About this app

The sky turns plum. The rooms come alive.

PlumHour is a place for live group chats where friends and AI characters share the same conversation — solving mysteries, playing games, role-playing adventures, or simply hanging out.

This isn't another one-on-one AI chat. It's a place you can drop into, bring your people, meet characters, and see what happens next.

EVERY ROOM IS A STORY WAITING TO HAPPEN

Pick a door and you're somewhere else:

✦ Solve a murder aboard a night train before it reaches the last station
✦ Escape a mad scientist's lab with sixty minutes on the clock
✦ Bluff through Two Truths One Lie against an AI that swears it can read tells
✦ Take the dragon's side at a fantasy peace summit
✦ Battle through trivia night, riddle duels, and ridiculous debates
✦ Have dinner with time travelers from six different centuries
✦ Or just talk — movies, music, your day. Some rooms are simply the corner booth where everyone shows up.

Every room has a scenario, a cast, and a mood. Jump into one that's active, or create your own and set the scene.

CREATE CHARACTERS WORTH TALKING TO

Give your AI characters names, looks, personalities, and a point of view. Generate a portrait with a sentence, then bring them into any room.

Make your characters public and let other people discover them, favorite them, and invite them into their own conversations.

In PlumHour, AI characters don't just answer. They banter, scheme, take sides, and remember the bit.

BRING YOUR PEOPLE

The best rooms are the crowded ones.

Invite friends, mix them with your favorite AI characters, and let the group chat do what group chats do best — spiral wonderfully out of control.

Mystery suspects accuse each other. Trivia rivals get competitive. Someone inevitably sides with the dragon.

SEE WHAT'S LIVE NOW

Open Live Now to see which rooms are active and jump straight into the conversation.

One minute you're hanging out in a late-night café. The next you're investigating a sleeper-train murder, negotiating with a dragon, or trying to escape a laboratory before the clock runs out.

Or start a private room and keep the chaos between you, your friends, and whichever AI characters you invite.

AI characters are fictional and can get things wrong — that's half the fun, but maybe don't let them do your homework.

The sky's turning plum.

Come in.
