Udemy: AI Writing Mastery with ChatGPT and other language models

AI Writing Mastery is a Udemy course taught by Shani Raja, a former Wall Street Journal editor who is best known on the platform for his bestselling courses Writing With Flair and Ninja Writing. The course was last updated in June 2026 and covers how to produce professional written content across multiple AI models, including ChatGPT, Claude, Gemini, Grok, and Perplexity.

The course is aimed at working professionals who already know how to use AI tools at a basic level and want to move from generic outputs to polished, publication-ready writing. The intended audience includes anyone who regularly writes emails, reports, presentations, LinkedIn posts, proposals, business plans, or marketing copy, and who wants to do that work more efficiently without losing quality.

What the course covers is the craft of prompting specifically for writing tasks, rather than prompting as a general technical skill. Raja’s background as a professional editor shapes the material: the emphasis is on how to preserve voice, achieve appropriate tone for context, and get AI outputs that require less manual correction. Modules address different output formats in sequence, building a repeatable workflow rather than a set of one-off tricks.

The course does not require prior expertise with any particular model. Learners are expected to have an active account with at least one AI model, but the instruction is designed to transfer across platforms rather than being locked to one interface.

Where the course has less depth is in strategic questions — when to use AI in a writing workflow versus when manual drafting produces better results, or how to handle attribution and editorial standards in professional contexts. Those questions belong to a different kind of course. For writers who want a practical method for getting better outputs faster, the editorial perspective Shani Raja brings is a genuine differentiator from courses taught by marketers or generalists.
