“...a run of product-strategy podcasts this week, and one video essay on stoicism that’s stuck with me since...”

You get through hours of it every week. By Friday, most of it’s gone.

An idea from a lecture, a stat from a podcast, the video that changed how you saw something — heard once, then gone. Earzbook keeps it, and turns the whole week into something you can actually look back on.

Record your day. Get your week back.

No setup rituals, nothing to remember to do. Three steps from an ordinary day to a week worth keeping.

  1. 01

    Capture

    Turn it on once, in the Chrome extension or the Android app, and it keeps listening in the background — the tab you’re on, or your device’s audio.

  2. 02

    Your week, made

    Earzbook sorts what you listened to into themes and turns it into one recap card — the shape of your week, not a wall of transcript.

  3. 03

    Share it, or don’t

    Post your week for friends to see, react to, and comment on — or keep it fully private.

Privacy

What gets shared is always your call.

Not a promise on a page — guarantees built into how the product works.

Envelope-encrypted transcripts

Every user’s data is sealed with AES-256-GCM, and the key is wrapped in Google Cloud KMS. A database or vector-store breach reads nothing.

Your call, every week

A week stays fully private until you choose to post it — public, friends only, or not at all. Nothing goes out without you deciding first.

True delete

Deleting your account (after a 14-day grace period) destroys your per-user key — content it protected can never be decrypted again, not even by us.

We never sell your data to advertisers or third parties.

The week post

Your week, as one card worth looking at.

Not a transcript to scroll through — a single recap that says what the week was actually about, built the moment you’re done recording it.

  1. 1

    Made for you

    No journaling, no summarizing your own week. Earzbook reads what you actually listened to and builds the card for you.

  2. 2

    Yours to show

    Every week is private until you choose otherwise — post it publicly, share it with friends only, or never publish it at all.

  3. 3

    A record that adds up

    One card a week becomes a running history of what you were into, listening to, and thinking about — months and years back.

Whatever gets recorded becomes something you can look back on, share, or ask about.

A recap, every week

Your week, automatically turned into one card: what you listened to, and how much of it there was.

Friends, reactions, comments

Share a week publicly, with friends only, or not at all. Upvote, comment, and see what your friends are into.

A living map of everything you’ve listened to, and how it’s grown — visible on every profile, including yours.

Ask your own past

Encrypted by design

Per-user envelope encryption means a database breach reads nothing of yours.

Chrome + Android

Tab audio in your browser, device audio on your phone — one account, one memory.

99 languages, auto-detected

No language picker required. It figures out what it’s hearing, and switches mid-stream.

Start your first week.

Listen to a few things this week, and Earzbook turns them into a week worth keeping.

Get the Android appAdd to Chrome
What exactly does Earzbook record?
In Chrome, it captures the audio of the specific browser tab you are recording — not your microphone, not your screen, and not your system audio. On Android, it records the device audio you choose to capture. Recording only ever starts from a deliberate action: clicking the toolbar icon, pressing play, or using the keyboard shortcut.
Is my audio stored anywhere?
No. Raw audio is processed transiently to produce the transcript and is never saved — there is no audio field and no upload path. Only the transcript text is stored, organised by your device’s local calendar day.
Is Earzbook free?
Earzbook is a paid service with a free allowance. Recording time is sold as prepaid credits measured in seconds — one credit is 3,600 seconds (one hour). New accounts get a one-time, non-recurring 30-minute allowance. Checkout is web-only and handled by Razorpay.
Is there an iOS app?
Not today. Earzbook ships as a Chrome extension (Google Chrome specifically — not Firefox, Safari or Edge) and an Android app.
Do I need an account?
Yes — a free Earzbook account, created with Google sign-in or an emailed one-time code. Your recordings and week posts are tied to that account, so they stay yours and you control who gets to see them.
Can I keep my weeks private?
Yes, and that’s the default. Each week, you choose whether to publish it — publicly, to friends only, or not at all. Nothing is shared automatically.
What do my friends see if I share a week?
The recap card you published: its themes and the excerpt you’re sharing, plus your knowledge radar and timeline. They can react, comment, and see how your week compares to theirs. A private week is never visible to anyone.
Is my data end-to-end encrypted?
No, and we would rather say so plainly: this is strong encryption at rest, not end-to-end. Each user’s data is sealed with AES-256-GCM under a key wrapped in Google Cloud KMS, so a database or vector-store breach reads nothing. But our servers do decrypt content in memory to show it to you and to generate your insights.
Does my transcript get sent to an AI company?
Yes, in one specific way: transcript text is sent to xAI (the Grok API) to generate your knowledge insights — themes, interest labels and summaries. xAI is a named subprocessor in our Privacy Policy. Your recordings are never sold, and never used to train a model.
What happens when I delete something?
Permanently deleting a recording removes its transcript, embedding vectors, analytics and paragraph index. Deleting your whole account additionally destroys your per-user encryption key after a 14-day grace period, after which content encrypted under it can never be decrypted again — including by us.
Which languages does it support?
About 99, detected automatically. There is no language picker — it identifies what it is hearing and can switch mid-stream.
