Features & Capabilities

PromptVigil helps you use AI tools more safely.

It protects supported AI sites like ChatGPT, Claude, and Copilot by scanning prompts, responses, links, and supported file uploads before risky content causes harm.

What PromptVigil does:

Warns before sensitive data is shared with AI tools
Detects exposed secrets such as API keys and tokens
Flags suspicious links and scam-style content
Detects common prompt injection and unsafe instruction patterns
Redacts risky content when a safer retry is possible
Shows an activity log with redacted event details and action history
Provides local-first protection controls and policy settings

How it works:

PromptVigil analyzes supported AI interactions locally in the browser by default
Raw prompts and raw AI responses are not sent by default
Raw text logging is off by default
Anonymous telemetry is optional and does not include raw prompt or response text

Who it is for:

Individuals who want safer daily AI use
Teams that want guardrails for AI prompts and file uploads
Organizations that want visible, user-facing AI interaction protection

Current protection areas:

Sensitive data and payment-like values
Secrets and credentials
Suspicious links
Prompt injection patterns
Fraud and scam-style content

PromptVigil is designed to reduce accidental oversharing and risky AI interactions without requiring users to change how they work.

Is PromptVigil 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.

PromptVigil requires a lot of sensitive permissions. Exercise caution before installing.

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.

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