For service businesses that run on repeat clients
Stylists, groomers, trainers, cleaners, massage therapists, tattoo artists — any business where the same people come back and send their friends. WarmBook is a daily coach inside the AI you already use: it knows your client book, tells you who's quietly drifting before they're gone, and drills the five conversations that actually grow the business. One client, one genuine reason — never a blast.

The problem it solves
A client who loved their last visit gets busy, misses their usual rebooking window, tries somewhere closer to work — and a year later you realize you haven't seen them since spring. Almost every lost client in a service business is lost to silence, not dissatisfaction. WarmBook's answer: know everyone's natural return cycle, watch who's slipping past it, and reach that one person with something real before someone else gets them.
Who's in today (and what you remember about them), who's cooling and needs one warm reach, which gap in your week could be filled by a client who's already due. Every morning, before your first appointment.
One question — "how often does a good client come back?" — sets the clock. One cycle overdue = cooling. Two = drifting. Three = probably gone. The radar surfaces them while they're still yours to keep.
Your client list as a real asset: who found you how, what they like, when they're due back, who referred whom. Kept in your own browser, on your device — your data, not ours.
The method
WarmBook isn't a contact app — it's a coach. It role-plays these with you, in your own voice, until they're automatic:
The highest-leverage moment in your week is a happy client standing in front of you. Two good options beat one open question — and the next visit is booked before the door closes.
A warm, specific, personal reach to the one client slipping past their cycle. Never a "we miss you!" blast — those teach people to ignore you.
Ask when they're admiring the work — with a specific, picturable ask. Then thank every sender, every time, so one referral becomes a habit.
A cancellation isn't lost time — it's an opening aimed at whoever's already due. The Book knows who'd take it; offering it reads as a kindness, because it is one.
Grace once, warmly. Name the held time without shaming. Rebook in the same breath. The relationship survives; the boundary stands.
Even with no fixed rhythm (tattoo work, project trades), the referral engine carries the value: every happy client is a doorway to the next three, and the Book tracks the chains.
How it works
Your dashboard lives at app.warmbook.app — open it on any device, sign in once with your license key, and it's all there: the client Book, the going-cold radar, your weekly scoreboard. No download, no setup, no IT. And the same key puts the coach inside the Claude or ChatGPT you already use — briefings, the five drills, ready-to-adapt scripts, role-played in your own voice.
The rules the coach never breaks:
It never sends anything — you draft, you send, in your own voice. It never does mass messages — one client, one genuine reason, every time. And your client list stays yours: the connector serves coaching content to your AI; your data never lands on our servers.
Founder pricing
Run the numbers on one regular: if their visit is worth $75 and they come back every 3 weeks, one saved drifter covers the year.
Questions
A paid Claude account (Pro or Max) — or ChatGPT once our app-directory listing clears review. WarmBook's coach runs inside your AI subscription; we never see your conversations. Setup is about five minutes: the setup guide.
The test is simple: do the same clients come back, and do referrals matter? Stylists, lash techs, barbers, groomers, trainers, massage therapists, cleaners — dead center. Irregular-rhythm trades (tattoo, project work) still get the referral engine, the client Book, and the drills; the cycle radar just matters less.
Yes — export a CSV from whatever you use (Square, Vagaro, GlossGenius, a spreadsheet…) and import it right in the dashboard. The file is read in your browser, matched to your Book, and de-duplicated — it never touches our servers.
With you. The dashboard keeps your Book in your own browser on your device — our servers never receive or store your clients (there's a one-tap backup button; use it). The coaching connector only sends briefings, drills, and scripts to your AI when it asks.
Never. The coach drafts with you and you send everything yourself, in your own voice. And it refuses mass-blast requests on principle — one client, one genuine reason, is the whole method.
No. Your dashboard is a website — app.warmbook.app — that works on your phone, tablet, or computer. Sign in with your key and you're in. The coach connects inside Claude or ChatGPT with the same key (about 5 minutes, guided).
The coaching stops — no more briefings, drills, or scripts. Everything you built with it (your client Book, your notes, your files) stays with you. We gate the coaching, never your information.
