AI Assistant
Serenity Book connects to ChatGPT, Claude, Cursor, and any other assistant that speaks MCP. You already pay for an AI. This lets it read your customer history, fill your empty chairs, and set up your services, without you clicking through a single settings page.
What it does
You don't have to know the right question to ask. These are real prompts, worded the way an owner actually types them. Once connected, the assistant answers with your customers and your calendar, not a demo dataset.
Start here
Look at my business and tell me the three things you would fix first.
A general read on your business. It will usually surface a soft weekday, a group of customers drifting away, and a service nobody books.
Learn the concepts
Explain how you decide someone is "overdue" and show me a few examples from my customers.
It walks you through the reasoning, using names you recognize, so the next campaign is one you understand rather than one you trust blindly.
Before you send anything
Who would you email this month, and why those people specifically?
The reasoning comes first, the draft second. If you disagree with the list, say so and it will re-cut it.
Pressure-test a plan
I was going to email everyone a 20% off coupon. Talk me out of it.
A blanket discount to your whole list trains loyal customers to wait for a sale. It will usually propose a smaller, targeted offer and explain the difference in what you keep.
Quiet days
Which day of the week is costing me the most money, and what would you do about it?
Utilization by day and provider, then a concrete list of customers who historically book that day.
Rehearse it
Draft the email but do not send it. I want to read it first.
Nothing sends without you clicking send. Ask for three versions and pick one.
Why this matters
The quiet Tuesday. The client who came in every month for two years and then stopped, four months ago, without anyone noticing. The vague sense that you should reach out to someone, without a clear answer to who, or what the message should say.
Most software answers this with a bigger reports page, which does not help, because the problem was never a shortage of numbers. The gap is between having the numbers and knowing who to email on Thursday. An assistant that can read your actual booking history closes it, because it can do the reading and the drafting in the same breath.
The blank page
"Send a campaign" is not a feature if you don't know what to write. Your assistant drafts the email and you edit it, which is far easier than starting cold.
The wrong list
Emailing everyone trains people to ignore you. The signal that matters is who is overdue against their own pattern, not the calendar's.
The silent drift
Customers rarely quit. They just come in less often, then not at all. That decline is visible in the data months before you feel it in revenue.
Most booking software ships its own narrow assistant and charges you monthly for it. We took the other path. Serenity Book exposes your business through an open standard called MCP, so ChatGPT, Claude, or whichever assistant you already use does the work.
You create a key from your dashboard, paste it into your AI client once, and from then on you can just ask.
One conversation, start to finish
An owner noticed empty slots in the massage schedule and wanted to know why. That was the entire prompt. Everything below is what the assistant did in response, in one conversation.
Read the catalog and the team
Three massage services (Swedish 60 at $90, Swedish 90 at $140, Deep Tissue at $120) and the two therapists able to deliver them, with their working days. No setup and no configuration. It read the live product and provider setup and worked from that.
Pick who is actually worth an offer
Rather than blast the whole list, it filtered out internal test accounts, then excluded every customer who already had an appointment booked, because discounting a visit someone was going to make anyway is margin given away for nothing. That left two: Liam, twelve massages and nothing on the books, and Noah, nine.
Build the offer so it can be measured
One code per customer, scoped to massage services only, single use, short expiry. Personal codes mean redemptions are attributable to a person instead of a guess, and a scoped code cannot be spent on something the campaign was not trying to sell.
Draft the emails
Two short personalized emails, one clear call to action, deadline in the subject line. Ready to read and send, not sent.
Push back when the owner was about to make a mistake
Asked for a permanent reusable discount code, it said no and explained why: a code that never expires trains your regulars to wait for the next deal. Spin up a fresh short-lived one each time a gap opens. When the owner switched from a percentage to a flat $15, it rewrote both codes and both emails, and pointed out that a flat amount nudges people toward the higher-priced 90-minute and Deep Tissue services, which is what these two book most.
And then it can be checked. Redemptions and total discount are tracked per code, so within a week or two the owner can see whether it filled slots and whether the play is worth repeating.
What normally takes a report export, a spreadsheet, a segmentation pass, a copywriting session and a trip into the promo settings happened in one back-and-forth. The part worth noticing is not that it answered questions. It argued against a bad idea instead of politely building it, and it ruled out the customers who were not worth a discount.
Same key, same conversation. Sixty tools across four areas.
Run the desk
Book, reschedule, cancel, confirm and check people in. Availability is checked before anything is placed, so it cannot double-book you. Leave a note on a customer that follows them forever, or on a single appointment.
Understand your customers
Who is overdue against their own rhythm. Who came once and never returned. Who no-shows repeatedly. What each person actually books, and what they have never tried.
Set the business up by describing it
Hours, holidays, early closes, services and prices, categories, providers and who does what, membership tiers, bundles. The day-one setup nobody enjoys.
Find and fill the quiet days
Utilization per day and per provider, then the customers who historically book that weekday. The two halves of that question are useless apart and only worth asking together.
Where we drew the line
This is not a setting you can accidentally turn on, and it is not an instruction we politely ask the model to follow. The payment endpoints are simply not reachable with an AI key. A model that decides to charge a card gets a locked door, not a judgment call.
Never reachable
Also true
Early access. Available on Basic and Pro.
You bring your own AI subscription, so we are not reselling you a model. Serenity Book charges only for the requests your assistant makes against your business. Every key currently includes:
5,000
requests per month, per key
60
requests per minute burst
For scale, a normal question like "who hasn't been in lately" is one request, and setting up a full week of business hours is a handful. Most owners never approach the allowance. Per-request pricing beyond it has not been set yet, and while the feature is in early access we will tell you before anything is billed.
Once it's on your account, the whole setup is three steps.
Create a key
Settings, then API Keys. Choose read-only or read and write. The key is shown once.
Paste it into your AI client
The same page gives you copy-ready setup for Claude on the web, Claude Desktop, Cursor, VS Code, or any other MCP client.
Ask it something
Start with "how did last week look?" and go from there. Revoke the key any time and the connection dies instantly.
