Heygpt

Heygpt is a browser-based interface designed to help users get more control and reliability from ChatGPT by connecting with their own OpenAI API key. It removes the need for account logins, providing direct access to ChatGPT even during peak usage periods when the official interface may be slow or unavailable. The primary purpose of Heygpt is to offer a faster, more flexible, and feature-rich environment for everyday and professional AI-assisted work.

The tool supports advanced document handling, including chatting with multiple PDFs at once, making it suitable for research, legal review, academic work, and technical documentation analysis. It integrates text-to-speech and speech recognition, enabling hands-free interaction and accessibility-focused workflows. Users can search across past conversations, tag chats for organization, and quickly retrieve relevant threads, improving long-term knowledge management. Because it runs on the user’s own API key, it also offers more predictable performance and clearer cost control compared to opaque subscription models.
