Objective:

To describe the development, deployment, and initial validation of Talkcast, an AI-powered tool aimed at enhancing therapy outcomes through between-session reinforcement of therapeutic concepts.

Key Findings:

• 46.27% of active providers generated a Talkcast, indicating provider engagement.
• 12.97% of active clients received a Talkcast, with 52.70% opening it, suggesting client interest.
• Over 90% of providers rated Talkcasts as 'Helpful' for session reinforcement, highlighting provider satisfaction.
• 76.02% of clients rated Talkcasts as 'Helpful,' citing personalization and relevance, which underscores the tool's effectiveness.
• A significant positive association was found between opening a Talkcast and higher overall platform engagement, indicating its potential impact on therapy outcomes.

Interpretation:

Talkcast demonstrated promising feasibility and high acceptability among both providers and clients, suggesting it is a well-integrated blended care tool that aligns with existing literature on digital therapy aids.

Limitations:

• The study was retrospective and did not include couples therapy or psychiatry, which may limit applicability to these populations.
• Feedback indicated a need for improved content specificity and AI authenticity, which could enhance user experience.

Conclusion:

Future work should focus on establishing causality, refining the AI's content generation, and exploring its application in diverse therapeutic contexts.
