About Serenity Tools for ChatGPT
ChatGPT is great until your best replies disappear in old chats and your favourite custom instructions are scattered everywhere in random documents.
Serenity Tools for ChatGPT helps you keep things organized. Bookmark useful responses, save reusable instruction sets, and switch between them in one click.
It’s designed to make ChatGPT easier to use when you’re moving between different tasks, projects, or workflows, perfect for power users.
Features
1. Bookmark useful ChatGPT responses
Save replies you want to come back to later with a bookmark button to the top right of each post. Bookmarked replies are highlighted in blue for easy tracking in long chats, and can be un-bookmarked by clicking the bookmark button again, or from deleting the bookmark in the bookmarks popup menu.
2. Create and save custom instruction sets
Store multiple custom setups for different use cases (writing, research, coding, brainstorming, and more).
3. Apply saved sets in one click
Switch context quickly without copy pasting instructions from another document. Clicking apply on a set of custom instructions opens the personalisation menu, fills out the custom instruction fields accordingly, saves the new instructions and closes the window, letting you pick up from where you left off!
4. Organize with tags and pinning
Add a tag, filter by tag, and pin the items you use most.
5. Search saved items
Quickly find bookmarks and instruction sets by title or tag.
6. Quick import for instruction sets
Paste a formatted template once to fill all fields automatically (title, tag, "Custom Instructions", and “More about you”). This is necessary since chrome extension popups always disappear if you click away from them, meaning all fields need to be filled in at the same time.
