Synthesis helps parents log how their child with ADHD or other diagnoses is doing by voice, in seconds, even on the hardest days. Speak for 30 seconds about your child's day. Synthesis transcribes your observation on your phone, structures it into a clear log entry, and after a few days surfaces specific patterns like a mood dip in the 3–5pm window on 4 of the last 7 days. You already know your child better than anyone. Synthesis helps you prove it with a record you can bring to your next appointment. WHAT YOU CAN DO • Log by voice, speak instead of typing • Track doses, mood, sleep, focus and appetite • See patterns you'd never spot alone, surfaced automatically • Build a trend report from your real observations • Review the week at a glance on a 7-day timeline PRIVATE BY DESIGN • Your voice is transcribed on your phone, audio never leaves the device • Only the text of your observation, with your child's name removed, is sent for analysis • Your logs are encrypted on your device and are never used to train AI • You decide what your doctor sees, reports stay private until you share them Synthesis is a general wellness and tracking tool. It is not medical advice and is not a substitute for professional care. Always consult your child's healthcare provider about medication decisions.
