At a job advertising agency in Japan, about 62 employees built their own AI tools for their own work through hands-on training.
Challenge: Over 60% used Gemini almost daily, yet their confidence in using it well averaged 2.4 out of 5 (pre-training survey).
AI's role: In four sessions totaling 12 hours, each person built Gems and Google Apps Script automations for their own tasks and presented the time saved.
Results: Tools built: 65. Time saved: approx. 200 hours a month (sum of trainees' own estimates). Training satisfaction: 4.60 out of 5 on average.
What made it stick: Setting clear rules on what information can go into AI, taking inventory of tasks, and hands-on sessions using each person's own work, followed by presentations.
People lead; AI walks alongside. With the approach 'don't write from scratch: let Gemini draft, people refine,' employees improved their own work.
