HOW SOLENA WORKS

Not a chatbot.
A four-layer AI system.

Most health apps give you a generic assistant. Solena builds a living model of your body — one that gets more accurate the more you use it.

Four layers that learn together

Each layer adds depth. Together, they understand things about your body that no single conversation or generic algorithm could catch.

1
Conversational AI

Your daily companion

Solena is available every day to talk about how you feel — whether you want to log a symptom, ask a question, or just say you're having a hard week. She understands English, Spanish, and Portuguese and responds in yours.

She reads the emotional tone of your message, not just the words
She never gives generic answers — every response is shaped by what she knows about you
She is a companion, not a diagnostic tool — she knows what she is and what she isn't
2
Episodic Memory

She remembers everything you've told her

Every conversation you have with Solena is stored as a memory — not just as text, but as a semantic fingerprint that she can search later. When you mention something in week 8, she connects it to what you said in week 2.

Memories are indexed by meaning, not just keywords — she finds relevance even when words differ
She draws on your actual history when answering, not a blank slate
Only you can access your memories — they are encrypted and isolated at the database level
3
Pattern Analysis

She finds patterns you couldn't see yourself

Every night, Solena analyses your last 30 days of logs and calculates which symptoms cluster together, how they correlate with sleep and stress, and whether they are getting better or worse over time.

Symptom frequency over 7 and 30 days — not just how often, but when
Sleep and stress correlations — does your next day feel worse after poor sleep? She checks
Trend tracking — is your experience improving, stable, or intensifying over time
4
Collective Intelligence

You benefit from what others are going through — anonymously

The Solena community is a source of collective knowledge. With strict anonymisation, Solena identifies patterns across groups of at least 20 similar women and surfaces insights no individual dataset could reveal.

No individual data is ever shared — groups must have at least 20 members before any insight is generated
GDPR Recital 26 compliant: truly anonymised aggregates are not personal data
What is happening for women like you right now — not general statistics from a medical textbook

Why this is different from other health apps

Most apps give you a generic AI assistant and a symptom tracker. They don't connect the two. Solena's four layers were designed to do exactly that — so the AI already knows your patterns before you start typing.

The result: instead of explaining yourself every time, Solena already understands the context. She knows your sleep is usually worse before a flare. She knows you've been managing anxiety better since last month. She doesn't ask you to repeat yourself.

Built around your privacy from day one

Health data is not like other data. We designed Solena's architecture with this as the constraint — not an afterthought.

🔒
Encrypted at rest
All your health data and conversations are stored encrypted in European servers (Supabase — Frankfurt, EU-West).
🔑
Row-level isolation
Database policies ensure you can only ever read your own data — not other users', not even accidentally.
🚫
Never sold
We will never sell, rent or share your personal data or health information with advertisers or third parties.
📊
GDPR compliant
Operated by 20-80 Editorial Unipessoal Lda, Lisbon. EU data protection law applies to every user, everywhere.
🗑️
Delete anytime
You can request complete deletion of your account and all associated data at any time, with no waiting period.
👁️
k≥20 anonymisation
Collective insights are only generated when a group has at least 20 members — individual patterns can never be isolated.
