OpenGPT

OpenGPT is a web platform that lets you browse and use dozens of pre-built ChatGPT applications — or create your own in seconds. Instead of writing prompts from scratch in ChatGPT, you pick an app designed for a specific task, type in your input, and get a result. The platform covers everything from grammar correction and regex generation to blog writing, startup brainstorming, and even a Pokémon encyclopedia. Each app is essentially a tailored prompt wrapped in a simple interface.

The main page organizes apps into categories: Productivity Tools, Copywriting Assistant, Lifestyle & Entertainment, and Code Assistant. Click any app to see its description, then hit "Run" to open it. You enter your text (e.g., a sentence to correct or a topic for an essay) and the app sends it to ChatGPT with a hidden instruction. Sharing an app is as easy as copying its link — no login required for the person running it. If you want to make your own, the "Create Application" button lets you define the system prompt, name, and icon, and you get a shareable URL immediately.

OpenGPT is useful for anyone who uses ChatGPT for repetitive tasks. Content creators can quickly generate blog posts or improve their writing. Developers can convert natural language to regex or cron expressions. Business users can draft emails, resumes, or pitch decks. Because no coding or API keys are needed to use the apps, it lowers the barrier to getting specific results from ChatGPT without managing your own prompts.
