WithMarsha

What the service is

WithMarsha is an AI-driven app designed to reinforce Dialectical Behavior Therapy (DBT) skills between therapy sessions. It is built explicitly as a supplementary tool, not a replacement for therapy with a qualified mental health professional. The app runs on iPhone and iPad and is available through the Apple App Store with optional subscriptions managed through Apple's in-app purchase system. The company developed the app as an "educational application for learning and practicing DBT skills," deliberately stepping back from claiming clinical status.

How the app works

WithMarsha guides you through DBT practice using four core skill pillars: Mindfulness, Emotion Regulation, Distress Tolerance, and Interpersonal Effectiveness. The mechanics are straightforward: you describe what you are experiencing in the moment, and the AI companion (named Marsha, inspired by DBT's creator Dr. Marsha Linehan) surfaces the most relevant skill from a structured library and walks you through how to practice it. The company describes this as "a DBT workbook that knows where to open": the AI selects and navigates to the right page based on your input rather than you having to find the right skill yourself.

The app is designed for daily practice and regular engagement between therapy sessions. You can use it to practice skills when emotions spike outside the therapy room, when homework from your therapist comes due, or simply to build a practice rhythm as part of your ongoing mental health work. The app works through a conversational interface, making it feel like ongoing guidance from a coach rather than reading static content or worksheets.

Importantly, the company is explicit about what the AI does and does not do. Marsha "does not assess your mental health, adapt a treatment plan, or intervene in a crisis." When you describe what you are experiencing, the AI selects the most relevant skill from a fixed psychoeducational content library and explains how to practice it. It does not diagnose any condition, provide clinical treatment, or change your treatment plan. The app's FAQ reinforces this: "Marsha does not assess your mental health, adapt a treatment plan, or intervene in a crisis. When you describe what you're experiencing, the AI selects the most relevant skill from a fixed psychoeducational content library and explains how to practice it."

What the captured pages establish

WithMarsha was developed by GTM Bot Inc., though it is inspired by the work of Dr. Marsha Linehan, the psychologist who created Dialectical Behavior Therapy. The company is clear about the relationship: "WithMarsha is inspired by the work of Dr. Marsha Linehan, creator of Dialectical Behavior Therapy (DBT), but is not affiliated with or endorsed by her or the Linehan Institute."

The company commits to evidence-based content: "Our public DBT content follows a source-led editorial process using DBT manuals, peer-reviewed research, and official clinical resources." This means the skills library draws from published clinical material rather than the company's own interpretations.

The app emphasizes data privacy. The company states: "Your conversations and personal data are encrypted and stored securely. We never sell your data to third parties. You can delete your account and data at any time." The FAQ elaborates: "Your data is encrypted and we do not share your data with third parties."

Availability is currently limited to iOS: the company states "WithMarsha is available now for iPhone and iPad. Android and web availability will be announced only when those versions are ready," indicating that Android and web versions are in development but not yet available. Subscriptions are managed through Apple's standard App Store purchase system with optional subscription tiers, though the exact pricing and trial availability vary by region according to the App Store.

What the service does not say

WithMarsha does not publish sample skill modules, lesson plans, or example practice sessions that you can review before purchasing a subscription. You cannot see exactly what the skills library contains or how the AI responds to specific situations without downloading the app and exploring it yourself.

The pages do not specify pricing in USD or any specific currency or region. They direct users to the App Store for "current pricing and trial availability for your region," meaning you must use the Apple App Store to see the exact cost in your country. The company does not state whether there is a free version with limited features, a free trial period, or if subscription is required from the start.

The company does not specify how much daily or weekly practice the app expects or what timelines are realistic for seeing improvements. It does not detail how long the app stores your practice history, how much data a single user typically uses, or whether you can export your progress data or share it with a therapist. There is no information about age limits: WithMarsha's pages do not state whether the app is suitable for teenagers, young adults only, or all ages.

The company does not provide information about accessibility features, language support, or whether the app is optimized for assistive technologies. It does not specify compatibility with older versions of iOS or older devices.

Who it fits and who it does not

WithMarsha fits someone already working with a therapist on DBT, particularly someone in a DBT skills group or individual DBT therapy. If your therapist assigns homework or between-session practice, this app provides a structured place to do it. Someone who learns through interactive guidance rather than reading static worksheets will find the conversational AI interface more engaging than a PDF worksheet.

It also fits someone in a part-time or self-guided DBT track where they are learning the skills without formal therapy but want structured support and practice reminders. The company explicitly compares WithMarsha to other options: "WithMarsha vs DBT groups / Decide whether you need weekly live groups, an app, or both," acknowledging that some people benefit from combining an app with group therapy.

WithMarsha does not fit someone in acute crisis. The company states clearly: "WithMarsha is NOT an emergency service. If you're in crisis, please call 988 (Suicide & Crisis Lifeline), text HOME to 741741, or call 911." This is an app for ongoing maintenance and skill-building, not crisis intervention.

It does not fit someone who needs clinical assessment or treatment planning. The AI does not adapt based on your specific diagnosis or change your care plan. It does not fit someone who prefers working entirely with a human therapist and worksheets over digital apps. It does not currently fit Android users or people who exclusively use web platforms: the app exists on iOS only.

It does not replace therapy. The company reinforces this: "No. WithMarsha is an educational tool designed to help you practice DBT skills, but it is NOT therapy or a substitute for professional mental health care."
