Mumble Note is an AI voice note-taker designed to be the fastest way to capture your scattered thoughts, and turn them into organized notes. You can speak, type or do them both. AI will combine your inputs together and generate structured, actionable and easy-to-retrieve notes for you.

Our users have been using Mumble Note for quick idea capture, voice journaling, meeting notes, and so much more.

Mumble Note transforms casual, freeform spoken thoughts into structured and functional notes. Users can talk freely to input ideas, thoughts, to-dos, or memories, which are instantaneously transformed into organized notes by the AI. It also allows users to add images from both within the app and other applications, and subsequently take voice notes on them. It can generate images covers, create to-do lists, ask AI to rewrite or translate notes, and allow users to use voice edit to make changes as they need.

Mumble Note is available on iPhone, Apple Watch and Mac (Beta) now.

Acuity Scheduling alternatives for businesses outgrowing it
The honest read: if you're leaving Acuity because your business outgrew simple scheduling — you need deposits, add-ons, multiple staff and locations, and ideally a booking site you own — Opencals is built for exactly that transition, and pay-as-you-go means it costs nothing until you're earning. If you're leaving for a narrower reason, match it precisely: SimplyBook.me for...

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

    The App I Didn’t Know I Needed

    I started using Mumble Note casually, thinking it was just another voice memo app. Now I'm using it everyday. Whether I’m in the car, walking, or too lazy to type, I just talk, and it does the rest. If you ever have thoughts you don’t want to lose, this is the app to get.

    Pros:    Sync across all my devices|Easy to use

    I've been using Mumble Note for months

    Sometimes my ideas come and go in a flash. For me typing feels too slow, and relying on memory is risky. Mumble Note just gets me! Capturing ideas has never felt this natural and I've been using it as the 1st steps in my journaling and writing workflow.

    Pros:    Super fast|Accuracy|Well designed

  • AI Almost Sold Me a Subscription I Didn't Need
    I keep coming back to what would have happened if I didn't have a strong technical understanding of how calendar technology works — the difference between local and cloud calendars, what an ICS feed is, why enterprise auth blocks third-party integrations. If this was many years ago before I gained all this experience, I would have stopped at the first confident answer from my search tool, installed one of those... - Source: dev.to / 6 months ago
