OVERVIEW Statistically honest analytics without a warehouse: paste a CSV or a list of numbers and get real answers — typed profiles, significance tests with plain-language verdicts, correlation, and growth math. Every method is deterministic and states its own caveats.

KEY CAPABILITIES • csv_profile — types, nulls, stats, duplicate and ID detection • ab_test — two-proportion z-test with a plain-language verdict • correlation — Pearson r with honest interpretation • growth_rates — period growth + CAGR • Licence: funnel_report (biggest drop-off first), cohort_retention (plateau detection), forecast_trend (with R² caveats)

USE CASES • Sanity-check an experiment result before announcing a winner • Profile an unfamiliar CSV in one call before analysis • Turn raw signup numbers into a retention read your team can act on

WHO THIS IS FOR Founders, PMs, and analysts who need trustworthy quick answers — and agent builders who want real statistics instead of hallucinated math.

WHY MOLTLINE • Every tool tested against known answers before release • One All-Access licence ($19/month, settled in cryptocurrency through NOWPayments) unlocks the premium tools on every Moltline server - send it in the X-Moltline-License header • Support: first response <24h, confirmed defects fixed <30 days
