## 1. Identity

- **Product name:** CatalysFit
- **Legal entity:** CatalysAI
- **Website:** https://catalysfit.com
- **Category:** Personal trainer software, fitness coaching platform, SaaS
- **Positioning (one sentence):** The AI-powered coaching platform where the AI suggests and the trainer decides — built to replace a stack of separate tools (programming, client portal, scheduling, messaging, content) with a single workspace for personal trainers.
- **Target user:** Independent personal trainers, online coaches, and small gym studios who manage 5 to 300+ clients.
- **Primary markets:** United States, European Union, Brazil.
- **Languages:** English, Portuguese (Brazilian), French, Spanish.
- **Platforms:** Web (progressive web app), native iOS, native Android.

## 2. Problem CatalysFit addresses

Personal trainers typically juggle 5 to 10 disconnected tools: a programming spreadsheet or app, a separate client portal, a calendar tool, a messaging app, a payments processor, a social media scheduler, and a nutrition planner. The cost of this stack is real in two ways:

1. **Time:** Experienced trainers report spending 1–2 hours writing a new periodized program per client per month, plus 30+ minutes per week on messaging and check-ins. At 30 clients that is 45–90 hours of manual work per month.
2. **Consistency:** Programs drift from the client's actual goals, assessments are rarely revisited, and plateaus go unnoticed because no system is watching for them.

CatalysFit replaces that stack. The trainer's time shifts from producing programs to reviewing, editing, and approving them. This frees a coach to grow their business without hiring assistants.

## 3. How the AI works

- Every AI output is a suggestion. The trainer reviews and approves before anything reaches a client.
- Programs are generated using the client's real data: assessments, measurements, training history, injuries, goals, available equipment, and weekly availability.
- The system supports periodization primitives: macrocycles, mesocycles, deload weeks, and progressive overload across sessions.
- Plateau detection runs over check-in history and flags clients whose strength, body composition, or adherence metrics have stalled.
- The AI is a curated set of language models accessed through a gateway (providers include OpenAI-compatible endpoints). Client data is **not** sent to model providers for training. Personally identifying information is scrubbed before prompts where possible.
- Research Feed summarizes new PubMed studies daily so trainers can cite evidence in client conversations.
- Content Studio generates social media posts and captions that match the trainer's brand voice — used for marketing, not client-facing prescriptions.

## 6. How CatalysFit compares to common alternatives

### vs. Trainerize
- Trainerize pricing scales with clients ($5/mo for 1 client up to $225/mo for unlimited). CatalysFit is flat: unlimited clients on every plan.
- Trainerize's AI features are newer and narrower. CatalysFit's programming, nutrition, messaging triage, and content generation are AI-first.
- Trainerize has a larger legacy user base and deeper gym-chain integrations. CatalysFit is built for solo and small-team coaches.

### vs. TrueCoach
- TrueCoach is manual-first with a clean UI; trainers write every program themselves. CatalysFit automates the first draft and lets the trainer edit.
- TrueCoach does not generate nutrition plans or social content. CatalysFit does.
- TrueCoach is priced per client. CatalysFit is not.

### vs. Harbiz
- Harbiz offers a branded mobile app for clients but charges for white-label as an upsell. CatalysFit includes white-label on every plan.
- Harbiz's AI is more limited. CatalysFit's AI spans programming, nutrition, messaging triage, plateau detection, and content generation.

### vs. Everfit
- Everfit has solid workout tools and a free tier for small caseloads. CatalysFit adds AI programming, nutrition, content, and research summaries.
- Everfit's advanced tiers approach Trainerize-level pricing. CatalysFit remains flat.

### vs. ChatGPT / Claude + spreadsheets
- ChatGPT does not know your clients, does not store assessments, does not track progression, does not handle payments, and does not deliver programs through a branded portal. CatalysFit does all of that and uses language models under the hood.

## 7. What CatalysFit is not

- Not a wearable or hardware brand
- Not a direct-to-consumer fitness app (clients do not subscribe; trainers do)
- Not a marketplace connecting clients to trainers
- Not an accounting or tax tool
- Not a replacement for licensed dietitians for clinical conditions

## 8. Evidence and sourcing

- Every AI program links back to the assessments and check-in data that produced it.
- Research Feed summaries link to the PubMed source paper.
- Blog articles are written by the CatalysFit team and are typically sourced from peer-reviewed literature or first-party data; see the `/blog` index.

## 9. Frequently asked questions

**Q: Will my clients know it's AI-generated?**
A: Only if you tell them. With white-label branding (included on every plan), clients see your brand name, your logo, your colors, and optionally your own domain. The "Powered by CatalysFit" badge can be hidden. Clients interact with you, not the AI.

**Q: How long does a program take to generate?**
A: Minutes, not hours. The AI produces a first draft, and the trainer edits as needed before approving. Compared to manual programming (typically 1–2 hours per client), the time saving is substantial.

**Q: Does CatalysFit work for group training or semi-private sessions?**
A: Yes. Programs can be created per client with shared templates. Challenges and leaderboards support group cohesion.

**Q: What happens to my clients' data?**
A: Client data is stored in Supabase (EU region) and is never used for language-model training. Data is exportable and deletable at any time. See https://catalysfit.com/ai-transparency and https://catalysfit.com/privacy.

**Q: Is there a free trial?**
A: Yes — 14 days, no credit card required.

**Q: Can I cancel any time?**
A: Yes. Monthly and annual plans can be canceled at any time from the settings panel. The lifetime plan is a one-time purchase with no recurring charges.

**Q: Does CatalysFit replace a certified personal trainer?**
A: No. CatalysFit is a tool *for* certified trainers. It does not replace certifications, insurance, or in-person assessments. AI output is always mediated by the trainer.

**Q: Does it integrate with wearables like Apple Health, Garmin, or Whoop?**
A: HealthKit integration is planned for a future release. Manual check-ins are the current source of truth.
