Get started with IA Checker
IA Checker combines focused tools for detecting AI signals and improving text. Start with the content you have, then follow the evidence from the headline result into the detailed signals.
Choose a workflow
| What you have | Start here | What you receive |
|---|---|---|
| Pasted text | AI Text Detector | Sentence-level signals and an AI probability |
| Public web page | URL analysis | Readable page text and a detection report |
| PDF, DOCX or scan | Document Reader | Extracted text ready for a check |
| JPG, PNG or WebP | AI Image Detector | Visual, forensic and provenance signals |
| Text to improve | Writing tools | A rewrite, correction, translation or summary |
Read every result in three parts
- Verdict
The clearest summary of how the measured signals lean.
- Probability
A normalized reading for the analyzed content, not a claim about who authored it.
- Evidence
The sentence, visual, file and provenance checks that shaped the result.
Use the evidence to understand why the result moved. Longer text, original files and preserved source data generally give the analysis more to work with.
