#AI detection
9 tools curated for you
Verify the authenticity of any image instantly by uploading JPG, PNG, or WEBP files for a deep analysis of visual patterns and textures left by AI generators. Identify which specific AI model created an image, such as Midjourney, DALL-E, or Flux, with a per-generator confidence score that reveals the exact source. Catch AI-manipulated content even after metadata or watermarks are stripped, because the tool examines structural artifacts that persist in online images. Prevent fraud in KYC checks and document verification by detecting AI-generated or partially edited elements in identification photos and scanned images. Protect your credibility as a journalist or publisher by confirming images are original before publication, stopping the spread of deepfakes and synthetic media. Maintain trust in online marketplaces by verifying that artworks and product photos are not AI-generated, preserving authenticity for buyers and sellers. Detect partial AI edits or regenerations in photos, not just fully synthetic images, for thorough digital forensics and content moderation.
Verify whether an image is AI-generated or human-made in seconds with a probability score and confidence label, powered by statistical signal analysis. Protect against dating app scams and e-commerce fraud by checking profile photos and product images for synthetic origins before engaging. Prevent identity fraud by detecting AI-generated faces used in fake personas across social media, rentals, and professional networks. Combat fake news and art theft by confirming the authenticity of images in news circulation or affirming human creation of artwork. Integrate image authenticity detection into existing workflows at scale using the developer-friendly API, enabling automated checks for large volumes. Preserve complete privacy during every check—submitted images are processed instantly and never stored, with no detection history retained. Analyze images from popular AI generators across multiple formats (JPG, PNG, WebP) with a simple upload or URL paste, delivering results within seconds.
Make confident decisions about image authenticity by seeing each detection model's vote side-by-side, enabled by four independent AI-detection models with a published weighted-vote rule. Trust your results even when models disagree, because the tool reports conflicts instead of hiding them, delivering transparent evidence from every engine. Screen large volumes of images in minutes by analyzing up to 50 images at once, powered by parallel multi-signal forensic screening. Eliminate guesswork from AI image detection with graded conclusions ranging from AI-generated to real, providing nuanced authenticity verification instead of a binary answer. Override all detection models with certainty when file evidence exists, thanks to C2PA credential and generator self-tag verification that takes precedence. Streamline bulk image review with triage summaries and CSV exports, turning simultaneous analysis of 50 images into organized, sortable reports. Get started without upfront cost by running a full report using all signals with 3 welcome credits, offering free AI image detection for initial verification.
Identify which exact sentences in a document read as AI-generated using sentence-level signal analysis, so you can target edits where they matter most instead of rewriting entire drafts. Judge how much of a text was machine-written with a probability-based AI score and confidence indicators, giving you a realistic signal rather than a false yes-or-no verdict. Evaluate content written by any major model—ChatGPT, GPT-4o, GPT-5, Gemini, Claude, DeepSeek, Llama, Grok, Copilot, or Mistral—using model-agnostic detection built to catch shared AI writing patterns. Screen full articles, reports, emails, and marketing copy in one pass by analyzing English text from 80 up to 10,000 words per check. Get detection results within seconds of pasting or uploading text, so you can clear a submission, draft, or client deliverable without workflow delays. Run unlimited AI detection checks at zero cost with no ads, no paywall, and no account required, making it practical for high-volume content review. Track how a document's AI probability changes across revisions by creating a free account and using Check History to revisit and compare past analyses. Spot the statistical fingerprints of AI writing—predictable wording, flat sentence rhythm, recurring phrases, and repeating patterns—to assess content authenticity before publishing. Support editorial and SEO decisions across writers, editors, publishers, and content teams by flagging potential AI-generated patterns in articles, product descriptions, and web copy.
Choose the right AI detector for your needs by seeing how GPTZero, Originality.ai, Winston AI, Pangram, Sapling, and ZeroGPT perform against each other on the same text, using head-to-head comparisons that reveal relative strengths and weaknesses in AI text detection. Get unbiased accuracy insights through blind pairwise voting where detector identities are hidden during evaluation, eliminating brand bias and delivering fair, performance-based results you can trust for informed decision-making. See live rankings of AI detection tools powered by Elo-based scoring that updates as tools compete, giving you a transparent, data-driven view of which detectors consistently deliver the best text detection performance. Contribute any text for benchmarking and watch multiple AI detectors analyze it simultaneously, building a crowdsourced database that improves comparative analysis of detection efficiency and accuracy for developers, researchers, and entrepreneurs. Evaluate detector capabilities side by side without testing each tool individually, saving time and effort while gaining comprehensive insights into functionality, accuracy, and suitability for your specific AI detection requirements.
