About this app

Looking for an AI to talk to that remembers what matters? Serena lets you chat with AI by text or voice, pick up familiar topics and keep your chat history encrypted on your device.

AN ONLINE CHAT WITH AI, AT YOUR PACE

Discuss the ending of a film, talk through a trip you're planning or explore an idea that just came to you. Start with a quick question, follow your curiosity and let the conversation grow. You choose where it goes.

A CONVERSATION YOU CAN COME BACK TO

Serena remembers interests, ideas and plans you share. Your taste for mystery films or the trip you're planning gives your next conversation context. Come back to share what you thought of a film or how your plans are taking shape, without introducing yourself all over again.

TALK TO AI BY TEXT OR VOICE

When speaking feels easier than typing, record a voice note. You can also write in the chat and listen to Serena's replies. Choose what suits the moment, whether you're telling a story in detail or sending a quick message.

TURN PLANS INTO TASKS AND REMINDERS

Ask in the chat: “Remind me to call my sister tomorrow at 6 PM.” Serena creates the task with a date, time and reminder. Use it for appointments, a reading break or something you've been meaning to get done. Get a reminder, see what's still on your list and mark tasks as complete. Plans changed? Reschedule the task right in the conversation.

YOUR CONVERSATIONS, UNDER YOUR CONTROL

Your history, memories, tasks and preferences are stored encrypted on your device by default. Lock the app with biometrics, a PIN or your device passcode, and review or delete your local data whenever you choose. Serena has no ads. AI replies and voice transcription are processed by external service providers.

SECURE BACKUP, WHEN YOU WANT IT

Remote backup is optional and encrypted on your device before upload, alongside technical metadata for restoration. Restoring your backup requires your recovery method.

MORE FOR YOUR DAY

• Talk in English, Portuguese, Spanish, French, German or Italian.


• Choose a light or dark theme and adjust text for easier reading.

ACCESS AND SUBSCRIPTION

Complimentary access includes 10 completed, delivered AI replies once per account. The balance does not reset daily, monthly, after reinstalling the app or after changing devices. Errors, cancellations and attempts without a completed reply do not use your balance.

After those replies, further AI responses require Serena Unlimited, an annual subscription purchased separately. It provides unlimited AI replies for one year of active access and renews automatically unless canceled in your Google Play account.

Tasks, contextual memory, voice notes, transcription, App Lock and optional encrypted backup do not require a subscription. Your local history, tasks, memories and settings are preserved when annual access ends.

Serena is not a medical device and does not diagnose, treat, cure or prevent medical conditions. Consult a healthcare professional for medical advice, diagnosis or treatment.
