Gemini
Google's chat assistant, built to hold very long documents at once
Runs in a browser, on phones and inside Google's own products. Context length is the selling point: paste in a long report or a whole code base and ask it to find the one line that matters. There is a free tier and paid plans for the larger models. It invents facts, the same as every assistant of this kind.

Search questions go to Gemini. He calls the product frustrating, timing out on the app and losing the plot, but rates the data underneath: the Google crawl plus YouTube. It is not the best model in his view, just the one sitting on the best index.
