I’ve been experimenting with how much of our personality is encoded in the data we generate every day. We all have a digital exhaust—years of emails, texts, and chat logs. I figured, if I could distill 10 years of my own communication into a small, specialized model, I could create a personal AI that sounds like me.

The result is a 73 MB LoRA “voice cartridge” that makes stock Gemma 4 E4B text like me—blind-judged 31/40 times over its base model.
