Subtitle tools built for speed, accuracy, and modern workflows.
SubPilot Studio is an open source project focused on building tools for subtitle creators, translators, and localization teams.
We believe creating high-quality subtitles should be faster, more consistent, and less repetitive. Our projects aim to simplify the entire workflow—from transcription and translation to timing, quality assurance, and final export.
Whether you're subtitling anime, dramas, documentaries, educational content, or online videos, SubPilot Studio is designed to help you spend less time on repetitive tasks and more time polishing your subtitles.
Our ecosystem includes tools for:
- AI-assisted subtitle generation
- Subtitle translation workflows
- Timing and synchronization
- Quality assurance and validation
- Subtitle editing utilities
- Format conversion
- Automation for localization pipelines
- Open source first
- Developer-friendly APIs
- Clean and maintainable architecture
- Automation where it makes sense
- Human review always matters
- Fast, lightweight, and reliable
We welcome contributions of all kinds—bug reports, feature requests, documentation improvements, and pull requests.
Before starting work on a large feature, please open an issue so we can discuss the implementation together.
