Teams that need to explain ideas, such as trainers, teachers, onboarding staff, and creators, often have the source material (a doc, deck, or script) but no fast way to turn it into a video. Doing this today means hiring a studio, manually scripting and animating, or booking calls to walk people through material one at a time. The page's own comparison shows alternative AI tools taking 9 to 20 minutes and costing far more to produce a single one-minute video, implying that existing options are slow and expensive for routine explainer content like SOPs, lessons, or product walkthroughs.

Simi takes a PDF, Word doc, PowerPoint, Markdown file, plain text, or a simple prompt and generates a narrated, scene-by-scene whiteboard explainer video. The page states it can produce a one-minute video in about 40 seconds, compared to 9 to 20 minutes for the named alternatives shown in its benchmark comparison (Claude Fable 5, GPT-5.5 Pro, NotebookLM). It supports 80+ languages for both source input and narrated output, offers videos up to about five minutes on standard plans, and provides an HTTP API, Python and Node SDKs, and an MCP server so agents can generate video programmatically. Pricing is credit-based (roughly one credit per second of video) across Plus, Pro, and Max monthly or annual plans, with a separate Business tier for branding, custom voice, higher limits, and commercial usage rights.
