Is Ptero really free to use?

Yes. Ptero is completely free and is committed to remaining free permanently — there are no premium plans, subscriptions, or paywalls. Every model available on the platform can be used at no cost.

Do I need to create an account to use Ptero?

No signup is required. You can start chatting as a guest identified by a randomly generated token saved to your browser's local storage. You may optionally sign in if you want access to the cloud-synced Projects feature.

Where are my conversations stored?

Regular chats are stored only in your browser's local storage and are not retained on Ptero's servers. Only chats that you explicitly file inside a Project — along with that project's title and any custom files — are stored on Ptero's servers and synced to your signed-in account.

Is Ptero open source?

Yes. Ptero is fully open source. The complete source code is available on GitHub at https://github.com/Ptero-ai/Ptero so anyone can inspect exactly how the AI chat works.

Can I import an existing GitHub project into Ptero?

Yes. Ptero lets you import a public GitHub repository by pasting either a full GitHub URL or an 'owner/repo' reference, then you can ask the AI questions grounded in that code.

Which AI providers does Ptero use?

Ptero routes your messages to independent, third-party AI providers associated with each model. Your messages are forwarded to the provider you choose and responses are returned to you; Ptero does not store ordinary chat content on its own servers.
