Log your meals by talking and get a daily weight check-in
Tell your bot what you ate, out loud, and it keeps the food log for you. It can also check in on your weight each morning.
What the bot does
- Listens when you say what you ate and writes it into a simple food log.
- Estimates the basics you care about, like calories or protein, and labels them as estimates.
- Checks in each morning about your weight (or reads it from your scale's app if you connect it).
- Sends a short weekly summary of trends.
What you end up with
A food and weight log that fills itself in, without typing into a tracking app.

Be my food and weight log. When I tell you what I ate, add it to a log with the date, time and a rough estimate of [calories / protein]; label estimates as estimates. Every morning at [time], ask me for my weight and add it. Every [Sunday], send me a short summary of the week's trends. Don't give medical advice; tell me to ask my doctor if something looks off.
