Nymfarious
Software you can trust.
A small studio making honest software for the projects that actually matter to you — your family history, your travels, your memories. AI does the surfacing. You keep the judgment, and the data.
The Workshop
What we're building
Some of these are live. Some are still on the bench. We will tell you which is which — no fake launch dates.
RootsDjinn Field Guide
The pocket companion to RootsDjinn — carry a branch, fan out your ancestors like a folding scissor-chart, capture finds in the field, and set out on gamified Expeditions, with every discovery returning safely to the desktop tree.
Best on mobile — the desktop layout may look skewed.
Launch Field Guide →TeaMark
Scan a china or glass backstamp and know the piece in 30 seconds — maker, era, pattern, and value. A forensic field tool for thrift-shop hunters and collectors, built for the moment the cup is in your hand.
In the workshopTopology Explorer
Six interactive demos — Möbius strips, Klein bottles, dimensional slicing, and prime constellations — you can drag, zoom, and reshape. Pure 2D canvas, zero WebGL, from hexagons to the 4th dimension.
Open Explorer →Parallax Debater
Two AI voices take opposite sides of a question and argue it out, so you can weigh the strongest case for each before you decide — structured disagreement as a thinking tool. (Placeholder pitch — confirm the real one.)
Coming soonTripSafe
Travel safety maps with risk-zone overlays and a "download this region" mode that works when you are off-grid. Built on open map data, sharp where it counts.
Coming soonAtlas Lab
Deep-zoom historical maps where borders move and place names change with the years — so a town that no longer exists is still findable, and an ancestor's journey can be drawn across the right century.
In the workshopLittle Sister
A gentle companion for friends and family walking alongside someone living with dementia, Alzheimer's, or other forms of cognitive change. Voice, photographs, and the family tree woven together — so the people who love them can stay connected, even on the hard days.
On HoldWhy we build this way
Honesty is not a feature. It is the point.
Most software makes promises that hide what is really happening. We do the opposite.
Data is always yours alone
Data is always yours alone
Portable exports on a schedule, one click, no support ticket. If we ever close, your work is already in your hands.
AI assists, you decide
AI assists, you decide
The model surfaces patterns and flags conflicts, then hands the call back to you. It is a research assistant, not an oracle.
Honest by default
Honest by default
Plain-English terms. We tell you when AI is used and what it sees. We tell you when a service might not last forever.
Small audience on purpose
Small audience on purpose
We build for ourselves and the small circle of people who think like we do. If we would not use it, we will not ship it. Growth for its own sake makes software no one wants.
