Your therapist asks how last week went. You remember a feeling and maybe a couple words. Some people call it therapy amnesia. MindSync keeps the rest. Talk or type for a minute after a session and it becomes a card: topics, questions, to-dos, realizations. The day before your next session, a Prep Card sums up what came up since last time, so you walk in knowing where to start. "I love how the AI feature organizes my notes and thoughts to help me figure out what comes up most often... so I know what to work on with my therapist." Grace O., therapy client HOW IT WORKS After a session: a one-minute recap, by voice or text. Or record the session, if your therapist agrees. MindSync tells the two voices apart where it can and writes the summary. Either way, the card shows your progress since the last session. Between sessions: leave a voice note when something comes up and MindSync transcribes it. Talk it through with Orca, the app's AI assistant, in Reflect. Themes that keep coming back get their own thread. The app suggests, you decide. Before the next session: a Prep Card appears on its own, with what to raise and what you promised to try. HOMEWORK, AGENDA AND EVERYTHING YOU SAID Workspace holds the agenda for your next session, your goals and your to-dos, with homework from your therapist and action points from Orca in one list. Timeline keeps every entry in order. Share any card with your therapist as an image. "My patients come in prepared. We spend the session working, not recapping." Kate (therapist) SEE WHAT'S CHANGING Change is hard to see from the inside. Your Character page shows it: six strengths (Courage, Insight, Honesty, Resilience, Kindness and Commitment) grow each time they show up in what you share. If a line doesn't sound like you, tap "Not quite" and it stops counting. - Focus Areas: rate sleep, worry or anything else from 1 to 10 and read the trend in plain words. - Habits you want to keep, and habits you want to drop. - A check-in on how it's going with your therapist. - Weekly and monthly summaries that show the pattern you'd miss day to day. "I tend to second-guess myself, so seeing my progress on a chart is reassuring. I no longer say maybe." Tomek (CBT) MEET ORCA Orca is MindSync's AI assistant for the days between sessions. It's software. It doesn't replace your therapist; it helps you remember and prepare. A psychologist on the MindSync team reviews how Orca is designed to respond. In Settings you can see everything Orca remembers and delete any of it. WHY KEEP YOUR OWN RECORD A week after a session, people in one study recalled only a fifth to a third of what their therapist had covered. Across 58 studies, tracking progress in therapy meant slightly better results and fewer dropouts. MindSync gives you a record to bring in, not medical advice. PRIVACY Your data is encrypted in transit and at rest (AES-256). MindSync deletes the audio from voice notes and recordings as soon as the transcript exists. There are no ads, and MindSync never sells your data. You can delete any entry, or your whole account, whenever you want. FREE TO START Four days of Premium, free. No card needed, and it ends without charging you. After that, the Free plan gives you a few cards, voice notes and Reflect messages each month, plus a couple of session recordings. Premium lifts those caps and adds voice talks with Orca. Cancel anytime in your App Store settings. Try it before your next session and walk in knowing where to start. MindSync isn't a crisis service. If you're in danger, call your local emergency number. In the US, you can call or text 988 any time, or 911 in Europe.

Supplemental Capture insights. Stay engaged between sessions. Walk into therapy prepared. Supplemental is a therapy companion that helps you capture insights, prepare for sessions, and build small daily practices—so progress doesn’t stop when therapy ends. Most people leave therapy feeling clear and motivated. By the next day, life gets busy. Important thoughts are forgotten, breakthroughs fade, and the things you meant to discuss never make it into your next session. Supplemental helps you hold onto what matters. Capture Before You Forget Record thoughts, emotions, breakthroughs, patterns, and questions the moment they happen using voice or text. Everything is automatically organized, so your reflections are ready whenever you need them. Walk Into Therapy Prepared Build a Session Agenda naturally throughout the week instead of trying to remember everything at the last minute. Before your appointment, generate a clear Session Brief that organizes your themes, challenges, wins, and priorities into one easy-to-read summary. Spend less time remembering. Spend more time making progress. Turn Insight Into Action After therapy, transform your biggest takeaways into personalized daily micro-practices inspired by evidence-based approaches including CBT, DBT, and mindfulness. Small actions. Real momentum. Stay Connected Between Sessions Growth doesn’t happen one hour a week. Use reminders, guided reflections, and simple daily practices to stay connected to the work you’re doing long after your therapy session ends. Supplemental Pro Unlock advanced therapy tools including: • AI-generated Session Briefs • Personalized Micro Practices • Insight Mode • Smart reminders Designed to Support Therapy — Not Replace It Supplemental is designed to complement your work with a licensed mental health professional. It helps you remember what matters, prepare for meaningful conversations, and apply therapeutic insights between sessions. Supplemental does not provide medical advice, diagnosis, or treatment and should not be used as a substitute for professional mental health care.
