What is PhantomThread?

A live iMessage and WhatsApp simulator that makes your phone look busy. Real bubbles, typing indicators, tapbacks, read receipts, and the actual sounds. Turn on Auto mode and texts come in on their own.

Waiting at a bar and want your phone going off? Want to look busy at the office? That's what this is for. Not a fake screenshot generator. It runs live, while people are watching. Also works as a film prop, skit tool, UI demo, or notification sound tester.

Frequently asked questions

What would I use this for?

Mostly for looking busy. Prop your phone up, turn on Auto mode, and let it buzz while you wait for someone or get through a slow afternoon. It's also handy as a film prop, a skit tool, a UI demo, or just a way to test notification sounds.

Is this a fake text message generator?

Not really. Those make a screenshot you show someone later. PhantomThread runs live: the sounds, the typing bubbles, texts coming in on their own while people are watching. You can export an image if you want one, but that's not what it's built for.

Is PhantomThread free?

Yes, completely. No account, no install, no ads. If you like it, there's a tip jar in the corner.

Are my conversations uploaded anywhere?

No. Everything runs in your browser. Your personas and settings are saved in local storage on your device and never leave it.

Can I create my own contacts and replies?

Yes. Open the persona editor and set the contact's name, avatar, and the replies they send back. You can export personas as JSON and import them later or share them.

Can I use my own sounds?

Yes. Go to Settings > Sounds, then click a row or drop an audio file on it to swap out the send, receive, or notification sound.

Which messaging platforms are supported?

iMessage and WhatsApp right now, each with its own bubbles, colors, and chrome in light and dark mode. Switch between them in the Simulator panel. More are coming.

Can I save a conversation as an image?

Yes. Hit Export (or press E) and it downloads the current conversation as a PNG in whichever platform you have selected.
