Any topic in.
Whiteboard video out.
Boardcast writes the script, voices it, and draws it by hand, one idea at a time. Each sentence draws exactly what it talks about. Type a topic or upload a PDF, DOCX or slides. Use your own key from any LLM provider.
Works with Claude, GPT, Gemini, Mistral, OpenRouter, Groq, Together, DeepSeek, Ollama and LM Studio.
Live preview (silent here). The renderer behind it produces 1080p MP4 with narration and captions.
Describe it
A topic, a prompt, or a document. Pick the length, audience, language, voice and board style.

See every beat and sentence. Swap drawings, rewrite lines, regenerate one beat, and preview instantly.
Render

Your keys stay yours
API keys are encrypted with AES-256-GCM, decrypted only inside the render worker for your job, never logged and never shown again (only the last 4 characters). Delete them any time.
