Frequently Asked Questions
Final Verdict
FlatAI Rating: 3.4/5
FlatAI delivers on its privacy promise—your creative work genuinely stays private with local-only storage. For users who prioritize privacy above all else, this is a meaningful differentiator.
However, the tradeoffs are significant. No cloud sync means losing browser data erases everything. The unclear pricing and limited documentation make it hard to evaluate before committing. And the feature set is basic compared to more mature platforms.
Our recommendation: FlatAI is worth trying if privacy is your primary concern and you're comfortable with local-only storage. But for most users who want reliable access to their creations, clear pricing, and a comprehensive feature set, Kosoku AI provides a better overall experience with secure cloud storage.
