Originality.AI - AI Detector is a complete writing companion built for students, researchers, and professionals who need their work checked, polished, and properly cited before it goes out the door. Instead of juggling separate apps for originality checks, grammar fixes, and citations, Scriber brings everything into one place, so you can take a paper or an article from first draft to final version without switching tools. AI Detector reviews writing patterns to estimate how much of a text was likely generated by AI. Teachers, editors, and publishers can use it to review submissions, while writers can check their own drafts before handing them in. Plagiarism Checker scans your text against a wide range of online sources and academic material, flagging matching or closely paraphrased content so you can see exactly where your writing needs a citation or a rewrite. It's built to catch the details that matter for coursework, publications, and professional reports alike. Grammar Checker reviews your sentences for spelling mistakes, punctuation errors, and grammar issues as you write, offering corrections that keep your original meaning intact instead of just flagging a problem and leaving you to guess the fix. Proofreader goes a step further, looking at tone, clarity, and sentence flow so your writing reads smoothly from start to finish. It works just as well for a quick email as it does for a full academic paper. Humanizer rewrites AI-generated or stiff, robotic-sounding text into natural, conversational language, keeping the original meaning while making the result read like it was written by a person. Summarizer condenses long articles, reports, or research papers into short, clear summaries, making it easier to review key points quickly or put together a brief overview for someone else.
