Trelby is a free, multiplatform screenwriting program designed to simplify and streamline the writing process. It features a clean, intuitive interface with built-in formatting and pagination to meet industry standards. Writers benefit from auto-completion, spell checking, and multiple viewing modes, including draft view and WYSIWYG. Its flexibility and efficiency make it suitable for both novice and professional screenwriters.

Trelby supports importing and exporting scripts in formats like Final Draft, Celtx, Fountain, Adobe Story, and Fade In Pro. PDF generation, customizable fonts, and watermarks, along with character databases, scene reports, and script comparison, help writers manage revisions and maintain consistency.

Script formatting and management

Trelby automatically enforces proper script structure, saving time and minimising formatting errors. Its detailed reports on scenes, locations, dialogue, and characters help writers track story elements and maintain narrative coherence. The built-in script comparison tool highlights edits and changes clearly, supporting efficient collaboration, organised revisions, and overall project management, making it a practical and reliable choice for both novice and professional screenwriters.

The program supports multiple file formats, enabling seamless integration with other screenwriting tools. Users can import scripts from plain text or industry-standard formats and export them to PDF, HTML, RTF, or Final Draft XML. This versatility ensures projects remain compatible across various software environments, simplifying collaboration with colleagues, sharing work with editors, or submitting scripts to producers while maintaining proper formatting and workflow consistency throughout the process.

While feature-rich, the software does not include advanced multimedia or storyboarding capabilities. Users seeking integrated video, audio support, or cloud collaboration will need additional tools. Being community-driven, its development may result in slower updates compared with commercial software. Despite these limitations, it remains a reliable and efficient solution for drafting, formatting, and managing screenplays, providing essential tools for both novice and professional writers.

Trelby is a reliable and versatile screenwriting program that balances simplicity with practical, powerful features. Its emphasis on accurate script formatting, detailed reporting, and cross-platform compatibility makes it suitable for both beginners and professional writers. Although it lacks multimedia integration, the program provides an efficient, distraction-free environment for drafting, editing, and organising screenplays, helping users focus on creativity and maintaining a consistent, professional workflow.
