Ptero

Ptero.pro provides an AI chat platform that runs in the browser and stores conversations locally by default, while offering optional project-based data stored on servers. The service is positioned for developers and users who want a no-cost chat experience with model variety.

Ptero.pro operates with a model catalog that routes user messages to third-party AI providers to generate responses. The platform outlines how data flows from user messages to providers and back, and notes that conversations may be stored in projects on servers or locally in the browser, depending on context.

Ptero.pro highlights local-first privacy for chats outside projects, with browsers storing chats locally and project data stored on servers linked to the sign-in account. The policy mentions that users can clear local storage to remove guest identity and chats outside projects but that project data remains on servers.

Ptero.pro is a free, non-profit chat platform with no paid plans, and emphasizes that all models are provided at no cost. It outlines acceptable use and responsibility for evaluating outputs, and describes how models and content are handled across providers.
