Strength coaching that evolves with you
You mentioned your knee once. It never forgot.
It remembers the injury you mentioned in passing, the lift you said you hated, and the goal you set in March — and builds your training around what it knows. You never re-explain yourself.
iPhone. In private beta — currently on TestFlight with a small group. Join the list and we’ll send you an invite as we open it up.
You’ve explained yourself to four different apps.
Every one of them asked for your goal, your equipment, and your injuries during onboarding. Then none of them ever brought it up again.
So you keep doing the accounting yourself. Remembering that the 5×5 template doesn’t know about your shoulder. Remembering to knock the volume down after a week off. Remembering which lift has been flat for two months. The app tracks; you coach.
That’s backwards, and it’s the reason most people quietly stop opening these things.
Asked once. Never used again.

- Your equipment
- Your injuries
- The shoulder
- The week off
- The lift that’s been flat
Sett keeps a running set of facts about you — what your body can’t do, how you like to train, what you’re chasing, what you’ve hit. It writes them down as you mention them, not from a form.
That’s the point of an AI coach: it can hold every set you’ve ever logged and every thing you’ve ever told it — and it never forgets.
What it remembers
You said it once, in the middle of a set. That was enough.
You never see it happen. It keeps what mattered — a knee that doesn’t like depth, a lift you’re chasing, a movement you refuse to do — and it never asks you to fill anything out to get there. Then it just quietly builds around it.
Most of the time you won’t notice. That’s the point. Here’s the day you do.

- You
leg day. going heavy today
- Coach
Leg day’s up. I’ve got you on box squats to parallel, trap bar deadlifts, and split squats — heavy is fine, I’m just keeping you out of deep knee flexion.
- You
why? I feel fine
- Coach
Your right knee. You told me it was bothering you on deep squats and I’ve been working around it since. If it’s been quiet lately, say so and I’ll open the range back up.
- You
...I don’t even remember telling you that
- Coach
It’s in my notes. Want me to drop it, or hold it one more cycle and see how the box squats feel first?
- You
hold it.

Body & Limits
IllustrativeRight knee pain on squats — avoiding deep knee flexion for now.
You can see everything it’s learned about you, grouped and dated, in one screen. Anything you don’t want it holding onto, you delete — and it won’t quietly relearn the same thing next month.
It never volunteers what it remembers. It won’t open a session reminding you about your knee, and it won’t tell you what you said and when. It just uses it, and tells you why when you ask.
Mid-workout
Someone’s on the rack. Say so.
Sett is with you while you train, not just before. The machine’s taken, the weight feels wrong, you want one more round — say it the way you’d say it to a person. Type it, or hold to talk; dictation runs on your phone.
- Swap the barbell rows, someone’s on the rack.
- 225 for 5, that was an 8.
- I did 5×5 at 185, then a back-off set at 165.
- Add face pulls after this.
- Move squats to the end.
- Give me one more round.
- What am I doing next?
It can log several sets at once.Finish a block, say “I did 5×5 at 185 then dropped to 165 for a back-off set,” and it writes all six rows — weight, reps, and how hard it felt.
Every one of those changes the workout in front of you. It doesn’t get filed as a note for later.
The programming
The plan is boring on purpose.
Progressive overload, real training maxes, scheduled deloads. Nothing about the programming is improvised.

It progresses because the program progresses — not because it felt like it.
Every program in the library carries its own real progression engine — and the library is a ladder. Sett Comeback ramps you back after time off with RPE-capped weeks, graduates you into Sett Foundations’ linear progression with stall detection, and that hands you to Sett Progression’s GZCLP stage ladder with the training-max reset when you stall. Not a list of workouts with a name on top.
Your training maxes are tracked across cycles. On Sett Progression you can see the forward projection — what next month looks like if you hit your targets.
Weights come from your logged sets, not a formula about your bodyweight.
When a session starts, the weight it puts in front of you is built from what you actually lifted last time on that exact movement — your most common working weight and reps, adjusted for how long it’s been. Two weeks off drops it about 10%. Back inside a week and your last sessions felt easy, it nudges up. Each suggestion carries its reason in plain words.
New lift with no history? It starts you with a conservative estimate that says it’s an estimate, and it sharpens from the first set you log.
Your injuries come out of every workout it builds — not just mentioned to the coach.
The movements you flag in your profile — overhead pressing, back squats, deadlifts, jumping, deep knee flexion, spinal loading, running — map to movement patterns that get removed from the exercise pool before anything is built for you: the program you’re running, the one-off session you ask for on the spot, and the swap you call for mid-set. It isn’t the coach remembering to be careful. The exercise never reaches it.
It knows what you’ve trained. All of it.
Eighteen muscles, tracked off every set you’ve logged in the last seven days — volume, effort, and how long ago, on a curve that adjusts to your age. Not a readiness score: an honest ledger you can open. Which muscles did the work, which exercises did it. Trained chest hard two days ago? Today leans somewhere else.
Your numbers
Ask how you’re doing. It answers with your numbers.
how am I doing on bench?
Not a canned dashboard reply — the coach reads your actual history and answers like someone who’s been watching: your estimated max, your best real set, what’s moved in the last month.
Records that show their work.Estimated 1RM beside your best logged set — the date, the weight, the reps behind every number. Strength, reps, and holds each get their own kind of record.
Loud when you earn it.Beat a best and the recap says so — BENCH PRESS 171 → 204 ▲ +33 lb · NEW HIGH — for weighted lifts and bodyweight work.
Quiet when you don’t. A lift running under its trailing best gets a small inline note on the recap. Never a headline, never a guilt trip.
It notices the layoff. First session back after ten days off, the volume comes down and it tells you why: “your first session back — I dialed it back so soreness doesn’t sideline you.”
A month, written up.A monthly recap in the coach’s voice — what you pushed, what moved, what it noticed.
It notices the comeback, the plateau, the lift you’ve quietly stopped doing — and brings them up like a coach, not a notification.
Stop re-explaining yourself.
