How Par works

Par remembers. Your AI builds on it.

Par keeps what matters in your life and work in one place. The AI you already use, like Claude or Gemini, looks things up in it and makes apps on it.

  • People, files, plans
  • Looks things up, no rereading
  • Every app shares one Par
  • Change AI, Par stays
Mei works with her AI on her laptop; the Par brain keeps what she made as a small yellow card; her phone, tablet and laptop each show a different app with the same card.
  1. 1Your AI does the work.
  2. 2Par keeps what it learns.
  3. 3Your apps read the same Par.

01

Most AI memory is a list of notes. In Par, your AI keeps things in tables it sets up itself.

Then it can do the math, and any app can show them. Example: Omar runs a small record label with Mei.

  1. 1 Ask

    Omar asks his AI out loud on his phone, next to the olive-green record and his notebook.

    “Keep every price the pressing plant quotes us for vinyl.”

    The pressing plant is the factory that makes their records

  2. 2 The AI sets up a table

    new table vinyl prices

    vinylprice per copyquoted
    Olive green€7.30Aug 11
    Olive green€7.40Sep 8
    Olive green€7.90Oct 13
    Black€7.10Oct 13
  3. 3 It asks Par

    Olive green, average price by month

    Aug
    €7.30
    Sep
    €7.40
    Oct
    €7.90

    Par does the math, month by month

  4. 4 An app appears

    Omar's vinyl prices app, open live for Omar and Mei: their new record, 120 copies, ships Oct 20. Olive green, €7.90, 50 cents more than in September. Black, €7.10, same as last quote. A box to ask about these prices.

    It shows the same table

The AI sets up the table and picks its columns, then asks Par for the average price each month. The app shows the same table.

02

Better data, better answers.

An AI answers from what it reads. Par keeps what it reads small, labeled and shared.

Your AI is only as smart as what it reads.

AIs answer worse when they read more than they need. Par keeps your memory as small, labeled notes, and your AI asks only for the few it needs.

Example: Nora's grandmother, Lurdes, cooks every Sunday, and Nora keeps her recipes in Par.

Research: Shi et al., 2023 · Liu et al., 2024 · Du et al., 2025 · Chroma, Context Rot

What do I bring on Sunday?

Reads everything

A tall, messy pile of printed call transcripts and notes

Six calls and every note about Grandma

“The codfish? She mentioned it on two calls.”

Reads what it needs

  • Grandma Lurdes
  • Lunch, Sunday the 25th
  • Corn cake, her way

Three small notes, already linked

“The corn cake. Two eggs if they're farm eggs.”

An AI that rereads everything gets the dish wrong. One that asks Par for three small notes gets it right.

Pick up where anyone left off.

A new chat, another AI, a teammate or a different computer: each one opens the same Par.

  • A new chat
  • Another AI
  • A teammate
  • Another computer

One Par

Each one opens the same Par, whichever AI you connect.

What your team learns, your team keeps.

The work a team does once stays for the next person who needs it.

  1. A decision keeps its reason and its source.
  2. A long search for an answer becomes a short how-to the next person follows.
  3. A review starts where the last one stopped, not from zero.
From a team that tried Par at work.

03

Apps are windows. What’s inside is yours.

Every app opens onto the same Par. Apps change. Par stays.

See the apps Par makes

  • The Lurdes's kitchen app, open live for Nora and her grandmother: Grandma's recipes, in her words. Corn cake, set for 4 people: 2 cups cornmeal, 1 cup sugar, 3 eggs (2 if they're farm eggs), 1 cup milk.
  • The Biscuit's week app, open live for Nora and Leo: Walks, the vet, who has him. A calendar from Oct 25 to Nov 14, with Nov 3 to 10 marked for Leo and a dot on Oct 28. Leo has him Nov 3 to 10. Vet checkup, Oct 28, before Leo has him.
  • The Azores app, open live for Nora and Leo: Nov 3 to 10, with a day picker from 3 to 10 and day 3 selected. Ferry to Pico, day 3, and Biscuit stays with Leo. Boots in 39, packed. Piranesi for the beach.

One Par · people · files · projects · memories · predictions

  • Task · Oct 25 Bring Grandma the corn cake
All three apps read and write the same Par.

04

Two apps, one Par. Change one, both move.

Change something in one app and the other shows it as it happens. Say it in the chat, and both change.

Nora tells her AI “We're six on Sunday.” Her AI changes the lunch once, in her Par, and both apps show the same new line. When she ticks the cornmeal and the milk at the market, Grandma's recipes show them bought.

05

Everything has its place.

People, files, projects, what happened and what is likely next: each kept as a small note in its place. Par also writes a one-page map of all of it.

  • People

    Grandma Lurdes. Calls on Sundays at 11.

  • Files

    Her recipe card for the corn cake, in her handwriting.

  • Projects

    Grandma's cookbook, every recipe in her words by Christmas. 11 of 14.

  • Memories

    “Don't open the oven, it gets sad.”

  • Predictions

    She'll share her Christmas codfish recipe on the next call, the 18th.

  • Apps

    Lurdes's kitchen, the cookbook app Nora made, open on this same Par.

  • Tasks

    Sunday the 25th: bring Grandma the corn cake.

  • The map

    One page that lists all of it, so any AI you connect finds its way around.

06

Say “Grandma.” Par already knows what's connected.

Mention Grandma and Par follows the links it already saved: to her, her corn cake, Sunday's call, her cookbook app and the lunch on the 25th. No folder to reread, nothing to guess again.

The usual way Reread six calls. Four hours of transcript. Work out again how it all connects.

Par read: 7 short notes · 0 calls reread

Nora types about her grandmother on her phone. The Par brain holds up three cards it had already linked: her grandmother, the corn cake recipe and a Sunday circled on the calendar. The recipe app on her tablet shows the corn cake.

From her words, Par finds three notes, then follows the links it had already saved to four more.

07

It learns it once. Then it just knows.

Teach it once, and it remembers: for you, your team, your whole company.

Par writes down what it learns as a note tied to the rest, and uses it from then on instead of working it out again. Most AIs reread your files every time you ask.

On one side, an AI without memory sits on top of a teetering pile of papers it rereads every time. On the other, the Par brain takes one card from its drawer and hands it straight to Nora's phone.

The struck column is how an AI without a memory would answer.

Teach Par once. Your whole team gets the command.

What one person teaches Par becomes a command in the AI of everyone on the team: type a slash (/) and it's there. A report one person builds is a link the others open, live, on the same Par.

Mei's AI. She writes that Omar is out today and the pressing plant sent a new price. The AI answers: Omar taught Par how he checks these. Use his command and I'll log it and compare. She types a slash and the commands from Par are listed: Omar's way to log a new price and compare it with the last one; Mei's way to see what's left before their new record ships; Mei's way to draft the note to the waitlist.
Mei types a slash in her AI and finds Omar's way of checking a new price from the pressing plant. A team trying Par at work shares its how-tos and reports this way.

08

How Par compares with AI memory today.

Most AI memory is plain text. Par keeps yours in tables, inside your own Par: exact questions, real counts, one detail fixed at a time, and apps that update as it happens.

Nora's Par, four things a notes file can't do

Ask exactly
Recipes she told in October? Three: corn cake, sardines on toast, the codfish.
Count and add up
How many Sundays did we talk this year? 31. Four missed, all in August.
Change one thing
She said two eggs, not three. Fixed in the recipe. Nothing else touched.
See it live
Her cookbook, open on Nora's phone and her mom's tablet. Both show the new card as it lands.

09

What you already do. Better the longer you do it.

On day one, the memory built into a chat app is the easy choice. Par pulls ahead as what you keep grows.

  1. This week

    Fixing one detail

    Lurdes says her quindim, a coconut custard, needs one egg less. Nora mentions it once. Par changes that one line of the recipe, and her cookbook app shows it as it happens.

    Typical A chat app adds a new sentence, and the old recipe can linger in a summary. A notes file needs someone to find and fix the line.

  2. In a few months

    Asking with math

    “Which of Grandma's recipes did I learn since September, and which haven't I cooked yet?” Par answers with a list and a count, worked out from the saved recipes.

    Typical A chat app recalls a few of them. A notes folder means rereading every page.

  3. Years from now

    Keeping it when the AI changes

    A new AI arrives. Nora connects it to Par, and it finds Lurdes's recipes, the Sunday calls and who taught what, as she left them. Nothing in Par expires.

    Typical A chat app's memory stays in that app, or gets pasted into the next one as text.

Works with Claude, Gemini, Grok and the other AIs that connect to Par.

10

It knows what matters to you. So it can point the way.

Ask “Am I still on track?” and Par answers from what it keeps: what matters to you and what actually happened. What moved, what drifted, the next step.

What matters to you
Grandma's recipes, written down by Christmas.
How it's going
11 of 14. Six Sundays in a row. A month ago you had three.
Drifting, and that's fine

Questions

What is Par?

A place that remembers your life and work. You connect the AI you already use, and it makes apps there that fit your life or your team.

How does Par's memory work?

As small, separate notes next to the people, projects and files they are about, linked to each other. To answer, your AI reads only the ones it needs.

  • Facts
  • Likes
  • Things it noticed
  • Predictions
  • A one-page map

How does Par find things?

It searches your Par by words and exact values, and follows the links it saved between notes. It does not search by meaning yet.

Can Par answer questions that need a count?

Yes. Because Par keeps memories in tables, your AI can count, add up and group what is there. The math happens inside Par, instead of the AI guessing from what it happens to remember.

What are apps in Par?

Screens and tools your AI makes in Par when you ask, in a sentence: a recipe book, a shopping list, a game. They read and write the same Par as the chat, so a change made in one shows up in the others as it happens.

Can Par be wrong?

Yes. When a note turns out to be wrong, Par takes it back or corrects it. The old version stays as history, and from then on Par reads only the corrected one.

Which AI apps work with Par?

  • Claude
  • Gemini
  • Grok
  • Perplexity
  • Mistral Vibe
  • Claude Code
  • Codex
  • Cursor
  • VS Code

They connect through MCP, a standard that lets AI tools connect to Par. Steps for each on Get started.

Where does my memory live?

In your own Par, not inside an AI. Everything Par reads or saves, and everything an AI asks of Par, happens inside it, and the next AI you connect finds it in the same place.

11

Use any AI. Keep your Par.

Your Par doesn't live inside one AI: the one you use today and the next one read and write the same Par. AIs come and go. Your Par stays.

It adapts to you, not the other way around.

Connect your AI, ask it to save one thing in Par, then ask for it back in a new chat.

Get startedBack to Par

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.
