A quiet debut for a new kind of writing room

Proscenium

The modern workspace for musical creators.

Write, organize, and refine musicals with intelligent AI that enhances your creativity — not replaces it.

Made for the stage

A workspace that thinks in acts, not files.

Every tool here understands what a musical is — scenes, songs, characters, beats — so you can spend your energy where it belongs: on the work.

Script Workspace

One elegant editor for dialogue, lyrics, and stage directions.

Write in an editor that was designed for musicals from the first keystroke — with formatting that knows the difference between a character line, a stage direction, and a song, and gets out of your way while you write.

  • Auto-formatted characters, songs, and scenes
  • Distraction-free typography built for reading aloud
  • Export to industry-standard script formats
Act I — Scene 3
Interior. Empty theatre. Late night.
A single work light on stage. ELIAS enters, holding a bound score.
ELIAS I keep hearing it. In the walls, when everyone leaves.
MAREN Then it isn't the theatre haunting you. It's the song.
Song · "The Work Light" If the house is dark and the seats are bare,
still there's someone singing somewhere —
in the rafters, in the rope, in the air
Musical Timeline

See your story the way an audience will hear it.

Zoom out from the page and watch your musical unfold as a timeline — scenes, characters, songs, and dramatic beats laid alongside one another, so you can feel the pacing before you ever hear the overture.

  • Parallel tracks for characters, songs, and tension
  • Drag scenes to reshape the arc
  • Spot pacing gaps before your first read-through

AI Collaboration

A thoughtful collaborator, seated at the table with you.

Ask for a sharper couplet, a stronger beat, a redistribution of lines between duetting voices. The AI works alongside you — proposing, never deciding — so the creator's judgement always stays in the room.

  • Refine lyrics, dialogue, and pacing on demand
  • Rebalance lines between characters in a scene
  • Every suggestion is a diff you accept or reject

Maren's final line feels flat. Can we lift it without losing her quiet?
Try tightening it to a single image. What if she doesn't say she hears the song — she names the room it's in?

"Then it isn't the theatre haunting you. It's the song, and it's already learning your name."

Automatic Knowledge Base

The show remembers itself, so you don't have to.

As you write, Proscenium quietly builds an internal understanding of your characters, their relationships, the themes that recur, and the settings they move through — no forms to fill in, no wikis to maintain, just a story that grows more coherent with every page.

  • Characters, motifs, and settings tracked automatically
  • Relationships evolve as the story does
  • Ask the AI anything about your show — it already knows
