"ugh okay so I need to email my landlord about the heat being broken again, like it's been three days and I just... I don't know how to say it without sounding annoying but also I'm freezing"
Living without heat for three consecutive days is not a minor inconvenience — it's a habitability issue. Tenants have a reasonable right to expect functioning climate systems, and repeated failures signal a maintenance problem that deserves prompt attention. Clear, documented communication is the first step toward resolution.

The problem with cloud transcription
You spend hours typing emails that could be spoken in minutes. Most people speak 3x faster than they type.
Typing long, thoughtful emails is draining. Speaking them feels natural and the ideas flow better.
Built-in dictation (Siri, Google) is inaccurate and doesn't format your text. You end up editing more than you saved.
Mumbl works in Gmail, Outlook, Apple Mail, any email client. Click compose, hit the hotkey, speak. Polished text appears.
Your voice never leaves your device
Mumbl processes everything locally using Whisper AI. No cloud uploads. No servers. No data collection. Your words stay yours.

Does it work with Gmail?
Yes. Mumbl works with Gmail, Outlook, Apple Mail, Yahoo Mail, or any email client. It pastes text wherever your cursor is. Open compose, hit the hotkey, speak, done.
