What is the best AI for dictating emails?

The best AI for dictating emails is one that lives in your keyboard and finishes the text as you speak: fillers removed, grammar corrected, greeting and paragraphs formatted, ready to send in Gmail, Outlook, or any mail app.

The built-in options, Outlook's Dictate, phone keyboard mics, transcribe accurately but type your words raw, so every email needs an editing pass. General assistants like ChatGPT write email well from typed prompts but cannot type into your mail client.

The best AI for emails overall depends on the bottleneck: composing from scratch favors a writing assistant; getting your own words out fast favors AI dictation. For most reply-heavy inboxes, dictation wins on volume.

Try the keyboard route with email dictation and watch a reply write itself.
