I built NexusForge: The Multimodal AI Agent Hub for Notion

This is a submission for the Notion MCP Challenge NexusForge is a multimodal workflow app for Notion. It turns screenshots, whiteboard photos, rough sketches, and messy prompts into structured Notion-ready deliverables. The strongest workflow in the app is diagram to technical brief: upload a system design image, ask for a concise engineering summary, and NexusForge produces a clean markdown artifact that can be previewed immediately and published into Notion as a child page. I built it to solve a very practical problem: visual thinking happens early, but documentation usually happens later and manually. NexusForge closes that gap. It combines: ✅ Gemini 3 Flash Preview for multimodal understanding ✅ Notion API for creating real pages from generated markdown ✅ Notion MCP configuration in the workspace, so the repo is ready for direct Notion MCP OAuth in VS Code Reliability Hardening To make the app safer for broader public use, I added: a Notion page picker backed by live workspace sear
