Verdict
The clearest difference is in-app purchases: SpellBook AI at none against Jaspr's 1. SpellBook AI also leads on iOS requirement (13.0 vs 18.0). Jaspr's advantage is ads (none vs shown) and update cadence (every 5 days vs every 3 months). On price and device support there is nothing between them.
