Questions
AuthentiqAI is built for anyone who needs clarity about the authenticity of digital content - educators, researchers, freelancers, creators, students, and professionals who want to verify, refine, or review the work they’re handling.
You can verify whether text, images, or videos may be AI-generated, check for plagiarism and originality, or refine your writing using the Natural Writing Assistant.
Yes, all AI detectors can produce occasional false positives. AuthentiqAI is designed to minimize this risk as much as possible and clearly show why something may have been flagged, so you can interpret the results fairly.
Look at the highlighted sections and confidence indicators to understand what patterns were detected. If you still believe it’s a false positive, you can submit it for review. These reports help us improve our models and reduce uncertainty for future users.
Your flagged result is not a verdict - it’s a signal. You can support your originality by sharing drafts, notes, outlines, version history, or other documentation of your writing process. Educators can use the flagged sections as a starting point for a conversation, not an accusation. Meanwhile, freelancers respond by using our results as a more accurate and transparent analysis.
Our system uses multi-model analysis across major LLMs (including GPT, Claude, and Bard) along with forensic checks for images and video. No detector is 100% accurate, but our goal is to give you the clearest, most evidence-based signal possible.
No. The assistant focuses on subtle, human-aligned improvements - not full rewrites. It helps you refine your writing without introducing patterns that detectors typically flag.
No. Your data is never stored, saved, or used to train our models. Everything you upload is processed securely and then deleted.
You can paste text directly or upload PDF, DOCX, or TXT files. Image and video verification accepts formats like JPG, PNG, and MP4.
AuthentiqAI analyzes text across several major large language models, including GPT, Claude, and Bard. We continually update our system as new models emerge.
