Gemini

Gemini is Google's play inside its own ecosystem, and that's where it shines: it summarizes Gmail threads, searches your Drive, works on Docs files and answers with real-time search context. As a model it's genuinely multimodal — it understands text, images and audio — and its context window is among the largest available, handy for analyzing very long documents. The paid plan also embeds AI features directly inside Gmail, Docs and Sheets, which for anyone already living in the Google universe is a real time saver. Outside the Google ecosystem, though, other assistants are a step ahead in writing nuance and coding.
