I uploaded a character-setting document and it was blocked at once with a safety warning. Ordinary files in the same format are fine. Stuck at this step, the whole workflow stalls.

I tested it on a round of math and coding problems. Looks convincing, but look closely and plenty is wrong. Confident nonsense wastes the most time; I have to check it line by line.

What annoyed me most was re-explaining the background in every new chat. Since memory was added that's gone; I just pick up where we left off.

Select-to-translate and screenshot recognition in the browser are really useful. But you can't even rename a chat there; you must jump to a separate page, and switching back and forth is awkward.
