FAQ
Switching from SimpleMind.
Does Pellven open my .smmx files directly?
Yes. Pellven reads SimpleMind's .smmx format — the ZIP-packaged XML that holds your hierarchy, notes, cross-links, hyperlinks and images — and rebuilds it as an editable map. No conversion step, and your original file is never modified.
Is there a one-time purchase, like SimpleMind?
Yes — that's the point. The Recover licence (£79 one-time) and Everything (£149 one-time) are lifetime purchases. No subscription required.
Does Pellven work offline?
Yes. It's a desktop app that works fully offline. Your maps stay on your device, never uploaded by default.
Which platforms does Pellven support?
macOS and Windows desktop.
