The core difference
Grammarly works after you type. It watches your keystrokes and underlines grammar errors, suggesting inline corrections. It's polishing text you've already written.
AiType works before you type. You speak, and AiType produces clean, paste-ready text in ~250ms. There's no typing and no correcting — you go from thought to finished text in one step.
They're complementary tools, not substitutes. But if your main bottleneck is the time it takes to get words on screen — not just correcting them after — AiType addresses the root cause.

Use AiType when…
- You want to bypass typing entirely. Voice-to-clean-text in under a second.
- You're dyslexic or have RSI / carpal tunnel. AiType removes the keyboard from the equation.
- You write on Windows and need a consistent keyboard and dictation experience.
- You process a high volume of short messages — Slack replies, emails, WhatsApp — and want to speak them instead of type them.
- You're a developer who dictates prompts into Cursor, Codex, or other AI tools.
Use Grammarly when…
- You write formal documents that need grammar, plagiarism, and tone checks after the fact.
- You manage a team's writing quality and need a consistent style guide enforced across writers.
- You're editing text written by others rather than producing your own.
- You prefer inline corrections while typing rather than a speak-first workflow.
Can you use both?
Yes — and many people do. Speak your first draft into AiType, paste it, then run Grammarly over it for a final polish pass. AiType handles the 80% that's about capturing the idea quickly; Grammarly catches the remaining grammar edge cases. Together they cover the full pipeline from thought to polished document.
Bottom line
Grammarly is a post-typing editing tool. AiType replaces the typing step entirely. If you're spending time typing first drafts that you then have to fix, AiType solves the problem further upstream — and is cheaper.
