Verdict
The clearest difference is price: Instantly AI at Free against WriteTone's $0.99. Instantly AI also leads on ratings volume (32 vs 1) and update cadence (every 6 weeks vs every 4 months). WriteTone's advantage is rating (5.0 vs 3.1). On ads, in-app purchases and device support there is nothing between them.
