Ptero

What it is

Ptero is a web chat platform that gives free access to multiple third-party AI models. It describes itself as nonprofit and states in its terms that it will not introduce paid plans or paywalls. You can start as a guest by picking a display name, or sign in for an account. Regular conversations are stored locally in your browser rather than on Ptero's servers, so clearing browser data removes them. Cloud storage is used only for projects and their custom files. The interface is available in about 20 languages, and the team shares news and gathers feedback through a Discord community. A developer section is also offered.

Editor's notes

More context from AI BirdView

Ptero takes an unusual and welcome stance for an AI chat service: it says it is nonprofit and promises in its terms that it will always stay free, with no premium tiers. Pair that with local-first storage of your conversations and it becomes an appealing option for people who want to try different models without handing over an account or chat history.

Several AI models available from one chat interface
Guest access with just a display name, no sign-up required
Regular chats are kept in your browser, not on Ptero's servers
Projects with custom files for longer-running work, stored in the cloud
Interface translations in about 20 languages and an active Discord for updates

It is best for students, hobbyists and curious users who want free access to multiple models, like comparing answers, and value privacy. Because chat history lives in your browser, export or copy anything important before clearing site data or switching devices, and use projects for material you need to keep across sessions.
