OpenFlow is a small native app for Mac computers that lets you dictate text with your voice instead of typing. It sits quietly in your menu bar, and while you hold down a key and speak, it turns your words into clean, polished text and types it directly into whatever app you are using, whether that is an email client, a terminal window, or a chat box. When you speak, your audio is sent to a service called Groq for fast transcription, using an AI model called Whisper, followed by a quick cleanup pass. You need to bring your own free Groq account and API key, and OpenFlow says nothing is stored on anyone else's server. It describes itself as an independent, open source take on the idea of system-wide AI dictation. Beyond plain dictation, OpenFlow offers a few extra modes. A hold-to-talk shortcut records only while you hold the key, so a quick accidental tap does not trigger it. A voice assistant mode lets you select some text and speak an edit, such as asking it to sound friendlier, or lets you speak a fresh request when nothing is selected. A command mode reworks text you just produced, and commands can be chained together, so you might ask it to shorten something and then translate it. There is also an optional wake phrase, "Hey Flow," which is detected entirely on your Mac using Apple's built in speech recognition, so no audio leaves your device just for that. The cleanup pass removes filler words like "um" and "uh," fixes self-corrections where you change your mind mid-sentence, adds punctuation, and formats spoken lists, all with a timeout so it never leaves you stuck waiting. OpenFlow also supports spoken snippets that expand into saved text, a personal vocabulary for names and jargon, a floating overlay showing a live waveform, and recognition in over 100 languages. To use it you need a Mac running macOS 14 or later, and a free Groq API key. Building the app from source only requires the Swift toolchain, the full Xcode installation is only needed for running its test suite.
