Confidence Ink

AI chats

About

A text display that renders AI-generated answers with per-word confidence, dimming words the model was unsure of and letting a reader open any uncertain word to see the alternatives it nearly chose, with their odds, and swap one in.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Confidence Ink to your project and fits it to your theme.

How Confidence Ink is used: the demo's code. The component's own source comes with a free account.
