Case Overview & Background

Tony Dong, a Vancouver-based freelance writer who mainly covers exchange-traded funds for outlets such as U.S. News & World Report, USA Today and TheStreet, made CA$149,000 in 2022. Business Insider reported he was on track for CA$238,000 (about $180,000) in 2023 while working fewer hours, and credits GPT-4 and other tools for part of that.

How AI Is Used

He uses GPT-4 in the early phase of each article to consolidate research and generate an outline with titles and subheads, then writes the piece himself. He told Business Insider he does not use it to write articles. He also uses Grammarly for tone and sentence structure and Dragon Professional for dictation.

Step-by-Step Process

Step 01Research with GPT-4

He asks GPT-4 specific questions about the topic and checks the sources it links.

Step 02Outline

He asks for an outline with titles and subheads.

Step 03Write it himself

He takes over fully for the analytical writing.

Step 04Polish

He runs drafts through Grammarly before sending them to editors.

Limitations, Risks & Failure Modes

What may not apply to you, and what could go wrong:

  • The figure is total freelance income, so it does not isolate what AI added
  • The 2023 figure was a projection in December 2023
  • Results depend on a specialist niche and existing editor relationships
  • He warns that GPT-4 cannot yet write analytically in a voice readers understand

Key Takeaways

  • AI saved time on research and structure rather than replacing the writing
  • Specialist knowledge kept his rates high
  • Fewer hours, not more output, was his goal
