Words should feel finished.
MumbleFlow is a voice workspace for the gap between what people say and what they actually need: writing that is ready to send, and meeting knowledge that is easy to trust, find, and act on.

MumbleFlow writes. Oat remembers.
MumbleFlow dictation
From speech to polished writing
Hold or lock Fn, speak with pauses and corrections, and receive final text with fillers, restarts, punctuation, paragraphs, and clearly introduced lists handled on device.
Explore dictation →Oat meeting notes
From conversation to cited action
Record by choice, follow a live speaker-separated transcript, catch up on the last five minutes, and leave with decisions, next steps, open questions, and links to the supporting moments.
Explore Oat →Why it is built this way
Fast, grounded, and under your control
Natural in
The interface should let people ramble, pause, correct themselves, and think aloud instead of learning dictation syntax.
Finished out
Cleanup should improve structure without silently changing names, numbers, links, substance, or intent.
Evidence attached
A generated meeting claim is useful only when a person can reach the source that supports it.
Recording by choice
There is no ambient buffer, automatic calendar start, or meeting bot. Capture begins after an explicit action.
Local intelligence
Customer speech, writing, summaries, embeddings, and meeting search stay on the Mac instead of feeding a hosted inference service.
Visible limits
Unavailable connectors, model requirements, retention rules, and uncertain speaker identity should be stated rather than hidden behind marketing copy.
Implementation
A native Apple Silicon application
MumbleFlow is written in Swift 6. SwiftUI powers the full workspace, while AppKit handles the global event layer, accessibility insertion, focus, floating panels, and Mac-specific capture behavior. ScreenCaptureKit records meeting audio without registering a video output.
FluidAudio supplies the on-device speech stack: Silero voice activity detection, English Parakeet TDT v2 recognition, and remote-speaker analysis. Apple's SystemLanguageModel is the preferred semantic engine; an optional Qwen3 1.7B model runs locally through MLX when Apple Intelligence is unavailable.

Questions
Frequently asked questions
Who makes MumbleFlow?
MumbleFlow is built by Aura Technologies LLC. Product questions and support requests can be sent to contact@aura-technologies.co.
What is Oat?
Oat is the meeting workspace inside MumbleFlow. It turns explicit meeting recordings into a timestamped transcript, speaker-aware catch-up, cited summaries, decisions, next steps, open questions, and searchable local knowledge.
Is MumbleFlow a browser extension or meeting bot?
No. It is a native Apple Silicon Mac application. Dictation works at the system level, and meetings are captured from selected computer audio and the microphone only after the user explicitly starts recording. No bot joins the call.
What technology does MumbleFlow use?
The app is written in Swift 6 with SwiftUI and AppKit. Its local speech stack uses FluidAudio, Silero VAD, and Parakeet TDT v2. Semantic writing and notes prefer Apple Foundation Models with an optional local Qwen3 fallback through MLX.
