I want to build a fully closed, self-hosted AI system for my own day-to-day use. The solution should run locally (or within my private network) without routing data through external clouds or third-party APIs once deployed. At its core, I need several cooperating “agents” that I can customise with different personas and skill-sets, all drawing on the same knowledge base. The assistant must be able to: • Co-create written, visual or slide content with me in real time • Act as a personal coach, helping me set goals and break them into actionable plans • Review my notes, files and datasets, highlighting trends or insights and suggesting next steps • Switch between (or simultaneously run) multiple agents whose tone, expertise and access rules I can configure on the fly A clean, minimal interface—CLI, desktop app or web dashboard—is fine as long as it is private, responsive and easy to extend. Deliverables 1. Source code with clear modular structure 2. Setup script or Dockerfile for one-click local installation 3. Brief user guide showing how to add or tweak agent personas 4. Short demo (video or live session) confirming the features above work offline Acceptance criteria: all features run locally, no outbound calls after installation, and each agent can be edited through a simple config file or UI pane. If this sounds like your kind of build, let’s discuss architecture choices and model selection so we can get started.
