Features
The AI email responder that keeps you in charge
Four tones, one click
Professional, Friendly, Direct or Detailed. Switch tone and the reply regenerates instantly.
Learns your style
Your approved replies shape the next ones: greetings, sign-off, length. See and reset what it learned anytime.
Any language
The reply always comes back in the language of the email — English, Italian, German, Japanese, whatever lands in your inbox.
Instruction files (Max)
Attach .md or .txt style guides and every AI email reply follows them. Company tone guide? Personal writing rules? Done.
Private by design
No account, no inbox access, no stored emails. MailReply only sees the text you select, when you ask it to.
Pricing
Two weekly plans. Try the demo first.
FAQ
Questions, answered
How is this different from Apple Intelligence or Gemini?
Those are locked to Apple Mail and Gmail, and their replies are short and generic. MailReply works in every app on your Mac, writes complete replies in four tones, follows your personal instructions and learns your style over time.
Does it work with Outlook / Gmail / my company's client?
Yes. MailReply isn't a plugin — it reads the text you select anywhere on macOS and pastes the reply back where your cursor is. If you can select and paste, it works.
Can I try it before paying?
Yes. The app includes a live demo on a sample email so you can see exactly how it works. To reply to your own emails you pick a plan — Pro at $3/week or Max at $5/week.
What languages are supported?
All of them — the reply is always written in the same language as the email you received.
Is my email stored anywhere?
No inbox access, no storage of your emails. Only the text you explicitly select is sent for generation. Replies you approve are used (privately, tied to your device) to personalize your future replies — you can view and reset this anytime in Settings.
