Pretty Prompt

Pretty Prompt is a Chrome extension and web app that acts like Grammarly for AI prompts — it rewrites vague, sloppy instructions into clear, structured, context-rich prompts in one click, right inside the ChatGPT, Claude and Gemini textboxes. It launched on AppSumo in May 2025 and has grown to 40,000+ users. The free tier improves 5 prompts a week; the Pro tier was on a $39 lifetime deal (78% off $180) that is currently sold out.

What is Pretty Prompt?

Pretty Prompt is a Chrome extension and web app built by London-based co-founders Ilai Szpiezak and Charlie Day to scratch their own itch: crafting precise AI prompts. It injects an "improve" button into the textboxes of ChatGPT, Claude and Gemini, rewriting vague or context-light instructions into structured, role-based prompts — with a "Refine" mode that asks follow-up questions to add context, plus a library and searchable history for storing and reusing your best prompts. Since its May 2025 launch it has grown to 40,000+ users and shipped a broad feature set: Image to Prompt (reverse-engineering visuals into prompts), a Prompt Playground for comparing prompts across models with your own API keys, a public 200+ template library, an MCP server for Claude and Pretty Chat for chatting with any webpage. It targets creators, marketers, consultants, founders and developers who live in AI chat tools daily. The free tier improves 5 prompts a week; the Pro lifetime deal on AppSumo started at $39 for 200 prompts/month and is currently sold out.

Who is it for?

• Content creators and marketers generating copy, thumbnails or social posts with AI daily
• Consultants, founders and agency owners who want consistent, high-quality prompts without prompt-engineering effort
• Developers doing "vibe coding" or using AI assistants in their IDE and browser
• Non-native English speakers who want well-structured prompts without writing perfect English

Who is it NOT for?

• Casual users who prompt AI a few times a week — the free tier already covers them
• Anyone already comfortable writing detailed prompts who won't notice better rewording
• Enterprises needing SSO, compliance or formal vendor review — tiny vendor with no enterprise-grade proof
• Anyone looking for a tool that generates the AI output itself, not just rewrites the input
