I liked Obsidian. I liked Cursor. But I kept switching between the two and never fully settled in either. Obsidian's markdown editing felt great, but it had no AI chat that felt native to me, and honestly I spent way too much time finding the best theme and best plugins. Cursor, on the other hand, had the AI sidebar I wanted, but it's a code editor and writing long-form text in it was exhausting. I wanted one app that did both. And I didn't want to pay for another subscription just to get AI in my notes. So I started building Cushion. Not as some grand plan, just to solve my own problem. When I needed dictation, I added local speech-to-text. When I wanted to chat with AI while writing, I integrated OpenCode (with MCP, skills, agents, the whole thing). Diagrams? Excalidraw. PDFs? Built a viewer. NotebookLM? Plugged it in. It kept growing from there. It was only for me at first. But at some point I figured, why not open source it. So here it is. Use it, fork it, break it apart, whatever you want. Would love feedback to keep growing Cushion !!
