ChatGPT Message Saver

Original core idea inspired by Arian Jahed – https://github.com/C0deforbreakfast

Save, organize, and jump back to specific user prompts in ChatGPT conversations. Adds a small save icon next to each of your messages; the popup shows a professional list with copy / open / delete actions, deep-link highlighting, and theme toggle.

Available in firefox addons: https://addons.mozilla.org/en-US/firefox/addon/chatgpt-message-saver/

Features

Current implemented capabilities:

• Save any user message (💾 button injected beside each prompt)
• Popup UI: dark/light themes, copy link, open in same tab or reuse existing tab, delete bookmarks
• In-page jump/highlight when opening a bookmark from the same conversation (no reload)
• Persistent theme selection (stored locally)
• Snippet trimming and timestamp display

How It Works

1. The content script scans ChatGPT (chat.openai.com / chatgpt.com) user messages and injects a save button.
2. Clicking the button stores a bookmark (id, conversation URL, index, snippet, createdAt) in storage.local.
3. The popup lists bookmarks (newest first). Clicking:
   • Row / Copy (⧉): Copies a deep-link URL (#gpt-saver=<id>)
   • Open (↗): Navigates existing ChatGPT tab or jumps in-page if already on that conversation
   • Delete (✕): Removes the bookmark
4. Deep-link handling and in-page message jumping rely on the content script matching snippets / stored index.

Installation (Developer Mode)

Chrome / Chromium:

1. Clone or download this repository.
2. Visit chrome://extensions.
3. Enable Developer Mode (top-right toggle).
4. Click “Load unpacked” and select the project folder.
5. Open ChatGPT and start saving messages.

Firefox:

1. Open about:debugging#/runtime/this-firefox.
2. Click “Load Temporary Add-on”.
3. Select manifest.json from the folder.

Permissions Explanation

storage – Persist bookmarks. tabs – Reuse existing ChatGPT tab, update URL, send in-page jump message. Host permissions (*://chat.openai.com/*, *://chatgpt.com/*) – Inject content script only where needed.

Data Stored

All bookmark data lives in browser.storage.local / chrome.storage.local under the key bookmarks. No remote sync yet.

Bookmark object shape:

{
	id: string,
	conversationUrl: string,       // Base URL of the conversation
	index: number,                 // Message position at capture time
	textSnippet: string,           // Trimmed snippet (<= 120 chars)
	createdAt: number              // Epoch ms
}

Development Notes

• Manifest Version: currently MV2 for simplicity; Chrome MV3 migration is recommended soon (service worker instead of background page if one is added later).
• Popup uses simple vanilla JS; no build tooling required.
• Cross-browser API shim: const ext = typeof browser !== 'undefined' ? browser : chrome.

Roadmap / TODOs

Nearest planned improvements (from user requests):

• Grouping: Allow folders / tags / conversation grouping to organize bookmarks
• Coloring: Color-code bookmarks by tag or manual label (e.g., priority / topic)
• Chrome (Enhancements): MV3 migration + optional sync storage + options page for preferences
• Search / filter bar in popup
• Bulk operations (multi-select delete / export)
• Export / import (JSON file)
• Sort modes (Oldest, A–Z by snippet, Conversation order)
• “Pin” feature (keep certain bookmarks at top)
• Undo for delete (toast with 5s undo action)
• Optional automatic tag suggestion based on snippet keywords
• Sync storage toggle (use chrome.storage.sync / browser.storage.sync when available)
• Keyboard shortcuts: quick save (e.g., Alt+S) and open popup (extension commands)
• Logo

Contributing

1. Open an issue describing improvement / bug.
2. Submit PR with focused changes (avoid unrelated formatting).
3. Keep styles consistent; prefer CSS variables.

MV3 Migration Checklist (Future)

• Update manifest_version to 3
• Replace deprecated permissions or patterns
• Ensure no background page usage (currently none)
• Verify tabs permission behavior
• Re-test content script injection timing (consider document_idle vs document_end)

Known Limitations

• Snippet matching may fail if ChatGPT drastically changes DOM or content transforms (fallback: index search)
• Bookmark index can drift if messages are deleted or system messages appear mid-thread
• No sync across devices yet (local only)
