Frequently asked questions for trainers
Answers to the most common questions before getting started.
Will my clients see that I use AI or will they think it's me?+
Your clients see your brand, not Fitai. The AI generates drafts that you review and personalize before sending. They receive the final result with your name and style.
Can I edit the workouts the AI generates before sending them?+
Absolutely. The AI gives you a starting point based on the client's profile. You adjust exercises, sets, loads and whatever you need before publishing.
What happens if a client doesn't use the app?+
They receive automatic reminders. Plus, you can see who's active and who's not from your dashboard, to follow up manually if you prefer.
Can I import my current clients from Excel or another app?+
Yes, upload your client list from CSV or Excel in one click. Our team guides you through migration if needed.
Does Fitai take a commission on my payments?+
Only the basic plan has a small commission. Higher plans reduce or eliminate it. Payments go directly to your Stripe.
Do I need technical knowledge to set up my app?+
No. Upload your logo, choose colors and you're done. In less than 10 minutes you have your personalized app running.
