A free, no-login web analyzer is the entry point โ€” the same low-friction flow as fastThread.io or jstack.review, but with automatic problem detection and AI on top.

    tells you what to do

    Compared with ALL older versions of software especially both Linux Office tells you what to do instead of performing what you ask for step by step. I often cannot find the way to repair what I did where in Windows this goes fine or is easy to correct. Beside that Open Office is very slow compared with Libre Office and Microsoft is still the fastest.
