arena.ai / LMSYS Arena Chat Exporter

Export your arena.ai, lmarena.ai, and legacy LMSYS Arena (chat.lmsys.org, arena.lmsys.org) chat history as JSON or readable TXT.

Features

  • Export the current chat as JSON or TXT
  • Load your chat history list inside the page
  • Select specific chats or select all
  • Export multiple chats at once
  • Automatically package multi-chat exports into a single ZIP
  • Readable ASCII-style TXT export for quick archiving
  • English / Chinese UI
  • Low-intrusion floating panel with a neutral glass style

Export formats

JSON

Best for:

  • Full archival
  • Programmatic processing
  • Keeping the original response structure

TXT

Best for:

  • Human reading
  • Quick browsing
  • Lightweight offline notes

TXT output is intentionally simplified. If you need the complete raw structure, use JSON.

How to use

  1. Open any arena.ai, lmarena.ai, or legacy LMSYS Arena chat page
  2. Click the small docked export button on the right side
  3. Export the current chat directly, or load the history list and batch export selected chats

Search aliases

  • arena.ai
  • lmarena.ai
  • LMSYS Arena
  • chat.lmsys.org
  • arena.lmsys.org
  • chat history downloader
  • chat exporter

Notes

  • The script uses your existing logged-in browser session
  • Batch export uses in-browser ZIP packaging
  • The history list loads page by page until the API reaches the end
  • A high safety guard is kept internally to avoid infinite pagination if the site changes

Privacy

This script runs locally in your browser. It does not upload your conversations anywhere by itself.
