How CosmoWhisper Compares
The only premium AI voice dictation app built natively for Windows.
Engineered Exclusively for Windows
For years, AI voice dictation was either locked behind Mac-only walled gardens or delivered as sluggish, memory-hungry web wrappers on Windows. We built CosmoWhisper from scratch to change that.
True C# / .NET Native Performance
No bloated Electron runtime sucking up battery and RAM. CosmoWhisper is engineered natively with the Windows App SDK, idling at under 90MB RAM and delivering true sub-500ms voice processing directly via Windows audio pipelines.
Absolute Privacy & Local Sovereignty
Your speech belongs to you. Run 100% offline with our local Whisper Race Mode for zero-cloud exposure, or enjoy cloud acceleration with strict Zero Data Retention (ZDR) where audio is discarded immediately after transcription.
Universal Windows Compatibility
No vendor lock-in or browser-only limitations. The Cosmo Capsule floats across multiple monitors, dictating cleanly into VS Code, Slack, Microsoft Office, Epic/EHR software, Notion, or command prompts with seamless global hotkeys.
Loved by 10,000+ Professionals & Teams
From medical clinics and law practices to engineering teams and writers—see how professionals type 4x faster and eliminate repetitive strain.
"I dictate PR reviews, commit messages, and technical documentation directly into VS Code at 160 wpm. CosmoWhisper cut my daily writing time in half. It handles camelCase, variable names, and code syntax without stuttering."
"Medical documentation used to eat 2 hours of my evening after clinic. CosmoWhisper accurately transcribes complex pharmacology and symptom histories into our EHR. The HIPAA-ready Zero Data Retention protocol made compliance sign-off effortless."
"In legal practice, confidentiality is absolute. Cloud-only dictation tools were an immediate non-starter for our compliance team. CosmoWhisper's local offline transcription gives us instant brief drafting without a single byte leaving the machine."
"Drafted an entire 45-page technical report in two afternoons. The intelligent punctuation and automatic filler-word cleaning mean my first draft is 95% publication ready. It feels like an extension of my vocal thought process."
"I live between Slack, Jira, and strategy documents. CosmoWhisper's lightweight floating capsule follows me everywhere in Windows. I haven't manually typed an email or roadmap brief in three months."
"Transcribing research interviews, conference notes, and manuscript drafts with sub-500ms latency. It's the only AI speech-to-text software on Windows that doesn't feel like a bloated Electron memory hog."
