What Principia does best

* Smart conversations: chat naturally about any topic, follow up on previous answers, and get context-aware responses.
* Creative writing: draft emails, stories, poems, pitches, and marketing copy with ease.
* Coding help: write, debug, and explain code across languages and frameworks.
