Most popular ChatGPT extensions were built when "AI" meant one website. Today a lot of us switch between ChatGPT, Claude and Gemini several times a day — and that is exactly where single-site extensions start to feel narrow.
Below is an honest look at the best-known extensions, what each one is genuinely good at, and what to use if your work is spread across more than one AI. User counts and ratings are from each extension's Chrome Web Store page as of October 2026.
The quick comparison
| Extension | Best at | Works on | Users | Rating |
|---|---|---|---|---|
| AIPRM for ChatGPT | 4,500+ ready-made prompt templates (marketing, SEO, sales) | ChatGPT (separate extension for Claude) | 1,000,000 | 4.4 |
| Superpower for ChatGPT | Organizing ChatGPT: folders, search, bulk export, prompts, gallery | ChatGPT | 100,000 | 4.6 |
| ChatGPT Exporter | Polished ChatGPT exports: PDF, Markdown, text, CSV, JSON | ChatGPT | 200,000 | 4.9 |
| AI Toolbox | Folders, full-text search, prompts with variables, bulk export | ChatGPT, Claude, Gemini, Grok (full feature set on ChatGPT, per its listing) | 40,000 | 4.8 |
| AI Prompt Genius | Free, open-source prompt library with variables | Several AI sites | 100,000 | 2.8 |
| Qarta | Prompts with "/", plus an automatic, searchable library of every chat, with export | ChatGPT, Claude, Gemini, Copilot, Perplexity, Grok | New | No ratings yet |
When each one is the right choice
Pick AIPRM if you want someone else's prompts. Its strength is a huge catalogue of ready-made templates for marketing, SEO and sales tasks. If you mostly need your own prompts, it's more than you need.
Pick Superpower for ChatGPT if you live in ChatGPT. It adds a deep set of ChatGPT-specific tools — folders, search, galleries, a conversation tree map and more. It is built around ChatGPT, so it isn't designed for your Claude or Gemini chats.
Pick ChatGPT Exporter if the job is "turn this ChatGPT conversation into a nice file". It does that one thing very well, with many formats and PDF settings.
Pick AI Toolbox if you want a ChatGPT power-organizer that also reaches Claude, Gemini and Grok. Its listing says the complete feature set is on ChatGPT, with the other three covered partly.
Pick AI Prompt Genius if free and open source matters most and you only need a prompt list. Its current store rating (2.8) suggests checking recent reviews first.
If you use several AIs: what you actually need
When your work is spread across assistants, two problems show up every day:
- You retype the same instructions in each one — "summarize as bullet points", "rewrite politely for a client", "make this a table".
- You can't find an old answer, because you don't remember which AI you asked.
That's the gap I built Qarta to fill (full disclosure: I'm its solo developer, and it launched recently, so it has no ratings yet).
-
One prompt library for six AIs. Save a prompt once, then type
/and a keyword in the chat box of ChatGPT, Claude, Gemini, Copilot (personal), Perplexity or Grok. - Every chat saved automatically, in your own browser. Conversations you open are kept in a library on your computer (not synced, not uploaded), and titles and messages are searched together across all six AIs.
- Export when you need a document. A whole chat as Markdown or text is free; PDF, Word, HTML and tables to Excel/CSV come with Pro.
- Send one question to several AIs and read the answers side by side (Pro).
Pricing: free for 10 prompts and the last 30 days of chat history (every chat is still saved). Pro is $10/month or $96/year for unlimited prompts, your whole history, and the document exports.
Bottom line
- One AI and you want the deepest feature set for it → a single-site tool like Superpower for ChatGPT or ChatGPT Exporter.
- You want a big catalogue of ready-made prompts → AIPRM.
- You use several AIs and want your own prompts and your whole chat history in one place → try Qarta.
