stetterio

A one-person technology accessibility studio

Accessibility is an engineering problem.

Stetter.io builds apps, guides, and AI tooling that close the gap between what technology promises and what people with disabilities actually get. Everything here is dogfooded, mostly out of necessity.

What we build

  • Apps

    An MS symptom and event tracker, built for fast logging during a bad day. Mood, symptoms, and what helped, captured in seconds. Self-hosted backend. Your data stays yours.

  • Guides

    The MS Wellness Guide. Plain-language and practical. Written for people managing real life, not reading medical journals.

  • Local AI that works for you

    Hermes Desktop running open models on hardware in my house, wired into my health records. Ask plain-English questions about your own chart, draft clear messages to your care team, and keep track of what was said. The chart never leaves the building.

    It also works with hosted assistants like Claude, but then your chart is in someone else’s cloud. Local is the default here.

    Same approach at home: MCP servers that run a homelab or smart home when you ask for what you want.

  • Accessible home

    Home Assistant automations, like music that follows you from room to room using presence sensors. Automation as accessibility, not novelty.

Case study

How we replaced a 20-minute portal login with one sentence.

Before: log in, find the right menu, scroll years of results, squint. After: ask the question in plain English. A local model answers from a read-only copy of the chart, with dates and sources. Nothing leaves the house.

Full write-up coming.

How we work

Built by a user.
Every feature exists because something annoyed me this week.
Self-hosted and local-first.
Health data is not a growth metric. It runs on hardware I control, and AI runs locally where it can.
Boring infrastructure.
Minimal, purposeful, GitOps. Fewer moving parts means fewer things that fail when you can’t spare the energy to fix them.
Accessible by default.
This site holds itself to the same standard it preaches.

About

18 years in DevOps and software architecture, building infrastructure that had to stay up. Then multiple sclerosis made the gaps in everyday technology personal.

Same instincts, new problem: if a system is hard to use, that’s a bug, not a user error. Stetter.io is where those fixes live.

Pricing

Free. It’s a hobby with a domain name.
