About this app

Serena is an AI companion for thinking things through, organizing what matters and finding a next step. Its context-aware memory can bring forward relevant details so conversations have continuity and repetition is reduced.



Perspective without taking over


Talk, breathe and organize your thoughts without judgment or pressure. Serena can help you consider different perspectives, but you decide and the choice stays yours.



What you can do



  • Type a message, send a voice note or listen to a spoken reply.

  • Continue conversations with context-aware memory and relevant details.

  • Create tasks with dates, times and gentle reminders.

  • Use English, Portuguese, Spanish, French, German or Italian.

  • Choose light or dark themes and readable text options.

  • Lock access with biometrics or device authentication.



Privacy and control, clearly explained


Your persistent conversations, memories, tasks and preferences stay in encrypted storage on your device by default. Serena has no ads. Review and delete your local data whenever you choose. AI replies and voice transcription are processed by service providers so those features can work.


Your local history remains available to review and manage even when your subscription isn't active. This does not include sending new messages or using subscription features.



Optional encrypted backup


If you enable secure backup, Serena encrypts the backup on your device before uploading the encrypted package and technical metadata for future restore. Access requires your recovery method.



A note on safety


Serena is a well-being companion, not a medical device or medical service. It does not diagnose, treat, cure or prevent any medical condition and is not a substitute for therapy or professional medical advice, diagnosis or treatment. Consult a qualified healthcare professional for medical advice. Serena is not an emergency service. If you are in immediate danger or need urgent help, contact local emergency services or an appropriate trusted resource.

Talk with context. Keep your history on your device by default.
