We built the fastest explainer video generator in the world.

Introducing Simi: turn any prompt, doc, or idea into a complete whiteboard explainer video in seconds.

It supports 80+ languages, so the same idea can be taught to audiences anywhere.

AI video has gotten insanely good at cinematic clips.

But almost nothing can actually teach.

Most tools are built for shots, scenes, avatars, and ads.

Simi is built for explanation.

Give it something like:

“Explain backpropagation” “Teach photosynthesis” “Walk through our onboarding flow” “Turn this product doc into a video” Simi writes the script, creates the visuals, animates the sequence, adds narration, and renders the final video. Our fastest tier can generate videos in under 20 seconds. And you can one-shot long explainers over 15 minutes.

We’re starting with whiteboard explainers because they are the clearest way to teach complex ideas step by step.

But the bigger goal is simple:

Any knowledge should be instantly turnable into video.
