Understand the Coach
How FastSnap works
Snap → Coach’s Call → memory. Why FastSnap doesn’t count calories and how Behaviour OS remembers your decisions.
FastSnap is an AI meal coach for people improving body composition. The loop is simple on purpose.
The loop
- Snap the meal.
- Get one Coach’s Call — and why.
- Make the better decision at the table.
- Come back. The coach remembers.
Why we don’t lead with calories
Calorie diaries optimize logging. FastSnap optimizes the decision. Macros can exist under the hood as scoring inputs; what you read is a call you can act on.
Memory is the moat
Recognition and continuity are not a scrapbook of meal cards. They are so the coach can say things only your week makes true — lighter lunch than usual, recovery from yesterday, protein holding.
Tell the Coach
When the photo is incomplete or the context matters, you can tell the coach. That improves the call without turning the product into a chat encyclopedia.
What FastSnap does
Every snap feeds a coach that remembers decisions over time — so week-three calls can be sharper than day-one calls on the same kind of plate. That is Behaviour OS as a product, not a blog topic.
