XXL Prompt Manager exists because most people who use AI daily retype the same instructions over and over, or dig through notes to find a prompt they know they wrote somewhere. The extension puts a prompt library in a sidebar on the AI chat sites you already have open, so a saved template is never more than a hotkey away. Press Alt+P or click the sidebar tab to open your collection without leaving the conversation.
The free tier covers the essentials and imposes no cap on the number of prompts you can store. You can group prompts into folders, search for them instantly, and turn parts of a prompt into smart [variable] placeholders — so a single template like "write a [tone] email about [topic]" becomes reusable for every client or project instead of being rewritten each time. One click drops the finished text into the chat box, so the copy-paste step disappears. Because the same sidebar travels between supported sites, the library you build while using ChatGPT is already there when you switch to Claude, Gemini, Perplexity, Copilot, Kimi, Mistral Le Chat or DeepSeek.
Pro adds the parts that matter once prompt management becomes real infrastructure: up to 20 profiles (one per client, brand or project), cloud sync with automatic backup so the same library appears on every machine you sign in to, a web app for use on phone or any browser, plus 3,000+ ready-made templates and 12 premium themes. Storage stays local on the free plan and the extension states that it never reads the content of your AI conversations.
