Mobile AI detection for text, images, and audio
AI Detector App for iPhone and Android
Check the content you encounter on your phone, then review clear AI and human probability signals without moving files through a desktop workflow.
Built for mobile checks
Start with the file already on your phone.
Import a document
Bring in readable text from a PDF or use camera text recognition when the words are inside a photo.
Choose an image
Review a suspicious photo or illustration saved from a message, website, or social feed.
Select audio
Analyze a saved MP3, WAV, or M4A recording when a voice sounds synthetic or cloned.
Why use an AI detector app instead of a browser tab?
Mobile content rarely begins as a clean block of text. It arrives as a screenshot, a PDF in a class portal, a photo in a group chat, or a voice note. A mobile AI detector app reduces the extra steps between finding suspicious content and reviewing it because the file is already on the device.
That convenience does not make a score more conclusive. The useful mobile workflow is to preserve the original, analyze the strongest available sample, and keep the result beside the source context. If a decision affects a grade, payment, identity, or reputation, verify it with evidence outside the detector.
Prepare a better text sample before scanning
One sentence, a title, or a list of fragments gives a text detector little context. Use a complete paragraph or several connected paragraphs when possible. Stealth AI Detector requires at least 200 characters, and longer coherent samples generally produce a more useful signal.
Use the free AI text sample checker to confirm the character count and structure before opening the app. Students who are worried about a false flag can also prepare an essay authorship evidence checklist before contacting an instructor.
A simple phone workflow
From saved content to a readable signal.
- 01
Choose the content type
Open text, image, or audio detection based on what is already saved on your phone.
- 02
Use the best sample
Keep the original file when possible and avoid very short, heavily compressed, or incomplete samples.
- 03
Review the probabilities
Read AI and human signals as one part of a wider review, not as proof of authorship or identity.
Before you download
Mobile app questions.
Is there an AI detector app for both iPhone and Android?
Stealth AI Detector is available from the Apple App Store and Google Play, with text, image, and audio analysis in the mobile app.
Can I check a screenshot or PDF on my phone?
The app can use readable text imported from a PDF or captured with camera text recognition. For an image itself, select the image-detection workflow instead of treating the screenshot as text.
Does the app prove that content was made by AI?
No. Detection scores are probability signals and can be wrong. Preserve the source, drafts, provenance, and surrounding context before making a decision.
Is the AI detector app free?
The app is free to download. Analysis and writing features require an active in-app subscription; review current pricing in the App Store or Google Play.
