Nexthena app

Built a local-first AI whiteboard app — free on Windows/Linux, $2 one-time on macOS [OC]

Hey all — I built Nexthena, a desktop whiteboard that runs entirely on your machine. No account required, no cloud sync, completely offline capable.

Why local-first?
Cloud whiteboard tools frustrate me. Login walls, sync delays, monthly bills, and your sketches living on someone else's server. Nexthena keeps everything local — your files, your machine, your control.

The AI part:
Type a prompt and Nexthena generates whiteboard elements or images for you — flowcharts, diagrams, concept visuals. You can edit them or insert them directly into your current canvas.

Full feature list:

  • Create from scratch, local files, or templates (flowcharts, sequence diagrams)
  • AI generation from text prompts
  • Excalidraw-compatible shape library
  • File search, trash & restore, export to image/file
  • Light/dark mode, keyboard shortcuts
  • Windows, macOS, Linux

Pricing:
Free on Windows and Linux. $2 one-time purchase on macOS (App Store). No subscriptions, no tiers, no upsells.

Would love feedback — especially from Mac users on whether $2 feels right or not.
