Monetize chatGPT by OpenAI
I actually tried this and told the AI that I was feeling down. I don't recommend going down this route with the AI as is, as not only is there no real confidentiality, for all we know the AI might tell someone to kill themselves or something. Still, I was impressed by the response as what it said offered some perspective. Not worth a professional therapists full hour rate or anything, but still valuable (maybe a few dollars).
2. Presentation Rehearsal
When I have to present to an audience, what scares me most is being asked a question that I might not be prepared for, and appearing unqualified or foolish. Being able to do a dry-run confidentially and have the AI ask me probable questions would be worth the money.
3. Writing Dialogue
If you want to play with characters having different voices, having an AI contribute to your writing may be helpful.
4. Writing Titles
Titles (and names of places/characters) can be a struggle for me. If it didn't cost much, I might be willing to pay to have the names of world details in my stories punched up a little.
5. Write my mom a letter
I try to call my mother every day, but I miss a few intervals every week. Maybe the AI could send a quick note for me occasionally. I doubt she'd notice it wasn't me.
