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.
