How it works

Rewind in seconds.
Remember forever.

No setup, no accounts. Share an episode from any podcast app, hit capture, and Rewindio does the rest — entirely on your device.

01.
Share any episode
Use the Share Sheet from Spotify, Apple Podcasts, Overcast, or any podcast app. Rewindio handles the rest.
02.
Hit rewind
At any moment, tap capture. Rewindio saves the last 60 seconds and begins transcribing immediately on-device.
03.
Get your summary
Whisper AI transcribes the audio. An LLM turns it into a clean, readable summary — no cloud, fully private.
04.
Knowledge sync
Every rewind is saved locally and optionally synced to your knowledge workspace, organized automatically.

Rewindio Library — Premium

Your entire listening
history, searchable.

Favorite any episode for deep processing. Rewindio generates chapter-by-chapter summaries with timestamps, then indexes everything locally so you can search across every episode you've ever saved — semantically, not just by keyword.

Full episode transcription — Archive entire episodes, not just 60-second clips.
AI chapter summaries — Every episode is broken into chapters with timestamps you can jump to directly.
Semantic search — Ask questions across your entire library. "What did that economics episode say about inflation?" Just ask.
100% local, 100% private — All data stored on-device. No servers, no subscriptions, no data harvesting.

"You listen to hundreds of hours a year. Rewindio makes sure none of it goes to waste."

Every word stays.
