Claude Chat Exporter 作者： ZAX

Export a Claude.ai conversation to a nicely-formatted .txt file.

A minimal, dependency-free Firefox extension that adds an export button to Claude.ai. One click saves any conversation as a plain-text .txt file.

What it does

• Injects a small icon button directly below Claude.ai's built-in Share button on every conversation page.
• Clicking it downloads the current conversation as a plain .txt file, with clearly-separated USER and ASSISTANT sections wrapped in Unicode boxes.
• Code blocks are preserved with 4-space indentation for monospace readability.
• The filename includes the conversation title and timestamp, so exports sort naturally in your Downloads folder.

What it does NOT do

• No data collection. Nothing leaves your browser. No telemetry, no analytics, no remote requests.
• No background page, no service worker, no remote dependencies. A single hand-written content script that runs only on claude.ai.
• No tool calls / extended thinking / artifacts in this version — only the conversation text is exported. These may become opt-in toggles in a future release.
