Testimonials
I just wanted to say thank you for such a great and free service, all the other grammar checkers and writing assistants I have tried don’t have nearly the depth of features let alone all available on a free subscription. As a student with little income available I am extremely grateful that unlike all others companies you don’t limit features on the free plan. This is a fantastic product and given the income I would definitely upgrade to the premium. I've let all my fellow students know about Trinka as it is seriously a life saver.
First, I love Trinka. Congratulations on developing something that extensively aids editing, especially critical grammar conventions and word count reductions.
Writing texts with correct English grammar and style is not an easy task for people who speak other languages. Sometimes you cannot find little mistakes in your document without help and moreover for academic writing. I tried Trinka AI as a tool of automatic correction and was quite glad with the suggested corrections and the feedback. With the feedback you understand why the suggested change must be taken into account.
I have mainly used it to improve the language, grammar, and syntax of the scientific manuscripts that I write for national and international biomedical journals. I have found the interface to be user friendly and the procedure itself is efficient and hassle-free. The auto-edit is a great help and the supplementary page with the revision summary is an excellent idea.
Trinka.ai is my most favorite choice for grammar and spelling edit. The application works correctly, is fast and tidily! Completely satisfied!
The grammar checking tool exceeds Grammarly! I re-checked some documents that I had checked earlier with Grammarly. I was pleasantly surprised to see such a product from India!
Trinka has awesome features. Advance level of academic writing checker and suggestion are so original. I would highly recommend to others.
I have tested Trinka and am impressed with its fine capabilities. It did better than the grammar checker I use. Well done! I have told my colleagues in my research lab to use Trinka. Hope it is widely used in academia.
Trinka AI's suggested corrections and feedback astounded me. It is simple to use and extremely beneficial
It's been a wonderful experience using Trinka and I almost can't submit any manuscript without re-evaluating with it. In summary, Trinka has been a life-saver.
I enjoy using Trinka as a final spot check for my edited documents. It really helps find the few remaining errors that slip through during primary editing. I really like this platform. The thumbs down button is very useful.
I think Trinka.ai is a very interesting and potentially useful idea, especially for editors/publishers/journals. I found it very useful when I checked my editing work on the platform.
I am happy with the overall performance. I have been using Grammarly for a long while, but when it comes to academic or technical writing, Trinka is definitely a much better option. Academic document settings and auto file edit are my favorite features.
Trinka has become my go-to tool for grammar corrections. The AI-powered corrections and language enhancements made writing a lot more easier. Now I am able to focus more on research than on writing an error-free document.
The grammar correction and suggestion based on the AMA style guide is really impressive! Trinka is indeed the best grammar correction tool for medical writing.
