accurate detection

Pros

It's been exceptionally accurate at spotting AI written text and the whole tool is very easy to use. The free limit of 10,000 characters is really helpful, it processes quickly and the file upload option makes it even more convenient. I've never even had to contact support because everything is clear and simple from the start.

Cons

One thing that gets annoying is that when I paste text in, it opens a separate browser tab to run the check.

reliable contract verification tool

Pros

We mainly rely on it to tell whether text was generated with GPT or actually written by the person especially when reviewing contracts that may have been created with ChatGPT instead of drafted by them. It speeds up our analysis a lot and also helps us confirm (along with the legal team) whether someone is submitting legitimate details or trying to pass off fake contracts.

Cons

I really don't have any major complaints because it works well overall. If I had to point out one thing it would be the pricing which seems a little on the expensive side.

clear highlights you can trust

Pros

It gives clear, transparent results and the sentence level highlights make it easy to see why something gets flagged instead of just showing that it was flagged. That makes it feel practical and reliable especially in academic and professional settings.

Cons

At times it seems a bit too cautious and may mark human written content as AI generated. That can be frustrating when the text is genuinely original. I also wish the free version included a slightly higher text limit for testing.
