PRD — Cetking One
Vision
Cetking One is a learning home — an online ashram — for CAT / MBA-entrance students. Not a course platform with a chatbot on top. Six AI companions ARE the product domains. A student comes to hang out with them and grow.
Indians hate helpers; they want to do it themselves. So the companion is the tool, not an assistant bolted onto it.
Who it is for
- Students preparing for CAT, CET, SNAP, NMAT, CMAT and other MBA entrances (existing Cetking students and new visitors).
- Staff use a separate back-office (CK Backoffice MCP, /admin). Staff do not get a companion persona.
The six companions
| Companion | Internal label | Owns | Look |
|---|---|---|---|
| Oracle | Home | Home host. Sees everything, owns nothing. Welcome, morning nudges, stories | Indigo-violet #4029cb round blob, friendly face (was pink) |
| Rocky | Mocky | Mocks (TCY), mock strategy videos | Light blue #66b3f7 clay blob |
| Arena | Arena | Arena / War Room leaderboard (was "Luna", briefly "Mishika"; "Arena" is already a famous name) | Red #d90429 oval blob |
| Guruji | Classes | ALL teaching: live classes, recordings, concept videos, shortcuts | Yellow #fbc815 tilted-egg blob |
| Sutra | Booksie | Books, formulas, study, reading tracker | Purple #8b5cf6 teardrop blob |
| Purva | GDPI | Admissions, GD-PI, SOP, deadlines (was "Pandit" until 3 Oct 2026) | Orange #f97316 cloud blob |
Students rename each companion at onboarding. Analytics is a shared service inside every bot, not a bot.
Principles
- Companion IS the feature (Rocky is mocks; Arena is Arena).
- SEO pages, blogs, videos and shops are formats owned by a bot (bot_owner tag), not a separate site.
- Oracle gives the student a whole-brain view: mocks taken, books reached, classes attended.
- Playful, never preachy. When something breaks, show a cheeky in-character X with an alternative.
- Mobile first.
Phase 1 (strangler-fig): wrap what exists
TCY mocks (SSO + score return), War Room, Dyntube videos, class content, admissions data, OTP login. Phase 2 adds AI gradually.
Success measures
- Students come back daily (Oracle nudges).
- Public pages rank on Google (migrated WordPress URLs preserved).
- 99.5% uptime. Cost target about $100–220/month at ~1000 users (700 free, 300 paid).
