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 endpoint to analyze cards or the whole board (AI Advisor). Keys stay in this browser — SlideNebula has no server. Tip: stop the Base URL at /v1 (do not include /chat/completions).

Example: https://openrouter.ai/api/v1 (stop at /v1 — do not add /chat/completions). Local Ollama: http://localhost:11434/v1.

OpenRouter: create a key at openrouter.ai/keys. Leave blank for local servers that don’t need one.

Free test: openrouter/free. Claude via OpenRouter: anthropic/claude-sonnet-4. Local: e.g. llama3.2-vision.

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