Claude Pruner
A web-based tool for selectively pruning and exporting conversations from Claude.ai, including messages, artifacts, tool usage, and thinking steps.
Overview
Claude Pruner provides a detailed, interactive view of a Claude.ai conversation, allowing you to deconstruct it into its core components. The tool receives conversation data from a companion bookmarklet and organizes it into two columns: one for human/assistant messages and “thinking” blocks, and another for generated artifacts and tool usage. You can then select precisely which parts of the conversation you want to keep and export them as a clean, structured text file.
Features
- Detailed Conversation View: Separates a conversation into messages, artifacts (e.g., code blocks), tool use/results, and “thinking” steps.
- Granular Selection: Individually select or deselect any component of the conversation.
- Bulk Toggling: Quickly toggle the selection state for all human messages, assistant messages, artifacts, tools, or thinking blocks.
- Usage Statistics: Provides a running total of selected items, word count, and estimated token count for the pruned conversation.
- Flexible Export: Copy the formatted selection to your clipboard or download it as a
.txt file.
- Privacy-Focused: All processing happens entirely in your browser. No conversation data is ever sent to a server.
Usage
This tool is designed to be used with its companion bookmarklet.
- Install the Claude Pruner bookmarklet in your browser using the Bookmarklet Installer.
- While on an active conversation page on
claude.ai, click the bookmarklet.

Technical Details

claude.ai domain via the window.postMessage API.
- Dynamically parses the JSON data structure and renders the interactive UI.
- Sorts all selected components chronologically in the final exported output.
