Hydrogen

Your fatigue and focus data, asked in plain English — powered by Sarenica.

Hydrogen

Built for real desk work.

Hydrogen reads sessions, fatigue load, focus blocks, and wearable joins together — so the answer points at what actually shifted in your week, not a generic productivity score.

Compare my last 14 days to the previous 14.
Strongest shift: the 14:00 fatigue dip got 22% deeper. Best block moved from 09:45 to 10:30. Tracked coverage held at 84% across both windows.

Inside the app

Ask. Compare. Decide.

Hydrogen sits inside the Windows app next to your data. Every answer cites the sessions and windows it used, so you can verify the read.

The same agent across your reports.

Daily, weekly, or one-off questions — Hydrogen reads from the same baseline. The answer is consistent across surfaces because it is computed from the same sessions.

Daily check-in

Short read after each tracked day. One thing that worked, one thing to try tomorrow.

Weekly comparison

This week vs last. What shifted, what survived, where coverage was honest.

Custom questions

Compare arbitrary windows. Ask about a single signal. Audit a hypothesis.

Hydrogen does not invent a story about your week. It points at the signals that already changed.

01
Grounded in your data

Every answer cites the sessions, weeks, or signals it used. No vague generalities, no advice scraped from elsewhere.

02
Honest about coverage

If a window has too little tracked data, Hydrogen says so before answering. No false confidence.

03
Tuned for desk work

Reads sessions, fatigue, focus, posture, and wearable joins together. Not a generic productivity bot.
