markscommas

markscommas is a minimalist web-based tool designed to help users improve their writing by correcting common punctuation errors, particularly those involving commas. Created as a simple, distraction-free interface, it focuses on teaching proper comma usage through interactive exercises and instant feedback.

The tool operates by presenting users with sentences containing comma-related mistakes, such as missing or misplaced commas in lists, nonrestrictive clauses, or introductory phrases. Users correct the sentences, and markscommas highlights errors and provides explanations for the correct punctuation. The design emphasizes clarity and efficiency, avoiding unnecessary features to maintain a clean learning experience.

markscommas is accessible via a web browser and requires no installation or account creation. It is often used by students, writers, and educators seeking a quick reference for comma rules or a low-pressure way to practice grammar. The tool does not replace comprehensive grammar guides but serves as a supplementary resource for reinforcing punctuation skills.

Developed with simplicity in mind, markscommas adheres to a neutral, non-prescriptive approach, allowing users to learn at their own pace. While it does not cover all aspects of grammar, its focus on commas makes it a practical tool for addressing one of the most frequently misused punctuation marks in writing.
