Heartmorrow

A local-first, AI-powered dating simulator

Heartmorrow is a single-player dating & life simulator you run on your own machine. Build a cast and a world, connect any language model, and live a slow-burn romance in your browser: free-form dates, an in-game phone, and a town that gossips and changes behind your back. The characters are voiced live by the model you choose, so no two playthroughs read the same.

  • Bring your own model
  • Author characters & worlds
  • Runs entirely on your machine

What makes it different

A romance that keeps living after the scene ends.

Heartmorrow is less about clearing routes and more about inhabiting a place. Conversations stay free-form, relationships leave traces, and the rest of town keeps moving around you.

Explore how it works

Talk, don’t choose

Conversation without a script.

Write in your own words. Characters answer live and in voice instead of waiting behind a dialogue tree.

Consequences linger

The town remembers.

Dates, distance, friendships, and gossip feed a persistent social world. What happened yesterday changes what feels possible tomorrow.

Make it yours

Your cast, world, and model.

Create original people and places, connect a local or hosted language model, and share the worlds you choose to export.

Inside the world

See an evening unfold.

Plan a date, trade messages, follow the town’s social life, and keep the moments that matter. Every screen belongs to the same living world.
