How will this fit
your workflow?

Tell us your monthly volume, language pairs and current setup. We'll help you choose managed services or a self-managed subtitling platform to fit your delivery requirements.

  • Can you work under our brand?

    Yes, we can scope a white-label service or technology setup for media-services and playout providers. Your team keeps the client relationship. We agree responsibilities, communication, approval and delivery requirements around the channels and customers you serve.

  • Can we keep our current tools?

    Yes. Use the platform for the stages that help your team, then return the files to your existing workflow. SRT import and SRT, WebVTT or EBU STL export support file-based handovers. Check your required formats and review process before deciding whether it complements or replaces your current editor.

  • How does self-managed subtitling work?

    Create AI transcripts, edit subtitle cues on a timeline, translate with surrounding context, manage terminology and language versions, resync after edits, merge timed assets, run configurable QA and export subtitle files. Shared projects and vendor assignments help organise the people working on each language.

Let's plan your workflow.
