A few useful answers.
What is prompt injection?
It is an attempt to make an AI follow instructions in content it was meant to read or summarize. Those instructions can appear in a file, a web page, or image text.
Can a scan tell me a file is safe?
No. A scan shows potential issues in the content it could inspect. Read the evidence and coverage notes before deciding how to use the file.
What does the app cost?
The free download includes one scan per month. An optional monthly subscription provides unlimited scans and in-app automation. See current pricing in the app.
Can I keep the results?
Yes. Reopen saved scans in Recents and export a PDF or JSON report. Evidence snippets are redacted by default.
