Launched in January 2024, it functions as a <strong>App store for artificial intelligence<\/strong>. In 2026, with the arrival of GPT-5 and agentic workflows, the GPT Store became an indispensable tool for <strong>Automate tasks, analyze data, and boost productivity<\/strong>.<\/p>\n<\/div><\/div><\/p><p>ChatGPT is part of your daily life, but you probably still use the basic model for everything. You type your prompts by hand, rephrase them three times to get the right result, and start over with each new conversation.

Instead of starting from scratch each time, you access <strong>pre-configured and specialized assistants<\/strong> for specific tasks: data analysis, image generation, writing, programming, education. And if no GPT matches your needs, you can <strong>create yours in minutes<\/strong>, without writing a single line of code.<\/p><p>This guide covers everything: from accessing the GPT Store to creating your own GPT, including the best GPTs to use in 2026 and strategies for getting the most out of this platform.<\/p><h2 id=\"definition-gpt-store\">What is OpenAI's GPT Store?<\/h2><p>The GPT Store is a <strong>marketplace<\/strong> (marketplace) integrated directly into the ChatGPT interface.
