Flitto is a platform that provides crowd intelligence translation services in collaboration with our 10.3 million users around the world. Using this platform, we collect and provide a huge multilingual corpus of language expressions used by native speakers of the region, and voice and handwriting image data as well. By using our collective intelligence platform, we quickly build large amounts of language data and efficiently manage it with our accumulated experience and knowledge. We tag the collected data with metadata (e.g. gender, age, locations, etc.) and provide it to customers.
