Meaning starts with use, not with a Standard Arabic replacement.
شو may correspond to ماذا or ما in some contexts, but that does not make it an unfinished version of either. Bayan keeps the form you wrote and explains it from within its use.

A phrase can change with the speaker, audience and setting. Bayan should make that context visible instead of flattening it into generic Arabic.
The English page explains the linguistic context rather than pretending to reproduce it.

«شو بدك؟» is not a mistake. It is Palestinian Arabic. Bayan starts from the language you chose. If you want a more formal version for a particular situation, you ask for that change.
شو بدك؟ can sound completely natural with someone close. In another situation you may want something softer. If you want Standard Arabic, Bayan moves there because you asked, not because the dialect was wrong.
شو بدك؟ can stay exactly as written with someone close. Nothing needs correcting.
Enter the word or expression as you use it. Choose a region only when you mean one. Otherwise leave the search unfiltered.
Start with a word you actually use. Bayan's Palestinian knowledge is still bounded, and an unknown word does not automatically become an error.
You do not need a wall of feature cards. The word itself is the starting point. From there, open its meaning, use, grammar, regional evidence or the situation in which it is being said.
شو may correspond to ماذا or ما in some contexts, but that does not make it an unfinished version of either. Bayan keeps the form you wrote and explains it from within its use.
When regional or usage evidence is weak, uncertainty should remain visible instead of turning into a fabricated answer.
Sometimes you write this way because it is your language. Bayan's job is to understand that before suggesting a change, and to make any move towards another form an explicit decision you make.
Bayan's Palestinian knowledge is not a finished dictionary. It is a bounded local pack that can grow while its limits remain visible when the evidence is not strong enough.
You can narrow the search to the places shown in the tool when you mean one of them. The filter helps retrieval. It does not draw hard borders around the dialect.
When Bayan has reliable knowledge about a word or use, the confidence or source should remain visible rather than disappear behind the answer.
If the current pack does not contain enough evidence to judge a use, Bayan should say so. An unknown word does not automatically become an error.
If you need a root, dictionary entry or wider source, you can move into Arabic Memory without treating the Palestinian form as something that first needs replacing.
