I'm missing some information on how this works (a LLM? which? Do I need to bring an API key? Does this work offline?) and what I can expect in terms of performance/battery hit.

It is Gemma 3n, I can't give feedback yet on the battery hit, But I would not expect anything bad as these models have been developed for much smaller devices (Phones)

Considering that it mentions offline capability I'd say local tiny LLM.
