Features & Capabilities

PromptMate is a privacy-first productivity extension for anyone who uses AI chat tools like ChatGPT, Claude, Gemini, or any other AI interface.

🔒 PII Masker Automatically masks emails, phone numbers, and any custom terms you define before you paste text into an AI chat. Your sensitive data never leaves your browser — masking happens entirely on-device.

✨ Prompt Enhancer Right-click any AI chat input field and select "Enhance prompt with PromptMate" to instantly rewrite your draft into a clearer, more effective prompt using Google's Gemini API. You use your own API key — your text goes directly from your browser to Google, never through our servers.

📚 Prompt Library Save and manage reusable prompts. Insert them in one click from the popup — perfect for recurring tasks, templates, or workflows.

⚙️ Allowed Sites Control exactly which domains PII masking is active on. You decide where the extension runs.

🛡️ Privacy by design No accounts. No analytics. No telemetry. Everything is stored locally in your browser. Uninstalling the extension deletes all your data.

How to get started:

Click the PromptMate icon to open the popup
Add your custom PII terms in Settings
Optionally add a free Gemini API key from aistudio.google.com to enable prompt enhancement
Start pasting — your data stays yours

Is PromptMate Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PromptMate requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

PromptMate is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
