LLM Chat Replay is a React application for visualizing chat transcripts from LLM sessions. It lets you replay conversations with typing animations and playback controls.
To use it, first set up an MCP filesystem server. Then, save your chat as a markdown file and upload it to the application for playback.
Key features include drag-and-drop for .md file upload, playback controls (play/pause), speed adjustment from 0.5x to 4x, a scrubbable progress bar, and an auto-scrolling chat window. It displays messages in distinct bubbles for Human: and Assistant:, with typing animations for Assistant responses.
Use cases include reviewing past LLM conversations for clarity, analyzing chat interactions for research, and creating educational content from transcripts.
It supports markdown files formatted with Human: and Assistant: markers. You need to set up an MCP filesystem server and install its dependencies. The tool is open-source and free to use.
