Supplementary Explanation

Order of Using Tools

I use tools in the following order. The reason why I settled on this form became clear after my presentation. I think this is almost the same order as when humans create proposal documents, etc. Hearing → Summarizing content based on facts → Expanding content with hypotheses based on facts → Creating documents

1. Google Document (Hearing)
2. NotebookLM (Summarizing content based on facts)
3. Gemini Gem (Expanding content with hypotheses based on facts)
4. Vercel v0 (Creating documents)

Is Vercel v0 Necessary?

Now that I think about it, apps can be created with Gemini Canvas, so that would have been fine too.
Next time, I'd like to try it and compare the results in a blog post.

Conclusion

Various AI services are emerging, so I want to keep up with the latest services and enjoy working with them!!
