Journal into cheap local LLMs to build the most valuable personal dataset you'll ever have
measuringdistance · reddit · 2026-09-05
A Reddit poster proposes a simple but underrated practice: journal daily into a local LLM — what you did, ate, where you went, how you felt.
- Running locally guarantees absolute privacy; handing this data to a cloud company would be their holy grail
- Even C-tier small models suffice — the value is in accumulated personal context, not model capability
- Time is the only barrier: start now, and in years you'll have a profile that truly knows you, ready for future agent products
It's essentially building the data foundation of a lifelong personal agent at near-zero cost.
