Level 1 — Technical analysis
Facts read directly from the file: format, codecs, resolution, duration, bitrate, EXIF and XMP metadata, color profile, encoding and text statistics.

Analyze AI‑Generated Content
Analyze text, images, audio and video using multiple layers of technical, algorithmic and AI-powered analysis.
- Multi-layer facts, indicators, provenance
- No storage files deleted after analysis
- On-device audio & video stay in your browser
- Explained every signal shown with its value
Methodology
Three layers of analysis
Each layer is independent and clearly separated in your report, so you always know what is a fact, what is an indicator and what is an estimate.
Free
Level 2 — Algorithmic analysis
Statistical and signal-processing measurements computed without any AI model: sentence rhythm, lexical diversity, error level analysis, spectrum bandwidth, frame changes.
Coming soon
Level 3 — AI-powered analysis
Specialized detection models from named providers, with credits. Each provider and its data policy will be shown before any content is sent.
What we check
Built for every kind of content
Text
- Sentence length variation
- Vocabulary diversity (MATTR)
- Repeated phrases and openings
- Assistant-style phrases
- Hidden Unicode characters
Images

Transparent reports
Facts, indicators and a cautious conclusion
We never turn an estimate into a certainty. Every report separates what was observed from what was inferred, and explains why.
Read the methodology- FactsInformation actually present in the file.
- IndicatorsMeasured signals, each rated none, weak, moderate or strong.
- AI estimationProbabilistic model output, when Level 3 is available.
- ConclusionA cautious interpretation with its limitations.

FAQ
Frequently asked questions
What can TheiBusiness analyze?
TheiBusiness AI Analyzer examines four kinds of content: text (pasted or from a public web page), images, audio and video.
For each one, it reports the technical facts it can observe in the file (Level 1) and a set of algorithmic indicators computed from the content itself (Level 2). AI-powered analysis through specialized providers (Level 3) is coming soon.
Current limits
| Text | up to 50 000 characters |
|---|---|
| Images | JPG, JPEG, PNG, WEBP, GIF — up to 20 MB |
| Audio | MP3, WAV, M4A, AAC, FLAC, OGG, OPUS — up to 200 MB |
| Video | MP4, MOV, M4V, WEBM — up to 200 MB |
Can the analyzer prove that content was made by AI?
No. No detector, including ours, can prove that content was created by a human or by AI. The analyzer reports indicators: observations that are more or less common in generated content.
Results use cautious wording such as No significant indicators detected, Some unusual indicators detected, Multiple indicators detected or Analysis inconclusive. We never display “100% AI”.
The only exception is provenance metadata: when a file declares itself as AI-generated (for example through C2PA Content Credentials or IPTC metadata), the report says so, and notes that the declaration was not cryptographically verified.
Never use a result on its own to accuse someone of using AI.
Are my files stored?
- Text and images are sent over HTTPS to our server, analyzed in memory and deleted as soon as the analysis finishes. We do not keep a copy.
- Audio and video are analyzed directly in your browser. The file never leaves your device.
- URLs: the page or image is downloaded to a temporary file, analyzed and deleted immediately. Any leftover temporary file is removed automatically.
Nothing is sent to a third-party AI service. If AI-powered providers are added in the future, each one will be clearly identified before you send content to it.
Which file formats and sizes are supported?
These limits are read live from our configuration:
| Text | up to 50 000 characters |
|---|---|
| Images | JPG, JPEG, PNG, WEBP, GIF — up to 20 MB |
| Audio | MP3, WAV, M4A, AAC, FLAC, OGG, OPUS — up to 200 MB |
| Video | MP4, MOV, M4V, WEBM — up to 200 MB |
Audio and video decoding happens in your browser, so a format your browser cannot decode (for example some MOV codecs in Firefox) may only receive Level 1 container analysis.
