One Workflow, From Script to Show Night
Keep preparation, editorial review, rehearsal, live cueing, room-visible projection, and audience-phone delivery in one accountable workflow.
Ingest & Analyze
Upload a Word script and review how speakers, dialogue, and formatting have been structured before anyone treats the result as cue-ready.
Translate & Adapt
Create draft translations across 100+ supported languages, then let the people responsible for the performance review wording, line breaks, and context. Live viewer languages still depend on your plan.
Run Projection + Mobile
Cue room-visible projection and enabled audience-phone languages from the same Operator Cockpit, while keeping their delivery conditions clear.
Script Preparation That Leaves Editorial Decisions Visible
Reduce mechanical cleanup after a Word-script upload while keeping the script open to review. SurtitleLive helps separate speakers, dialogue, and stage directions so the team can decide what belongs in each cue before translation or rehearsal.
- Automatic character detection to review
- Line-break suggestions for readable cues
- Drag-and-drop structural editing
- Revise cues when the script changes
AI-Assisted Drafts, With Human Editorial Responsibility
AI can help create a first draft for preparation; it does not decide what an audience should receive. Your team reviews language, tone, line breaks, timing, and cultural context before performance.
- 100+ supported translation languages
- Optional style guidance for draft translations
- Line-by-line review of tone and context
- Re-translate drafts when scripts change
Live Performance Control
The Operator Cockpit supports prepared, rehearsed cueing in a dark backstage environment. It gives an operator recovery controls; it does not replace a show plan, a trained person, or a backup path.

Cue navigation and blackout controls support live operation without relying only on a mouse.
Direct Jump
If performers skip a passage, jump to another line by ID or search text and recover the prepared cue path.
Low Latency
Designed for low-latency cue updates from the Operator Cockpit to projection and audience viewers; test the actual venue conditions before making promises to an audience.
Projection + Mobile Surtitles
Use Projection Mode for LED screens or projectors while audience members follow enabled languages on their phones. If ASM and the Projection Window are already open, prepared local projection can keep running during venue internet loss. Audience phones still depend on cloud delivery.
Built for a Responsible Live-Text Workflow
One workspace supports script preparation, reviewed translations, live deployment, and audience access for a single show, festival, or season. The production still decides its scope, staffing, access information, and contingency plan.
Granular Collaboration
Invite translators, directors, and operators, then set Edit, Review, or Read-only access to match the work each person has agreed to do.
Audience Access
Audience members scan a QR code to enter. Deployments stay live for the plan's visible window.
Deployment Regions
Lite deployments use system-selected regional placement. Pro deployments can choose US, EU, or Asia.
Multi-Language Deployment
Deploy your source script plus plan-limited translated languages so each audience member can choose an enabled viewer language.
Multi-Project Workspace
Validate a workflow with one project or manage multiple active productions from one workspace.
High-Volume AI Processing
Use weekly AI credits for script analysis, translation drafts, and review workflows; keep final editorial responsibility with the people presenting the work.

Common Questions about SurtitleLive
Practical questions about preparing and delivering live text for performances.
How does SurtitleLive work with PowerPoint or slide-based surtitles?
PowerPoint can work for simple slide-based surtitles. SurtitleLive adds live cue controls, jump recovery, blackout, and one cue path for projection plus audience phones.
Do audience members need to download an app?
No. Audience members scan a QR code and open the Viewer in their mobile browser. They can choose from the languages the production has enabled; no app-store download is required.
Is this suitable for opera surtitling?
Yes, when a trained operator prepares and rehearses the cue path. Manual cueing lets the operator align surtitles to musical tempo and performance choices.
Can I use Projection Mode with LED screens and projectors?
Yes. Projection Mode is the room-visible output path for LED screens and projectors: open the Projection Window on the display computer and cue it from the same live controls. Mobile surtitles are separate and remain cloud-delivered.
