What each tool does
Synthesia is a business video platform. You write a script and a lifelike AI avatar presents it, which suits training material, internal updates and learning content. It supports more than 160 languages, includes an AI assistant, and exports to an LMS or other video platforms. It is paid, with enterprise options.
Luma AI offers video generation and image creation powered by its own models, Ray and Uni. Its creative agents can run end-to-end workflows, from product hero shots to social ad variants and teasers. It is aimed at creative teams that need brand-matched content quickly, and it can be tried for free.
