Open GPT is a subscription product distributed as open-gpt.app, with checkout and billing handled through Lemon Squeezy. It is aimed at people who want a ChatGPT-style assistant and a set of AI-powered utilities accessible from one subscription, rather than juggling multiple single-purpose tools.
The offering centers on practical everyday work: chatting with an AI assistant, drafting and refining written content for marketing or documentation, getting help writing and debugging code, and assembling small AI-powered applications and productivity helpers. This makes it useful for creators, marketers, and developers who want one place to reach an LLM-backed assistant.
Plans run from $4.00 to $16.00, which typically map to different usage levels and feature sets, and the subscription is managed and processed by Lemon Squeezy. If you are considering it, review the specific tier features at checkout to match your usage needs.
