OpenVox AI is a local text-to-speech (TTS) application designed for Mac, Windows, and iPad. It aims to provide privacy-focused AI voice generation with a user-friendly interface, allowing users to create realistic voiceovers, design new voices, clone reference voices, generate multi-speaker conversations, and convert written books into audio.

The toolโ€™s core operations run directly on the userโ€™s device, without requiring cloud-based voice generation. Files, scripts, and generated audio remain local, enhancing privacy and giving users more control over their content. After the one-time model download, core voice generation can work offline, reducing the need for a continuous internet connection.

OpenVox AI offers multiple AI voice models, a wide range of voices, and support for many languages. It also provides functionality for creating custom, reusable voices. The app can convert text files into expressive speech and allows users to control speech parameters such as speed and pitch. For larger projects, OpenVox AI includes batch processing, audiobook workflows, and multi-speaker conversation support.

A voice cloning feature is also included, enabling users to upload or record samples and manage cloned voices locally. On Mac, OpenVox AI is optimized for Apple Silicon. On Windows, it supports NVIDIA CUDA acceleration for faster generation on supported GPUs, while also offering CPU mode for non-NVIDIA systems. On iPad, it brings the local AI voice workflow to a more portable form.

OpenVox AI offers a free download and does not require users to create an account.

    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

  1. Has almost everything I need

    I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

  • RS-X: Framework-agnostic reactive state and expressions for JavaScript/TS
    Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 5 months ago
  • Show HN: I combine Htmx, LiveView and SolidJS for interactive server components
    I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx.
