formatting (bold, italic, headings), code blocks with syntax highlighting, images, tables, lists, and more.

Data & Security

Is my data secure?

PandaNpc uses end-to-end encrypted transmission for API requests. Conversation data is stored locally on your device — we do not store or access your conversations on our servers. Your privacy is our top priority.

Can I export my data?

Conversations and notes are stored locally. You can find them in the application data directory. Export functionality is planned for a future release.

Performance

Why is PandaNpc so fast?

PandaNpc uses a custom high-performance rendering engine built with Rust WASM for Markdown parsing, virtual scrolling for handling large conversation histories, and DOM pooling to minimize memory usage. This architecture delivers consistent 60 FPS performance even with tens of thousands of messages.

How much memory does it use?

PandaNpc uses approximately half the memory of comparable Electron-based AI chat clients, thanks to its native Tauri framework and optimized DOM management.
