Your Supernote tablet fills with handwritten journals, meeting notes, and sketches, and this server gives that handwriting a private home: Supernote is a self-hosted sync cloud for Ratta Supernote tablets that stores notebooks on your own hardware and can transcribe, summarize, and search them with AI. Point the tablet at your server under its Private Cloud sync setting and notebooks upload automatically, ready to browse in the web interface alongside your task lists and AI insights. Turn on the intelligence layer and each synced page is transcribed by a vision model, either Google Gemini or a local model served by Ollama or another OpenAI-compatible endpoint, so notes never leave your network. Analyzers then read your journals to surface tasks, themes, and Daily, Weekly, and Monthly summaries. Every word is indexed for semantic search, which understands concepts: searching for budget also finds pages about expenses or money, even when that exact word never appears. Tasks discovered in your handwriting export as calendar feeds that drop into Home Assistant, Apple Calendar, Google Calendar, and Outlook. An MCP server lets assistants such as Claude, Gemini, and ChatGPT answer questions against your notebooks, and notebooks convert to PDF, PNG, SVG, or plain text for use anywhere else. The hub idles at about 160 MB of memory, or roughly 135 MB in bare sync mode. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.
