Vibe Typer: Voice‑First Writing and Editing

Vibe Typer is more than dictation - it's a voice-first writing assistant. Speak and your words appear in your current application, from code editors to email clients. If you highlight text and say "rewrite", Vibe Typer can improve grammar, adjust tone, or simplify wording. When responding to an email or chat, copy the conversation to the clipboard and say "reply" to draft a context-aware response.

Use Vibe Typer if: you think faster than you type and want to capture ideas hands‑free. It’s great for remote workers, programmers, researchers, and anyone who needs to write quickly while multitasking. AI rewrite and reply features make it easy for non‑native speakers to polish their messages.

Speed Test Comparison
