Frequently asked questions

What is Vivacity?

Near-real-time video infrastructure for LLMs. It turns prompts, documents, and AI answers into narrated, mathematically exact explainer videos you can call from an app or agent.

How is this different from whiteboard AI video?

Whiteboard tools optimize for fast drawn explainers. Vivacity optimizes for coordinated, mathematically exact diagrams. Equation morphs, graphs, spatial proofs. When the visual has to be correct.

What can I feed it?

A plain prompt, a document, or an upstream model answer. Any topic works. Math and science are where precision shows most.

How fast and how cheap?

Near real-time on short clips. Careful short renders land around ₹7 / about $0.08. Designed so EdTech chatbots and agents can afford volume.

Languages?

English, Hindi, and Hinglish narration today, with more language paths on the roadmap.

Is there an API?

Yes. Submit a job, poll status, receive a video_url. Built so products and agents can embed generation without owning a render farm.

Who is this for?

EdTech platforms, LLM apps, creator pipelines, and anyone replacing text dumps with motion that teaches.
