Cinnamon

Cinnamon (株式会社シナモン) is a Tokyo-based company that builds AI tools for processing enterprise documents. Its Flax Scanner product uses AI-OCR to extract data from documents in varied formats and layouts without requiring a template to be set up in advance, using a mix of coordinate-based, feature-learning, and generative AI extraction methods that the system selects between automatically depending on the document. A related product, Super RAG, lets employees search and get answers from a company's internal documents, including ones with tables, charts, and handwritten content, aiming to keep hallucinated answers to a minimum. Cinnamon targets large enterprises in finance, insurance, logistics, and manufacturing that handle high volumes of paperwork such as invoices and internal reports, and its client list includes major Japanese companies like Toyota, Fujitsu, and Daikin. The company positions its offering as reducing the cost and effort of setting up document automation, describing its approach as automating the automation process itself rather than requiring a lengthy setup for every new document type. Cinnamon's marketing and product documentation are primarily in Japanese, and while an English-language version of the site exists, most detail is written for a Japanese enterprise audience, so evaluating fit outside Japan may require more direct contact with the company.
