## Testimonials

Trinka has allowed me to improve the articles I have published. In addition to giving me suggestions for journals according to my research.

Hugo Alberto Rivera Rodriguez

Assistant Professor, Universidad del Rosario, Colombia

Trinka has greatly streamlined the work on my research. As a non-native English speaker, I used the services of a language editor before finalizing the article, which took weeks and cost a large amount of money. With Trinka, I can spend much more time on the research itself.

Michal Plaček

Professor of Public and Social Policy at Charles University,
Prague, Czech Republic

I have been using Trinka for several years and have had a very positive impression. This tool really helps improve the quality of writing. I especially liked the grammar and style checker, which not only found errors but also provided recommendations on how to correct them. The program interface is intuitive, which is an advantage for new users. Trinka is a versatile tool for publishing professionals. I recommend it to anyone seeking to improve their writing skills.

I met Trinka while searching for a reliable companion to assure the correct publication of my university classes and books abput the spirituality of contemplation. With a Premium account I can revise the grammar and text flow of my manuscripts in Spanish, English and German Language.

Great stuff!

Abdi Yusuf

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.

Rosa Diaz Sandoval

Physics and Mathematics PhD, Mexico

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.

Jesse Rumball-Smith

Student, Wellington College, New Zealand

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.

The auto-edit is a great help and the supplementary page with the revision summary is an excellent idea.
