What is a Point of Knowledge (PoK)?

A Point of Knowledge (PoK, pronounced "poke") is one focused thing you're trying to learn. A concept, a chapter, a lecture, a paper. Ritsu builds your study session around it.

Why PoKs

Most "AI learning apps" treat every question as standalone. You ask, you get an answer, you forget where you were. Ritsu doesn't work that way.

When you have an active PoK, every command runs in that context:

• /explain explains a concept as it relates to your current PoK
• /quiz tests you on the PoK, not the entire universe
• /flashcard makes cards scoped to the material you actually care about
• Your progress, notes, and decks all live under the PoK

It's a small idea with a big payoff. Once Ritsu knows what you're studying, every interaction gets sharper.

Where PoKs come from

Three ways:

1. From a source — upload a PDF or import a YouTube video, and Ritsu extracts PoKs automatically (one per chapter, section, or topic).
2. From a plan — describe what you want to learn ("React hooks in 7 days") and Ritsu builds a sequence of PoKs.
3. Manually — type one in. Useful for ad-hoc study.

Switching between PoKs

The PoK switcher lives in the top of the chat sidebar. Switching takes one click. Your chat history, deck progress, and notes are scoped per PoK so context never bleeds between subjects.

What PoKs are NOT

• They're not folders. You can't nest PoKs.
• They're not flashcard decks. A PoK can have many decks.
• They're not the same as a source. One source can produce many PoKs.
