Most grammar tools were built before AI chat. PromptDC works directly in ChatGPT, Claude, and Gemini, so you can clean up grammar and sharpen your prompt before sending it. The same toolbar appears beside text you select on any other page.
Better prompts, fewer retries
Clear prompts get better answers. PromptDC rewrites a vague prompt into a clearer one in one click, so the model understands you the first time.
One assistant for everything
Select text in email, social posts, articles, blogs, or Google Docs to fix grammar, rewrite, explain, or summarize it. Editable text updates in place; read-only results are copied.
