Voice In. Words Out: The Free, 100% Offline Voice Typing App for Windows

A developer has released Vacanam, a free, open-source voice typing app for Windows 10 and 11 that works 100% offline. The tool uses local speech engines like Whisper for near-zero latency dictation and includes an optional built-in AI assistant for grammar polishing, all while keeping data private and on-device. Vacanam supports multiple languages and is available under the MIT License on GitHub.

Imagine this: You’re drafting a long email, writing a report, or responding to a wave of Slack messages. Instead of hunching over your keyboard and typing at 40 words per minute, you simply hold down Ctrl + Space , speak your thoughts at 150+ words per minute, and release the keys. Instantly, clean, perfectly punctuated, polished text appears right where your cursor is. Meet Vacanam — a free, 100% private, offline voice typing tool built for Windows 10 & 11. If you’ve ever tried built-in dictation tools or commercial transcription services, you’ve likely run into the same annoyances: We built Vacanam वचनम् — Sanskrit for Voice & Speech to fix all of this once and for all. Vacanam doesn’t trap you inside a special recording window. It works universally: Just click into any text box, hold Ctrl + Space, speak, and let go. When we talk, we hesitate, say "um" , repeat words, and forget punctuation. Vacanam features an optional Built-in AI Assistant that runs silently on your computer: Your voice and thoughts belong to you alone: Whether you dictate in English, Hindi, Spanish, French, German, Japanese, Arabic, Russian, or Portuguese , Vacanam accurately transcribes your speech in its native alphabet and script. Thanks to local speech engines Whisper , dictation happens with near-zero latency. As soon as you release the shortcut, your text appears in under half a second. | Feature | Windows Dictation | Wispr Flow | Cloud Apps Otter/Dragon | Vacanam 🎙️ | |---|---|---|---|---| Price | Free | $12 - $20 / month | $10 - $30 / month | 100% Free Forever | Works Offline? | ❌ No | ❌ No Requires Cloud | ❌ No | ✅ Yes 100% Offline | Privacy & Security | ⚠️ Sends to Cloud | ⚠️ Cloud-processed | ⚠️ Cloud Storage | ✅ 100% Local / Zero Cloud | AI Grammar Polish | ❌ No | ✅ Yes Cloud LLM | ⚠️ Basic / Cloud | ✅ Built-in Local AI | Global Push-to-Talk | ⚠️ Toggle only | ✅ Yes | ⚠️ App-dependent | ✅ Universal Ctrl+Space | Microphone Health Alerts | ❌ No | ❌ No | ❌ No | ✅ Mute / Low Vol Warnings | License & Ownership | Proprietary | Closed-Source | Proprietary | ✅ Open Source MIT | Getting started with Vacanam is completely frictionless: VacanamSetup.exe from Tip: Right-click the tray icon to customize your language, voice profile, or AI grammar rules .
