The design canvas built for AI coding agents
Generate complete, multi-screen interfaces from a text prompt, PRD, screenshot or pasted product URL rather than a single static screen.
Every design maps directly to code, so you can preview interactive prototypes quickly or export and ship the implementation.
Iterate by asking the AI for changes, or click any element and edit it by hand — the two modes work on the same file.
Connect Cursor, Claude Code, Windsurf or Codex so agents can generate screens and edit designs inside your editor.

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.
