Software, made like furniture.
A one-person workshop building small, honest products: a tracker that writes up your game night, a reading log that shows you the whole spectrum, a solo RPG run by an AI game master, and free tools that tell you the truth about small data. Measured twice. Joined clean. No dark patterns.
Two products live, more on the bench. Everything here respects your data.
Craft over churn
Few products, made carefully, and finished. A joint you can see is a joint you can trust.
Measure twice
Built on real measurement and statistics, not vibes. The math is shown, not hidden.
Your data is yours
Export it, delete it, keep it on your device. No selling, no training on it, no tricks.
Five things on the bench
Each solves a specific, honest problem — some live today, some still taking shape.
Sits in on your game, transcribes it, and turns it into the after-work you never get to: the recap, a campaign wiki that writes itself, and a record of what was actually rolled — across your system, not just one.
Read about Six AxesA book log that does the ordinary things well — shelves, stats, streaks, clubs — and one thing nothing else does: it shows you the spectrum of voices across your reading, quietly and without judgment.
Read about LitmusDescribe your product; Shyll maps its market, finds the channels its real audience gathers in, drafts native copy, and sequences a growth playbook — and you correct it at every layer. The honest barker.
Read about ShyllYour table for one. Dream a world in your own words, make a hero, and play — the game master narrates, voices every NPC, rolls fair dice, and draws you the map. No table, no scheduling, no prep.
Read about QuestSoloOne event log, four views, for hobbyist manufacturing. Log every print, cut, and job; get honest job-costing and calibration that sharpens as your history grows. The moat is your own accumulated runs.
What's on the benchSmall, sharp tools — no signup
A set of free, client-side calculators that tell you the truth about small, noisy samples. They share one unit-tested statistical core. Your numbers never leave your browser.
Is my ad result real?
Bayesian A/B for small budgets — the probability one variant truly beats another, and a straight call. Safe to peek.
Is my survey valid?
Grade your questions for leading and loaded wording, then read your responses with honest confidence intervals.
Is my idea validated?
Weigh your evidence honestly — a stranger paying beats a friend's "cool idea" — with bias flags and a next step.
Will my drop sell?
Turn a landing-page smoke test into a projected paid conversion, folded into unit economics for a go / no-go.
One studio, one standard.
