Learn "Chip Away" in depth →Opposite directions, not variants of the same idea
"Chip in" means to contribute money, time, or effort; it does not mean to gradually reduce something. "Chip away at" means repeated small actions make something shrink. "Chip in" means one small contribution supports a shared effort, so the total may grow as people help.
Chip away at. "The team is chipping away at the backlog" — they are gradually reducing it.
Chip in. "Can everyone chip in $20 for the team lunch?" — they are contributing money, so the meaning points the other way.
These are separate expressions that share the word "chip." If you choose the wrong one, you may turn a progress report into a contribution request or change the meaning in another way.

Why this substitution is a real risk
The phrases share a core verb and a similar rhythm, which makes them easy to swap under pressure. The risk is not only awkward wording; the swap can reverse your meaning. "Chip in" may turn a progress update into a request for help or money. Yet you meant to report a steady reduction in a burden.
Confusing. "We're chipping in on the backlog this sprint" — this sounds like a group effort. It may suggest a one-time contribution to backlog work, not the gradual reduction that "chip away at" is designed to convey.
Use "chip away at" for steady progress against something. Use "chip in" when asking people to contribute money, time, or part of a shared effort.
A third, unrelated idiom worth knowing
A third phrase in this family is useful to recognize, although you do not need to use it yourself. "Have a chip on one's shoulder" means to carry resentment or a grudge, often after unfair treatment in the past. It has no link to "chip away at" or "chip in." It is a separate, unrelated idiom with the same root word.
Unrelated idiom. "He's had a chip on his shoulder since the reorg" — he carries resentment, which is not a sense of "chip away."
You may not need to say this phrase yourself, but recognizing it helps you keep all three meanings separate.
Use one practical rule for all three: check what is actually happening in the sentence. Is repeated effort making something shrink? Use "chip away at." Is someone contributing something? Use "chip in." Is someone carrying old resentment? That is the unrelated "chip on one's shoulder," which stays separate from the other two.
