About "AI担当くん"
What is AI担当くん?
AI担当くん (AI Tantou-kun) is a training and hands-on support service for embedding generative AI in day-to-day work, run by Sun Asterisk Inc. (Sun*), a company listed on the TSE Prime Market. It helps companies put existing generative AI tools such as ChatGPT, Claude and Gemini to work on everyday tasks like paper forms, Excel, internal inquiries and report writing.
The official site says it "prioritizes using existing AI and SaaS rather than starting from development," and training-only or on-site-support-only engagements are possible. It mainly targets companies at the stage of "we handed out ChatGPT but only a few people use it" or "we can't decide where to start." New-business ideation (AIdeation) and AI-driven contract development (using MoMorph) are offered separately as Sun corporate services.
Support at a glance
How the engagement works
The official site shows four steps from consultation to adoption.
30-minute consultation
Hear the current situation and issues, and sort out the first questions to tackle
Quick diagnosis
Visualize where the company stands with AI, based on interviews
Proposal
Present a mix of training and support with a rough estimate
Start and embed
Start small and stay alongside until AI is built into the work
The content follows the order: know where you are → raise the baseline with company-wide training and rules → narrow down effective tasks through department diagnoses → embed through team-level support.
Service menu
01Diagnosis
Deciding where to start.
- AI adoption self-diagnosis — 6 questions, about 1 minute. Shows the current state from 5 perspectives
- Interview diagnosis — Checks usage rate, literacy and rule setup
- Department-level diagnosis — Narrows down high-impact tasks by department, such as accounting, sales and general affairs
02Training
Giving everyone a foundation to start using AI.
- AI utilization training — Generative AI basics, use in work, usage rules. E-learning and in-person group training
- "Hand work to AI" practical workshop — For non-engineers, about 1–1.5 hours. Experience the plan–ask–execute–verify flow with AI agents such as Claude Cowork or Codex
03On-site support and adoption
Making sure AI is actually used after training.
- Team-level support — Works inside the team until AI is built into the work
- Four easy starting themes — Sorting and transcribing forms, drafting answers to internal Q&A, drafting reports and weekly updates from meeting notes, and department adoption programs with usage rules
- Light implementation — Connects only what existing AI and SaaS cannot cover
04AI-related services from Sun*
Where to go for new business or development.
- AI*deation — Generates, evaluates and refines business ideas using generative AI and Sun*'s own framework. Three plans: Light / Standard / Premium
- AI-driven development (MoMorph) — Links Figma designs with specifications and sets up the process from test-case generation to AI implementation

Track record and case studies
The AI担当くん case page introduces three generative AI projects by the operator, Sun*.
01AI-driven development — Benesse Corporation
Built a development flow in which AI handles design through implementation and automated testing, using MoMorph. Three months into the project, productivity rose 39% (target 50%), and about 80% of newly added code was AI-generated (case published in 2026, official).
02Generative AI prototyping — cotobox
Built an interactive mockup of an overseas trademark search service, cutting a process that usually takes at least 4 months to 2 months. It led to sales leads with about 300 companies from about 73 countries at INTA2025 in May 2025 (official).
03Generative AI ideathon — Sojitz Tech-Innovation
Designed and facilitated a 2-day ideathon on January 27–28, 2026 for about 20 people in 4 teams. Using AI*deation and Ailla, all 4 teams presented ideas aimed at commercialization (official).
The AIdeation page also includes comments from POLA Inc. and PFU Limited. For Sun as a whole, the official site states "business support for 500 companies and 850 products" (no date given).
Who it suits and who it doesn't
Suits companies that
- Handed out generative AI accounts, but only a few people use them
- Want to start small in departments heavy with paper, Excel, internal inquiries or reports
- Prefer to set up how they use existing AI and SaaS, and the rules around it, rather than build new systems
- Want to order only part of the support, such as training only or on-site support only
Does not suit companies that
- Want a large custom AI system built from the start (Sun*'s development services are the entry point for that)
- Want to compare published prices in advance (on-site support is quoted individually)
