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.

Set up, launch and reproduce ML experiments with templatized configs and AI.
llog turns YAML configs and argparse code into guided, visual templates so experiments are reproducible by default.
Modify experiment parameters visually in a web GUI instead of editing files by hand, and add a new parameter across an entire pipeline in one click.
Visualise experiment outputs without writing code, and ask the AI questions to plot features in your data.
Launch and run experiments on your own server or through SLURM, with version control so runs can be reproduced.
