In plain English

Neural Brain is a local web dashboard for students who want to organize their study notes and review them with AI assistance, all without sending data to the cloud. It connects to a folder of notes written in Obsidian's Markdown format and uses a locally running AI model through Ollama to provide a chat interface and a quick note-refinement tool. The dashboard has several panels. A Map of Content registry shows an index of key subject directories such as operating systems, data structures, databases, and machine learning. Each subject gets its own page with notes listed alphabetically. A spaced repetition flashcard system automatically turns notes into study cards when it finds the special markers :: or ?? in the text, letting you flip between question and answer during a study session. A quick-capture buffer lets you type rough ideas and send them to the AI to be refined. A task panel syncs with a specific Markdown file in your notes folder to show your checklist items. The tech stack is a React front end built with Vite, an Express backend that reads your local files, and Ollama running on your machine as the AI engine. You can optionally point it at a Gemini API key if you want to use a cloud model instead. The README notes that scanning over 1,000 files completes in under 50ms thanks to a file-change caching system. The Windows setup uses a single batch script to start everything. On Mac or Linux you start Ollama and then the development server manually. The project is released under the MIT license.

Copy-paste prompts

Prompt 1

I have a folder of Obsidian Markdown notes organized by subject. Help me write a Node.js Express route that scans all .md files in a directory, extracts headings, and returns them as JSON.

Prompt 2

I want to build a spaced repetition flashcard parser in JavaScript that reads Markdown files and converts any line containing '::' into a question-answer pair. Show me the parsing logic.

Prompt 3

How do I connect a React frontend to a locally running Ollama model and stream the response token by token? Show me the fetch call and how to display it incrementally.

Prompt 4

Help me build a file-change caching system in Node.js that stores the last-modified timestamp of each file so I can skip re-indexing files that haven't changed.
