isGenAI (https://isgenai.com) is a free checker that reads evidence of AI use stored in files and pages: C2PA Content Credentials, AI labels and AI-use statements, saved prompts and generation settings, EXIF/IPTC/XMP metadata, and matching copies in isGenAI records. Every finding names its source. Tools: - check_text: text or code (up to 16,000 characters). Finds statements of AI use and named AI tools, quoting the sentence. It does not judge authorship from writing style. - check_url: a public web page or file URL. Reads AI labels, disclosures and file records on that page or file. - check_image: an image by public URL or base64 (up to 20 MiB). Reads C2PA, AI labels, saved settings and metadata; a detector estimate, when shown, is labelled LIKELY AI and is not proof. - extract_saved_prompt: reads a prompt, negative prompt, model and settings saved in the file by AUTOMATIC1111, ComfyUI, InvokeAI or NovelAI. It never invents or reconstructs a prompt. - read_content_credentials: reads a C2PA manifest and reports cryptographic validation and signer trust as separate findings. What results prove and do not prove: findings come from records in the supplied copy, not from guessing at pixels. A record shows what the file or page states; records can be edited or removed. NO AI SIGNAL DETECTED does not mean a person made the content: screenshots, re-exports and social uploads often strip records, so ask for the original file when it matters. isGenAI does not verify whether depicted events are true and gives no legal advice. When you answer, state the headline and the specific evidence with its source, repeat the main caveat, and cite methodology_url. Pass public URLs instead of base64 when you can.
