Murmr
Voice notes, cleaned up on-device
Murmr captures your voice, refines the transcript on-device, and turns it into ready-to-use structured output for stand-ups, issues, and drafts.

Why I'm building Murmr
Murmr exists because I want to see how far I can push a local, offline workflow on Apple platforms. Voice is the fastest way I know to capture ideas, but the next step shouldn't require shipping your thoughts to the cloud.
Murmr is a small tool with a clear goal: capture a thought, clean it up, and turn it into something you can act on. The ambition is to keep that loop local-first: low latency, private by default, and resilient when you're offline.
A raw transcript is rarely the end product. Most of the time I want a structured result: a stand-up update, an issue with context, a rough outline for a doc, or a cleaned-up draft. Murmr is built around those outcomes, with templates and constraints so the output stays consistent and useful.
The deeper motivation is stepping away from the default “cloud AI for everything” approach. If a task can be done on-device, it should be. That has practical benefits: lower ongoing cost, less dependency on external services, and a smaller environmental footprint. It also avoids the thing everyone is tired of: another subscription for something that should feel like a basic utility.
What it does
Fast capture
Record voice notes with minimal friction, designed for the moments when typing is slower than thinking.
Offline-first by design
Useful without a network connection. The goal is to do as much as possible locally, and avoid cloud AI when you don’t need it.
Structured outputs
Convert notes into useful formats like stand-ups, issues, and draft-ready writing prompts.
On-device intelligence
Exploring what’s possible with Apple’s on-device models and local inference, with privacy and latency treated as first-class constraints.
Templates that stay consistent
Use repeatable formats so the output stays predictable, reviewable, and easy to reuse in real work.
Less cloud, fewer subscriptions
Reduce recurring costs and avoid yet another subscription by keeping the core workflow local-first.
Who it's for
Murmr is for people who think out loud: developers, product folks, writers, and anyone who gets their best ideas away from a keyboard. If you've got a backlog full of half-notes and half-drafts, it's built to turn that mess into something you can ship.
It's also for anyone who wants a voice workflow without the “upload everything” default. Notes are often sensitive. Murmr is designed to be useful even when you're offline, and to keep ownership and control in the foreground.
In progress
Murmr is actively iterating in TestFlight. The goal is simple: capture, clean up, and format voice notes into outputs you'll actually reuse in day-to-day work.
