AI WhatsApp bot that remembers your relationships and automates personalized follow-ups.

My friend and I built an AI that lives in his WhatsApp and remembers everything people tell him — I just came on as co-founder and we need ~30 honest testers before we spend money on ads Quick backstory.

In all seriousness, I have, for a long time, used my own comments on social media (including HN) as part of a personal needle-in-haystack test, simply because I do know my somewhat peculiar style and what I tend to write, but also because I can sometimes write in a slightly confusing manner, ma

Would you use a brainstorming/planning/ideation tool for side projects? This is not a new idea, and I know we see posts about something similar about once a month. I do think I took it farther than others I've seen, but either way I'd still be interested in feedback on this one.
