The experiment came first.The native Mac app is a new build.

Openbroca Origin is Timothy Lau’s personal MIT-licensed open-source project and the early experimental implementation that explored the idea now developed as Openbroca. Origin is an Electron app for macOS, Windows, and Linux, with configurable local and cloud speech recognition and multiple language-model providers. It remains maintained for people who want to study the approach, adapt the code, or use a free open-source version. The current Openbroca product at openbroca.com is different software: a native Swift app built independently for macOS 15 or later. The two projects share history and a product idea, but they do not share code. Features, privacy behavior, platforms, downloads, and system requirements described on this website apply to the current Mac product unless a page explicitly says Openbroca Origin. For the open-source implementation, use its GitHub repository as the source of truth; for the native Mac app, use Openbroca’s current product, pricing, and privacy pages.

Origin was an exploration of system-wide voice input: a practical place to test how speech recognition, text refinement, and provider choice could work together. The current Openbroca app carries that product idea forward with a focused Mac experience, but it was written independently in Swift rather than built from Origin’s Electron code.

The distinction is technical, not a change in respect for the project. Openbroca Origin remains free, open source, and maintained. Its MIT-licensed source is available for anyone who wants to learn from it, modify it, or use its cross-platform implementation.

Both projects point at the same belief: voice input should be the best-feeling, smallest, most effortless way to write — not a novelty, not an accessibility footnote, but the default. They simply pursue it with different technology, platforms, and product boundaries.

The name isn’t a coincidence. Broca’s area is a language-related region in the posterior inferior frontal gyrus of the dominant hemisphere, usually the left. An NCBI neuroanatomy overview describes its role as spanning language production and comprehension, while noting that speech depends on a wider network.

Broca’s best-known patient was Louis Victor Leborgne, nicknamed “Tan” because that was the only word he could reliably speak. That gap — between the thought you already have and the words that finally appear — is the exact gap this product exists to close.

Open + Broca: an open door to the part of your brain that already turns thought into words. Everything we build points at one goal — getting out of the way between what you mean and what shows up on screen.

Timothy Lau created and publishes Openbroca Origin as a personal open-source project. He is also the Founder of Openbroca. You can find him on X and LinkedIn.
