The extensions in detail
XXL Prompt Manager
A sidebar with your own prompt library on 11 AI chat sites. You save prompts, sort them into folders, use [variables] for the parts that change, and copy the finished prompt with one click.
- Good for: people who use more than one AI and reuse the same prompts every day. The free version has no limits and needs no account; prompts stay in your browser.
- Also: a profile, background text (who you are, your audience, your tone) that is added to every prompt you copy, like custom instructions that work in all 11 chats. Pro keeps up to 20 profiles, for example, one per client.
- Keep in mind: it copies the prompt and you paste it (Ctrl+V); it doesn't type into the chat box for you. It doesn't rewrite prompts with AI. Syncing between computers needs Pro.
AIPRM for ChatGPT
The best-known prompt extension, with a large catalog of prompt templates written by its community, strongest for SEO and marketing tasks.
- Good for: browsing ready-made prompts inside ChatGPT.
- Keep in mind: built for ChatGPT (Claude has a separate extension). How many of your own private prompts you can save depends on the plan: 10 on Plus ($20/month), 40 on Pro ($39/month).
Superpower for ChatGPT
A large set of extra features for ChatGPT: folders for chats, a prompt library, prompt chains and more.
- Good for: heavy ChatGPT users who want many features in one extension.
- Keep in mind: ChatGPT only. The free tier stores 5 prompts.
AI Prompt Genius
A free, open-source prompt library, originally called "ChatGPT Prompt Genius".
- Good for: anyone who wants a free, open-source tool.
- Keep in mind: the rating (3.3★) is the lowest on this list; read the recent reviews first.
Promptly
A prompt improver with a side-panel prompt library and a public community library.
- Good for: improving prompts with AI and keeping a library, for free.
- Keep in mind: improving a prompt means sending it to an AI model; check its privacy policy if that matters to you.
PrettyPrompt
A "Grammarly for prompts": it rewrites and refines what you type.
- Good for: people who mainly want better prompts, not a library.
- Keep in mind: the free tier has 5 improvements per week and no saved library.
AI Toolbox
Organizes chats with folders and bookmarks, and includes a prompt library on four AI sites.
- Good for: keeping long chat histories tidy.
- Keep in mind: paid plans are sold per AI site; the free tier stores 2 prompts.
How to choose
- Do you want to store your own prompts, or get better ones? Storing and reusing: a prompt library (XXL Prompt Manager, AI Prompt Genius). Improving: a prompt enhancer (PrettyPrompt, Promptly).
- Which AIs do you use? If it's more than ChatGPT, check that every site you use is named in the listing.
- How many prompts will you keep? Free tiers range from 2 saved prompts to unlimited. Count what you already keep in notes.
- Where should your prompts live? Some tools keep them in the browser, others on their servers. The privacy section of each Chrome Web Store listing says what the extension collects.
When XXL Prompt Manager is not the right pick
- You want AI to rewrite or improve your prompts: XXL doesn't do that.
- You want your whole team to share one prompt library: there are no team features.
- You mainly want to organize chat history: XXL manages prompts, not conversations.
- You want the prompt typed straight into the chat box: XXL copies it, and you paste.
Frequently asked questions
What is a prompt manager?
A tool that saves the prompts you use often, keeps them organized (usually in folders) and puts them back into your AI chat quickly. Many support placeholders such as [topic] that you fill in each time.
Is there a free prompt manager without limits?
Yes. XXL Prompt Manager's free version has no cap on prompts or folders and needs no account. AI Prompt Genius is free and open source. Promptly is free too.
Which prompt manager works with Claude and Gemini?
XXL Prompt Manager, Promptly, PrettyPrompt and AI Toolbox name ChatGPT, Claude and Gemini in their listings. AIPRM and Superpower focus on ChatGPT.
Do prompt managers send my prompts to a server?
It depends on the tool. Anything that rewrites prompts with AI has to send the text to an AI model. Libraries can work entirely in the browser: XXL Prompt Manager's free version stores prompts only in your browser, and Pro sync (opt-in) stores them in the cloud so they are on every computer you sign in to.
