FU Flow

FU Flow is a free, MIT-licensed dictation application for Windows 10 and 11 and for Ubuntu Linux 22.04 or newer (.deb or AppImage). You hold the right Alt key, speak, release it, and the text appears in whatever program the cursor sits in: a browser, Word, an email, a chat window or a code editor. A hands-free mode is available for longer passages. Before the text is pasted, a cleanup step that is on by default removes filler words such as “um” and “you know”, resolves spoken self-corrections and fixes punctuation and capital letters.

Speech recognition runs locally through whisper.cpp with Whisper models included in the installer, so dictation keeps working without an internet connection. There is no account, no API key, no weekly word limit and no subscription. GPU acceleration uses Vulkan where the hardware supports it, with a CPU path for machines without a usable card.

Thirty-three languages are available in Settings, with Greek and English the most tested. The app also carries a personal dictionary that learns names and terms it gets wrong, reusable snippets, local dictation history and a statistics card showing how much has been dictated. Dark and light themes are included, and the interface is available in English and Greek.

An optional setting can route speech to a remote OpenAI-compatible provider, in which case that provider receives the audio and sets its own fees. The local engine remains the default.

FU Flow is developed by Luram AI Agency in Thessaloniki, Greece. Version 0.9.8 is a beta under active development, and the full source is published on GitHub.
