Why it goes unnoticed
Tools catch copies. Not authors.
Word-for-word copies are rare: texts get rewritten, headlines changed, sentences reordered. But an author's habits — favourite words, turns of phrase, punctuation — are hard to hide. That is exactly what CopyTrace compares.

Three channels are most likely run by one person or share one template. Treat them as one source, not three.

Why trust it
A conclusion you can verify
You see the evidence
No black box: we show the words and fragments that match, so you can check the conclusion yourself.
Science, not magic
Stylometry has decades of research behind it. Accuracy grows with text length, so short posts are combined per channel.
Your texts stay yours
Texts are used only for the check and are not kept afterwards: only the results and short matching fragments remain, and they go when you delete the check. Teams can run it on their own server.

Questions and answers
Frequently asked questions
01Does it work with short Telegram posts?
Yes. Combine a channel's posts into one text and CopyTrace compares channels as a whole. The more text, the more reliable the result — ideally 500+ words per source.
02I can spot identical texts myself. Why do I need CopyTrace?
Exact copies are rare — texts get rewritten. CopyTrace notices a shared writing style even when no sentence matches word for word. Dozens of sources in a minute.
03What if my honest channel looks similar to others?
Similarity can have a simple cause: a shared topic, a house style or the same press release. CopyTrace shows exactly what matches, so you see the reason and draw the conclusion yourself.
04Do I need special skills?
No. Add your sources and click “Check” — the result is clear without training.
05Do I have to pay now?
No. Joining early access is free. Paid plans start after launch, and the free plan stays available to everyone.
