Hey Product Hunt! I'm Brock, the maker of Mumbl.
I built this because I was tired of typing out long emails when I could just say what I meant in 10 seconds.
The problem with every other voice to text tool? They send your audio to the cloud.
If you're a lawyer drafting client notes or a financial advisor writing investment memos, that's a dealbreaker.
Mumbl keeps everything 100% on your device using local Whisper AI. No cloud, no data collection, nothing leaves your machine.
I'd love your feedback, what would make this useful for your workflow?

Love the positioning here. On-device processing is such an underrated advantage especially for lawyers, advisors, and compliance-heavy teams.
Have you seen more traction from individual professionals or small firms so far?

@vichognza Mostly from individuals at the moment but you are right!

I have personally been using this and me specifically I have been using it for coding.
And what I mean by that is I use it to enter prompts for AI. I can give context and explain/correct what I’m wanting to do way faster than I can type it and it has been soo good.
This is great! I know some people who are really impeded by not being able to type. This could help people with physical disabilities and people who just haven't learned how to type.
Way to be a forward thinker!

@paula_lozano_gonzalo I love it. I use it personally all day with claude code
Obsessed with this concept!
As a founder, I’m constantly voice-noting ideas faster than I can type them… but the privacy part always makes me hesitate.
The fact that it’s 100% on-device?? That’s actually so smart.
Definitely want to try this for emails and brain-dump sessions
Congrats on the launch!!
@avery_weir Thank you! We hope you love it!!
