Frequently Asked Questions

S-TIER.AI is the software strength coaches run their business on. Write or import a program, assign it to a client, and it adapts to the equipment in that client's gym. You get their logged sessions, PRs by equipment variant, and roster-wide activity back — all powered by AI.

Coaches who program strength, hypertrophy, and powerlifting for clients — that's who we build for first. Athletes can also run their own training on it, whether in a home gym or a commercial facility, and either way S-TIER.AI adapts the program to the equipment actually on hand.

Neither. S-TIER.AI is a tool that helps you organize and adapt existing training programs. We do not prescribe workouts, provide medical advice, or replace a qualified coach or healthcare professional.

Paste your program text or upload files (PDF, Word, photos), and our AI reads the content and converts it into a structured program with exercises, sets, reps, and rest periods. It then matches exercise names to our database of 170+ exercises with full muscle-group and equipment mappings.

Files are processed in memory by our AI service provider (Anthropic) and are not permanently stored after parsing is complete. See our Privacy Policy for full details.

The AI handles most standard program formats well, but it can make mistakes — especially with unusual formatting or handwritten notes. Always review the parsed output before saving. You can manually correct any exercises, sets, or reps that were parsed incorrectly.

The Coach plan includes 200 AI parses per month and Coach Pro includes 500. The Athlete plan includes 10. Limits reset on the 1st of each month. Unused parses do not roll over.

When an exercise in your program requires equipment you don't have, S-TIER.AI suggests alternatives that target the same muscle groups and movement patterns using the equipment available at your selected gym location. Substitutions are ranked by how closely they match the original exercise.

Yes. Go to Settings > Exercise Preferences to exclude specific exercises. Excluded exercises won't appear as substitution suggestions.
