Simi

Simi (by Lamina Labs) is an AI explainer-video generator that turns raw source material — a PDF, Word doc, slide deck, or even a typed-out idea — into a clear, whiteboard-style animated video almost instantly, with no scripting, editing, or design work required. The pitch is speed and clarity: most AI video tools are slow and clunky, while Simi takes a document in and ships a finished explainer out in seconds, using a whiteboard aesthetic that keeps viewers watching instead of skimming text. It's aimed at students who need to compress dense material into digestible visuals, course creators and educators building lesson libraries at scale, and customer-training or enablement teams that need to turn product docs and SOPs into onboarding videos without a production pipeline. Because the output is generated directly from your source content, Simi is best understood as a document-to-video layer for explaining complex ideas fast — not a full video editor — making it a natural fit for anyone who values comprehension and turnaround time over fine-grained creative control.
