Resonant — Voice for email
You know what the email should say. You know the tone, the structure, the key points. The only thing between you and “sent” is the time it takes to type it. Resonant removes that.
Press a hotkey in Gmail, Outlook, Apple Mail, or any webmail. Speak your reply. Clean, well-structured text lands in the compose window. Processed locally on your Mac.
The problem
Quick replies are easy. The emails that sit in your draft folder are the ones that require nuance — the client update, the difficult feedback, the strategic recommendation, the message where tone matters.
These emails take 10-15 minutes to type because you're not just communicating — you're crafting. Choosing words. Rewriting sentences. Adjusting tone.
But you could say the same email in 30 seconds. The spoken version has the right tone, the right emphasis, the right level of directness. It just needs to be captured.

Client follow-up after a discovery call
“hey so great talking to you today, the main thing I took away is that the integration timeline is the biggest concern, I think we can address that by running the technical setup in parallel with the legal review instead of sequentially, that would save about three weeks, I'll put together a revised timeline and send it over by Friday along with the SOW changes we discussed”
Great speaking with you today. The biggest takeaway was the integration timeline concern. I think we can address this by running the technical setup in parallel with the legal review instead of sequentially — that saves roughly three weeks. I'll send a revised timeline and updated SOW by Friday.
Internal escalation to leadership
“I want to flag something before the planning meeting, the migration work is going to take longer than the two sprints we allocated mainly because the legacy data has inconsistencies we didn't account for in the estimate, I think we either need to cut the search feature from Q3 or bring in a contractor for the migration, happy to walk through the tradeoffs”
Flagging ahead of the planning meeting: the migration work will exceed the two-sprint estimate. Root cause is legacy data inconsistencies we didn't account for. Two options: (1) cut the search feature from Q3 scope, or (2) bring in a contractor for the migration. Happy to walk through the tradeoffs whenever you have time.
Thoughtful reply to a direct report
“thanks for sharing that, I appreciate you being direct about it, I think your instinct is right that the project scope has grown beyond what we originally planned and it's not fair to hold you to the original timeline given the additions, let me talk to Sarah about either trimming the scope back or extending the deadline, either way I don't want you feeling like the goalposts moved without the support changing too”
Thanks for sharing that — I appreciate the directness. Your instinct is right: the scope has grown beyond the original plan, and holding you to the original timeline given the additions isn't fair. Let me talk to Sarah about either trimming the scope or extending the deadline. Either way, the goalposts shouldn't move without the support changing too.

Tone
Resonant adapts the tone to the context. A client email gets polished and professional. An internal reply stays direct and conversational. The output sounds like you — at your best — not like a template.
No “I hope this message finds you well.” No corporate padding. Just clear communication with the right level of formality for the audience.
Privacy
Cloud dictation tools process your audio on external servers. Sensitive email content — compensation discussions, legal matters, personnel decisions — creates a record on infrastructure you don't control.
Resonant processes audio on your Mac. Only the finished text reaches your email client, through normal input. No audio transmitted. No vendor with access to your correspondence.
Free. Local. Works in every email client.
Every email you've been putting off takes 30 seconds to dictate. No subscription. No cloud. Just a hotkey.
