AstroBot
Your intelligent space-themed AI assistant — university graduation project.
AstroBot is a full-stack AI chat application built around an n8n workflow that routes messages through Mistral, with a layered set of features on top: image generation, OCR, retrieval-augmented generation (RAG), audio transcription, PDF report generation, image-to-image edits, and a separate admin dashboard.
