Copywork is a web app designed to help writers improve their skills by practicing a proven writing method: copying the work of great authors. It allows users to upload any text and copy it word-by-word, absorbing the style, structure, and flow of the writing without distractions.

The app’s overlay editor places your writing space on top of the original text, letting you focus solely on mimicking the author’s style. This process helps develop a unique writing voice, overcome writer’s block, and enhance vocabulary—all while avoiding the common pitfalls of overthinking and perfectionism.
