Verdict
The clearest difference is price: TeachAI at Free against KnowledgeBase Builder's $8.99. TeachAI also leads on update cadence (every 4 days vs fortnightly). KnowledgeBase Builder's advantage is in-app purchases (none vs 9) and ratings volume (24 vs 3). On rating, ads, device support and iOS requirement there is nothing between them.
