SlideNebula

Drop your deck onto the canvas

.pptx, images, videos, PDFs, Word docs, XML, JSON, or Markdown — parsed right in your browser, nothing uploaded to a server

Your slides become floating cards you can arrange and connect

AI analysis

Connect any OpenAI-compatible model to analyze cards or the whole board (Board advisor). Claude works via a gateway such as OpenRouter or a local proxy — point Base URL at that endpoint and set the Claude model name. Keys stay in this browser — SlideNebula has no server.

Any OpenAI-compatible endpoint works — OpenRouter (for Claude and others), a hosted provider, or local models via Ollama (http://localhost:11434/v1) or LM Studio. API key only if your endpoint needs one.

Prefer no AI? Leave this off — the canvas works fully without a model, analysis just won't be available.
