Fastest-growing use cases
Vibe coding and full-stack AI development
The biggest shift in AI use in 2026 is non-technical users prompting AI to build working applications. Lovable, Cursor, and Claude Code have each reported millions of monthly active users building real products through natural language prompting.
Voice and audio content creation
ElevenLabs (valued at $11B), Suno, and Udio have brought AI audio generation into mainstream creative workflows. Script writing for AI narration and podcast production are the top two voice AI use cases.
Multi-step AI agent workflows
As AI agents matured, the demand for system prompts, memory instructions, and multi-step workflow prompts exploded. This is the most technically advanced growth category and largely limited to developer and power-user audiences.
AI tutoring and homework explanation
Students are using AI for subject-specific tutoring at scale. Math, science, essay writing, and language learning are the top four student use cases. This growth is happening on ChatGPT, Claude, and Gemini roughly equally.
Short-form video scripts for TikTok and Reels
As brands shifted to video-first social strategies, AI script writing for short-form video became one of the most widely adopted content creation use cases. Hook writing and storytelling-format scripts are the most requested prompt types.
