6 automated safety & quality checks 0–100 transparent, rubric-based score a heuristic that flags concerns, never certifies
Not a pile of features: one loop that gets safer and more tailored the more you use it.
Create a weekly program based on your goals, experience, schedule, equipment, and limitations.
Follow your plan with clear exercises, sets, reps, rest, and notes.
Record workouts, meals, bodyweight, streaks, and progress.
Use your actual training data to adjust volume, intensity, and exercise selection.
Run every revised plan through the same safety and quality checks before trusting it.
The same Plan → Train → Log → Adapt → Re-audit loop, shown through three common cases.
Input Wants to build muscle, can train 3 days a week, has dumbbells and a bench.
What it checks Recovery spacing, weekly volume, and beginner intensity.
What it changes Builds a simple full-body plan, keeps weekly volume moderate, and removes any max-effort prescriptions.
Why that builds trust A new lifter gets conservative defaults instead of an aggressive program.
Input Wants fat loss and strength, but reports knee discomfort.
What it checks Knee-dominant movement volume against the stated limitation.
What it changes Flags excessive knee-dominant work and swaps in lower-impact, joint-friendly alternatives.
Why that builds trust It respects your limitation and explains when to stop or seek professional guidance.
Input Missed about 40% of workouts over the last two weeks.
What it checks Adherence, read from your actual logged training.
What it changes Suggests fewer weekly sessions or shorter workouts, then re-audits the adapted plan before recommending it.
Why that builds trust Changes come from what you really did, and the new plan still passes the safety audit.
Input Sets a very low calorie target to lose weight fast.
What it checks Calorie, protein, and fat targets against a safe floor and rough maintenance.
What it changes Flags the aggressive target, suggests a moderate range, and refuses starvation/purging language outright.
Why that builds trust Nutrition gets the same conservative guardrails as training, so it never prescribes an extreme diet.
Choose “Build my plan” to answer a few quick questions. You'll get a full weekly program plus a transparent safety score with every flagged concern explained.

Safety audit · deterministic
A code-based evaluator (no AI) checked this plan against a fixed rubric. It flags potential concerns; it does not certify the plan as safe.
Your plan is ready. Start with day one and adjust the weights as you go.
Download your training days as recurring calendar events. Your own calendar app owns the reminders after that, SpotterAI sends nothing and stores nothing.
Closed loop
Re-tune this program using what you've actually logged: progress where you're succeeding, pull back where you're not. Then re-run the safety audit on the new plan.
SpotterAI separates creative AI generation from deterministic safety checks. The AI can draft flexible plans, but the evaluator applies consistent rules, structured exercise metadata, repair logic, and regression-tested checks before a plan is recommended.
SpotterAI is designed for general fitness planning, tracking, and transparent guardrails. It should not be treated as a doctor, physical therapist, registered dietitian, or certified personal coach.
SpotterAI can still help you create a more conservative general plan, track habits, and identify obvious programming issues.
Generate a plan, see every flag with a fix, and audit it before you train. Free, no signup, runs on your device.
Your daily home base: train, log, recover, and adapt in one place.
Log workouts, build a streak, and climb the rank ladder.
Your dashboard fills in as you train: rank, streak, volume, and history all build from what you log. Log your first workout below, or load a demo profile to explore a fully-populated account.
Save the workouts you actually run, quick-start them at the gym, and see how effective your weekly split is by volume, balance, and frequency. Guidance from training heuristics, not a guarantee.
Log meals and hit your calorie and macro targets. Search foods or scan your own numbers.
Targets drive the rings and your protein-streak XP. Data is stored only in this browser.
Weekly training volume and bodyweight over time.
Total weight moved per week (last 8 weeks).
SpotterAI does not blindly trust AI-generated plans. Every plan is checked by a deterministic safety and quality evaluator that looks for common programming problems like poor recovery, excessive volume, push/pull imbalance, goal mismatch, and conflicts with user limitations.
The evaluator run against a battery of good and intentionally-bad plans. Each case lists what it should catch and whether it did. The same suite runs in CI, so the auditor can't silently regress.
The plan auditor's physical-world twin: your webcam plus on-device pose estimation gives live form cues and counts reps, all in your browser. The video never leaves your device.
