Synapse's coach runs entirely on your device using Apple Intelligence. It knows your real study data — what's due, what's slipping — and can also explain concepts and suggest study plans. Here's how to get the best out of it.

Open the coach
Tap the floating coach button (the speech-bubble in the bottom-right corner) — it's on every tab. The chat opens anchored right above it and keeps context across the conversation, and it scopes to wherever you are: study data on Study, questions on Practice.
The coach floats bottom-right on every tab.
Ask about your own progress
This is where it shines — it answers from your real numbers:
“What should I study today?”
“Which subject is my weakest?”
“How many cards do I have due right now?”
“Am I keeping up, or falling behind?”
Tip:Focus a subject first, then ask — the coach scopes its answer to just that subject.
Ask general study questions too
The coach isn't limited to your data. Ask it to explain a concept, plan a schedule, or point you to resources:
“Explain the difference between SN1 and SN2 reactions.”
“Build me a 6-week study schedule.”
“How should I structure my flashcards?”
Get help using the app
Stuck on how to do something? Just ask — “How do I import a deck?” or “How do I focus a chapter?” The coach knows its way around Synapse and will walk you through it (or point you to the full guides).
Private by design. The model runs on your device — your study history never leaves your iPhone or iPad, there's no account, and it works offline. (The on-device coach needs a device that supports Apple Intelligence; everything else in Synapse works without it.)
Double-check the important stuff. The coach is an on-device AI and can occasionally be wrong on facts. Use it for guidance and explanations, but verify anything exam-critical against a trusted source.
