Look up any term hands-free, build a personal vocabulary, and quiz yourself on what you heard — all without leaving the episode.
Unpack knows what the podcast is about. Every definition, highlight, and quiz is contextual — not generic.
Be first to unpack.
Free to use. No credit card needed.
A podcast drops a term you don't know. You fumble for your phone, pause, Google it, get the wrong definition because Google doesn't know the context, lose your place, and give up. Even when you follow along, the big ideas slip away by tomorrow.
Those moments cost you learning.
Unpack fixes both — definitions and comprehension — while you listen.
Unpack turns any podcast into a learning experience — completely hands-free.
Play any podcast. Unpack follows the transcript in real time so it always knows what's being discussed.
Hear something unfamiliar? Shake your head with AirPods or say "Hey Siri, define that." The right definition appears instantly.
After a few minutes of listening, a quiz pill appears. Tap it to test your understanding of what was just discussed. Audio never stops.
Every term and quiz builds your personal vocabulary. Spaced repetition brings it back days later so you actually remember.
Definitions, comprehension quizzes, vocabulary tracking, and spaced repetition — a complete learning system built around what you listen to.
Learns your gaps and flags unfamiliar words before you even ask.
Comprehension quizzes generated in real time from what you're hearing.
Spaced repetition turns one-time lookups into lasting knowledge.
See what you've learned, your strongest domains, and share your streak.
Overcast makes podcasts sound better. Unpack makes you smarter.
Every feature is designed around one idea: keep listening, keep learning, never break your flow.
Not a dictionary. Unpack reads the transcript around the moment you trigger, understands the topic, and returns the definition that fits. "UGC" in a marketing podcast means "User Generated Content" — not "Uganda."
Shake to trigger a lookup. Nod to select a term. No voice, no taps, no phone needed.
"Hey Siri, define that in Unpack." Works screen-off, phone in pocket. The definition plays through your AirPods.
Unpack learns what you don't know and highlights unfamiliar terms in the transcript — before you even think to ask.
Every term you look up enters a learning queue. Days later, Unpack quizzes you. Like Duolingo, but for the podcasts you already love.
Knowing words isn't the same as understanding ideas. As you listen, Unpack generates questions about the arguments and insights being discussed — not trivia. A pill appears when a question is ready. Tap it anytime. Audio never stops.
Track every word you learn. See your strongest domains, weekly streaks, and share your progress with friends. Knowledge is measurable.
Apple plays podcasts. Overcast makes them sound better. Unpack teaches you while you listen.
