More trust and onboarding components

  • AI-Generated Label

    A clear label that marks text or images made by AI. Hover or focus it to see how it was made and what to check.

  • AI Disclaimer Banner

    A short, honest notice that the assistant can make mistakes, with a link to learn more. It can be closed and remembers that choice.

  • Onboarding Tour

    A step by step tour that points at parts of the app with short tips. People can go back, skip, or use the arrow keys.

  • Prompt Tips Card

    Tips for writing better prompts, each with a weak and a stronger example side by side. Flip through them with the arrows.

  • Keyboard Shortcuts Panel

    A panel of keyboard shortcuts that opens with the question mark key, with a search box and keys grouped by task.

  • AI Error States

    Friendly error screens for common AI problems: no internet, the service is busy, and a message that is too long. Each says what to do next.
