Practical workflow example

At clarify the brief and goal, use ChatGPT to get the first draft moving, then use Claude for tone and structure, and finish with Notion AI for the final pass.

  • clarify the brief and goal
  • set up draft and reply flows
  • connect QA and automation

Research and plan

Start by clarifying the brief. Use ChatGPT or Claude to narrow scope, then decide which gaps still need research.

Produce the first draft

Claude or Notion AI can be a good second step for creating the first version; the goal here is structure, not perfection.

レビュー and publish

Do one last check with Canva AI, then レビュー tone, accuracy, and brand voice before publishing.

Checklist before publishing

A good stack is not about using more ツール at every step; it is about delivering more reliably with less friction.

  • Is the product or job data accurate?
  • Does the tone match the audience and brand voice?
  • Are there repetitive claims or overhyped lines to remove?
  • Has a human reviewed the final draft before publishing or delivery?
