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.

10 complimentary responses, then annual access

Complimentary access includes 10 completed AI message responses once per account and does not reset daily, monthly, after reinstalling the App, or after changing devices. One response counts only when Serena delivers it; errors, canceled attempts and attempts without a completed response do not reduce the balance.

Tasks, contextual memory, voice notes, transcription, App Lock and optional encrypted backup are available without paid access. After the 10 complimentary responses are used, additional AI responses require active annual access. The annual plan renews automatically unless canceled in your Play account.

When annual access ends, Serena preserves your local history, tasks, memories and settings; additional AI replies require active annual access after the complimentary balance is used.

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 history stays on your device by default; encrypted remote backup is optional.

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

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.
