Questions?

We’re glad you asked.

What does TrainerChat actually do?

TrainerChat is an AI sales setter for fitness coaches. It replies to inbound DMs in your trained voice, runs an 11-state qualification funnel, and routes sensitive moments to draft for your approval. It works across Instagram, Facebook Messenger, WhatsApp, SMS, and Email.

Who is this built for?

Fitness coaches running paid traffic to a coaching offer, doing roughly $10k+/month in revenue. Could be 1:1 high-ticket, group programs, memberships, or hybrid models. The common thread is: you have a working funnel and you want your AI to sound like you, not a chatbot.

How is it different from generic AI tools?

Generic AI tools fire instant replies in templated voice and get caught as bots within three messages. TrainerChat trains on your actual DMs, runs human-realistic reply timing, and routes sensitive moments to draft. It's built specifically for the platform-survival realities of running an inbox at coach volume.

WIll my social account get banned?

Generic AI tools that fire instant replies and lie about being AI get accounts removed. TrainerChat is designed around platform compliance: human-realistic reply timing, send caps, jitter floors, and force-draft routing on sensitive moments. We can't promise zero risk, but the system is built to keep you on the right side of platform rules.

How do I join the beta?

Apply through the Join Beta page. Pick the path that fits how you want to ship: Guided (4-week structured onboarding) or Self-Serve (your own pace, async support). Both are free trials.

What happens after the beta ends?


You'll have the option to convert to a paid plan at our launch pricing. No auto-charge, no surprise billing. If you don't convert, your account pauses and you can come back later.
