I built an AI writing assistant

A technical copywriter at Temporal built an internal AI writing assistant to help engineers and other subject-matter experts develop blog posts without erasing their voice or replacing human editorial judgment. Designed for the company’s Voices of Temporal program, the assistant supports distinct brainstorming and editing modes, asking questions to clarify an idea’s audience, angle, format, and takeaway before providing restrained editorial feedback on completed drafts. Rather than silently rewriting content, it creates interactive redlines that explain suggested changes, offer alternatives, and flag facts requiring human verification. The tool was developed as a Claude Project, a ChatGPT Project, and a Claude Skill to accommodate differing user workflows and platform behavior, with the Skill providing portable access within existing conversations. The author emphasizes that effective AI writing assistants should be built around a team’s actual processes, carefully tested for unwanted model tendencies such as excessive polish or generic language, and designed to preserve writers’ control over final decisions.
