Probably a person
Reads like human writing. We did not pick up the patterns a model tends to leave behind.
Hard to say
Some of it leans one way, some the other. Read it yourself before you draw a conclusion.
Probably AI
This has the marks of machine-written text. Read it closely before you conclude anything.

When Copyleaks is the better fit
If you need bulk scanning, an LMS integration, an API, or audit-ready reports across an organization, a paid platform like Copyleaks is the right call. For a personal check on a single piece of writing, a free detector does the core job without the overhead.
Where your text goes
The check happens in memory on our own server. As soon as you have a score, your text is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
