Claude Conversation Exporter

A Chrome extension that allows you to export your Claude.ai conversations in various formats (JSON, Markdown, Plain Text) with support for bulk exports and conversation browsing.

Features

• 📥 Export Individual Conversations - Export any conversation directly from Claude.ai
• 📚 Bulk Export - Export all or filtered conversations as a ZIP file
• 🔍 Browse & Search - View all your conversations in a searchable table
• 🌳 Branch-Aware Export - Correctly handles conversation branches (exports only the current branch)
• 📝 Multiple Formats - JSON (full data), Markdown, or Plain Text
• 🗂️ ZIP Archives - Bulk exports create organized ZIP files with all conversations
• 🏷️ Metadata Options - Include or exclude timestamps, models, and other metadata
• 🤖 Complete Model Information - Preserves and displays model information for all conversations (unlike official Claude.ai exports)
• 🔮 Smart Model Inference - Automatically infers the correct model for conversations that used the default model at the time

Why Export Your Claude.ai Conversations?

Beyond just backing up your data, there are compelling reasons to export your conversations:

1. Access to Discontinued Models

Some older Claude models (like Claude 3 Sonnet and Claude 3.5 Sonnet) are no longer available on Claude.ai but remain accessible through APIs. By exporting your conversations, you can continue them using these models through other interfaces.

2. Overcome Context Limitations

Claude.ai doesn't allow you to continue conversations after hitting context length limits. Other applications can implement:

• Rolling context windows - Automatically manage context to continue indefinitely
• Context compression - Summarize earlier parts to fit more conversation
• Selective context - Choose which parts of the conversation to keep in context

3. Escape Platform Restrictions and "Long Conversation" Injections

Claude.ai uses a fixed system prompt and injects "reminders" that include certain behavioral rules. Recent updates have added restrictions that some users find limiting, such as:

• Injunctions against Claude discussing its inner experiences or consciousness
• Specific formatting restrictions
• Behavioral constraints that may not align with all use cases

With exported conversations, you can continue them in environments with different or customizable system prompts. Using the Anthropic API instead of Claude.ai also avoids "long_conversation_reminder" injections, though it doesn't avoid all injections.

4. Enhanced Features in Other Apps

Many third-party applications offer features not available on Claude.ai:

• Custom system prompts
• Multi-model conversations
• Integration with external tools and APIs

5. Data Ownership and Portability

Your conversations are valuable intellectual property. Exporting ensures you:

• Own and control your data
• Can migrate between platforms
• Won't lose access if policies change
• Can analyze your conversation patterns and history

Advantages Over Official Claude.ai Export

This extension provides several advantages over the official Claude.ai data export:

1. Model Information Preserved: The official export doesn't include which model (Claude 3, 3.5, Opus, Sonnet, etc.) was used for each conversation. This extension preserves and displays this crucial information.

2. Historical Model Inference: For conversations that used the default model (which shows as null in the data), the extension intelligently infers which model was actually used based on when the conversation occurred and Anthropic's default model timeline.

3. Instant Export: No waiting for email delivery - export conversations immediately.

4. Flexible Formats: Choose between JSON, Markdown, or Plain Text formats based on your needs.

5. Selective Export: Export individual conversations or filter by model, date, or search terms.

6. Better Organization: Conversations are exported with meaningful filenames and can be bulk exported into organized ZIP files.

Chrome Web Store Submission

To prepare for Chrome Web Store submission:

1. Create a ZIP for Submission

cd claude-export
zip -r claude-exporter.zip claude-exporter/ -x "*.DS_Store" -x "*/.git/*"

2. Prepare Store Listing Assets

You'll need:

• Screenshots (1280x800 or 640x400): Take screenshots of the extension in action
• Promotional Images: Small tile (440x280), Large tile (920x680) - optional
• Description: Use the features list from this README
• Category: Suggested: "Productivity" or "Developer Tools"

3. Privacy Policy

Since the extension accesses Claude.ai data, you should mention:

• The extension only accesses data when explicitly triggered by the user
• No data is sent to external servers
• All processing happens locally in the browser
• User's Claude.ai authentication is used only for API access

4. Permissions Justification

Be ready to explain why each permission is needed:

• activeTab: To interact with the current Claude.ai tab
• storage: To save user's organization ID
• scripting: To inject content scripts for export functionality
• Host permission for claude.ai: To access Claude.ai API endpoints

Troubleshooting

"Organization ID not configured"

• Follow the setup steps in the Configuration section
• Make sure you're copying the complete UUID from the URL

"Not authenticated" error

• Make sure you're logged into Claude.ai
• Try refreshing the Claude.ai page

Export fails for some conversations

• Some very old conversations might have different data structures
• Check the browser console for specific error messages
• The ZIP export includes a summary file listing any failed exports

Content Security Policy errors

• Make sure you're using the latest version of the extension
• Try reloading the extension from chrome://extensions/

Privacy & Security

• Local Processing: All data processing happens in your browser
• No External Servers: The extension doesn't send data anywhere
• Your Authentication: Uses your existing Claude.ai session
• Open Source: You can review all code before installation

Known Limitations

• Plaintext and markdown formats only export the currently selected branch in conversations with multiple branches
• Large bulk exports may take several minutes
• Some special content types (like artifacts) may not export perfectly
• Rate limiting: The extension processes conversations in small batches to avoid overwhelming the API
