What is SmartCookie? The app for private language teachers

Lessons in Google Calendar, payments in your bank, notes in a notebook and everything else in your head? That's why SmartCookie exists: a web app for language teachers who teach on their own and for small academies. Here's what it does, who it's for and what it costs, told by the people who built it.

What is SmartCookie?

SmartCookie is a web app for language teachers who teach on their own and for small academies. It brings your calendar, booking link, lesson notes, students, lesson packs and payments into one place. It costs €19 a month, with a 14-day free trial and no card needed. It's not a marketplace: it organizes the students you already have.

Who is SmartCookie for?

SmartCookie is for language teachers who teach on their own, online or in person, and for small academies and teams of teachers who share a calendar.

If you have students, teach lessons and charge for them, it's for you. We built it from real language lessons (mine, for 9 years), so that's where it fits best, but it works for any subject. Teaching on your own? Start with SmartCookie for private tutors.

SmartCookie is a good fit if you

  • already have students and want to stop jumping between apps
  • lose hours chasing payments and keeping track of packs by hand
  • run a small academy or a team of teachers

Look for another option if you

  • need a platform that finds you new students
  • need to issue legal invoices from the app
  • only need a free booking link and nothing else

What does SmartCookie do?

SmartCookie brings the admin side of teaching into a single app: calendar, booking link, lesson notes, student records with packs, payments and a private portal for each student.

What each SmartCookie feature does
FeatureWhat it does
Student portalYou share a link and each student logs in with their email to see their lessons, the notes you share, their packs and their payments. Goodbye to "how many lessons do I have left?"
Intelligent calendarPlan all your lessons in one calendar that syncs with Google Calendar.
Booking linkYour students pick a free slot and book on their own, with no back-and-forth messages (or WhatsApps at 10pm).
Lesson notes & trackingWrite down what you did in each lesson and pick up right where you left off, without relying on memory.
Student managementKeep each student's details, packs and attendance in a single record.
Student paymentsRequest payments by card or Bizum and see at a glance who has paid.

Each feature has its own page: Student portal, Intelligent calendar, Booking link, Lesson notes & tracking, Student management, Student payments.

How much does SmartCookie cost?

SmartCookie costs €19 a month for one teacher, or €15.20 a month if you pay yearly. It includes every feature and you can try it free for 14 days without a card.

Teams, for small academies and teams of teachers, is paid per teacher: €19 a month per teacher, €17 from the 4th and €15 from the 16th. And you never pay per student, so adding Laura doesn't raise your fee.

Prices exclude VAT. And you can cancel any time: no lock-in.

How do your students pay you?

Your students pay you by card or Bizum through Stripe. SmartCookie keeps 0.6% of each online payment, Stripe's fee is separate and payments you mark by hand cost nothing.

Turn lessons taught, a pack or the monthly fee into a payment request and send it. That way you stop chasing transfers at the end of the month (and that little voice saying "she'll pay me eventually").

Laura pays by transfer and Marcos in cash? Perfect: mark them as paid by hand, at no cost, and their records stay up to date.

Questions about Bizum? Its limits, its fees and what the tax authorities see are in our guide on getting paid by Bizum.

What doesn't SmartCookie do?

SmartCookie doesn't find you new students and doesn't issue legal invoices. It organizes the students you already have.

Who is behind SmartCookie?

SmartCookie is built by Martina Monreal, a language teacher since 2016, and Óscar Pulido, a software developer, who launched it together in 2025.

Yours truly spent years with lessons in one app, payments in another and notes in a notebook that was frankly terrifying. So we built the app I dreamed of as a teacher: Óscar turns the ideas I give him into code, and then I make sure (by asking teachers like you) that the tool really works for every teacher, on any given Tuesday at 5:58pm, with Laura about to join class.
