Problem
Typing speed limits productivity for users who need to generate large amounts of text quickly, especially when working across multiple devices or languages. Conventional keyboards also lack built-in assistance for tone adjustment, summarization, and secure handling of voice data.
Solution
Whisper Flow delivers an AI‑driven voice keyboard that captures spoken input and converts it to highly accurate text in real time. The app runs on macOS, iOS, and Android, offering both on‑device (local) and cloud transcription pipelines so users can choose the optimal balance of latency and compute resources. Integrated large‑language‑model (LLM) services provide grammar correction, five selectable tone‑rephrasing styles, and fifteen pre‑built summary templates to streamline communication. Built‑in translation supports over 100 languages, while a personal dictionary continuously learns user‑specific terminology for consistent accuracy. All audio streams are encrypted and processed locally when possible, ensuring privacy without sacrificing performance. Results sync across devices through a secure cloud layer, enabling seamless workflow continuity. A free tier grants 1,000 words per week, and a premium subscription unlocks unlimited usage and advanced AI features.
