AI Analysis

●MidCozy

Clean mortality calculator, but life-in-weeks visualizers already exist.

Strengths

•No backend means zero data retention — genuinely private by architecture.
•Export to PNG and JSON backup lets you share or restore sessions later.

Weaknesses

•Single-page utility with no novel technique beyond existing mortality calculators.
•SSA tables only — no international data for non-US users.

Post Description

I built this after reading “The Tail End” by Tim Urban. I wanted a simple way to understand my lifespan relative to the people most important to me.

SandsOfTi.me helps you visualize your approximate lifespan, healthy years remaining, and the time you likely left with your parents, children, spouse, and more.

Stuff of note:

- Single-page app (HTML/JS)

- No sign-up required

- Nothing you input is stored (no backend)

- Save your visualization as an image, or export your data so you can restore it later

- All lifespan estimates are based on U.S. Social Security Administration Cohort Life Tables (already considering other data sources, but using more than one standard gets complex)

Feedback and suggestions are very welcome!
