Welcome to A*Help comments!
We’re all about debate and discussion at A*Help.
We value the diverse opinions of users, so you may find points of view that you don’t agree with. And that’s cool. However, there are certain things we’re not OK with: attempts to manipulate our data in any way, for example, or the posting of discriminative, offensive, hateful, or disparaging material.
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.
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.
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
I can see this being really useful for teachers too, not just students. The large number of free checks is pretty generous.
I’m a fan of the cross language search feature. Being a non-native English speaker, this feature is invaluable.
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.
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.
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. 😬
yeah that’s a major flaw. They need to up their game in that aspect.
OMG, the academic proofreading module is a lifesaver for checking citations. Finally, something for us folks drowning in research papers!
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!
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
Same here! A desktop version would’ve been cherry on top. But hey, the website is easy to use, so that’s something.
No browser extension? That’s a little backward if you ask me. What if I want to check content directly from the web? 🤔
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.
