    General guidance from repository metadata, not legal advice. How we score

    From the README

    A drop-in replacement for react-markdown, designed for AI-powered streaming.

    Formatting Markdown is easy, but when you tokenize and stream it, new challenges arise. Streamdown is built specifically to handle the unique requirements of streaming Markdown content from AI models, providing seamless formatting even with incomplete or unterminated Markdown blocks.

    Streamdown powers the AI Elements Message component but can be installed as a standalone package for your own streaming needs.
