What is Ptero?
Ptero is a non-profit chat site where you pick a name and start talking to a choice of AI models with no account and no fees. Conversations are stored only in your browser, which suits people who want quick, private access to several models.
Its terms say the service is free and will never add paid plans, though the selection of models may change. Regular chats live locally on your device, while projects and their custom files use cloud storage, and the interface is available in more than 20 languages.
Developers can call a public API with a Responses-style endpoint and a models list, and choose work modes such as a fast mode for short answers. The code is published on GitHub and the community gathers on Discord.
