Human Atlas maps body-feeling idioms across 21 languages to sourced medical signals

A web tool called Human Atlas allows users to type colloquial body-feeling expressions in multiple languages — such as the Portuguese 'frio na barriga' or German 'Schmetterlinge im Bauch' — and receive the same ranked, sourced medical information as the equivalent English phrase 'butterflies in my stomach'. The platform currently covers 89 phrases across 21 languages, linking to 11 distinct body signals, with every phrase traced to a specific Wiktionary entry revision as its source. Each idiom functions only as a named alias for an existing signal and cannot create new causes or remove medical red flags, which remain visible regardless of the language used to search. Red-flag warnings have been translated into Portuguese, Polish, German, French, Spanish, Italian, and Dutch, though these have not yet been reviewed by native speakers. The developer reviewed major symptom checkers and medical databases and found no existing tool that treats everyday idioms as sourced aliases of body signals while also displaying cross-language equivalents with dictionary citations.
