Jana is a personal AI tutor and study companion for adults aged 18+, including university students and independent learners. It helps learners work through their own materials, explain their reasoning and practise towards independence, carrying useful context across sessions.

A persistent conversation draws on saved preferences, attempts, progress and materials. Learners can inspect, correct or forget memory, stored on the device by default with separate controls for online use.

The Study workspace connects explanations, concept maps, source references and quizzes. Our demo uses a university psychology lecture from MIT OpenCourseWare: a learner confuses classical and operant conditioning, attempts a question and checks the explanation against the original lecture. Generated study materials undergo citation-location validation and a separate source-support check.

Jana supports guided problem-solving through text, speech and photographed working. Computational tools check supported calculations and units; photo outlines and diagram exercises make visual feedback specific to the learner’s work. Teaching features include prerequisite-gap tracing, explain-it-back checks and prediction-based simulations. Authored O-level Mathematics, Physics and Chemistry packs provide structured foundational learning alongside study from learners’ own materials.

The companion connects study, research, planning and progress. A research agent agrees a brief before assembling cited material; transcript-linked lecture study connects ideas to video timestamps; a progress map shows learning history.

Installed lessons, practice and saved materials remain available offline. With Muse Glimmer installed on suitable hardware, Jana also supports local AI tutoring. The README explains setup and current reliability limits, distinguishing saved offline study from new model replies.

Hackathon development began on 26 October 2026, building on a baseline imported on 25 October. The README’s “Hackathon contribution” section explicitly separates pre-existing work from additions made during the hackathon, supported by dated implementation commits. These additions include teaching features, the personal Study companion, research, lecture study, learner progress maps, voice and local inference, plus the demo’s document concept maps, original-PDF reader and rebuilt quiz interface. Earlier material-import, marking, learner-memory and local-storage foundations are identified as pre-existing work.
