Crystallize your cognition at the speed of thought
An open-source, system-wide voice dictation and AI assistant for Android and Windows. Transcribe in sub-seconds via Groq Whisper, or switch to 100% local offline transcription with intelligent AI commands. Works instantly in any application.
The Dictation Bottleneck
Traditional dictation systems are either slow, unpunctuated, or restricted to a specific custom keyboard. Google's streaming STT dictates word-by-word and frequently gets homophones wrong because it lacks contextual sentence-level comprehension. Furthermore, closed-source keyboards pose a massive telemetry and data privacy risk.
The Fluence Approach
Fluence waits for you to finish your sentence/phrase, transcribes it using OpenAI's Whisper Large v3 model on Groq's LPU inference hardware in less than a second, and automatically injects fully-punctuated, context-aware text directly at your cursor.

Frequently Asked Questions
Is Fluence free to use?
Yes, Fluence is 100% free and open-source under the Apache 2.0 license. Since transcription is processed using API keys, you only pay for your own usage. Groq offers a generous free tier for developers, and even on paid tiers, Whisper transcription costs a fraction of a cent per hour of usage. Offline mode using SenseVoice has no API cost whatsoever.
Does Fluence track my keystrokes or usage?
Absolutely not. Fluence does not record, store, or transmit keystrokes, typing speed, session length, usage frequency, or any behavioral data whatsoever. There are zero analytics libraries, zero crash reporters, and zero background telemetry beacons in the codebase. The app contains no tracking code of any kind. Every line of this is verifiable since the project is fully open source.
How is my data privacy protected?
Fluence is built on ironclad privacy principles. There is zero telemetry and no server logging of any kind. Audio is recorded, sent securely to the Whisper API, transcribed, and instantly discarded from both the API and your device. Your Groq API key is stored inside the Android Keystore using hardware-backed encryption, never in plain text. In offline mode, no audio or data ever leaves your device at all.
Can it run completely offline?
Yes! Fluence fully supports 100% offline, on-device voice dictation. Toggle "Offline Transcription" in settings and the app downloads Alibaba's optimized SenseVoice-Small ONNX model (~230 MB, one-time download). Once downloaded, all transcription runs completely locally on your device with zero internet connectivity and zero data egress. Offline mode also works with AI Agent Mode for local text editing commands.
Does it support languages other than English?
Yes. Whisper Large v3 supports 99+ languages with high accuracy and automatic language detection. Just speak in your native language and it transcribes correctly. SenseVoice offline mode also supports multiple languages including Chinese, Japanese, Korean, and more, with automatic detection.
