Use Prompt Rewriter to: - Save time when writing AI prompts - Turn quick thoughts into polished instructions - Get clearer, more useful AI answers - Improve prompts for work, school, research, planning, writing, and everyday questions - Choose short, balanced, or deeper responses - Ask the AI to include sources when needed - Format answers as checklists, tables, roadmaps, decision memos, or one-page briefs Prompt Rewriter is useful for anyone who uses AI tools and wants better results with less effort. It can help with emails, brainstorming, learning, content writing, business planning, decision-making, summaries, research questions, and professional communication.

The clearest difference is ads: Prompt Rewriter at none against Quill's shown. Prompt Rewriter also leads on iOS requirement (15.0 vs 26.2). On price, in-app purchases and device support there is nothing between them.
