The first AI foundation model for mental health care
General-purpose AI models aren’t designed for the complexity of psychiatric care.
Our foundation model, trained on voice, language, clinical context, and behavioral signals, captures the clinical heterogeneity inherent in psychiatry.
Tried and tested
Our foundation model can assess depression, anxiety, insomnia, fatigue, cognitive decline, suicidal ideation, and more. Eight clinical trials are ongoing with leading institutions.
Built by world-class experts
Our team combines deep expertise in AI, neurosciences & healthcare — with research affiliations at Oxford, Harvard, and leading European psychiatric hospitals. We've published peer-reviewed work on speech-based mental health assessment, suicide risk detection, and multilingual clinical NLP.
Security & Compliance by Design
We meet the strictest healthcare data security and privacy requirements. No data is shared with third parties or used to train AI models without explicit consent.
Peer-reviewed. Clinically validated.

FAQs
How is Callyope different from general-purpose AI tools like ChatGPT?
General AI models aren't built for the complexity of mental health. Callyope is powered by a foundation model trained specifically on psychiatric data, which makes it significantly more accurate and reliable forpsychiatric workflows. For example, our patient case summaries are +50% more accurate than thosegenerated by general-purpose LLMs.
How does Callyope integrate with my existing EHR/workflow?
Callyope is designed to fit seamlessly into your existing clinical workflow. We integrate directly with major EHR systems to eliminate double data entry—clinical information flows automatically, and our outputs (summaries, reports, notes) can be pushed back into your EHR in the right format. For systems without direct integration, we offer secure data exchange methods that still minimize manual work.
Is my patient data secure?
Absolutely. Patient data security and privacy are fundamental to how we've built Callyope. We are ISO 27001 certified, use HDS-certified hosting for all health data, and are fully GDPR compliant. Your patient data is encrypted in transit and at rest, never used to train our models without explicit consent, and never shared with third parties. We meet the strictest healthcare data protection standards in Europe
Does this aim to replace clinician judgment and diagnostic?
No. Callyope is designed to support clinicians, not replace them. Our AI handles time-consuming administrative tasks and provides objective data to inform your clinical decisions — but you remain in fullcontrol of diagnosis, treatment planning, and patient care.
How accurate is the AI?
Our patient case summaries are 50% more accurate than summaries from general-purpose LLMs. Our voice-based symptom assessment evaluates 10+ symptoms with over 90% accuracy from just 30 seconds of speech. All models are validated against clinical standards and real-world outcomes through ongoing trials with leading institutions.
What types of medical documents can Callyope analyze?
Callyope can analyse a wide range of psychiatric medical documents: consultation notes, hospitalisation reports, prescriptions, referral letters, and more. Our system handles unstructured clinical text in multiple formats (PDFs, Word documents, EHR exports) and extracts relevant clinical information automatically.
What's the difference between Callyope's AI platform and foundation model?
Our foundation model is the AI engine— trained specifically on psychiatric data to understand mentalhealth's unique complexity. Callyope is the suite of clinical tools built on top of that engine, designed to fit into your daily workflow. One specialised AI engine, multiple purpose-built tools.
How can Callyope assess symptoms based on behavioral data such as speech or sleep?
Our Foundation Model is trained on multiple behavioral signals—including voice patterns, speech content, sleep data, and activity levels—alongside clinical context. These signals contain clinically meaningful patterns that correlate with mental health symptoms. For example, changes in speech tempo, prosody, and linguistic patterns can indicate depressive or manic states. By analyzing these signals longitudinally and contextualizing them with documented treatments and clinical history, our model can detect subtle changes that may signal symptom progression or relapse risk—often before they're apparent in clinical observation alone.
What's the difference between foundation models and 'voice biomarkers' technologies?
"Voice biomarkers" technologies typically focus on isolated acoustic features (pitch, tempo, pauses) to detect specific conditions. While useful, they lack clinical context and struggle with the heterogeneity of real-world psychiatry—where patients have multiple diagnoses, varied treatments, and unique presentations.
Our Foundation Model takes a fundamentally different approach: it integrates voice with language, clinical history, and treatment context to build a comprehensive understanding of each patient. This transdiagnostic, multimodal design makes it robust to clinical complexity and capable of supporting diverse clinical applications—from symptom tracking to document generation—all from a single model. We're not just detecting patterns; we're providing contextualized clinical intelligence.
Are you still looking for research partners?
Yes. We actively collaborate with academic institutions, hospitals, and research centers to advance the science of AI in mental health care. If you're interested in exploring research collaboration, clinical validation studies, or data partnerships, please contact us at contact@callyope.com.
What data is your Foundation Model trained on?
Our model is trained on de-identified psychiatric clinical data, including consultation notes, patient-reported outcomes, voice recordings, and longitudinal clinical signals—spanning multiple languages and diagnostic categories. All training data is collected with appropriate consent and ethical oversight. We do not use patient data from our platform to train models without explicit agreement.
Can Callyope’s Foundation Model work in different languages?
Yes. Our model is trained on multiple languages and designed to generalize across linguistic contexts. This multilingual capability ensures consistent performance regardless of patient language, which is critical for diverse clinical populations.
What makes Callyope’s approach 'transdiagnostic'?
Rather than training separate models for depression, schizophrenia, bipolar disorder, etc., our Foundation Model learns patterns across the full spectrum of mental health conditions. This transdiagnostic design reflects clinical reality—where comorbidity is common and patients don't fit neatly into diagnostic boxes. It makes our technology more robust and generalizable than diagnosis-specific approaches.
How does the monitoring platform and app help me?
We help your doctor monitor your mental health between appointments with objective data. By tracking your symptoms continuously through our app, your doctor can detect early warning signs and adjust your treatment more precisely—leading to better outcomes.
Will you listen to my conversations all day?
No. You decide when and how your voice is analyzed. You can choose to record a voice journal entry, take a call with a trusted contact through our app, or participate in brief automated check-ins. All recordings happen only with your explicit consent
Can I use the app without a doctor?
No, our platform is designed to be used under medical supervision. It's a tool that helps your doctor provide better care—not a replacement for professional support. If you're interested, talk to your healthcare provider about using Callyope as part of your treatment.
Who can see my data?
Only your doctor and their authorized healthcare team can access your information.We never share your data with insurance companies, employers, or third parties without your explicit consent. Your mental health information stays between you and your care team.
How much time does it take each day?
Just 1-2 minutes. A voice journal entry takes 30 seconds, questionnaires take 1-2 minutes. You decide how often you check in—the app adapts to your routine, not the other way around.
