Online Dictation vs Offline Software: The Complete Comparison
The voice-to-text landscape has two main approaches: online browser-based tools (like ours) and offline downloadable software (like Dragon NaturallySpeaking). Both convert speech to text, but they do it very differently.
What Is Online Dictation?
Online dictation runs directly in your web browser. You open a webpage, click Start, and begin speaking. The audio is processed using the browser's Web Speech API (powered by Google's cloud speech recognition in Chrome/Edge). No downloads, no installations, no software updates to manage.
Examples: Our tool, Google Docs Voice Typing, Speechnotes, Dictation.io.
What Is Offline Dictation?
Offline dictation software is installed on your computer and processes audio locally without needing an internet connection. The speech recognition engine runs on your machine, using your CPU/RAM. Popular examples include Dragon NaturallySpeaking, Windows Speech Recognition, and macOS Dictation.
You download the software once, install it, and it works even when you're completely offline.
1. Setup & Convenience: Online Wins
Online dictation is instant. Open the webpage, click Start, speak. Zero setup time. If you're on a friend's computer, a library computer, or a new device, you can still use it immediately.
Offline software requires: Download (1-5 GB), installation (5-10 minutes), sometimes account creation, possible system configuration. If you switch computers, you must reinstall. For Dragon, you also need to pay $150-$300 per license.
Winner: Online dictation for speed and convenience.
2. Cost: Online Wins
Online dictation is almost always free. Our tool, Google Docs Voice Typing, Dictation.io—all free with no limitations on basic transcription.
Offline software costs money:
- Dragon Home: $150
- Dragon Professional: $300-$500
- Windows/macOS built-in: Free, but limited accuracy
If you're on a budget or just need occasional dictation, paying $150+ for offline software doesn't make sense.
Winner: Online dictation for cost.
3. Accuracy: Tie (with nuance)
Online dictation accuracy: 85-90% for clear audio with standard accents. Powered by Google's cloud speech recognition, which improves continuously as Google trains its models on billions of voice samples.
Offline software accuracy: Dragon claims 99% accuracy, but that's in ideal conditions after voice training. Realistically, most users get 85-95%. Windows/macOS built-in dictation is around 80-85%.
For most casual users, the accuracy difference is negligible. Dragon has an edge for medical/legal terminology (with specialized versions) and for users willing to train the software with their voice profile.
Winner: Slight edge to offline (Dragon) for specialized use, but online is competitive for general use.
4. Internet Requirement: Offline Wins
Online dictation requires internet. If your Wi-Fi goes down or you're in a remote area with no connection, browser-based tools stop working. Simple as that.
Offline software works anywhere. Plane, train, remote cabin—doesn't matter. As long as your computer has power, you can dictate.
If you frequently work offline (journalists in the field, writers in remote areas, travelers), offline software is essential.
Winner: Offline dictation for offline use (obviously).
5. Privacy & Security: Offline Wins
Online dictation sends audio to the cloud. When you speak into a browser-based tool, your audio is transmitted to Google's (or another provider's) servers for processing. While Google has strong privacy policies, your audio is technically handled by a third party.
Offline software processes everything locally. Your audio never leaves your computer. For lawyers transcribing confidential client notes, doctors recording patient information, or anyone handling sensitive data, this is critical.
That said, online tools like ours don't store your transcriptions—they're processed transiently and deleted immediately. But the audio still passes through cloud servers.
Winner: Offline dictation for maximum privacy.
6. Cross-Device Flexibility: Online Wins
Online dictation works on any device. Your Windows desktop, Mac laptop, iPad, Android phone, Chromebook—if it has a browser, it can dictate. You're not tied to one machine.
Offline software is device-locked. Buy Dragon for Windows? It works on that one Windows PC. Want to use it on your Mac too? Buy another license. Switching computers? Reinstall and reactivate.
Winner: Online dictation for flexibility.
7. Updates & Maintenance: Online Wins
Online tools update automatically. We improve the interface, add features, fix bugs—you get all updates instantly just by refreshing the page. Google improves speech recognition on their end, and you benefit immediately.
Offline software requires manual updates. Dragon releases a new version? You pay for the upgrade or stick with the old one. Windows Speech Recognition hasn't changed much in years. Updates mean downloads, reinstalls, potential compatibility issues.
Winner: Online dictation for hassle-free updates.
8. Storage & System Resources: Online Wins
Online dictation uses zero disk space. No installation files, no cached models, no temporary folders. Everything happens in the browser's memory and clears when you close the tab.
Offline software requires 1-5 GB of storage. Dragon takes up 4+ GB. If you're on a laptop with limited SSD space, that matters. Plus, offline software runs in the background, using CPU/RAM even when you're not dictating.
Winner: Online dictation for lightweight use.

Frequently Asked Questions
Can online dictation work offline?
No. Browser-based online dictation requires an internet connection because audio is processed in the cloud (Google's servers). If you need offline functionality, you must use downloadable software like Dragon or built-in OS dictation.
Is online dictation less accurate than offline?
Not significantly. Online tools (Google's Web Speech API) achieve 85-90% accuracy. Dragon (offline) claims 99% but realistically gets 85-95% after voice training. For most users, the difference is minimal. Dragon has an edge for specialized medical/legal vocabulary.
Is my audio stored when I use online dictation?
It depends on the tool. Our tool processes audio transiently—nothing is saved or stored after transcription. Google Docs may associate transcriptions with your Google account. Offline software never sends audio anywhere—it stays 100% local.
Why is offline software so expensive?
Offline software like Dragon requires years of development, custom speech recognition engines, and ongoing maintenance. You're buying a perpetual license for software that works without recurring cloud costs. Online tools are free because they use Google's cloud API, which Google provides at no cost to developers.
Can I use online dictation for sensitive documents?
Use caution. Online dictation sends audio to cloud servers. For highly confidential content (legal briefs, medical records, trade secrets), offline software is safer. For general emails, notes, and drafts, online tools are fine.
Does online dictation work on mobile devices?
Yes. Online dictation works in mobile browsers (Chrome on Android, Safari on iOS). Offline dictation software typically requires a desktop OS—Dragon is Windows/Mac only, not available on phones/tablets.
Which has better long-term cost?
Online dictation is free forever. Offline software has upfront cost ($150-$500) plus occasional upgrade fees. If you use dictation casually, online is cheaper. If you dictate 8 hours/day professionally, offline software's one-time cost becomes worth it.
Can I use both online and offline dictation?
Absolutely! Use online dictation (free, convenient) for 90% of your work, and keep offline software for specific cases (offline travel, sensitive documents, specialized terminology). They complement each other well.
