Key takeaways
• The AI apps market now spans six clear categories — chat, image, video, writing, code, and productivity — each with a distinct leader.
• ChatGPT remains the default AI app by reach, but Claude, Gemini, and Perplexity each win specific jobs-to-be-done.
• Image and video are the fastest-moving categories; Flux and Sora reset quality expectations in 2024–25.
• Free tiers are the norm — budget for one or two paid subs, not five, unless stacking is justified.
• If you hit two or more categories, a multi-model hub like ZeroTwo is cheaper than maintaining separate subscriptions.
