How is Trinka different from regular grammar checkers?

Most grammar tools claim they don’t use your content for AI training, but they still store your data on their servers which means it can be accessed, exposed, or retained without your control. Trinka works differently. Your content is processed and deleted in real time, never reaching our servers or leaving your computer.

Along with ensuring complete data privacy, Trinka enhances your writing style, sentence flow, and academic tone while checking citations and even flagging retracted papers. It also supports both English and Spanish, making it a truly global grammar checker built on trust and transparency.

Writing is rarely perfect, but it’s always improving. Trinka is simply there to make that journey a little smoother by helping you focus on your thoughts while it takes care of the details that matter. So, don’t miss out on this exciting Black Friday deal. Click here to get started for free and use the code BF30 to get 30% off on all upgrades.
