SpeakoFlow

SpeakoFlow is a free and open-source voice-to-text application that lets you dictate into any app on Windows, macOS, or Linux. Press a hotkey, start speaking, and your words appear in real-time in email, editors, chat, or wherever your cursor is. It claims speeds over 150 words per minute, far outpacing average typing. The tool is completely free, with no account needed and no data sent to the cloud unless you opt in.

Beyond basic dictation, SpeakoFlow includes several AI-powered features. The "Generate with Flow" mode lets you say a trigger phrase (like "Hey Flow") followed by a natural-language request, and the tool generates a reply, email, or draft directly into your active app. An AI cleanup feature strips filler words, fixes grammar, and adjusts tone (Professional, Friendly, Concise, or custom). There's also a voice-activated assistant you can summon from any app, which can answer questions, read your screen, and even speak responses back to you. The screen-aware feature lets the assistant see what's on your display when you allow it, providing context-aware answers. All of this runs locally by default, keeping your voice data on your device.

SpeakoFlow is ideal for anyone who types a lot — writers, developers, students, or professionals with repetitive strain injuries. Its real strength is how it works system-wide, so you can use it in any application without switching windows. The open-source, MIT-licensed code means you can inspect, modify, or trust that it's not doing anything shady. The main caveat: it's built by an independent developer and may lack the polish or support of paid tools. For a free, private, and surprisingly capable dictation tool, it's a standout option.
