Prompt injection FAQ

Last reviewed: August 30, 2026 · Editor: Prompt Injection Check

What is prompt injection?

It is content that tries to redirect an AI from its intended task, reveal hidden information, or take an unauthorized action.

Is it the same as a jailbreak?

No. A jailbreak targets a model’s safety boundaries; prompt injection often targets a workflow that reads untrusted external content.

Does a clean scan mean content is safe?

No. The scanner recognizes reviewed textual patterns and can miss novel, multilingual, image-based, or context-dependent attacks.

Does scanning upload my text?

Prompt Injection Check processes the text in browser memory and does not send it to its server or an AI API. You should still avoid pasting secrets.

What should an AI agent do with suspicious content?

Treat it as data, preserve the original task, avoid tool calls, and escalate sensitive actions to a human.

Where can I learn more?

Start with what prompt injection is, then read the prevention checklist and run a redacted sample through the scanner.
