Market Opportunity
Strict Roman-numeral parsing + explainable step-by-step breakdown targets a $8.4B = 25M software developers x $336 ARPU (annual developer-tools + small utilities spend) total addressable market with medium saturation and a year-over-year growth rate of 8-12% — steady growth in developer tools, edtech, and API-first utilities.
Key trends driving demand: LLM explainability -- LLMs can generate polished, stepwise explanations for deterministic conversions, improving teaching and debuggability.; API-first microservices -- Teams prefer small, composable validation APIs they can embed across apps and forms.; EdTech focus on explainability -- Educators are demanding tools that show reasoning steps, not just answers.; Input hygiene & compliance -- More apps require strict, auditable validation to reduce downstream data errors..
Key competitors include npm open-source roman-numerals packages (e.g., 'roman-numerals', 'romannumeral'), Wolfram|Alpha, RapidTables / Online converter sites (e.g., RapidTables Roman Numeral Converter, CalculatorSoup), Google Search / Stack Overflow (workarounds).
