Ptero
Ptero is a free AI chat platform built on two choices most competitors won't make: no account required, and conversation history stored locally in your browser rather than on their servers. It's open source, supports multiple models and multiple languages, and the local-first privacy stance means your chats aren't sitting in someone else's database. For quick questions, trying a model before committing to its native app, or contexts where creating yet another account is the friction, that zero-signup flow is genuinely convenient. The honest caveats: local storage means your history doesn't sync across devices and vanishes if you clear browser data; free multi-model access usually means rate limits or queues at peak times; and privacy here means they don't store your chats — the underlying model providers still process your prompts under their own policies. As a no-commitment front door to several models, it does the job well.
