KaraVideo is an AI video generation platform that launched in beta around October 2025, built inside the research labs of AI Secret, an AI-focused newsletter read by an audience the company puts at 1.7 million subscribers. A small internal team spent two months connecting private APIs from multiple video-generation vendors before opening the first beta to AI Secret's subscriber base.
Rather than building its own video model, KaraVideo aggregates access to leading third-party engines, including Sora, Kling, Veo, Runway, and Pika, behind a single prompt box and one unified credit balance, so a user is not juggling five separate subscriptions and interfaces to compare outputs across models. Users can generate from text, from an uploaded image, or from an existing video clip, and the platform bills only for seconds of video actually rendered rather than a flat per-generation fee.
KaraVideo suits creators and marketers who want to compare or mix outputs from multiple leading video models without subscribing to each one directly. The free plan includes 50 credits (about 2 videos) with 1 parallel task; paid plans move from Lite at $15 per month (500 credits, up to 50 videos, 3 parallel tasks) up to Pro at $35 per month for 1,250 credits and 5 parallel tasks.
