Cushion launches local-first markdown workspace with AI

Hot take: this feels like a credible “writer’s IDE” pitch rather than a generic AI notes clone, and the open-source angle makes it more interesting than the average PH launch.

• –The core wedge is strong: local-first markdown plus native AI chat is a clean answer to the “notes app vs AI assistant” split.
• –The repo README shows real product thinking, not just a demo: dictation, PDF support, Excalidraw, and roadmap items like CSV/XLSX and split-page view.
• –The product still looks early-stage, so the main risk is polish and depth of workflow features versus established tools like Obsidian or Tana.
• –If the AI sidebar and local dictation are fast and reliable, this could be genuinely sticky for heavy note-takers.
