Stansa
AI chat and writing with model switching plus an OpenAI-compatible API in one service.
About Stansa
Stansa is a general-purpose AI chat and writing assistant built around a rotating lineup of standard and premium models. It lets people start chatting without an account, switch models within one conversation, search chat history on paid plans, and use the same model lineup through an OpenAI-compatible API. The service emphasizes direct responses with fewer content restrictions, while still prohibiting activities that violate U.S. or local law. Free access includes a small daily message allowance across model tiers. Plus removes message limits for standard models and provides very high premium-model limits subject to fair use; Pro raises those limits and adds faster responses, peak-hour priority, and priority support. Developers can buy non-expiring API credits and use existing OpenAI SDKs. The result supports individual chat, writing, model comparison, and application development. Premium usage limits and the relatively high Pro price remain important adoption considerations.
