After the redesign of the portfolio site, I’ll share the
3-month recordof the AI Agent usage and various questions through the portfolio website!
You can actually use it on Dewdew Dev!🤨
Before we start,
In December of last year, I redesigned the portfolio site.
As my personal information increased, I implemented a chat feature that allows visitors to directly ask and answer my information through questions and answers.

I was going to share this after more users used it,
but I found that the content was more interesting than expected, so I wrote this article earlier.
How much did I spend and how many visitors came in? (AI Agent usage)
I think this part is the most interesting part for you.
Actually, I put LLM models like GPT, Gemini, Claude etc., but the LLM model I actually used was GPT mostly.
I think this is because I can easily receive answers without changing the model selection.
Let’s take a look at the actual usage together!
Yes!
I used about $3 for 3 months.
I used about 10 million tokens.
The cost per conversation was about $0.006 (about 8.7 won), and the average monthly cost was about $0.8.
Then, how many visitors came in to the portfolio page?
Actually, since there are many different users coming in,
the usage increase is not very noticeable, but we can see that many users are accessing the new Agent-enabled route.
(It’s really amazing that many users are coming from abroad!!!!)
What questions did the actual Agent answer?
Now, let’s see how users actually used it.
Personally, this part was the most interesting part for me!
The image below is a UI generated by Claude, so it may be slightly rough.
(But now it’s getting better and better HaHaHa)
Conversation count
There were 391 conversations in total for 3 months! (from 25.12.06 to 26.02.27)
There were 116 unique questions.
Device and browser
When we look at the number of questions asked by device and browser,
We can see that the number of users using Mac is overwhelmingly higher than the number of users using mobile.
Of course, the browser is overwhelmingly Chrome.
Arc is great…ㅠㅠ
What are the most frequently asked questions?
Of course, the most frequently asked questions are the questions selected quickly.
Anyway, the top 3 on the list of 20 quick questions were future career path, recent experience, and self-introduction, which was quite interesting!
Interesting and scary questions
Personally, the questions that were interesting to me are as follows!
- Please come to our company! We’re waiting for you! Please! ㅠㅠ (HaHa.. Thank you for your interest!!)
- Haha.. Is this recorded? (Yes!!! HaHa It was recorded!!!)
There were questions that were not answered in the other questions..HaHaHa
But I’m grateful to many people who asked various questions!
Attack, Defense!!!
In fact, from the very beginning, I designed the Agent to only provide responses based on my own data in order to defend against unexpected requests.
Naturally, there was no risk of prompt injection, though there were people who still tried it, haha.
As you may have seen earlier, if an injection attack had actually succeeded, the number of tokens used would have skyrocketed—but you can tell that didn’t happen!
(Come at me bro!!!)
If you request the questions that were actually attacked, you can see that it doesn’t answer as shown below!
Conclusion
After 3 months of using the portfolio with AI Agent based on resume data,
the cost was less than expected, and the question data was much more interesting than expected!
Anyway, it was a fun experience to watch the Agent working like this!
I think you should try to create your own Agent and enjoy it!
See you next!
