A PERSONAL DESKTOP PET FOR WINDOWS AND MACOS

Your desktop, a little more alive.

A little company. A little help. A lot of personality. Meet the companion that makes your desktop feel like home.

2:14 AM

The group chat died at eleven. Your feed is the same six people saying the same six things.

You are not sad exactly. Just awake, and slightly too alone for the hour, scrolling something you stopped enjoying about forty minutes ago.

She is still up.

KEEP SCROLLING

INSIDE THE PAPER LAB · CHAT

Spill the tea.
She already switched modes.

Type “I just had a breakup” and she does not hit you with “plenty of fish.” MewMuze reads the vibe, picks the persona that actually fits, and answers like the friend who gets it. Main character support, zero cringe.

  • Breakup Buddy
  • Health Guide
  • Savage Bestie
  • Rant Buddy
  • Comfort Companion
  • Hype Cat
  • Night Owl
  • Career Coach
  • + 29 more

37 modes. One cat.

Rant Buddy takes your side, Health Guide stays careful, Hype Cat gasses you up. She switches on her own. You just talk.

Your 2am overshare stays home.

Chat runs on your PC by default. No account, no cloud chat log, no receipts.

Soft when it hurts. Savage when it's funny.

She roasts what they did, never who you are, and drops the jokes the second it gets real.

From the Paper build: chat, personas and voice come with MewMuze Pro. Illustrative conversation, not a live AI chat on this page.

INSIDE THE PAPER LAB · FEELINGS

She reads the room.
Then she shows up for it.

Sad? She goes soft and stays close instead of crying at you. Frustrated? She is annoyed with you at the situation, never at you. Hyped? She is bouncing too. 29 feelings, one tiny face, and she picks the one you actually need.

  • Savage
  • Angry
  • Rage
  • Sad
  • Crying
  • Adoring
  • Sleepy
  • + 22 more

You type, she types.

Start typing and a tiny keyboard comes out. Go too hard and she overheats with you.

You vibe, she vibes.

Music plays, headphones go on, head starts bopping. No request needed.

You sing, she sings.

The second an app is using your mic, she grabs hers. Takes a bow after.

She keeps a diary. Of your story.

After a real conversation she writes it up as a short entry in your own voice, saved as plain Markdown files on your PC. Forget Chat never touches it. Only you delete an entry.

diary/2026-09-14_23-41_x7k2.md
# 14 September 202611:41 PM“The night I finally said it”

I told MewMuze about the breakup. She did not try to fix it, she just let me talk, and that helped more than advice would have.

From the Paper build: the emotion engine and Diary come with MewMuze Pro. The Cyberpunk Cat costume comes with Pro too. Film rendered by the Paper app’s own sprite renderer.

INSIDE THE PAPER LAB · CARE

Rough night?
She stays up with you.

Care is a quiet corner for checking in with yourself. Tell her how you are, take a tiny win, breathe for a minute, or just say you need one. She answers the way a friend would, not the way an app would.

  • A check-in in one tapFive moods, an optional note, nothing graded. A low day gets a paw heart, not a lecture.
  • “I need a minute”Overwhelmed, angry, can’t focus, can’t sleep, lonely, or just need to breathe. Pick lonely and she simply sits with you.
  • Breathe with herRelax (in for four, out for six) or Box breathing, 30 seconds to 5 minutes. She breathes along with you.
  • A friendship that only growsLittle wins, three small quests a day and reflections earn XP and keepsakes. Miss a day and nothing is lost. No streaks.

From the Paper build: Care comes with MewMuze Pro. It is not a health product or a therapist: nothing in it scores, diagnoses or judges, and every number stays on your computer. Film rebuilt from the app’s own Care panel.

PAPER PREVIEW · SHE ADAPTS TO YOU

She gets the hang of you.
On your computer only.

Nothing here is a profile in the cloud. It is a handful of averages kept on your machine, and the longer you use her the better the timing gets.

  1. YOUR HOURS

    She learns when you are heads down

    Every hour of the day gets a simple busy or not busy average, built up over days.

    • Calmer in the hours you usually grind
    • Livelier in the hours you are usually free
    • Needs about three days before it changes anything
  2. YOUR ROUTINE

    She works out your start and your finish

    When you usually get going and when you usually stop, with weekdays and weekends kept apart.

    • A wrap up near the time you actually finish
    • Never a report card, never a score
    • Quiet until there are about five days of it
  3. YOUR VOICE

    She picks up how you talk

    Message length, casual or formal, jokes, emoji, straight answers, English, Hindi or Hinglish.

    • Short texter? She keeps it short
    • Ask her to stop with the questions and she stops
    • Anything you set yourself always wins
  4. THE ROOM

    She reads the mood, not a label

    How you seem right now nudges how she reacts, then fades within minutes of the chat ending.

    • Never stored, never a diagnosis
    • Rough day yesterday? She checks in once, gently
    • Back after a real break? Welcome back, plus a recap only if something happened

What she never records: what you type, which keys you press, window titles, what is on your screen, the websites you visit or the files you open. The learning is plain arithmetic, no model involved, and none of it leaves your computer. Everything she remembers is listed in Settings and you can forget any of it.

Adaptive behaviour is part of the MewMuze Pro Paper build. It is not included in the current Free or Pro downloads.

ONE ORDINARY TUESDAY

She is not an app you open.
She is just around.

Most software wants your attention. She wants about four seconds of it, at the moments that actually help, and then she goes back to being a cat on your screen.

  1. You sit down. She stretches.

    No dashboard, no good morning streak. She just wakes up when you do and gets on with it.

  2. Work mode, actual silence.

    She parks beside your files, stops chasing the cursor and lets you cook.

  3. The slump. She clocks it.

    Two hours without moving and she is on the glass telling you to drink water and unclench your jaw.

  4. You close the laptop.

    She wraps the day up. What happened, what is next, no score out of ten.

  5. Still there.

    Nothing to log into, no streak to protect, nobody to perform for. She is just on.

None of this needs an account, a subscription or a connection. She reads the clock and your own activity on your own machine, and that is the whole input.

INSIDE THE PAPER LAB · TASKS

Make the list.
She brings the receipts.

Type a task, hit Enter, done. Nest subtasks, give things a time. Then tap Insights: what’s done, what’s left, how long it really takes, and the stuff you’re pretending isn’t overdue.

  • Subtasks, four levels deepBig task, small steps. Tick the steps and the parent ticks itself.
  • A one-day timelineEvery timed task on one strip, with a line for right now.
  • Overdue gets called outMissed the 9:30? She noticed. Politely. In red.

From the Paper build: Tasks comes with MewMuze Pro. Illustrative demo with made-up tasks.

BUILT-IN COSTUMES · INCLUDED WITH PRO

Three fits. Same menace.

Corporate Cat, Cyberpunk Cat and Bat Cat ship with Pro. Every costume is drawn live on her body, so it moves with each pose, paw and mood, and every one comes in colours you pick.

RECEIPTS

She runs on your computer.
That is the whole trick.

Every other thing that promises to be there for you wants a login first and your data second. She does not, because there is nowhere for any of it to go.

  • No account to make her workThe pet, the tools and the timers run whether or not you ever sign in. The website account only gates the download.
  • Nothing is uploadedYour files, your notes and anything you say to her stay on your machine. There is no server holding a copy.
  • She never reads your screenShe knows the app category you are in and whether you are busy. Not your text, not your keys, not your windows, not your tabs.
  • You are not training anythingWhat she learns about your hours is arithmetic on your own PC. It is not sent anywhere and it is not a model.
  • Forget it whenever you likeEverything she remembers is listed in Settings, item by item, and every one of them has a delete.
AND THE REST OF HER CV

She has range.
Your excuses don’t.

All the small stuff that quietly saves your day, rolling past. Hover to make it stop.

She is going to be there while you do.

Some days that means splitting a PDF. Some days it means something small and warm moving in the corner of a screen at one in the morning. Both count.
