Pretty Prompt
Grammarly for prompting
Visit website →About
Pretty Prompt is a writing aid for prompts, positioned as Grammarly for prompting. It sits in the browser and, as the user types into an AI chat box, suggests a clearer, more complete version, adding missing context, structure, and constraints.
It works across the common assistants, including ChatGPT, Claude, and Gemini, and can rewrite a rough request in place or expand a one-line ask into a detailed brief. Frequently used prompts can be saved and reused.
It is aimed at people who use AI daily but were never taught prompt craft, such as marketers, support staff, and analysts, who want better answers without studying prompt-engineering guides. A free tier covers basic rewrites.

Why we picked it
Pretty Prompt fills a gap none of the chatbots themselves solve — it sits in the browser and rewrites a rough request with missing context and structure before you hit send, working across ChatGPT, Claude, and Gemini alike.
