What is Decopy AI?

Decopy AI product thumbnail

Decopy AI is a free, no login web platform for detecting AI generated text and images, humanizing AI text, summarizing video and audio, and running OCR. It identifies output from ChatGPT, Claude, and similar models, supports multiple languages, and bundles tools for transcription, text to speech, math help, and homework assistance into one site.

Why Decopy AI works

Teachers, marketers, and writers face a flood of AI text and images and have no easy way to tell what is real. Decopy AI runs detection and humanization in one place at no cost, which removes the friction of paying separately for an AI detector, a humanizer, and a summarizer.

Decopy AI features

  • AI text detector. Identifies text generated by ChatGPT, Claude, and similar models, including paraphrased AI content per the page.
  • Humanize AI text. Rewrites generated text so it reads more naturally and matches the tone of human written copy.
  • AI image detector. Detects AI generated images and runs reverse image search to find where images appeared online.
  • Multi format summarization. Summarizes YouTube videos, PDFs, documents, and audio into key points.
  • OCR and homework tools. Extracts text from images and includes math problem solver and homework helper modules.

Who Decopy AI is for

  • High school and college teachers checking whether student essays were drafted by ChatGPT.
  • Marketing managers reviewing freelance writers' deliverables for AI generated filler before publishing.
  • Academic researchers verifying that sourced quotes and images are authentic rather than synthetic.
  • Visual artists who want to check whether their work is being scraped or reposted by AI image services.
