Provides an ML-powered short-form video SDK that enables consumer apps and publishers to embed TikTok-style vertical video feeds with adaptive streaming, AI captioning, auto moderation, and built-in analytics.
Shortkit has publicly launched its core SDK supporting iOS, Android, and Web with feed-aware playback, adaptive bitrate streaming, next-gen codec support, AI-powered captioning in 50+ languages, automated content moderation, in-feed analytics, native ad integrations, and AI tools to convert long-form video into short-form clips. They reference Glassdoor, DoorDash, and CNN launching their own video feeds as evidence of market demand.
Two-person team heads-down on core infrastructure. Absence of public customer logos implies early design-partner phase. Conference and community signals point toward deeper ML investment in recommendation-driven feed personalization.
ML models dynamically pre-fetch and pre-buffer upcoming videos based on user swipe patterns and real-time network conditions, delivering instant playback with minimal data waste.
The app figures out which video you'll swipe to next and secretly loads it before you get there, so it plays instantly.
It's like a waiter who already knows your next order and has it plated before you even wave them over.
Automated AI captioning in 50+ languages and intelligent long-form-to-short-form video conversion reduce creator effort and expand global reach for every app using the SDK.
The SDK automatically writes subtitles in dozens of languages and chops long videos into the best short clips—so creators don't have to.
It's like having a multilingual editor who watches every video, writes perfect subtitles, and picks the highlight reel—all before your coffee gets cold.
ML-based auto-moderation scans every uploaded video for policy violations across visual, audio, and text signals, keeping feeds safe without manual review queues.
Every video uploaded through the SDK gets automatically screened for harmful content so app teams don't need a room full of human moderators.
It's like a bouncer at the door of every video feed who never sleeps, never blinks, and gets smarter every shift.
