Line Editing
Bring clarity and cohesion to your message. Line editing refines your writing at the sentence level, improving flow, tone, and word choice.

Copyediting
Make your communications polished, consistent, and credible. Copyediting ensures your content is grammatically correct, aligned with your preferred style guide, and ready for design or publication. It’s a great fit for materials with multiple authors or several rounds of revisions—grant proposals, donor briefs, newsletters, and more.

Proofreading
Final polish before going public. Proofreading is the final review to catch minor errors and ensure your document is clean and consistent. This step is essential for materials headed to layout or already in design, especially printed reports, fact sheets, and promotional flyers.
