Overview

Ptero is a free, browser-based AI chat platform that provides access to multiple powerful AI models in one interface. It is designed for users who want to experiment with or rely on modern LLMs without creating an account, paying for a subscription, or sacrificing everyday privacy. The service markets itself as completely free and open-source, with guest access via a random token stored in the browser and a display name saved locally. Regular conversations are kept in the browser rather than stored on Ptero's servers, while optional Projects and their custom files are stored in the cloud and linked to an account. Ptero routes messages to third-party AI providers to generate responses and notes that model availability may change over time, but access to the service itself will remain free.

Key Features

• Multiple AI models: Chat with several powerful models from a single interface, selecting the model that best fits the task.
• No signup required: Use Ptero as a guest with a locally saved display name and token; a WordPress account can also be used.
• Local-first privacy: Regular chat history stays in the browser; Ptero states it does not store non-Project conversation history in its database.
• Optional Projects with cloud storage: Organize chats into Projects, add custom files, and store project messages/replies on Ptero servers linked to your account.
• Always free: No premium plans, subscriptions, paywalls, or paid tiers; specific models may change, but access remains free.
