FADE IN:
Write the script.
Invite the room.
Bring your own AI.
Stream is screenwriting in your browser: a page that formats itself, a board where every scene is a card, and a room where your collaborators — and the AI you choose — write beside you, live.
Free for 3 scripts. No card.
INT. THE PAGE — DAY
A page that formats itself.
Type in Fountain, the plain-text screenplay format, and Stream sets it in Courier as you go — scene headings, action, character cues, dialogue, transitions. Real page breaks, a live page count, a title page.
- Export a PDF to read, or Final Draft to hand on.
- Red pen for the rough parts: write in red, revise in black.
INT. THE BOARD — DAY
Every scene is a card.
Step back and the script becomes a board: acts, sequences, scenes. Colour them, name the colours, drag a card somewhere new — and the script moves with it. The cards are the script.
INT. THE WRITERS’ ROOM — NIGHT
Write together, live.
Invite a co-writer to edit, or a producer to read. Everyone’s caret, everyone’s name, on the same page at the same time — no versions to reconcile, no “final_FINAL_v3”.
- Editors write; readers read. You decide, and can change it any time.
- Invitations work once, only for the address you sent them to.
EXT. YOUR AI — CONTINUOUS
Your AI, in its own colour.
Connect Claude or ChatGPT to your account and it works the way a collaborator does: it reads the script, the treatment and your notes, and its edits land on the page in a colour that is unmistakably not yours. Undo takes them out. Disconnect it in one click.
- It can reach only what you can, and only after you say yes.
- Stream never sends your work to an AI on its own. Connecting yours is free on every plan.
INT. THE WORLD — DAY
The whole project, not just the script.
A treatment, a series bible and a drawer of notes live beside every script, linked to one another. Every draft is kept — named, dated, one click from the page — so you can always go back to the version that worked.
INT. THE VAULT — NIGHT
Your work stays yours.
- Encrypted. At rest, and every backup and draft sealed again under its own project’s key.
- Never training data. No ads, no analytics on what you write, no selling it.
- Take it with you. Download everything as ordinary files, any time.
- Gone means gone. Delete your account and every project and draft goes with it.
