Tonight's story picks up where last night's left off. Same world, same characters, still remembered. Read along word by word, in a voice your child knows. Tell Gramms what tonight's story should be about. A few minutes later your child is the hero of it, read aloud in a warm voice, with each word warming as it's spoken so they can follow along. And tomorrow night carries on from tonight. The next chapter opens the same book — same world, same characters, the thread still hanging where you left it. Chapter five still knows what happened in chapter one. A VOICE THEY KNOW Grandma is four time zones away. Dad is away for work. Gramms can read the stories in their real voice: they record a few seconds in the app, or you bring a recording you already have. It becomes a private reading voice that reads only your child's stories, and you can let it go whenever you like. HOW A NIGHT GOES - Type what tonight's story is about — a lost mitten, a brave dinosaur, the first day at a new school - A story comes back with your child's name inside it, read aloud, with artwork of its own - The words warm one at a time as they're read; tap any word to jump there - "Stop after a while" lets the story fade down gently instead of cutting off - Keep tonight's story on the phone and it plays with no signal at all - Leave an idea for what happens next, and the next chapter picks it up BUILT FOR THE END OF THE DAY Nothing interrupts a story once it's playing. No prompts, no pop-ups, nothing that would wake a child who is almost asleep. Stories are written for ages three to ten, and the telling changes with the hour: slow and quiet at bedtime, a proper ending in the afternoon. Stories can be told in English, Spanish, French, German, Italian or Portuguese. WHAT IT COSTS Three new stories a week are free, and the first loved one's voice is free to hear. Everything you have already made stays yours to play, always, at no cost. Gramms AI Premium lifts the weekly limit and lets you add more voices. - Monthly — $5.99 per month, after a one-week free trial - Yearly — $49.99 per year, after a one-week free trial Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the period ending. You can manage or cancel it in your Apple Account settings. Any unused part of a free trial is forfeited if you buy a subscription. HOW THE AI WORKS, PLAINLY OpenAI writes the stories and reads them aloud. We share your child's first name, their age, and your story idea — nothing else. If you bring a loved one's voice into Gramms, OpenAI listens to that recording first, to be sure a grown-up made it. Then our voice partner Cartesia makes the reading voice from it. OpenAI also listens to each finished story, so the words can light up in time with the reading. Nothing about a voice reaches either of them unless you choose to add one, and you can let a voice go at any time. You can remove any of it, and your whole account, from inside the app. Terms of Use: https://gramms.ai/terms Privacy Policy: https://gramms.ai/privacy

This update adds support for optional story-ready updates, available in a small pilot. When the option appears while your story is being made, you can ask for one quiet update. It is just for that story. You can cancel the request or pause story updates in Settings. Opening an update takes you to the requested story and leaves playback in your hands.
