I tried the OCR scan with some of my handwritten notes, and it worked smoothly. This tool is going to save me so much time.

Emmanuel Escobar September 21, 2023

The lack of a spelling and grammar check is a downer for me. I mean, it’s a text-checking tool, right? Seems like a missed opportunity.

Mia Sosa September 29, 2023

Agreed! I was hoping to get all the text checking done in one place. Looks like I’ll need a separate tool for grammar and spelling. But i’m sure it’s gonna be added in one of the future updates

Madison Hendricks September 17, 2023

I can see this being really useful for teachers too, not just students. The large number of free checks is pretty generous.

Alexandre Marshall September 13, 2023

I’m a fan of the cross language search feature. Being a non-native English speaker, this feature is invaluable.

James Curry September 11, 2023

Okay, Copyleaks seems like the real deal for plagiarism checking. The fact that it can check AI paraphrase and the user experience score is quite high is promising.

Isabella Hanna September 7, 2023

I tried the free trial, and it was impressive. Although, I wish it included a grammar and spelling check feature too. That would’ve made it a comprehensive tool for students.

Elizabeth Wright September 2, 2023

But guys, did you see the replaced characters detection? A whopping 0%? That’s a huge blind spot, especially when people get creative with replacing characters to avoid plagiarism detection. 😬

Jazmine Russell September 2, 2023

yeah that’s a major flaw. They need to up their game in that aspect.

Allen Cardenas August 31, 2023

OMG, the academic proofreading module is a lifesaver for checking citations. Finally, something for us folks drowning in research papers!

Austin Walters August 24, 2023

I think the price point with the available discounts makes it a good value for money. I mean, cheap plans plus a good range of features? I’m sold!

Malachy Santiago August 14, 2023

Anyone else bummed about the lack of a desktop version? I’d love to have that kind of access without always having to go through the web

Taya Blevins August 15, 2023

Same here! A desktop version would’ve been cherry on top. But hey, the website is easy to use, so that’s something.

Lois Dean August 8, 2023

No browser extension? That’s a little backward if you ask me. What if I want to check content directly from the web? 🤔

Emil Davis August 11, 2023

Exactly my thoughts! A browser extension would’ve made it a go-to tool for sure. Still, 100% detection on Internet samples is no joke.
