Turn scripts into studio-quality AI avatar videos in minutes
Choose from 500+ stock presenters, use photo avatars, or train a custom Video Avatar that looks and sounds like you, then generate narrated videos straight from a script.
Localize one recording into 175+ languages and dialects with editable scripts, brand glossaries, voice switching and proofreading seats for native-language review.
An agentic workflow expands ideas into finished videos, with access to leading generative models for video and image generation on higher plans.
Add quizzes, branching and decision points, embed videos by link, and export SCORM packages so content drops straight into corporate learning systems.

AI demo agent that runs your real product live for every visitor
Karumi operates your actual application rather than playing back a recording, so what prospects see always matches the current release and every demo counts as a functional walkthrough.
Visitors can speak, type, and interrupt in their own language, and the agent answers questions on the spot instead of forcing them into a form or a scheduled call.
Recordings, transcripts, questions asked, and suggested next steps are logged into your CRM, giving sales reps context before the first human conversation.
Screens, flows, and video clips are mapped continuously, then exposed via API and MCP so tools like Claude, ChatGPT, or Cursor can build agents and read journey data.
