The problem

You've got the game. Just not always when it counts.

In training everything works. In competition, pressure speeds up your thoughts, tightens you up and turns one mistake into a run of them.

  1. Before

    You think about everything that could go wrong.

  2. During

    One mistake is enough to pull you out of the game.

  3. After

    You replay the match for hours.

The problem isn't a lack of mental strength. The problem is never having trained it.

The vision

Mental is a skill.

And like every skill, it can be trained.

Our mission: to democratize mental training so every athlete can grow sustainably, protect their well-being, and rise to the occasion when it matters most.

The product

You talk. It coaches you.

It listens, guides you through it and remembers what matters to you. Nothing to type, nothing to set up.

01 / 05

Choose your goal

Prepare for a competition, work on a specific movement, or reset after a mistake.

02 / 05

Talk, it listens

The coach is an artificial intelligence. It knows your sport, your level and what you told it last time: the session shapes itself around you, not around a set program.

03 / 05

Let it guide you

It walks you through it out loud, step by step, and stops at the right moment. Nothing to read, nothing to set up.

04 / 05

What you take away

Most sessions end on one short cue, a phrase or a gesture, you take onto the court. You say what landed and what didn’t, and the next session starts from there.

05 / 05

Make it automatic

Sessions and cues are saved automatically so you can repeat what works.

Pre-launch screens. Content shown is illustrative; features and design may change before public release.

The method

Proven methods. Not pep talk.

Mentalizi builds on the techniques mental performance coaches use. Every protocol is designed to be short, repeatable and measurable.

Routines

Settle into the same routine before every competition.

Mental imagery

Rehearse a situation or a movement in your head before you do it.

Self-talk

Build simple cues that bring your attention back to the action.

The numbers, and their limits

Use cases

Train the moments that swing a match.

Before the competition

Build a stable routine so you stop improvising your mental state on the day.

After a mistake

Stop replaying the mistake, get your focus back and move on to the next play.

For a specific movement

Visualize your serve, your shot, your start or your next move before executing it.

Through periods of doubt

Get your footing back without hanging everything on your last result.

For coaches

Your team coach never reads your sessions.

Mentalizi doesn’t replace your team coach or your mental performance coach. It backs them up: you keep practicing between sessions, and you know what to talk about when you meet.

You decide

Your team coach sees your first name, your sport and your level: what you wrote yourself. Nothing else is shared.

Your sessions stay yours

What you say in your sessions isn’t shared, isn’t summarized, isn’t scored. That’s not a setting: it can’t be done.

You can raise your hand

One button, three topics: your head, your mental preparation, or something else. Your team coach sees that you want to talk and what about, never what you have to say. The rest, you tell them yourself.

Sport and esport

New arena. Same pressure.

We built it for both from day one: the mental pressure looks the same from one arena to the next, and so do the tools for holding it.

  • Before a penalty
  • After a double fault
  • Before a free throw
  • After conceding a goal
  • Before the starting gun

Ten situations, one mechanism: the pressure climbs, your attention narrows, you tighten up. That mechanism is what you train, not ten recipes to memorize.

Our boundaries

Mentalizi trains you. It replaces no one.

Three levels, and you move up when the one below stops being enough. We only cover the first, and we tell you when it’s time to move up.

  1. Level 1

    Mentalizi

    Whenever you need it, no appointment, and without having to admit anything’s wrong first. It’s the level that didn’t exist.

    This is where we are
  2. Level 2

    The mental performance coach

    A real person, ongoing support, an outside eye no software can replace. We come alongside: we help you keep the rhythm between sessions, and walk into the next one with more to work with.

  3. Level 3

    Healthcare professionals

    What goes beyond training is theirs, and theirs alone. Our job here is simple: notice it, stop, and point you the right way, fast.

In France, 3114 (suicide prevention) is free and answered around the clock.

Our approach in detail

Before you ask for access

    Small enough to read every reply and fix things before the next batch. That’s what’s moving the app forward right now.

FAQ

The questions we get asked.

How is it different from a general-purpose AI?

A general-purpose AI remembers what you tell it for the length of one conversation, and the longer the chat runs, the more the early details slip away. Mentalizi works the other way around: it gets better the more it gets to know you. After every session, your coach rewrites what it knows about you (your goal, what’s holding you back, what you decided to try, what worked and what didn’t land), and reads it back at the start of the next one. You never have to explain it all again. It all fits into a program: a four-week cycle, routines built from your own words, your mental map. A general-purpose AI answers a question; Mentalizi follows an athlete.

Does it replace a mental performance coach?

No. Mentalizi is there between sessions, or when you don’t have anyone, to get ready for a game or bounce back after a mistake. If you already work with a mental performance coach, Mentalizi comes alongside them. Anything beyond training is a matter for a healthcare professional: when that’s the case, the coach tells you and points you the right way.

Who sees what I say?

In the app, your journal and your sessions are visible to you alone. To answer you, the coach relies on OpenAI, our AI provider: your voice and your messages pass through it for the length of the conversation. No audio is stored; the transcript is kept for 90 days. If you join your team coach’s squad in the app, you choose what they see. They never see your conversations. You can download all your data, or erase it, from inside the app.

The details, in the privacy policy

How much does it cost?

Free during the beta. After that, a free Discovery plan with no card needed, then a subscription you can cancel from your phone whenever you like.

Which sports, which level?

Anyone who trains and wants to be ready on the day, from weekend players to elite athletes, in sport and in esport. The coach adapts to your sport and to what you already know about mental preparation.

Do I have to talk, or can I type?

Both. You talk to your coach like on a phone call, or you type when you can’t talk. It remembers one just as well as the other.
