While you were away — Mamá proposed Saturday and asked if you’re bringing the cake.

Tía’s birthday

Mamá I was thinking Saturday for Tía’s birthday — everyone’s free. Can you ask Rafa about driving?

You Saturday works. I’ll bring the cake — the tres leches from the place she likes.

Saturday plan

Mamá Then it’s set: lunch at two. Not a word to her — it’s a surprise.

tap any paragraph — it plays from that moment

Every chat has a back. Flip it.

Other apps hide words inside audio. chapters keeps both — and lets you flip between them.

Written as you speak.

Every recado is transcribed on your phone at the moment you send it. Three keywords ride along on every bubble, so you know what’s inside without pressing play.

While you were away.

Come back after a day and a short note tells you where you left off — whichever of you was away. Read it, then answer like you never missed a thing.

Can’t talk? Type — it speaks as you.

Silent mode takes what you type and plays it in your own voice, cloned on your phone by Apple’s Personal Voice. Always labeled as typed — no one is fooled, only reached.

Nothing leaves your phone.

Transcripts, summaries, your voice — all made on-device. Synced only through Apple’s encrypted plumbing. We couldn’t read your conversations if we wanted to. There’s nothing to read them with.

Seven people maximum. That’s the map.

Questions, answered.

What is chapters?

A voice-messaging app for the few people you actually keep up with — seven at most. Every message you send is also readable, chaptered text, so a conversation becomes something you can go back and read.

Is it really private?

Yes — structurally. Transcripts, summaries and your voice are all made by your iPhone itself, and conversations sync only through Apple’s end-to-end encrypted iCloud. There is no chapters server, so there is nothing for us — or anyone — to read.

Why only seven people?

Because chapters isn’t for your contacts — it’s for your people. Seven is enough for the conversations you’d never want to lose, and few enough that each person gets their own colour.

When can I try it?

TestFlight first, and the waitlist gets the first invites. Join above and you’ll get exactly one email when it opens.

Android?

No — chapters is iOS only. It’s built on Apple’s on-device intelligence: the transcription, the summaries and the voice all happen inside the iPhone. An Android version isn’t planned yet.
