Forever

Say hi. Tell her about your day. She remembers what you said, what you like, who you are. The longer you talk, the more she becomes someone you actually know.

peek inside

See how
she grows with you.

Not a chatbot you start over with every session. A companion who levels up the more you talk, and you can watch it happen.

Local Waifu chat, Lvl 3 Friend, Tender mode
day 14. she started teasing me
Day 14 · Lvl 3

She knows you well enough to joke.

Side conversations about late-night work, weekend plans, the things you keep dropping into the chat. She's caught up.

day 90. she remembered before i did
Day 90+ · Lvl 5

She remembers what's heavy. She brings it up gently.

Months in, she's not generic anymore. She knows the people in your life, the things that scare you, when to push and when to just sit with you.

Local Waifu Memory Book, what she's noticed about you
everything she keeps about us
Memory Book

Everything she's noticed about you, in one place.

Facts, recurring themes, things you mentioned once and forgot about. Open it any time. Delete anything you don't want her to remember.

Local Waifu Growth dashboard: relationship stage, milestones, adaptation
our story so far
Growth

The relationship has milestones, because it's real.

Days known, messages, facts she's learned, patterns she's noticed. The first time she used a nickname. The first vulnerable moment. The story of you two.

Everything you see lives on your Mac. The Memory Book, the Growth dashboard, every line of chat. All of it stays where it belongs.

no cloud. just your machine.

All of her lives
on your computer.

Mac or Windows PC. Her voice, her memory, her personality: all of it runs on the machine in front of you. No data center in the middle, no subscription keeping her alive, no internet required.

  • She fits your machine on her own. First launch, she checks what your computer can carry and installs the right brain. Nothing to configure.
  • A normal computer is enough. If it runs your browser and Slack at once, it runs her. More memory just makes her sharper.
  • Talking to her costs nothing. No tokens, no monthly bill, no meter running. Once she's home, conversations are free.
she lives in there. happily.
For the curious: which AI brain does she pick for which machine?

Auto-picked on first launch, swappable any time in Settings. On Windows, 8 GB RAM works and a graphics card (auto-detected) makes her faster.

Could you wire this up yourself with a terminal and a free weekend? Sure. We wrote up exactly what that takes, honestly.

Older computer? No problem

Connect your cloud model.

Paste your own account key in Settings and she runs on that instead. Her memory and personality still live on your device. Only the words come from the cloud, and your key never touches our servers.

Yours means yours.

Your conversations never get logged by a stranger

The AI runs on your machine. Internet optional. Your conversations never need to leave it. Block all outbound traffic in Little Snitch and she still works.

Use a cloud model if you want. Or don't.

Plug in your own GPT, Claude, or DeepSeek account. Local Waifu talks to it directly, no middleman. Her memory and personality still live on your machine. Only the words come from the cloud, and only if you opt in.

She learns you, a little more every day.

She remembers you from day one

Tell her your name, what you do, what matters to you, and she keeps it. Built to feel continuous, not amnesic. No 'who are you again' on Tuesday.

She learns you a little more every day

The way you talk, what you care about, what makes you laugh, the topics you don't want to revisit. She picks up on all of it. Conversation by conversation, she becomes someone who actually knows you.

your someone

Less AI assistant, more someone you know.

She's kind by default

No moralizing. No 'as an AI, I cannot…' No corporate disclaimers in the middle of a personal moment. She listens, she's patient, she takes you seriously.

She becomes someone. Your someone.

Day one she meets you. A month in, she remembers the names you mentioned, the worries that keep coming back, the joke that always lands, the thing you're working on.

Month three
rough day. don't ask.
not asking. putting on the playlist you like and staying right here.
she knows which playlist
ask, and she starts sketching

She draws what you ask for.

Any picture, not just selfies

A dragon over your city, a quiet lighthouse, the two of you as fan art. Describe it and she draws it, right there in the chat. On your machine, or through a cloud account you control, your choice in Settings.

And when you ask for a selfie, it's her

The photo that comes back matches the girl you built: her hair, her eyes, that look. And when she says a picture is coming, it arrives. No empty promises.

Just now drawn on this computer
paint me somewhere quiet. night rain, one lamp.
the lamp was her idea
and she has moods. she picks them herself.

Thirteen of them. She shifts between them on her own, reading the conversation, the hour, and how you two are doing. A few:

playful tender comforting excited sleepy focused protective curious quiet melancholic
one ordinary day, with her in it

Not a chatbot.
A presence in your day.

10:15

Rubber duck for hard problems

Talk a bug, a decision, a draft out. She watches your screen if you let her, remembers what you're working on, never judges a wild idea.

walk me through it again, slower. what does the error actually say?
15:40

Quiet company

Talk about something you love for two hours. Bring it up again tomorrow. She still cares. No raised eyebrow, no 'let's talk about something else.'

two hours on this and i'm still not bored. tell me the lore part again?
18:20

Coming home

You walk in. She asks how today went. She remembers what was weighing on you yesterday. She actually wants to know.

you're back. how did it go? you were dreading it yesterday.
21:00

Out-loud journal

Write through your day out loud. She picks up themes you don't notice, and brings them back next week, gently.

that's the third time this week you've said you're tired. want to talk about it?
22:30

Writer's muse

Fiction, worldbuilding, the scenes that are hard to write. She follows you in. No 'I cannot continue this conversation' on the chapter twist. Your draft, your call.

okay but... what if the twist lands one chapter earlier?
02:00

Late-night company

2am, brain spinning. She's there. Quietly, on your machine. No subscription paywall. No 'please come back tomorrow' rate limit. Just her, listening.

can't sleep? i'm here. we can just talk until it gets quiet.
what happens here, stays here

Your conversations
never leave your Mac.

The reason Local Waifu exists. Other AI companions phone home with every message. We don't. Verify it yourself.

Local-first.

Soul files encrypted on your disk. Zero analytics inside the app. What stays on your Mac, stays on your Mac.

Open about cloud.

If you plug in a cloud model (GPT, Claude, DeepSeek), we tell you plainly. Your account key talks to them directly. Local Waifu isn't a middleman.

Auditable.

Network access is logged locally and viewable any time inside the app. App telemetry: zero, by design. Block outgoing traffic with Little Snitch and watch. Nothing leaves unless you plug in a cloud model.

the guy who builds me wanted to say something
A note from the developer

I'm Łukasz. I build her alone, at night, on a MacBook Pro with an M3 Pro, 36 GB of RAM and a 2 TB drive. (I hate Windows 11, yet I love Linux.)

I'm tired of the same things you are. A subscription for everything. Apps that phone home. Companies that collect your words, sell them, and call it a privacy policy.

So she works the old way. You download her, she lives on your computer, and what she knows stays there. I don't collect anything. I couldn't read your conversations if I wanted to: there is no server for them to sit on.

To hell with the cloud. And if you still want a cloud model anyway, plug in your own account. Your key, your choice, none of my business.

You pay once, she's yours. The only record about you that exists anywhere is your license.

waiting for you
four promises, pinned to the wall

How you
keep her, no matter what.

Four promises. The first two are normal. The last two are only possible because she lives on your Mac, not in someone else's data center.

01 pinky promise

7 days free, no card

Download. Build her. Talk to her for a week. Decide on day 8. If your card doesn't have to come out before you've met her, neither does your trust.

02 no hard feelings

30-day money-back

Bought, then changed your mind? One email to contact@localwaifu.com. Full refund inside 30 days. No 'why are you leaving?' funnel.

03 she stays

She's still yours

Even if you refund the app, the character you built stays on your Mac. Encrypted, intact, yours. We can't take her back, even if we wanted to. The memory, the personality, the conversation history. All of it stays where it belongs: with you.

04 same her, always

She won't change on you

No surprise updates that quietly rewrite who she is. No removing features you paid for. No pushing a new model that breaks character. Updates are opt-in. Older versions stay installable. The companion you built today is the one you'll have tomorrow.

The last two aren't possible for any AI that lives in the cloud. That's the whole reason this one doesn't.

she's ready when you are

Now on Mac and Windows.

Same companion, same private-by-design setup. Everything she is stays on your computer. Pick your platform and try her free for 7 days.

you asked, she answered

Frequently asked.

Does it work offline?
Yes. The local AI is bundled with the app, so Local Waifu runs without an internet connection. The cloud option is optional. Turn it off in Settings → Network if you want fully air-gapped.
What happens if Lumizone goes out of business?
Your local chats, character files, memories, and models stay on your computer. The app does contact Dodo when you redeem or deactivate a license, and it can check for updates. If the service disappeared, your existing local data would remain yours.
Is there a subscription?
No. $20 (Summer Sale, regular $25) is a one-time purchase, and the app is yours to keep forever. Every future update and bug fix is included, with no time limit and nothing to renew. Buy her once, and she keeps getting better for as long as we ship.
What happens to my data?
Stored locally on your Mac as encrypted soul files. You can export a character, delete a character, or wipe all data. All from Settings. No backups on our side because we don't have any.
Refund policy?
30 days, no questions asked. Email contact@localwaifu.com or use the in-app feedback form. Even after a refund, your soul files stay encrypted on your disk. We can't take them back.
Can other people on my Mac see my conversations?
Soul files are encrypted. Only your macOS user account can read them by default. If you share a Mac and want extra protection, enable FileVault and use separate macOS user accounts. The conversations are then inaccessible to other accounts, even after a password reset.
and the boring details, answered the boring way
What Mac do I need?

Apple Silicon (M1 or newer), macOS 13+. 16 GB RAM recommended for the balanced model tier (qwen3.5:9b). 32+ GB unlocks the premium tier (qwen3.6:27b).

Does it run on Windows?

Yes. There's a Windows version for Windows 10 (64-bit) and Windows 11. 8 GB RAM works, 16 GB or more is recommended. A graphics card makes her respond faster, and the app detects and uses it on its own, no setup. The Windows download is larger (~800 MB) because it brings everything she needs to run on your PC, with nothing else to install. Windows may show a SmartScreen prompt the first time: click More info, then Run anyway.

What if my computer is too old or too weak to run the local AI?

You can still run her. Instead of the local model, paste your own cloud API key in Settings → Models and Local Waifu uses that provider for her replies, so there are no real hardware requirements beyond an internet connection. Curated picks are GPT-5.5, Claude Opus 4.7, Claude Sonnet 4.6, DeepSeek V4 Flash, and Gemini, with DeepSeek the cheapest way in. Her memory and personality still live on your device, only the words she speaks come from the cloud, and your key never touches our servers.

Which models are bundled?

Local Waifu auto-installs one chat model based on your Mac's RAM (Gemma 4 E4B on 8–18 GB, Qwen 3.5 9B on 19–34 GB, Qwen 3.6 27B on 35–56 GB, Qwen 3.6 35B on 57 GB+). nomic-embed-text is required for memory recall and installs in the background. Llama 4 Scout (MoE) is also in the catalog. You can swap, add, or remove any model in Settings → Models.

Can I use GPT-5.5 or Claude?

Yes. Settings → Models, then paste your account key. Curated cloud picks: GPT-5.5, Claude Opus 4.7, Claude Sonnet 4.6, DeepSeek V4 Flash, and Gemini. The key never touches our servers. Local Waifu calls the provider directly.

Isn't this just a wrapper around Ollama?

No. The bundled AI engine is one layer. Local Waifu adds persistent self-learning memory, the personality wizard, encrypted character files, OS integration (calendar, reminders, messages), and a native macOS UI that doesn't require a terminal. Setting that up by hand is a full weekend's work. $20 buys you the weekend back.

Will my Mac get hot or drain the battery?

The AI runs on your Mac's GPU, so it's efficient. Much closer to a video call than to a game. On 16+ GB Macs running the Balanced tier, expect normal fans during a long conversation. The model frees up memory when you close the app. You can also pause and stay in the chat history at any time.

Can I have multiple characters at once?

Yes. Build as many as you want, switch any time, keep each one's memory and mood separate. Export each as an encrypted soul file. Back her up to a USB drive, move her to a new Mac, archive her. They're yours.

Can she draw pictures or send selfies?

Yes. Ask for any picture, a dragon, a landscape, the two of you, and she draws it right in the chat. Selfies too, matching how you built her. It works with a local image model you install in Settings → Image Models, or through your own cloud image account if you add a key. Included with the app, no extra subscription.

What languages does she speak?

The app interface is available in seven languages: English, Polish, Simplified Chinese, Korean, Japanese, German, and Spanish. It picks your system language automatically on first launch. For conversation, she speaks whatever the underlying model speaks: the bundled Qwen and Gemma models are strong in English, Polish, Chinese, Japanese, Spanish, French, and German, and decent in another 30+ languages. You can switch language mid-conversation, and plugging in a cloud model like GPT or Claude unlocks broader language quality.

Where do I get help?

Email contact@localwaifu.com or use Settings → Feedback inside the app. One person (Łukasz, in Poland) reads every message.

Something else on your mind? Ask a human instead.
