You sell your time and your knowledge. Not your patience for admin.
A coach, a trainer or a therapist spends an absurd share of the week doing what software should be doing: offering slots, confirming, reminding the day before, chasing a deposit, resending a link, working out who paid for what. Nobody is billed for that work, and it grows at exactly the rate your practice does.
Existing tools cut the problem into separate subscriptions. One service for the calendar, a second for payment, a third for emails, a fourth to host the content, and none of them really talks to the others. You pay four times, you copy by hand between the four, and your brand disappears behind your suppliers'.
Kubbler brings it all into one application, yours. The technical platform is already written by engineers: student accounts, booking, Stripe payments on your own account, automatic reminders, files, hosting. You describe your offer in plain words, the AI assembles the pages and the journey, you adjust with the mouse. Your students book, pay and find their content in one place, in your brand.
Four subscriptions that ignore each other, or one application.
Here is what a trainer assembles today to sell a session online, and what is left of it once the platform already exists.
What runs while you are teaching.
A trainer has no back office. They need booking, payment and reminders to happen without them: that is exactly what the platform takes on.
What happens without you
The admin that grows with your practice, and that nobody pays you to do.
Student accounts
Sign-up, sign-in, forgotten password, access reserved for members. The screens are included.
Payments and deposits
Per session, as a deposit or by subscription, on your own Stripe account. Failed charges and dunning are handled.
Confirmations and reminders
Booking confirmation, reminder the day before, invoice, follow-up: written, translated and sent at the right moment.
What you keep in hand
Your teaching, your content and your brand, without ever depending on a platform to change a word.
Your pages and prices
A piece of copy, a price, a slot, a photo: you change it with the mouse and you see the result immediately.
Content and documents
Materials, replays and files dropped into the student area, reserved for those entitled to them.
Your brand
Logo, colours, typography: set once, applied everywhere, in light theme as in dark.
What you can build with it.
Three ways to sell what you know online, without handing your practice to four suppliers.
An online session calendar
Your availability, the booking itself, the deposit taken at booking time, the confirmation and the reminder the day before. Cancellations and reschedules handle themselves: you stop chasing anyone.
A programme by subscription
A monthly coaching plan, a followed group, a trial formula: the student subscribes, billing replays on its own, and you can see at a glance who is up to date.
A student area in your brand
Materials, replays, exercises and documents, filed by programme and reserved for those who paid. Your name on the door, not a platform's.
How it works, concretely.
Four steps, three actors: you, the AI that interprets, and the engineers who wrote the platform everything rests on.
You describe your offer
In plain words: what you teach, by session or by programme, at what price, with which slots and which content. No specification document, a conversation.
The AI assembles the journey
It turns your description into pages, a calendar and a student area, choosing from 81 interface blocks that are already designed. It invents no foundation: it composes with what exists.
The platform runs the admin
Student accounts, booking, Stripe payments, confirmation and reminder emails, files, backups: those bricks were written, reviewed and run in production by engineers, before you, for every project. They are never generated.
You adjust and open bookings
You fix a piece of copy, add a slot, change a price, then you publish. Domain name, HTTPS certificate and backups are included: your students book the same evening.
Why Kubbler, when you teach.
Four concrete reasons, which come from how the product is built, not from a marketing promise.
You get your evenings back
Booking, the deposit, the confirmation and the reminder happen without you. This is not time shaved off a task: it is a whole slice of your week leaving your calendar and not coming back.
The foundations are written by humans
The AI never generates the payment, the security or the database of your application. Those bricks are written, reviewed and run in production by a team of engineers, and fixed for every project at once. You get a level of engineering a trainer could not afford alone.
Your students are your students
Your domain name, your brand, your list, your Stripe account. No platform sits between you and the people you teach, and the code exports to GitHub at any time.
One subscription instead of four
Calendar, payment, emails, content area and hosting live in the same product. Free during the beta, then a clear monthly plan, cancellable at any time, with no infrastructure bill on the side.
The questions we get asked.
Precise answers, because decisions are made on facts, not on promises.
Yes. You describe your offer in plain words in a conversation, the AI assembles the pages, the calendar and the student area, then you adjust everything with the mouse: copy, prices, slots, images. The code exists and belongs to you, but you never need to open it.
They pick a slot on your site, create an account and pay online, per session or by subscription. The payment runs through Stripe, on your own account: the money reaches you with no intermediary. The confirmation and the reminder the day before go out on their own.
Yes. The platform handles the one-off appointment as well as the monthly subscription, the trial period, the plan change and failed payments. Many trainers sell both in the same place.
In the student area of your application, filed by programme and reserved for those entitled to them. Files are stored with the project, backed up, and served behind the same accounts as the rest: there is no file-sharing service to connect.
Cancelling and rescheduling happen from their account, within the rules you set, and free the slot. You have no message to process and no calendar to fix by hand.
Your application has its own database, isolated from other projects, hosted in Paris at Scaleway, with automatic backups. Accounts come with two-factor authentication and suspicious-device detection, with nothing to configure.
Your students can book tonight.
Free during the beta, no card required. Describe your offer in a few sentences, and leave with an address to give your students, not with a mockup.
