# Whisperstream Whisperstream is private local dictation software for Windows. It captures your voice with a push-to-talk hotkey, transcribes it entirely on your PC using an on-device speech model, and inserts the result into the app you are using. Your microphone audio is not sent to a transcription service. Optional AI enhancement is off by default and can use a downloadable Local model, Ollama, or a provider the user configures with their own key. One-time purchase at $29 USD for 1 device or $49 USD for up to 2 devices, no subscription. ## Key facts - Platform: Windows 10, Windows 11 (64-bit) - Pricing: $29 USD for 1 device or $49 USD for up to 2 devices, one-time purchase, no subscription - Pricing details (machine-readable): [pricing.md](https://whisperstream.io/pricing.md) - Free trial: 7 calendar days from the first dictation that produces text, no account or credit card required - Publisher: Lanreal Technologies Inc., Toronto, Canada - Product page: [whisperstream.io](https://whisperstream.io) - Support: [support@whisperstream.io](mailto:support@whisperstream.io) - Publisher contact: [contact@lanreal.io](mailto:contact@lanreal.io) - GitHub org: [github.com/lanreal-io](https://github.com/lanreal-io) - Company website: [lanreal.io](https://www.lanreal.io/) ## Features Full feature page: [whisperstream.io/features](https://whisperstream.io/features) - On-device transcription: Speech recognition happens locally on the CPU using the model selected for the dictation language. Automatic selection uses NVIDIA Parakeet or Qwen3 ASR. Cohere Transcribe is an optional Manual choice for supported languages. Microphone audio is not uploaded for transcription. - Lockdown Mode: Keeps Whisperstream's transcription, AI cleanup, and history on your PC, limits cleanup to Local, and can password-protect saved history. Safe local diagnostics remain available for user-controlled bug reports and are never uploaded automatically. It does not control the app receiving inserted text or disable Agent Speak. - Push-to-talk hotkey: Hold a hotkey to dictate, release to stop. Default is Right Shift, remappable to any key; a toggle mode is also available. No admin rights needed. - Text insertion: Uses clipboard paste or simulated keystrokes to deliver text to compatible fields. Some applications and managed or remote environments can block delivery. - Transcript history: Encrypted text and audio history is on by default with seven-day retention. Users can turn text or audio saving off, change retention, search, replay, copy, save an audio copy, and delete records locally. History is not cloud-synced. - Audio file import: Transcribes audio files you already have through the selected on-device speech model. Whisperstream does not upload the source audio. If online enhancement is enabled, it can send the resulting transcript to your configured provider. - Optional AI cleanup: Off by default. Removes filler words, fixes grammar and punctuation, and applies spoken self-corrections. The Local provider uses Gemma 4 E2B on the user's PC. Ollama, Gemini, OpenAI, Anthropic, and configured OpenAI-compatible providers are also supported. - Automatic profile switching: Gives each app or website its own enhancement profile and applies it automatically by detecting the focused window. Start from an included profile or write your own; route by app or by a specific site, with a default everywhere else. - Custom dictionary: Filters unwanted words or phrases and replaces recurring recognized terms. Matching is case-insensitive and applies to completed dictation. - 39 languages: Transcribes 39 selectable languages on-device across English-only and multilingual speech-model families. A recording should contain one language, and changing to a language unsupported by the active model can require another model download. - Offline core: After the required speech model is downloaded, recording and speech recognition work without a connection. The downloaded Local enhancement model can also work offline after setup. Updates, model downloads, license actions, and configured online enhancement providers still use the network. - Authenticode-signed installer: Windows can verify Lanreal Technologies Inc. as the publisher, and IT teams can use that exact name in managed environments. SmartScreen may still show a reputation warning. - Custom style prompt: Give AI cleanup your own prompt with custom formatting or style instructions (tone, terseness, spelling, bullet formatting, house style). Custom profiles use the configured enhancement provider. - System-volume ducking: Optionally lowers (to 20 percent) or mutes system volume while you dictate, then restores it on release. - Runs on CPU, no GPU required: Core transcription runs on a normal processor; a GPU is only used for the optional AI cleanup. Works on 8 GB of RAM, 16 GB recommended. ## Canonical pages - [Home](https://whisperstream.io/) - [Features](https://whisperstream.io/features) - [About](https://whisperstream.io/about) - [End User License Agreement (EULA)](https://whisperstream.io/eula) - [Privacy Policy](https://whisperstream.io/privacy) - [Website Privacy Policy](https://whisperstream.io/privacy-website) - [Subprocessors](https://whisperstream.io/subprocessors) - [Terms of Service](https://whisperstream.io/terms) ## Product documentation - [Install and configure Whisperstream](https://whisperstream.io/docs) - [App basics, licensing, updates, and uninstall](https://whisperstream.io/docs/getting-started/app-basics) - [Recording controls and last-transcript actions](https://whisperstream.io/docs/dictation/recording-controls) - [Languages and speech recognition models](https://whisperstream.io/docs/dictation/languages-models) - [Microphone, playback, and system audio](https://whisperstream.io/docs/dictation/audio) - [Live Preview](https://whisperstream.io/docs/dictation/live-preview) - [Text insertion and compatibility](https://whisperstream.io/docs/dictation/text-insertion) - [Dictionary filters and replacements](https://whisperstream.io/docs/dictation/dictionary) - [Local, Ollama, and cloud enhancement providers](https://whisperstream.io/docs/enhancement/providers) - [Profiles, Email mode, app detection, and site detection](https://whisperstream.io/docs/enhancement/profiles-routing) - [Transcript and audio history](https://whisperstream.io/docs/data/transcript-history) - [Lockdown Mode](https://whisperstream.io/docs/data/lockdown-mode) - [Pin Mode](https://whisperstream.io/docs/workflows/pin-mode) - [Agent Speak for Codex and Claude Code](https://whisperstream.io/docs/workflows/agent-speak) - [Settings and data locations](https://whisperstream.io/docs/reference/settings-data-locations)
