Code box support is native — GPTWeb renders code responses with a dark editor-style background, syntax highlighting (with token color-coding), and mobile-responsive word wrap. Language labels appear in the corner, and visitors can copy-paste directly. Just instruct your AI companion to respond with code when relevant, and the rendering handles itself automatically. Learn more about Knowledge Base (RAG) to power your companion with your own documentation, and explore Agentic Workflow to make your companion proactively engage visitors. Ready to build yours?
