Echo Compass measures the alignment between a message you've written and the language of the market you're addressing. Seven dimensions of fit — vocabulary, register, emotion, cognitive frame, value drivers, specificity, and rhetorical risk markers — drawn from validated psycholinguistic research and applied marketing science.
What this tool is. Echo Compass measures linguistic and rhetorical alignment between a message you wrote and an aggregated body of market text. The seven dimensions — vocabulary overlap, register match, emotional resonance, cognitive frame, value drivers, specificity, risk markers — come from validated psycholinguistic and marketing-science traditions: Pennebaker LIWC, Schwartz value theory, Plutchik emotions, classical rhetorical analysis.
What this tool is not. Not a guarantee of campaign performance. Not a substitute for A/B testing, focus groups, or audience research. Not an individual-profiling tool — the market input must be an aggregate; using identifiable individuals as the "market" would defeat the design intent and create ethical concerns. Linguistic fit is a meaningful predictor of resonance, but markets are governed by far more than language: timing, channel, trust, distribution, competition, price.
How to read the scores. Treat the overall Fit Score and dimensional scores as directional diagnostics, not pass/fail verdicts. A high score doesn't mean your message will succeed; it means your message speaks the market's language. A low score doesn't mean the message is wrong; it may mean you are intentionally positioning against the prevailing register (sometimes a winning strategy). Use scores to provoke decisions, not to replace decisions.
Quality of input shapes quality of output. A weak market sample (too small, too narrow, biased toward one source) will produce an unreliable benchmark. The minimum useful market sample is ~500 words drawn from at least 3-5 distinct public sources. The minimum useful message is ~50 words. The tool will warn you when inputs fall below useful thresholds.
Ethical use. Echo Compass is designed for marketers, strategists, content writers, and researchers analyzing their own messages against public market language. It is not designed for, and should not be used for, profiling individuals, analyzing private communications without consent, or any application targeting identifiable persons. The "market" input must be public, aggregated material.
