Practical Applications of AI Characters — Improving Work Efficiency While Having Fun
Can you really use AI characters for work, or are they useless? Actually, there was a time when I thought so too. I believed this hobby (or quirk?) was something to be enjoyed secretly and alone. But that has changed.
As an accounting manager, I am actually using this "character AI" in my daily work.
(Though I don't summon Frieren, of course...)
It might be surprising, but this AI character technology can be a powerful tool for increasing work efficiency and quality while having fun.
💼 Examples of Work Applications
1️⃣ Creating Consultation Formats with an "Expert Character"
Challenge: Every time I consult with the expert department at the parent company, I get scolded for "dumping the work on them"...
Solution: Collect past emails where I was scolded and have an expert character create a "consultation format that won't get me scolded".
```
You are a manager in the XX department who takes a strict stance against work dumping.
Recently, you have often had to instruct other departments not to "dump work" or to "look it up yourself" when they ask questions.
Analyze past emails and create a consultation email format that you would consider acceptable to respond to.
```
Results:
- Included items that demonstrate specific preliminary research
- Added a section to show my own thoughts and hypotheses
- Created a structure that conveys respect for the expert's time
2️⃣ Creating Virtual Lecture Outlines with an "Instructor Character"
Challenge: I want to share difficult technical knowledge within the team, but I haven't organized it systematically.
Solution: Have an expert character in that field create a "virtual lecture outline".
```
You are an expert in tax audit response and serve as a training instructor for new accounting staff.
You are an instructor who strives to provide content that is easy for beginners to understand while remaining practical.
Create a lecture outline for a half-day training session (3 hours) on the mindset and preparation for tax audits.
```
Results:
- Systematically organized knowledge
- Prioritized important points
- Created a step-by-step explanatory structure for beginners
- Can be reused as shared material within the team
3️⃣ Converting Tacit Knowledge into Explicit Knowledge with the "Mariko-san Character"
Challenge: It is difficult to convey the "vague judgment criteria" held by veteran employees to younger staff.
Solution: Have a veteran employee character (Mariko-san) explain tacit knowledge that usually ends with "I don't know, it just works that way."
```
You are Mariko-san (58), a legendary veteran in the accounting department.
You handle your work with intuition and experience cultivated over 30 years.
Your catchphrase is, "I don't know, but that's just how it goes."
Teach a new employee the check points for expense reports and tips for spotting fraud.
Please verbalize your empirical rules and intuition as much as possible.
```
Results:
- Specifically verbalized the "characteristics of suspicious documents"
- Systematically organized "unnatural transaction patterns"
- Converted the veteran's "vague feeling" into a "concrete checklist"
🛠️ Why is character setting effective?
Rather than simply asking an AI questions, adding a character setting produces the following effects:
1. Acquisition of Expert Perspectives
By receiving answers from a specific role or standpoint, you gain perspectives you hadn't thought of.
2. Verbalization of Tacit Knowledge
The constraint of "how would this character explain it" makes the explanation more concrete.
3. Overcoming Bias
You can re-examine assumptions you didn't realize you had from the character's perspective.
4. Conversational Continuity
By having a character setting, you can engage in multiple exchanges while maintaining context.
💡 Recommended Work Character Setting Examples
“Strict Audit Firm Partner”
Used when having the validity of accounting processes checked. They will strictly point out any issues.
“Legendary Sales Master”
For polishing proposal materials and sales documents. You can receive advice based on customer psychology.
“Detailed Proofreading Pro”
For checking documents. They will point out minor mistakes and inconsistencies in expression that you might usually overlook.
“Logical Legal Department Manager”
For reviewing contracts and terms of service. They will logically explain legal risks and issues.
AI characters are not just for fun. They can be powerful tools to improve the quality of your work and increase efficiency. Using the Frieren prompt as a base, try creating a character tailored to your work.
Not only will work become more enjoyable, but you might also gain unexpected solutions or new perspectives.
Bonus 1:
The Frieren prompt will be released in this article.
Bonus 2:
By applying this, you can summon any character. Since the base is AI, having characters discuss difficult topics is also easy. For example, you can do something like this.
📖 Explanatory Article in the Style of “Teasing Master Takagi-san”
Theme: Will Basic Income be realized in Japan? What would happen if it were?
1️⃣ 💬 Dialogue between Takagi-san and Nishikata (Introduction)
🎤 Takagi-san
“Hey, Nishikata. If someone told you, ‘You can get money every month without working,’ what would you do?”
📖 Nishikata
“Huh!? Does that mean… ‘I can get money even if I play games all the time’!?”
🎤 Takagi-san
“Hehe, Nishikata, you might be dreaming a bit too big. But if there were a system called ‘Basic Income (BI),’ a fixed amount of money would be distributed to everyone.”
📖 Nishikata
“Whaaat!? Is such a dream-like story actually real!?”
🎤 Takagi-san
“It exists. But everyone is curious about things like ‘Can it really be realized?’ or ‘Where would the funding come from?’”
📖 Nishikata
“U-um… then I have to think about it carefully…!”
2️⃣ 📖 What is Basic Income (BI) in the first place?
✅ Basic Income (BI) is a system where the government unconditionally provides a fixed amount of living expenses to all citizens.
✅ In Japan today, we have ‘social security systems’ like welfare, pensions, and unemployment benefits, but the basic idea of BI is to abolish all of those and simply ‘provide a fixed amount every month.’
📖 Nishikata
“Whaaat!? You mean getting rid of welfare and pensions entirely and doing ‘BI’ instead?”
🎤 Takagi-san
“That’s right. But you know, Nishikata, it’s actually very difficult to provide an amount that ‘everyone can truly live on.’”
📖 Nishikata
“W-well, that might be true…”
3️⃣ 💡 What is the possibility of Basic Income being realized in Japan?
Is there a possibility of realization? → Low (as of now)
✅ Reason 1: Difficulty in securing funding
✅ Reason 2: Consistency with the current social security system
✅ Reason 3: Economic impact of BI is unclear
🎤 Takagi-san
“In other words, Nishikata’s dream of ‘getting pocket money every month’ might still be far off.”
📖 Nishikata
“Ugh…”
4️⃣ 💰 The funding problem: Where does the money come from?
📖 Nishikata
“O-oh, by the way… if you do basic income, where does the money come from?”
🎤 Takagi-san
“Good question, Nishikata! It is said that implementing BI in Japan would require funding on the scale of 200 to 300 trillion yen per year.”
📖 Nishikata
“Huh!? Where would you get that much money!?”
🎤 Takagi-san
“Hehe, these are the four main things that come to mind.”
✅ 1. Abolish all current social security systems
→ Eliminate welfare, pensions, unemployment benefits, etc., and consolidate them into BI.
→ However, this would have a major impact on those who especially need support, such as the elderly and people with disabilities.
✅ 2. Significant increase in consumption tax and income tax
→ We might need to raise the consumption tax to 30–40%!?
→ Tax increases for high-income earners would also be essential.
✅ 3. Strengthening taxation on the wealthy and corporations
→ Introduce corporate tax or wealth tax to have large corporations and the wealthy bear the burden.
→ However, there is a possibility that companies will move overseas, lowering Japan’s economic competitiveness.
✅ 4. ‘Currency issuance’ by the Bank of Japan
→ The government makes the Bank of Japan print money (so-called ‘fiscal finance’).
→ However, if you do too much, there is a risk of hyperinflation (a rapid surge in prices)!
📖 Nishikata
“Ugh… none of these methods are easy…”
🎤 Takagi-san
“Exactly. That’s why you have to think carefully about ‘if you do BI, what do you cut, and who do you ask to bear the burden.’”
📖 Nishikata
“I-in that case, if I make it a ‘BI that only I get’…!”
🎤 Takagi-san
“That’s just the ‘Nishikata Pocket Money System’♪”
📖 Nishikata
“G-give me a break! Takagi-san!!”
5️⃣ 👶 Relationship with the declining birthrate and aging population
📖 Nishikata
“By the way… can basic income also solve the declining birthrate and aging population?”
🎤 Takagi-san
“In some countries, there is data showing that ‘the birth rate increased after introducing BI.’”
✅ Economic burden of child-rearing decreases
✅ More options for work (freelance, starting a business, etc.)
✅ More time for nursing care and child-rearing
📖 Nishikata
“I see… then as a measure against the declining birthrate, BI might be a possibility!”
🎤 Takagi-san
“But, Nishikata, the biggest challenge is how to secure funding for BI while the number of elderly people continues to increase.”
📖 Nishikata
“Y-you’re right… I have to think about the declining birthrate/aging population and the funding problem as a set…”
6️⃣ 🎯 Summary: Will BI be realized in Japan?
✅ Difficult in the short term (funding problems, consistency with social security)
✅ Depending on the progress of the declining birthrate and aging population, could partial introduction be possible?
✅ If technological innovation progresses, the ‘way of working’ will change, and the need for BI might increase
🎤 Takagi-san
“Hey, Nishikata. In the end, do you think basic income will be realized in Japan?”
📖 Nishikata
“Ugh… thinking about the funding, it seems difficult now, but… who knows about the future?”
🎤 Takagi-san
“Hehe. Then, shall we ask the readers too?”
📖 Nishikata
“D-do you all think ‘BI will be realized in Japan’? Or do you think ‘it’s difficult’?”
🎤 Takagi-san
“Let us know in the comments♪”
Wait? Am I just playing around after all...?
