About CustomGPT
Stop treating AI like a pen pal. Turn it into a productivity weapon.
Remember when AI was supposed to save you time? Now you spend 20 minutes "sweet-talking" a chatbot just to summarize an email. CustomGPT brings AI back to what it should be: a utility. No fluff. No small talk. No "How are you today?"
Select Text -> Right Click -> Done.
🚀 WHAT IS CUSTOMGPT? It is the ultimate "No-Chat" AI interface. It allows you to build a library of your favorite prompts and execute them on any website with a single click.
How it works:
You're on Gmail: Highlight an email, click your "Reply Professional" prompt. Done.
You're on GitHub: Highlight code, click your "Find Bugs" prompt. Done.
You're on a Spanish site: Highlight text, click "Translate to English." Done.
🔥 KILLER FEATURE: SMART CONTEXT RULES This is where CustomGPT outsmarts every other extension. You can set URL-Specific Rules.
On LinkedIn? Only your "Professional Networking" prompts appear.
On YouTube? Only your "Summarize Video" prompts appear.
On StackOverflow? Only your "Code Explanation" prompts appear. The extension adapts to where you are on the web automatically.
✨ KEY FEATURES:
✅ Your Personal AI Army Create specialized agents for every task: Grammar Fixer, Meeting Summarizer, Code Reviewer, Tweet Generator.
✅ Zero-Friction Workflow Stop switching tabs to ChatGPT. Stop copy-pasting. Just select text and click.
✅ Organized & Tagged Don't let your prompts get messy. Organize them with Categories (Work, Personal, Coding) and Tags so you can find the right tool in milliseconds.
✅ Automation Triggers Set up automations so specific prompts run automatically when you click specific input fields. (e.g., Click a reply box -> AI drafts a reply instantly).
✅ Powered by Gemini (BYO Key) We use Google's Gemini AI for lightning-fast, cost-effective responses. You use your own API key, meaning you have total control and privacy.
