# Duckling (`duckling`)

Open-source (BSD) Haskell library from Meta that parses text in many languages into structured values called dimensions. The dimensions are amount of money, credit card number, distance, duration, email, numeral, ordinal, phone number, quantity, temperature, time, URL and volume. It extracts and normalizes values found in free text, such as turning a spoken amount or date into a number or a timestamp. The supported types cover only registry datatypes that match a documented type.
