Your first result
Your starting point first. More context when you’re ready.
Age, region, and applicable sex select the population reference. Your result appears before sign-in. Add optional health details later to support more relevant suggestions.
Photo meal analysis
Photograph a meal. See what's actually in it.
Til100 turns one photo into an editable calorie range, macro breakdown, and itemized foods. Only what you confirm enters your daily nutrition.
Portions, oils, sauces, and hidden ingredients can change the estimate. One meal never changes Current Path.
Today Signal
See how today compares with your own baseline.
Today Signal compares recent activity, sleep, resting heart rate, and HRV with your own baseline. It is a daily state—not your age and not a clinical score.

Daily state only. Missing or stale history is treated as unknown: Til100 shows Not enough data, never a low score. It does not directly change Current Path. Daily metrics use your baseline, your plan, applicable public guidance, or an honest no-target state—not a universal 10,000-step rule.
Your checkup history
Turn years of checkups into one clear history.
Share or upload a PDF or photo report. Til100 automatically adds source-verified health results—not only a short biomarker list. Numbers become dated charts; written findings keep their original wording.
Every result keeps its date, unit, reference range, report page, and source. Sparse numbers stay as real points—missing years are never invented.
Til100 Agent
One agent connects your data, the research, and your next step.
Til100 Agent is a longevity agent that observes the health context you allow, retrieves reviewed evidence, routes lifespan questions through approved prediction models, and keeps the complete basis beside every answer.
Grounded in reviewed research—not an opaque fixed formula or a language model guessing your age. The agent never invents lifespan years or changes your plan without approval.
- Data usedTime window, connected source, and coverage stay visible.
- Research usedOnly reviewed evidence can reach an answer.
- Model & controlThe approved, versioned model owns the number; you approve every plan change before we apply it.
