Features and specs

What each product offers, as listed by its team.

Modular JavaScript 5 features
Subti.app 8 features
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.
  • Clickable Subtitles
    Option-click words or select phrases directly from VLC subtitles
  • Contextual Translation
    Translates words and expressions using the surrounding subtitle context
  • Vocabulary Review
    History, personal Dictionary, and spaced repetition review
  • Anki export
    Export saved vocabulary to Anki with context
  • Local-first
    Supports local translation backends and requires no account
  • VLC integration
    Works as a macOS companion overlay for VLC 3.0+
  • Privacy
    No behavioral telemetry
  • System Requirements
    macOS 14+

Questions & Answers

As answered by people managing Modular JavaScript and Subti.app.

What makes your product unique?

Subti.app's answer:

Subti makes VLC subtitles interactive on macOS. You can click individual words or select whole phrases, get contextual translations without leaving the film, save useful vocabulary, review it with spaced repetition, and export it to Anki. It is local-first, requires no account, and can work with local translation models

Why should a person choose your product over its competitors?

Subti.app's answer:

Subti is focused on a simple workflow: watch, click, understand, save, and review. It works directly with VLC and local video files instead of requiring a browser-based streaming service. It also supports phrase-level contextual translation, local translation backends, spaced repetition, and Anki export in one macOS app

How would you describe the primary audience of your product?

Subti.app's answer:

Language learners who watch films and TV shows with subtitles, especially intermediate and advanced learners who want to learn vocabulary and expressions from real dialogue without constantly switching between the video player, translator, notes, and flashcard apps

What's the story behind your product?

Subti.app's answer:

Subti started from a personal frustration with learning languages through films. Looking up an unfamiliar word usually meant pausing VLC, opening a translator, copying the subtitle, saving the word somewhere, and then returning to the film. Subti was built to keep that entire workflow inside the viewing experience

Which are the primary technologies used for building your product?

Subti.app's answer:

Subti is a native macOS application built in Swift. It integrates with VLC through a transparent interactive overlay and supports local language models and Ollama for translation. The web and licensing infrastructure uses Cloudflare Workers, D1, R2, Paddle, and Sparkle for updates
