I was copy-pasting the same 5 paragraphs into ChatGPT every single time. My product description. My writing style. Reference examples. So I built ContextOne: save it once, type @@@, inject everywhere. Now my prompts go from "write me a post" to "write me a post that sounds like me, knows my product, and follows my best examples." The shortcut to prompts that actually work →

3 years ago, I spent 15 minutes crafting the perfect ChatGPT prompt. Product description (copied from docs). Writing style guide (pasted from Notion). Example posts (pulled from saved tweets). Every. Single. Time. I thought: what if I saved these once and injected them anywhere? That's ContextOne. Type @@@ in ChatGPT, Claude, or any text field → AI finds relevant context from your library → insert with one click. The difference? ❌ "Write me a LinkedIn post" ✅ "Write me a LinkedIn post with my voice, my product details, and my best-performing examples" Great prompts create great output. ContextOne is the shortcut. → Free download in comments
