Apps, projects, companies, that sort of thing.

Séisionnach LLC

JigRipper

Mobile and web app

jigripper.comGoogle PlayApple App Store

A neural tune identifier for the Irish traditional corpus.

It remembers every tune played over the course of a night — whatever the instrument, whatever the key — and links each one to its setting on TheSession.org. It will also tell you who is in the mix: pipes, fiddle, flute, box.

The models run on the device, browser included, with no internet connection. The audio never leaves the device.

AirHog

Watch and phone app

Your own in-ear monitor mix, adjusted from your wrist, mid-tune.

AirHog speaks OSC over UDP straight to a Behringer X Air console — XR18, X18, XR16, XR12 — so a musician can change what they hear without turning round and asking for it. You get direct access to IEM mix channels direct from the watch.

Pick the main mix and every fader shapes what the room hears; pick a performer's monitor mix and the same faders move only their in-ears. Feedback protection notches out ringing where it hears it, and anything it does can be undone.

cytotype

Browser app

msolters.github.io/cytotypegithub.com/msolters/cytotype

Auditable cell-type annotation, in your browser.

Drop in a single-cell RNA-seq .h5ad and every cell comes back with a predicted type — and the marker-gene evidence behind the call. Not “the model said so”, but “these four genes co-fired, and that tuple is associated with cell type X”.

Live.

cairn

Browser app and CLI

cairn.marksolters.com

A retirement and net-worth tracker that never phones home.

Cairn provides a holistic financial snapshot tracker and hypothetical situation analyzer. Model future purchases, trades or windfalls. Visualize long-term impact on net worth based on decisions happening today, tomorrow, or in five years.

Cairn adheres to a strong privacy stance — your data is never sent to a server — purely on-device.

token-engine

Local tool

github.com/msolters/token-engine

Claude Code's realtime token throughput, synthesized as an engine note.

It tails Claude Code’s session transcripts and streams realtime token bursts to a browser tachometer that synthesizes the engine sound in real time.

Sustained heavy token usage accelerates through the gears. A one-line answer is a throttle blip. Silence decays to a lopey idle.

Runs locally — there is nothing to host.
