Decopy AI is a free writing workspace with no login required. It detects AI text, humanises it, summarises, transcribes and helps with homework, working across text, documents, images, audio and video.
Several of those are ordinary and useful. Transcription across audio and video, summarising a long document, and pulling text out of an image are unremarkable tasks that a free accountless tool is a perfectly good way to do, and not requiring a login is worth something in a category that gates everything behind an email address.
The problem is a sentence in its own FAQ. Alongside the humanizer, the site states that it **effectively bypasses Turnitin’s AI detection** — naming an academic integrity system as something the product defeats. That is a step past shipping a humanizer and hoping nobody asks what it is for: it is the use case, written down by the vendor. Set beside a homework assistant aimed at the same users, the intended workflow is not ambiguous. It also runs a detector next to the humanizer, the self-defeating pairing found three times already in this catalogue. Use the transcription and the summariser; what the rest is for is stated on the site.
