Food journaling
Log food by voice, text, photo or barcode.
A sentence is enough for a meal. For packaged foods, scan the barcode to bring the matched product's nutrition facts into the conversation. Then log an amount, compare products or ask how one fits a goal you set.

Frequently asked questions.
What can I track with KnowsYou?
Meals, workouts and activity, goals and the habits behind them, treatment routines, lab reports and doctor's instructions — plus the personal context you want remembered. Everything is logged from one chat and lands in its own page.
How do I log a meal?
Type a sentence, say it out loud, add a photo or scan a packaged food. KnowsYou estimates nutrition for descriptions and photos; a barcode brings in nutrition facts for the matched product. If a detail is off, reply and the record updates. See how meal estimates work.
Can I chat in my own language?
Yes. The interface is available in English, German, Polish and Romanian, chosen in Settings, and the agent converses in your preferred language — just tell it which one.
Does KnowsYou work with wearables?
WHOOP is connected today: recovery, sleep, strain and workouts land in the same journal. You can request the next integration on the roadmap.
Is KnowsYou a medical app?
No. KnowsYou is a general-wellness journal: it records and organizes what you tell it and what you upload. It does not diagnose, treat or replace your clinician. Read the safety boundaries.
Can other AI tools write to my journal?
Yes. Create a personal key and connect ChatGPT, Claude Code or Codex — so the tool you use for research can read what actually happened, instead of you retyping it. Details on agent access.
Where does my data go?
Chat, voice, files and WHOOP each take a separate, documented path. The data & security page maps every one of them.
How much does it cost?
Nothing while KnowsYou is in beta — create an account and start logging, no card needed. Any paid plan later comes with 15 days' notice (pricing). The Android app is on Google Play; on iPhone, the web app works well and can be added to the Home Screen.
Where did I get 33 g of sugar today?
Mostly from breakfast. The fruit yogurt had about 16 g and the banana 12 g. The other 5 g came from milk in your coffee.
Your next meal can be the first entry.
