amassvspile up
Amass and pile up both describe a quantity growing large, but they pull apart on purpose and feel. Amass is to gather a great amount deliberately, usually something sought-after — a fortune, power, a collection. Pile up is informal and usually unwelcome, a disorderly heap mounting faster than we deal with it — debts, dishes and work pile up. Amass is the wanted hoard, gathered on purpose; pile up is the dreaded heap that just keeps coming.
A cloaked figure deliberately tips sack after sack of gold onto a glittering mound, prizing every coin — the heap is wanted, gathered on purpose, and its size is a triumph.
/əˈmæs//əˈmæs/·verbDirty dishes drop into a sink and stack up askew, leaning every way until the heap mounds over the rim — the heap is unwanted, disorderly, and grows faster than anyone clears it.
/ˌpaɪl ˈʌp//ˌpaɪl ˈʌp/·phrasal verbBoth end in a large amount, so 'amass debts' and 'debts pile up' can describe the same mess. The difference is intent and tone. Amass, from massa ('a lump'), is the deliberate, often ambitious gathering of something you want: wealth, an army, antiquities. Pile up is the colloquial verb for a heap that grows on its own and is usually a burden: a disorderly, dreaded excess. So a tycoon amasses a fortune with pride, while bills pile up with dread. You can even amass debts — but only when you mean someone ran them up on purpose; otherwise they simply pile up.
What each means
amass
To amass is to gather a great quantity on purpose — a fortune, an army, a vast collection, power. Where things accumulate almost on their own and you gather whatever is to hand, to amass is to build up a large amount through deliberate effort, with the emphasis on sheer size. It often carries a tint of ambition or greed: people amass wealth, regimes amass weapons. From the Latin massa, 'a lump', what you amass ends up a substantial, weighty whole.
pile up
To pile up is to accumulate into a heap — and, more often than not, an unwelcome one. It is the informal, faintly dreading cousin of accumulate: dishes, laundry, debts, unanswered emails and traffic all pile up, usually faster than we deal with them. The phrasal verb carries a sense of disorder and excess — of things mounting past the point of comfort — which is why the noun 'pile-up' can mean a motorway crash as readily as a backlog of work.

How to remember the difference
Both grow large — the split is wanted vs dreaded. Amass is the treasure hoard: someone gathers a great amount on purpose and is glad of the size (amass a fortune, amass power). Pile up is the sink of dishes: a disorderly heap that just keeps coming and you wish away (work piles up, dishes pile up). If a large amount is gathered deliberately and welcomed, it is amassed; if it heaps up unwanted and messy, it piles up. Tip: you amass treasure, but chores pile up.

They meet at unwelcome bulk — you can amass or pile up debts — but the framing differs. Amass implies someone gathered it on purpose (and often wanted it); pile up implies it grew on its own and is a burden. Wealth is amassed (sought); dishes pile up (dreaded). Swapping them flips the attitude.
