Mentible (repo StudyBuddy_SelfLearner)
A purpose-built LLM client for self-learners — turn a scoped query into a real,
polished book (EPUB3/PDF). ("StudyBuddy Q / Q = Query" is the historical name;
the public brand is Mentible — ADR-006, pending trademark clearance.)
Repo: StudyBuddy_SelfLearner (internal name). Brand: Mentible (public-facing).
Status (2026-06-27): in production. Backend live at mambakkam.net/mentible-api;
full web app now at its own canonical domain https://mentible.app/ (also still
served at mambakkam.net/app/mentible); read-only demo at /demos/mentible;
Android APK released. Accounts (Supabase) + super-admin verified live.
Current "what's built" record → docs/STATUS.md.
What is this?
A focused, opinionated mobile client on top of the Anthropic API. Adults paste
their own Anthropic API key (BYOK), describe what they want to learn, and get
a beautifully rendered lesson, explanation, or quiz back.
Not a chatbot. Not a course platform. Not a children's product.
Think "Claude Code, but for learners instead of coders."

Quick links
Key constraints (read these before any code lands)
- BYOK — User pays Anthropic directly. We never store keys.
See
docs/adr/ADR-001-byok-security-model.md.
- Vendored pipeline only — Never import from
../StudyBuddy_OnDemand/.
See docs/adr/ADR-002-repo-structure-and-vendoring.md.
- Adults only — No COPPA, no FERPA, no school logic.
- Quality over scale — This is a demo of the IP, not a mass-market consumer play.
Sister project
StudyBuddy_OnDemand — the institutional B2B product
for schools. Different audience, different compliance, different infra. Shares
prompt IP via vendoring (one-way), nothing else.
