About LUMI Alignment
LUMI Alignment is a free web service that reads your personal AI usage style from your date of birth and turns it into a practical playbook. The same AI produces different results for different people — the difference is you.
How it works: enter your date of birth and a quick check-in of your current state. Everything is computed inside your browser — no sign-up, and your birth data never leaves your device.
34% of U.S. adults have already used ChatGPT — about double the 2023 share — and 28% of employed adults use it for work. Yet the same AI produces very different results per person: in one field study the average productivity gain was about 14%, while individual gains ranged from over 30% to near zero. AI is no longer about whether you use it, but how.
