13 | 
14 | ## Introduction
15 | 
16 | Claude Artifact Downloader is a Chrome extension designed to enhance your experience with the Claude AI chat interface. It allows users to easily download all artifacts (code snippets, diagrams, etc.) generated during a conversation with Claude as a single ZIP file. This tool is particularly useful for developers, researchers, and anyone who frequently uses Claude for generating or discussing code and other technical content.
17 | 
18 | > This project was inspired and uses some code snippets from https://github.com/hamelsmu/claudesave. Thank you Hamel and other authors.
19 | 
20 | ## Features
21 | 
22 | - Adds a "Download Artifacts" button directly to the Claude chat interface
23 | - Extracts all artifacts from the current conversation
24 | - Packages artifacts into a single ZIP file for easy download
25 | - Preserves the chronological order of artifacts
26 | - Handles duplicate artifact names with intelligent suffixing
27 | - Assigns appropriate file extensions based on content type
28 | 
29 | ## Installation
30 | 
31 | To install the Claude Artifact Downloader extension:
32 | 
33 | 1. Clone this repository or download the source code.
34 | 2. Open Google Chrome and navigate to `chrome://extensions`.
35 | 3. Enable "Developer mode" using the toggle switch in the top right corner.
36 | 4. Click "Load unpacked" and select the directory containing the extension files.
37 | 5. The extension should now appear in your list of installed extensions.
38 | 
39 | ## Usage
40 | 
41 | 1. Navigate to the Claude AI chat interface (https://claude.ai).
42 | 2. Start or continue a conversation with Claude.
43 | 3. When you're ready to download artifacts, look for the "Download Artifacts" button in the chat interface (usually near the top of the page).
44 | 4. Click the "Download Artifacts" button.
45 | 5. The extension will process the conversation and generate a ZIP file containing all artifacts.
46 | 6. Choose a location to save the ZIP file when prompted by your browser.
47 | 
48 | ## Project Structure
49 | 
50 | The project consists of the following key files:
51 | 
52 | - `manifest.json`: Defines the extension's properties and permissions.
53 | - `background.js`: Contains the main logic for extracting and processing artifacts.
54 | - `content.js`: Handles the injection of the download button into the Claude interface.
55 | - `jszip.min.js`: Third-party library for creating ZIP files in the browser.
56 | 
57 | ## How It Works
58 | 
59 | 1. The extension adds a "Download Artifacts" button to the Claude chat interface.
60 | 2. When clicked, it extracts the conversation UUID from the current URL.
61 | 3. It then retrieves the chat data from Chrome's local storage.
62 | 4. The chat messages are processed recursively, starting from the most recent root message.
63 | 5. Artifacts are extracted from each message using regular expressions.
64 | 6. Each artifact is added to a ZIP file with a unique filename based on its title, language, and message index.
65 | 7. The ZIP file is then offered for download.
66 | 
67 | ## Contributing
68 | 
69 | Contributions to the Claude Artifact Downloader are welcome! If you'd like to contribute:
70 | 
71 | 1. Fork the repository.
72 | 2. Create a new branch for your feature or bug fix.
73 | 3. Make your changes and commit them with clear, descriptive messages.
74 | 4. Push your changes to your fork.
75 | 5. Submit a pull request with a description of your changes.
76 | 
77 | Please ensure your code adheres to the existing style and includes appropriate comments.
78 | 
79 | ## Troubleshooting
80 | 
81 | - If no artifacts are found, try refreshing the Claude chat page and attempting the download again.
82 | - Ensure you have the latest version of Google Chrome installed.
83 | - If you encounter any issues, check the browser console for error messages and report them in the project's issue tracker.
