Hybrid AI search from your knowledge base and the internet
Combines live internet search with a personal knowledge base so answers draw on both public sources and your own documents.
Search, compare and summarize multiple images, and generate pages that pull in visual results alongside text.
Upload documents to build a knowledge base you can query directly for grounded answers to your own material.
Read, explain and even write code, making it useful for quickly understanding unfamiliar snippets.
AI content detection and a full writing toolkit in one place
Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
