AI Script Editor
Highlight any passage and AI rewrites it instantly in a side panel. Accept what works, archive what you might need later, and watch the refined text flow back into your script — highlighted so you always know what changed.
Two Modes. One Studio.
The command center for your story. Chat with AI, break your narrative into beats, build page-by-page scaffolds, write treatments, and apply everything directly to your script — all from a single, integrated workspace. Eleven industry-proven templates. One seamless flow from idea to final draft.
Where ideas take shape.
Brainstorm with AI. Get scene rewrites, dialogue polish, and story ideas in a conversational flow.
Break your story into structural beats using any of eleven templates from Save the Cat to The Writer's Journey.
Generate a page-by-page scene outline from your beat structure. AI populates each scene, then applies it to your script.
Develop full narrative treatments that connect your beats to polished prose — ready for pitch decks and producers.
Save multiple chat sessions, brainstorms, and development threads. Nothing gets lost in the creative process.

World Building
Locations are auto-detected from your scene headings the moment you import a script. Generate AI-powered reports with history, culture, and atmosphere for any location.
Everything between final draft and first day of shooting. Build industry-standard shot lists, sketch storyboards, analyze producibility, navigate your script like a spreadsheet, and preview scenes with AI — all from a single, integrated workspace.
From page to production-ready.
Build industry-standard shot lists with camera sizes (WS, MS, CU, ECU), angles (eye level, low, high, Dutch), and movements (dolly, crane, Steadicam, drone). Organize by scene, add notes, and export for your DP and camera team.
Visualize your scenes as sketch-style storyboard frames. Each panel links to a shot in your shot list with scene labels, shot sizes, and space for director's notes — all in a hand-drawn pencil aesthetic.
See your script through a producer's eyes. Get a Contained Score (0–100), budget tier estimate, location census (INT/EXT breakdown), speaking cast count, night shoot percentage, and actionable producer insights.
Rate how feasible your script is for AI-driven filmmaking. Scores across five dimensions: cast complexity, action & physicality, environment generation, production scale, and continuity & period accuracy.
A spreadsheet-style view of every scene and character. Sortable columns for scene number, heading, location, page length, and per-character arc notes. Includes an inclusivity analysis panel showing dialogue distribution.
Design AI character voices with Qwen3-TTS from natural language descriptions. Generate cinematic scene preview videos with LTX-2. Export detailed character profiles as JSON for LTX Studio — no external API keys needed.
Build industry-standard shot lists with every camera size, angle, and movement. WS, MS, CU, ECU, OTS — organized scene by scene with dialogue references and director’s notes.
New Feature
Table Read turns your screenplay into a live performance. Every character gets their own distinct AI voice — automatically assigned, fully customizable. The active line glows amber as it plays. Hear exactly how your dialogue sounds before you step on set.
New Feature
Get the kind of feedback a professional script reader gives a studio — inside HeadWriter Studio's Production panel. Your script is graded on six elements, broken down act by act, with concrete rewrite directives and a final reader verdict.
Strong opening hook. MAYA's introduction immediately establishes tone. Inciting incident lands on page 12, slightly late but effective. The procedural mechanics are clear.
Each act gets a page range, summary, strength/weakness breakdown, and a concrete rewrite directive.
Every major character assessed individually — arc, voice, and one specific suggestion to make them land harder.
Prioritized, specific recommendations — not "add conflict" but exactly which scene and why.
Export as a formatted coverage document — the same layout used by production companies.
New Feature
Upload PDFs, Word documents, RTF files, and plain text — all stored in your project's Research Library. Pin any file or note and it flows directly into every AI conversation as live context. Your historical research, technical references, and world-building notes become part of how the AI thinks about your story.
