Building useful software, AI products, and experiments.
RismanLabs is an independent software lab. It designs, builds, and runs focused products and practical AI tools, end to end.
Products and experiments
Each one is built as a whole thing: its own name, its own repository, and its own address under rismanlabs.com.

Featured product
DuoDue
Simple debt tracking for two people.
A focused ledger for couples who lend to each other, split costs, and pay each other back. Every entry is agreed by both of you, so the balance is a shared fact instead of a running argument.
- One balance you can both see
- Debts and repayments roll into a single figure that is current for both of you.
- Nothing counts until you both agree
- An entry joins the balance only once the other person confirms it.
- Built for two, on purpose
- No groups and no splitting a bill five ways. It does one relationship well.

How the lab builds
Four commitments every product here is held to, from the first commit to the last deploy.
Clean architecture
Boundaries are drawn around the domain, not the framework, so a product can change its mind without a rewrite.
Performance
Rendered on the server, measured before release, and held to a budget rather than tuned after complaints.
Developer experience
Typed end to end, tested at the seams, and dull to deploy. Code the next person can read on the first pass.
Practical AI
Models go where they remove real work for the person using the product, and nowhere they would only decorate it.
