A Grammarly, But for AI Prompts
Looking for a Grammarly for prompts? Pretty Prompt is exactly that: a separate tool that polishes your prompts for AI, the way Grammarly polishes your writing.
(Not a Grammarly product.) It works just like Grammarly: where you prompt, inside ChatGPT, Claude, Gemini, in one click.
4.9 stars from 132 ratings. 40,000+ users.
The same idea, applied to your prompts
Grammarly improves your writing for humans. Pretty Prompt improves your prompts for AI. Same experience: one click, in place, as you type, but for prompts. The point is better outputs from ChatGPT, Claude and Gemini, without wasting time on trial and error.
Think of it as a one-click prompt enhancer or a prompt optimizer for any model. You type a rough request, Pretty Prompt rewrites it into a clear, structured prompt with the task, context, format and constraints models respond best to. You get better AI outputs without having to learn prompt engineering.
How it works
Step 1
Type or paste your prompt
Inside ChatGPT, Claude, Gemini, and all major AIs, or in the web app.
Step 2
Click once
Pretty Prompt rewrites it into a clear, structured prompt that gets a better answer.
Step 3
Send it
Edit whatever you like, then send it to the AI. Use Refine mode to tune it further.
Install the Chrome extension to use the prompt assistant inside the chat window of ChatGPT, Claude, Gemini, and other AIs.
Why use a prompt assistant at all
Most people do not write prompts the way AI models respond best to. They type a quick lazy prompt, and get a vague or off-target answer. Then go back and forth, rewriting and trying again.
A prompt assistant adds the structure for you. It enhances your intent with clear task, context, format and constraints. You get better AI outputs because the model knows exactly what to do.
That is what people mean when they search for a Grammarly for prompting or grammarly prompts: a tool that polishes what you send to AI to get better outputs. Pretty Prompt is built for that job, and does it in a click.
