Why Lynote is the Best AI Image Detector?

More than a single percentage — a clear, reviewable result.

• 99% Detection AccuracyHigh-confidence detection of AI-generated, edited and blended images.
• Detects Leading GeneratorsMidjourney, Stable Diffusion, DALL-E, FLUX, Firefly and many more — in one tool.
• Deep Artifact AnalysisChecks generator fingerprints, texture artifacts, and editing traces — not just metadata.
• Compression-AwareHandles screenshots, re-uploads and compressed copies that fool naive checks.
• Safe & ConfidentialImages are processed securely and never used for model training.
• Clear Probabilistic SignalAn AI-generated score you can interpret — a signal, not an absolute verdict.

How to Use the Free AI Image Detector

Three steps from image to result.

1. Step 1Upload an ImageUpload a JPG, PNG or WEBP file, or paste an image from your clipboard.
2. Step 2Click DetectLynote scans generator fingerprints, artifacts and editing traces.
3. Step 3Review the ResultSee the AI-generated score and decide how much weight to give it.

What Lynote Detects

Signals that machine-generated images leave behind.

• Generator FingerprintsPatterns specific to Midjourney, Stable Diffusion, DALL-E and FLUX outputs.
• Texture ArtifactsOver-smoothed regions, repeated micro-patterns and unnatural detail.
• Editing TracesInpainting and retouching marks on otherwise real photos.
• Metadata & ProvenanceWhere available, embedded generator metadata and history.

Flagged as AI? What to Do

• Check the SourceReview where the image came from — generator prompts, editing history and upload metadata matter.
• Compare With ContextReal photos often have camera EXIF, RAW history or recognizable scenes. Use context, not one score.
• Request the OriginalAsk for the full-resolution original before making decisions about an image.
• Combine Multiple ChecksUse more than one detector and a human reviewer for important decisions.

Who Uses This AI Image Detector

A practical review step for anyone working with visual content.

• Journalists & Fact-CheckersVerify photos before publication and flag synthetic imagery quickly.
• Content ModeratorsScreen user-uploaded images at scale for AI-generated content.
• E-Commerce TeamsCheck product photos and seller submissions for synthetic images.
• HR & RecruitersSpot AI-generated profile photos and submitted visual materials.
• ResearchersAudit visual datasets and social media corpora for synthetic content.
• Designers & CreatorsVerify the provenance of assets before licensing or publishing.

Frequently Asked Questions

Is this AI image detector free?

Yes. Lynote offers a free AI image detector — upload an image and get your first check without creating an account.

Are AI image detectors accurate?

Useful, but no detector is perfect. Compression, screenshots, retouching and new generators can all cause errors. Treat the score as a probabilistic signal, not proof.

Which generators can you detect?

Midjourney, Stable Diffusion, DALL-E, FLUX, Firefly and many other major generators. New generators may not resemble the model's training data.

Does it work on screenshots or compressed images?

Screenshots and heavy compression can change predictions. The detector is compression-aware, but for important decisions always test the original file.

Does Lynote save my images?

Images are processed securely and are not used to train models or shared with third parties.

This Space is a static landing page for Lynote's free AI image detector. The interactive demo requires Hugging Face PRO hosting; the full product — upload, detect and review — is available at lynote.ai/ai-image-detector. No AI detector is perfect: scores are probabilistic signals, not proof of provenance, and false positives are possible — especially with compressed, retouched or unusually processed images.
