Free AI Detector — check images, video, text & audio for AI generation.
checkreal.ai is a free AI detector and AI content checker that covers every media type that matters: images, video, text, voice, music, and screenshots. Paste a link, upload a file, or paste text — the unified Truth Score engine returns a confidence number from 0 to 100 plus the specific signals that drove it. No signup, no rate limit, no upload to a backend server.
What is an AI detector?
An AI detector is a tool that estimates whether a piece of digital content was generated by an AI model rather than produced by a person. The detection problem now spans every category of media. An AI image detector looks at texture continuity and lighting coherence in photos. An AI text detector looks at sentence-rhythm regularity and generic-transition density in writing. A deepfake detector looks at facial-landmark stability and lip-sync alignment in video. An AI voice detector looks at prosody markers and voiceprint stability in speech.
Most AI detectors handle one of these categories. checkreal.ai is a free AI detector that covers all of them in one place, with a consistent Truth Score format across every check and an honest signal-by-signal breakdown that explains which patterns drove the score.
Writing tools — AI humanizer and humanization detector
The flip side of AI detection — rewrite AI text into natural prose, or catch text that’s been processed by a humanizer.
How the AI detector works
Every checkreal.ai AI detector routes inputs into one shared scoring engine. The engine reads the content type, runs the appropriate signal model, and returns a Truth Score from 0 to 100 plus a classification — Likely authentic, Inconclusive, Likely synthetic, or Likely manipulated. You see not just the number but the specific signals that drove it. For the full per-content-type signal models, see the methodology page.
- 1
Submit evidence
Upload a file, paste a link, or add text from a social post, email, receipt, or media clip. The AI detector accepts every common format.
- 2
Run one engine
Every AI detector page routes into the same scoring engine, so image, video, text, audio, and screenshot checks return a consistent result format.
- 3
Review signals
Each report explains the Truth Score, classification, and the specific signals — texture, compression, alignment, writing-pattern — that shaped the decision.
When to use the AI detector
AI detection is a triage tool, not a verdict. Use the AI detector when you have a clear question and want a structured second opinion before acting. The common situations:
- A viral image looks too clean. Run it through the AI image detector to check for generation markers before sharing.
- A short video may be a deepfake. Use the deepfake detector for face-coherence and lip-sync signals.
- A student essay reads off. Use the AI detector for teachers for a structured starting point — and follow up with a conversation.
- A profile photo looks generated. Run AI image detection on LinkedIn or dating-app avatars before trusting them.
- A payment proof looks edited. Use the fake screenshot detector before releasing goods on a marketplace.
- A voice call demands urgent money. Hang up first, call back to a known number, then run the recording through the AI voice detector.
For each of these, run the matching AI detector first, then combine the score with everything else you know about the source — who shared it, when, and whether the claim matches other reporting. The combination is the evidence; the AI detector score alone is not.

AI detector accuracy and limits
Every AI detector has accuracy limits. Independent benchmarks consistently show real-world performance below the numbers vendors quote in marketing — sometimes by a wide margin. The reasons are structural: platform compression strips signal, adversarial humanization defeats some detectors, and many human writers and photographers legitimately share patterns that look AI-typical.
checkreal.ai is upfront about this. The Truth Score is calibrated as a probability, not a verdict, and every result includes a signal breakdown so you can judge which patterns drove the output.

AI detector — common questions
What is an AI detector?
An AI detector is a tool that estimates whether a piece of digital content was generated by an AI model rather than created by a person. checkreal.ai is a free AI detector that covers every major media type — images, video, text, voice, music, and screenshots — with one consistent Truth Score format.
Is the AI detector free?
Yes — every detector on checkreal.ai is free, with no signup, no rate limit in the demo, and no upload to a backend. Files are processed in your browser.
How accurate is the AI detector?
Every AI detector has limits. We're upfront about ours. The Truth Score is a probability, not a verdict. Independent benchmarks consistently show real-world AI detection accuracy below the numbers vendors quote in marketing. See the methodology page for the detail.
Why use one AI detector across content types?
A shared scoring format makes every detector easier to compare, whether the input is an image, video, email, voice clip, or screenshot. The signal model under the hood differs by content type, but the result format stays consistent.
Can the AI detector be used for grading or hiring decisions?
No. No AI detector should be the sole basis for a high-stakes decision — academic integrity, employment, defamation, or legal action. Use the score as a triage signal that prompts a conversation, then combine it with provenance, drafting history, and source verification.
What kinds of AI content does the detector catch?
AI-generated images from Midjourney, Stable Diffusion, and DALL·E; deepfake video and face-swap clips; AI text from ChatGPT, Claude, Gemini, and other LLMs; cloned voices in audio; AI-generated music; and fabricated screenshots. Each gets a dedicated signal model.
Do you store the files I upload to the AI detector?
No. Detection runs in your browser. Files, links, and pasted text never leave your device. See the privacy page for the full data-handling description.
