Study Assistant

Needs Ollama running at localhost:11434. While active, questions never go through the Learnitas server at all, and vault search (RAG) is disabled. If you hit a CORS error, run Ollama with the env var OLLAMA_ORIGINS=*.

Ask about anything in the vault — I'll search the notes for you rather than guess.

Knowledge graph Flashcard review

Changes how the Study Assistant explains things to you — applies immediately.

Which cloud AI answers References, Related resources, Translate, and Study Assistant (hosted mode — not local-Ollama mode below). Picking Gemini or Claude specifically uses only that provider; if it can't answer, you'll get an error rather than a silent switch.

Toolbar icons

Hide the ones you don't use. Applies immediately, remembered on this device.

Drawing, annotation, and the reading canvas.

Turns on the pen toolbar over any note, for drawing with a stylus or finger.

Hides everything but the note and splits it into turnable pages. The pen lives behind the brush button in the top-right; "Exit" next to it brings the rest of the app back.
