An operating system for your AIs.

Give them shared memory, files and a home for all the apps they build for you.

Works with

And other AIs that let you connect your own tools.

Inês and Théo sit on their cushions, each with their own phone. Above them, Par's pink brain holds the cards of the trip they share: a train, a map, a croissant and a present. Dotted lines run from each of them up to the same brain and back down: her phone shows her packing list, his shows his train plan.
Inês and Théo share one Par for their trip. She gets her packing list. He gets his train plan.
Inês sits on a cushion with her phone. Her French flashcards show her own week: a coffee, a train, a bike. Par's pink brain deals one more card, the coffee, onto her screen.

Made for you.

“Quiz me in French on my own week.”

Inês is learning French for her trip. Her phone quizzes her on her own week.

Apps made from your life

One Par, every AI

Claude remembers Claude. Gemini remembers Gemini.

Inês sits on her cushion with her phone. Around her, four AIs at once, each with its own sparkle: one on her laptop, one on her phone, one on her tablet and one working by itself in the cloud. Dotted lines run from all four to Par's pink brain in the middle, which holds their cards, so a file, a piece of research or a date that one of them finds reaches the others.

Inês tells Claude on her phone, and Gemini on her tablet and Grok on her laptop already know. All her AIs share one Par. None of them starts from zero.

Par, page by page

One Par under your day, your people and your work.

01 Your day and your life

Morning. Omar, coffee in one hand, reads his paper on his phone; one row is yellow, the thing that needs him today. Par, the pink brain, holds up his record and his calendar.

Par Daily

Every morning, your AI writes your paper.

Your news, your day, your look.

Crayon drawing: Leila runs in the morning by the canal, her phone on her arm. Beside her, her habits app shows the week as seven columns, with three green dots for three runs.

Par Health

Health apps that know your life.

Leila runs every morning. On her travel day, all three of her health apps already know.

A crayon drawing: at a bakery counter in Lyon, Inês reads her order in French from her phone while the baker hands her a bag of croissants, and the whole queue behind her waits patiently.

Par Languages

Every app teaches French. Yours teaches your trip.

Inês goes to Lyon for Christmas. Her first lesson is the bakery she'll walk into on Dec 23.

Omar taps the yellow button on the first card of his feed, on his phone; the same three cards sit side by side on his laptop. The Par brain carries a green check along a dotted line to Mei, who sees it on her laptop.

Par Feed

A feed made of your life. Not someone else's algorithm.

Every card does something, right there.

Drawing: Grandma Lurdes holds her old recipe notebook open, Nora takes a photo of the page with her phone, and the pink Par brain reads the page through a magnifying glass and finds a corn cake in it.

Par Files

Drop it in. Find it by what's in it.

Put a photo or a PDF in Par. Your AI reads it, so later you find it by what's inside.

02 With your people

Drawing: a custom scooter with a tall windscreen and a pink fur seat. Yui presses a heart sticker onto the tablet on the handlebars, which shows the club's route map; Mr. Okada rolls a lint roller over the seat, and the Par brain hangs from the mirror like one of the plush charms.

Par Tribes

One Par. Every tribe.

Same Par underneath. A different app on top.

Drawing: four friends on a sofa race tiny critters on the TV, each with their own phone as the controller; Leo leans in and talks to the TV, two dogs watch from the rug, and the Par brain sits on top of the TV.

Par Gaming

Ask for a game. Play it tonight with your friends.

They talk while they play, and the scores stay.

A drawing: Juno asks her AI for her page on her phone; the Par brain holds up the finished page, and it is on her laptop and on the phones of Leo and Mira.

Par Sites

Your site, made by asking. Changed with a message.

Use it as your link in bio.

03 Your work

Mei's usual apps sit on four screens: a task list, a phone, a document and a chart. Par gathers them, and on her laptop she sees them all together on one screen.

Your tools

The apps you already use. Your way.

Your team's tools on one screen, made the way you work.

A drawing: Inês asks her AI on her laptop for an app for Saturday's padel, and it pops up on Nora's, Leo's and Mira's phones; Leo taps to join a court.

Par Apps

Apps used to start empty. Yours start with your life in them.

Your app starts with what Par already knows, and it changes the moment you ask.

A reporter speaks into her phone beside a barrier at a small bridge. The Par brain carries the update along a dotted line to a man on a bench, who sees it arrive on his phone.

Par Reporter

Say what you see. Your readers see it live.

Nadia reports from a bridge. She says one new fact, and her whole story updates.

04 Everywhere, and how

Mei holds her phone up next to her laptop; both show the same Par app, with the same row checked, because the phone and the laptop read the same Par.

Par on every device

The same Par, on every screen.

What you start on one screen is waiting on the next.

Grandma Lurdes tastes soup from three small bowls and picks one, while Nora holds her phone. The Par brain opens a little envelope pinned to Sunday on a calendar, and a green check mark pops out.

Predictions

Par predicts what happens next. Then it checks.

A deadline, a habit, a decision: Par says how sure it is, checks when the day comes, and gets better.

A mother and her daughter walk a dotted path toward a big yellow star, with the pink Par brain beside them holding a lantern.

Your north star

Par understands your goals from what it stores.

Ask your AI “Am I still on track?” It shows where the week matched what matters, where it drifted, and the progress you missed.

A man carries the Par brain in a box from a laptop with one AI to a laptop with another.

How Par works

Change the AI. Keep your Par.

Switch to another AI, and everything Par knows about you comes along.

Lia sits at her laptop, where a small yellow star stands for her AI. The Par brain floats toward it with a recipe card and an alarm clock under one arm and, in both hands, a little bookshelf whose books are linked by dotted lines, a new yellow book sliding in.

Knowledge

Give your AI everything you know.

Everything you know about a subject, organized and current, in every AI you use.

What you get

Every app you ask for comes with all of this.

  • It already knows youIt's made from what you've told your AI. No forms to fill in.

  • Use it togetherFamily and friends, each on their own phone. Everyone sees every change at once.

  • Your apps work togetherAdd a flight in one, and your packing list already knows.

  • Any AI you likeMake it with Claude, change it with Gemini. Your apps stay the same.

  • A real app you keepOn your phone and your computer. Still there tomorrow.

  • Nothing to set upJust ask. No code, nothing to install, nothing to keep running.

These were other people's. What will yours be?

Connect the AI you already use, and ask it for one app you need this week.
