AI-drafted check-in replies in your voice. Adherence score, risk flags, and a ready-to-send reply in under 15 seconds.
Jamie! Solid week. 4 sessions and clean nutrition Monday through Friday shows real consistency. One dinner doesn't undo that. 0.3kg down is the direction we want. Let's keep the same targets this week and use Saturday as a reason to be more dialled in, not less…
The problem
You already know the problem. Here's what coaches tell us every week.
"I spend 3 hours every Sunday on check-ins."
Twenty clients, twenty replies. By reply fifteen you're copying yourself, and you know it.
"I missed a client's burnout signal until it was too late."
It was buried in paragraph three. You skimmed, you missed it. Signals like that should be surfaced automatically, not depend on whether you're having a good day.
"ChatGPT replies sound nothing like me."
Generic AI output screams AI. Your clients chose you for a reason. The reply has to sound like you: blunt, warm, or whatever your style is.
"Every new client makes the problem worse."
You want to grow to 30 clients. But that's 30 check-ins to write. Without a system, growth means more Sunday dread.
How it works
Paste the check-in
Drop in whatever the client sent: a paragraph, or a full WhatsApp, Telegram, or iMessage thread. CoachTone handles both.
Summary · Thread5 agents on one job
Adherence analyst and risk flagger run in parallel on the check-in. A strategist picks the focus. A writer drafts the reply in your voice. A voice verifier scores the draft against your fingerprint and regenerates if it's off.

FAQ
The voice fingerprint is the whole point. CoachTone extracts how you actually write (sentence length, energy, how you praise, how you challenge, your characteristic phrases), and a voice-verifier agent scores every draft against that fingerprint before showing it to you. If it scores below threshold, the draft is regenerated automatically. And nothing ever auto-sends. You read every reply, edit anything that's off, and copy it into your own channel. Anything that doesn't sound like you never reaches a client.
ChatGPT is a general writing assistant. CoachTone is a 5-agent pipeline built for one job: weekly fitness check-ins. It already knows your voice (extracted from your real messages), scores the client's adherence against last week's targets, flags risk signals like burnout, injury, or dropout automatically, writes replies in your style, and verifies the draft against your voice fingerprint before showing it to you. You'd spend 5 minutes prompting ChatGPT for each reply. CoachTone does it in 15 seconds.
Every reply is a draft, not a sent message. You review it in the editor, tweak any word, sentence, or paragraph, and only then copy it into Instagram, WhatsApp, or wherever you message clients. Every edit you make is fed back into your voice fingerprint, so the next reply lands closer to right. The product gets more accurate the more you use it.
You paste real messages you've sent to clients. CoachTone extracts 13 dimensions of your writing style into a structured fingerprint: sentence length, energy, how you praise, how you challenge, and more. Every time you edit a generated reply, that edited version is fed back in automatically. The more you use it, the more accurate it gets.
Two: Summary (client writes a paragraph or message) and Thread (paste a raw WhatsApp, Telegram, or iMessage conversation, timestamps and all, and the AI extracts only the client's content). Raw check-in data is never stored. Only the cleaned summary.
Yes. We process check-in text to generate the analysis, then store only the cleaned summary, not raw conversations. Your account data is stored in a secure EU database. We're GDPR-compliant and you can delete your account and all associated data at any time.
Yes. The voice training means it adapts to how you communicate, not the other way around. Direct and blunt? It learns that. Warm and supportive? It learns that too. The scoring and strategy logic is universal; the reply style is yours.
Yes. Monthly billing, cancel anytime from the billing page. No contracts, no cancellation fees. Your data remains accessible until the end of your billing period.
I built CoachTone after watching online coaches lose every Sunday to check-ins. No team, no investors, no marketing budget. Just me, writing the code and answering every email.
