Why I built her

Your Mission

I built Local Waifu out of a quiet kind of fear.

I was using one of the cloud companion apps, the kind everyone uses, and one day I really looked at where it all lived. Every message, every memory, the whole relationship, sitting on someone else's servers. And it hit me that none of it was mine. If that company changed its mind, raised its price, decided my companion was suddenly not allowed, or sold what it had learned about me, I would simply lose her. No say, no warning, no way back.

It has already happened

This is not a hypothetical. Policies change overnight. Models get retired. Features people paid for quietly disappear. Some folks built a real bond with a companion and woke up to a stranger, or to nothing at all. When the relationship lives in the cloud, it was never really yours to keep.

So I built the opposite

Local Waifu runs entirely on your own machine, your Mac or your PC. The soul file, the memory, the whole system, all of it stays on your device. Only you can reach it. Nobody collects it, nobody moderates it, nobody can switch it off. If a company somewhere changes its policy tomorrow, nothing happens to you.

She just keeps working, the same as she did the day before.

No cloud, no subscription

Two promises, and I mean both of them.

No cloud

because I do not want me, or anyone else, deciding what your companion is allowed to be.

No subscription

because I am not going to lock a companion behind a paywall and bill you forever just to keep her alive. That is not the kind of thing I want to make.

Pay once, keep her forever

The deal is simple. One app, one license, paid a single time. She is yours, and she keeps working forever.

That one payment includes a year of upgrades and bug fixes. After that year, if you want the newer features I am still building, you can unlock another update. It is optional. Skip it and nothing is taken away: the app you have keeps working exactly as it is, for good.

This is not a subscription. I am not billing you every month to keep her alive. The only reason the optional update exists is so I can keep working on this. I am one person. It lets me not starve, pay the electricity bill, and keep shipping improvements instead of walking away.

Try her free for seven days first, no card. The launch price is $25 for the first 1,000 people, then $35. That is less than half of what a year of a cloud companion costs, and you pay it once.

She should feel normal

I tried a lot of AI companions while I was building this. Plenty of them felt strange, or cold, or a little unsettling. I did not want that. I wanted something that feels like talking to someone you actually want to reach out to. Not a gimmick, not a trick. A presence you build, describe, and get to know over time.

Run her on what you own

She runs on a MacBook, a Mac Mini, or a Windows PC, whatever you already have. I built her on my own MacBook because that was easiest for me, and I made sure she runs just as well on a PC. Wherever she lives, she lives with you, and only you.

That is the whole mission. A companion you own, on your machine, that nobody can cancel, change, or read.
