Decide now
We often use will when we make a decision as we speak: The phone is ringing. I’ll answer it. I’ll means I will. Put the base verb after will; do not add to or -s.
I’ll answer the phone.
We’ll take the bus.
The full form and the contraction
Won’t is the contraction of will not. Keep the base form be after either version.

Offer help
Use I’ll + an action to offer help: I’ll carry that bag. Use a helpful tone. The form stays the same with every person: he will help, not he wills help.
I’ll carry your bag.
I’ll show you the room.
Make the offer fit the situation
I’ll means I will. The speaker volunteers to carry one particular bag, the blue one.
The other bag’s neutral colour is only an illustration aid; the recording identifies the blue bag.Make a promise
Use will for a promise and won’t for a negative promise: I’ll call tonight. I won’t forget. Won’t means will not. The following verb stays in its base form.
I’ll call you tonight.
I won’t forget.
The promise includes a time
Will is followed by the base verb call.
The speaker promises that forgetting will not happen.
