About Ptero
Ptero is an AI chat platform for developers that provides access to multiple AI models through a browser-based workspace. Users can start conversations as guests, choose available models, debug code, analyze files, and use prompts for coding and research tasks.
Regular conversations are stored locally in the browser, while Projects can sync chats and custom files to Ptero’s cloud. Project files can be edited through a browser code editor, previewed, copied, downloaded, and saved to cloud storage.
Ptero also provides a developer API with OpenAI-compatible chat completion and Responses endpoints. Applications can authenticate with API keys, select configured models, send standard chat messages, and receive regular or streamed responses.
The platform is free and states that it has no premium plans, subscriptions, paywalls, or paid tiers. It is open source, supports guest access, and routes submitted messages to the selected third-party AI provider to generate responses.
