Microcopy

Microcopy refers to the small pieces of text found throughout a product, such as button labels, tooltips, error messages, and form instructions. These short snippets guide users, provide context, and enhance the overall user experience by ensuring clarity, reducing confusion, and maintaining a consistent tone of voice throughout the interface.

Microcopy is where product personality lives — it's what makes your product feel like it was made by humans who care, rather than assembled from generic UI components. More practically, the right error message reduces support tickets, the right button label increases conversion, and the right empty state drives action. Microcopy has a disproportionate impact relative to its implementation cost — rewriting 10 labels in an afternoon can measurably move metrics.

Todoist's error screen reads 'That filter query isn't quite right...' with a friendly illustration and an 'Edit Query' button — a branded, human error message that gives users a clear next step rather than a raw error code.
