GPU-accelerated voice dictation for Windows that runs entirely on your machine. Press Ctrl+Shift+Space, speak, and text appears wherever your cursor is — Slack, ChatGPT, Cursor, any app. Whisper AI runs locally via Vulkan on NVIDIA, AMD, and Intel GPUs, so your audio never leaves your device. Eleven model sizes (Tiny 75 MB → Large-v3 3.1 GB) let you trade speed vs accuracy. Free tier: 500 words/day, no credit card. Lifetime $49.99, Pro $7.99/mo.

100% Local Transcription
Speech-to-text runs entirely on your machine using Whisper AI. Your audio is never sent to any server, ever.
GPU Acceleration (NVIDIA, AMD, Intel)
Vulkan-accelerated transcription works on virtually any modern GPU. Falls back to CPU automatically if no compatible GPU is found.
Hotkey Dictation
Press Ctrl+Shift+Space (configurable), speak, release. Text appears wherever your cursor is — Slack, Teams, VS Code, ChatGPT, any app.
11 AI Models
Choose from 11 Whisper model sizes, from Tiny (75 MB, fastest) to Large-v3 (3.1 GB, most accurate). Pick the right speed/quality balance for your hardware.
Works Offline
Once a model is downloaded, no internet is required. Dictate on planes, in coffee shops with bad WiFi, or in air-gapped environments.
AI Post-Processing
Optional one-click rewrites: clean up filler words, turn dictation into a professional email, summarise, or translate. Choose from built-in modes or write your own.
Custom Processing Modes
Create unlimited custom modes with your own system prompts. "Code comment style", "casual Slack", "formal report" — whatever fits your workflow.
Cursor-Position Paste
HyperVoice tracks the foreground window, types text into it, then restores focus. Works in literally any Windows app — no per-app integration needed.
Free Tier, No Credit Card
500 words per day, forever. No time limit, no signup paywall.
Most dictation tools force a choice: cloud-based (fast and accurate, but your audio is uploaded) or local (private, but slow and clunky). HyperVoice is the first Windows-first dictation app to run Whisper AI 100% on-device with full Vulkan GPU acceleration — so it's as fast as cloud dictation while keeping every word of your audio on your machine. Combine that with hotkey-anywhere paste (works in any Windows app, no per-app integrations), eleven model sizes you can tune to your hardware, and optional BYOK post-processing (your text goes directly to your OpenAI or Anthropic API key, never through our servers), and you have privacy-by-default without compromising speed or workflow.
Knowledge workers on Windows who type all day and care about privacy: developers dictating code comments, commit messages, and chat to AI coding agents (Cursor, Claude Code, Copilot); writers and content creators turning raw thoughts into drafts; customer support and success staff replying to tickets; project managers writing status updates and bug reports; students dictating notes and essays; and professionals in regulated industries (legal, medical, finance) where uploading audio to a third-party cloud isn't an option.
Secondary audiences: power users who'd rather bring their own LLM API keys than pay double (subscription + per-token cost); people with accessibility needs who can't type comfortably for long periods; and anyone tired of monthly cloud-dictation subscriptions when a $49.99 one-time purchase does the same job better.
HyperVoice is currently in early-access beta with a growing community of individual users. We don't disclose specific customers, and as a privacy-first product we don't ask users what they're working on or who they work for.
That said, the early user base skews toward independent developers, technical writers, and professionals in regulated industries (legal, medical, security research) where the privacy guarantee is the deciding factor over alternatives.
HyperVoice started from a single frustration: typing is just so slow... Painfully slow...
I then downloaded some dictation tools and privacy was just a black box. Cloud dictation services upload your audio to servers, log it, and often retain it — fine for casual users, unacceptable for anyone touching client data, source code, medical records, or financial information. With the explosive growth of AI, I also do not want my voice online and in the cloud for what may happen in the future.
I had tried voice to text before but over the years, local Whisper models had quietly become accurate enough — and modern Vulkan-supported GPUs powerful enough — that a properly-engineered on-device dictation app could match the speed of cloud tools while keeping every byte of audio on your machine.
