The Big Picture

Write your script on the left, storyboard it on the right. The Style tab extracts visual styles from reference images, the Library stores them, and the Builder turns them into prompts for any AI generator. One OpenRouter key (Settings) powers writing + analysis; a fal.ai key powers images. Settings has four independent model pickers — Writing (Format), Prompt-Writing (✨ buttons), Style Builder, and Vision — mix and match, e.g. Haiku for prompts, Sonnet for formatting. Everything saves automatically in your browser — refresh-proof.

Writing

Just write. Format applies industry screenplay format with AI — to the whole script, your text selection, or gutter-selected lines. (Partial formats automatically send the surrounding lines as read-only context, so an excerpt formats correctly even mid-dialogue or mid-scene.) Preview shows the true page layout (margins, indents, bold sluglines). Cards shows every scene as a card with synopsis + runtime + thumbnail. Guide is the screenplay-format cheat sheet. ⏲ runtime estimates appear on scenes and the toolbar (1 page ≈ 1 minute). The ◑ contrast slider (next to A+) tunes the editor text for reading comfort — middle = theme default, right = punchier, left = softer; it remembers your setting per browser and works with all 14 themes.

The Line-Number Gutter (your control strip)

Gold line = has a storyboard — click to jump to it. Drag over numbers to select lines, then: 🔒 Lock protects them from Format (blue), Format formats just them, + Add Panel drops a panel there. Click a locked line + Lock = unlock. Half gold/half blue = board + lock on the same line.

Storyboarding

Scenes appear automatically after Format. Each card: prompt field (grows as you type — Shift+Enter for new lines; empty = auto from script; ✨ = AI writes a shot prompt from the scene; Auto loads the raw auto-prompt; Go ▶ or Enter generates), meta row (shot type · seconds · dialogue), gallery (← → arrows, + tile = new concept). Storyboard All (top bar) offers ⚡ Quick (scene text as prompt) or ✨ AI-Enhanced (AI writes a custom shot prompt per scene first — better frames). Hover a frame: ★ set primary · ↻ Remix (regenerate using that image as base) · ⤓ download · × delete. + Generate More adds concepts; Start Over wipes and regenerates; Upload inserts your own images (multiple at once).

Panels are boards you place yourself: + Add Panel at the cursor or gutter-selected line, or + Sketch to Storyboard to draw the shot and let AI render it. ✨ AI Panel = put your cursor on any line (or select several / drag in the gutter) — the AI reads the whole surrounding scene — plus your tagged element profiles (Elements button), each character's intro description from the script, the previous scene's situation, and a story outline of every scene — then writes a panel prompt for that exact beat with consistent character looks. AI-Enhanced Storyboard All uses the same full context per scene. (Tip: profile your cast in Elements and every AI prompt keeps them on-model.) The panel lands on that line with the prompt filled in; tweak it, then Generate. Every panel card also has its own ✨ AI button to (re)write the prompt for its line anytime. Panels sort into script order automatically and shift when you add/delete lines. Click the Line N ↪ badge on a panel (or a scene card's slugline) to jump straight to that spot in the script.

Animatic (teleprompter)

▶ Animatic opens on a title card (project name + runtime, 3s), then line 1 eases up from below into center before the clock starts — the entire script scrolls up the screen in real time, paced by each scene's runtime (or its duration field), while the matching panel shows above, switching exactly when the scroll reaches its line. The current line glows white. Click or Space = pause, ←/→ = skip 5s, Esc = close. ⬇ Video exports the same playback as a .mp4 video file — fast encode, no waiting for real-time playback (Esc cancels; falls back to real-time .webm on older browsers). Export → Storyboard / Look Book PDF prints every scene + panel with images, synopsis, shot info, and dialogue.

Style DNA → Consistent Boards

Style tab: drop reference images → AI extracts a 16-field Style DNA → save as a preset. Library: "Use as Master Style" pipes a preset into the storyboard generator — every frame renders in that look. Export/Import moves your library between machines. Builder: preset + subject (typed, pasted, pulled From Script Selection, or AI-Distilled) → ready prompts for Midjourney/Flux/Runway/etc.

Script Reports 📊

The 📊 button (script toolbar) opens reports computed live from your script: dialogue counts + word share per character, a who's-in-which-scene matrix, INT/EXT and DAY/NIGHT splits, and runtime. Casting and scheduling gold.

AD Breakdown + Element Profiles

In Preview: select any word → click a category chip (Cast red, Props purple, Sound brown...) → every occurrence highlights, and prints that way. Click a highlight to remove. Elements opens profiles: give MARA a one-line visual description and it auto-injects into every panel prompt where she appears — same face, every frame. ✨ Gen Ref goes further: it generates a reference image from the profile, and whenever exactly one profiled character is in a panel, that reference becomes the image base — the real consistency lever. Most storyboard models are text-to-image only, so the ref path uses a dedicated Character Ref Engine (Settings): Flux img2img, Seedream 4 Edit, Nano Banana 2, or Qwen Edit.

Revisions & Drafts

Rev turns on Hollywood colored pages: pick blue/pink/yellow/green and every edit gets marked (gutter edge + colored text in Preview/PDF). Drafts stores snapshots — one is taken automatically before every Format, so a bad AI format is one Restore away.

Files & Export

New starts a fresh project — script, boards, locks, tags and revision marks are cleared, but your current script is auto-saved as a draft snapshot first (Drafts button). Save/Open = full project file (.walrus) — your backup and the way to move between machines. Open also imports .fountain scripts (synopses flow into Cards). Export: Screenplay PDF (print dialog → Save as PDF, breakdown colors included), Screenplay + Storyboards PDF (each scene/panel's primary frame printed inline right at its spot in the script), Look Book PDF, Shot List CSV (every scene + panel with shot/duration/dialogue — opens in Excel/Sheets), Fountain, plain text. PDFs get an industry title page (set Author/Contact in the Export window) and scene numbers in the margins; filenames use your screenplay title automatically. Everything else persists in this browser automatically.

If something looks stale

Check the version badge next to the logo — hard refresh (Ctrl+Shift+R) if it doesn't match the latest announced version.

Scene Headings (Sluglines)

INT. inside  ·  EXT. outside  ·  INT./EXT. both — then LOCATION, then TIME after a dash. Keep it to one line.

INT. COFFEE SHOP - MORNING
EXT. HOUSE - BACKYARD - CONTINUOUS

Time can be relative: CONTINUOUS, MOMENTS LATER. Mid-scene shifts can use an uppercase subheading without INT./EXT. (e.g. THE KITCHEN).

Action

Present tense. Only what the camera sees and hears — no inner thoughts, no flowery prose. UPPERCASE a character's name on first appearance; uppercase SOUNDS and key PROPS sparingly. Never write camera shots — that's the director's job.

Character & Dialogue

Name in uppercase above the dialogue. Extensions: (V.O.) voiceover · (O.S.) off screen · (PRE-LAP) dialogue starts before the scene · (CONT'D) same speaker twice in a row.

Parentheticals

A performance note or pause on its own line between name and dialogue — use sparingly.

Make it a double today.

Transitions

Uppercase with a colon: CUT TO: DISSOLVE TO: MATCH CUT TO: — only when crucial to the story. Editing belongs to the editor.

Montage & On-Screen Text

BEGIN MONTAGE / END MONTAGE on the left. On-screen text: CHYRON: followed by the text.

Why it matters

Producers skim hundreds of scripts — wrong format is a fast excuse to discard yours. The format also keeps the 1 page ≈ 1 minute rule intact and lets every department (AD breakdowns, production design, budgeting) read the same blueprint. The rules are strict, but voice lives inside them — Sorkin's dialogue rhythm, Spike Lee's action commentary, Kaufman's blurred montages all fit the format.
