An AI training coach that speaks your language

What the coach writes in your language

• Every chat reply. Ask to move a run, ease a week or explain a session, and the answer and the list of plan changes come back in your language.
• Your plan’s explanation. The message with your first two weeks, and the reason behind each new week, including the week the coach plans on its own every Sunday evening.
• Feedback after every workout. What went well, how close you were to the targets and what comes next, sent as a notification when your watch syncs.
• Recovery advice. One line for today’s workout from your HRV, resting heart rate and sleep.
• Notifications. Written in your phone’s language.

What you can write in your own words

Onboarding asks for your current fitness in your own words, so “10 km en 48 minutos” or “FTP 230, Halbmarathon in 1:45” work as well as English. Notes for the coach, such as “no runs on Mondays” in any language, become rules it follows in every week it plans. And anything you type in the chat, from “I slept badly” to “I’m travelling on Saturday”, is understood in the language you write it in.

How the coach picks the language

1. It answers in the language of your last message. Write in another language and it switches with you.
2. Before you have written anything, it uses your phone’s language.
3. App buttons such as “Plan my week” or “Ease today” never change the language of the reply.

Same coach, same rules, in every language

The language changes the words, not the training. Every week follows the same rules: about 80% easy, at most two hard days and never back to back, no more than 10% extra volume a week and a recovery week after three build weeks. Load, Fitness, Fatigue and Form are computed in code, and your paces, watts and heart rates come from your own thresholds.

Questions about languages

Which languages does the TextFit coach speak?

The coach replies in the language you write to it in, which covers most languages: Spanish, German, French, Italian, Portuguese, Dutch, Polish, Lithuanian, Swedish and Japanese among them. You don’t pick a language anywhere; you just write.

Is there an AI running coach that speaks Spanish?

Yes. Write to TextFit’s coach in Spanish and it plans, explains and adjusts your training in Spanish, from 5K to marathon and for cycling, swimming, triathlon and strength. Your workouts still go to your Garmin or Apple Watch with your own paces, watts and heart rates.

Can I switch languages in the middle of a conversation?

Yes. The coach answers in the language of your last message, so if you write in German today and English tomorrow, it follows you. Your plan and your history stay the same.

What language is my first plan written in?

In your phone’s language. Before you have typed anything to the coach, it uses the first language set on your phone for the message with your first two weeks and for your notifications.

Are the training rules the same in every language?

Yes. The language only changes the words. About 80% easy training, at most two hard days a week, no more than 10% extra volume a week and a recovery week every fourth week apply in every language, and a validator checks every week.

What language are the app’s screens in?

The app’s menus and buttons are in English; everything the coach writes to you is in your language.
