Analyze, Score & Refine Prompts Inside Your AI Tools
The PromptPal Chrome Extension is your AI assistant for the web — score prompts in real time, improve them with one click, and inject the result back into ChatGPT, Claude, Gemini, and 20+ supported sites.
Score updates as you type
What the Extension Does
Built for the way you already work — inside the chat box, not in another tab.
Real-time prompt scoring
See a live quality score as you type in the Improve tab — know when a prompt needs work before you send it.
Improve with style controls
Refine prompts with Default, Concise, Detailed, Technical, or Creative styles — tuned to how you want the model to respond.
Use in page
Inject your improved prompt directly into ChatGPT, Claude, Gemini, and other supported inputs — no copy-paste.
Side panel workspace
Open the Chrome side panel for a full workspace: Improve, Templates, Library, and settings without leaving your AI tool.
Refine Agent
Answer a short guided flow in the side panel and PromptPal builds a sharper prompt tailored to your context.
Templates & library sync
Browse saved templates and your PromptPal library in the extension. Changes sync with your account when signed in.
Two Ways to Work
Use the compact popup for quick wins, or the side panel for Refine Agent and a larger workspace.
Extension popup
Quick access from the toolbar: score, improve, apply to the page, and jump to Templates or Library.
Chrome side panel
Full workspace with Refine Agent, larger editor, and the same library — open it from the popup in one click.
- Floating weak-prompt indicator on supported sites
- Per-site enable/disable in extension Settings
- Optional auto-open side panel when a weak prompt is detected
Works on 20+ Sites
PromptPal runs on the AI and productivity surfaces you already use. Enable or disable each site in extension Settings.
Connected to Your PromptPal Account
Sign in from the extension or connect from the web app. Your templates and library stay aligned when you are online — so improvements you make in the browser show up in PromptPal and vice versa.
Sign in once
Use Google sign-in in the extension, or connect from promptpal.app — your session stays in sync across surfaces.
Full library in your browser
Access templates and library prompts from the extension popup or side panel without opening a new tab.
Instant two-way sync
Save a template or pull from your library on the web — updates appear in the extension when you are signed in.
Cached for speed
Recently loaded library and template lists are cached locally for faster access. Analyze and improve still use PromptPal online.
