Users of the Captions platform can automatically add captions to existing videos, create finished videos from raw footage, adjust noise levels and eye contact of people onscreen, or create an entirely AI-generated video based solely on a text prompt. The platform has been used by more than 20 million users to create more than 250 million videos, the company said.
A Crowded Field
AI-driven video editing and generation is a crowded market. Mirage competes directly with UK-based Synthesia, which in February 2026 raised USD 200m at a USD 4bn valuation. Other competitors include HeyGen, ByteDance’s CapCut, Canva, and platform-native AI dubbing and captions features from YouTube and Meta. To stand out from the competition, Mirage is moving beyond basic video editing and into the development of full-stack foundational models for video.
Mirage plans to use the new funds on “expanding further into agentic video editing” and to expand in new markets, particularly Asia, where the company says “demand has been extraordinary and the opportunity is enormous.”
Video in 40 Languages
Mirage touts the localization use-case of its platform, where videos can be automatically subtitled into over 40 languages, dubbed into a new language with AI lip-syncing, and scenes or speaker appearances can be automatically changed based on the needs of different markets. Based on the company’s description of its translation capabilities, translation is done entirely by AI, and they tell customers, “you’ll want to do a final check to make sure you’re happy with the final audio.”
The Captions app has a free version with basic features and offers subscriptions ranging from $9.99 a month to $279.99 a month. The company also offers an enterprise tier for larger corporate clients.
