AI Companion for Students

A study companion that actually remembers what you are studying

Why students need a different kind of AI

ChatGPT forgets you exist between sessions. Quizlet does not actually understand the material. Tutors are expensive and not available at 2am.

How Luna fits

Luna holds the full arc of your courses — what you have covered, what is hard, what your finals are and when. She explains, drills, builds practice tests, and adapts to how you learn.

Persistent memory of every course, every concept you are stuck on, every test date
Generate practice tests from your own notes — Luna reads them and quizzes you
Voice mode: she explains a topic and asks if you got it, like a patient tutor
Heaven Code Studio: build the demo app your CS professor asked for in one prompt
Free forever on iOS, Android, Web and Mac — no credit card to start

Start with Luna

Luna is free, available on every device, and built to remember you. Open the web app and say hi — she will pick up where you leave off, on every device you sign in on.

Frequently asked

Is Luna actually built for students?

Luna is built as a general-purpose sovereign AI companion, but her architecture — persistent memory, voice mode, no-judgement design, free tier — happens to map exceptionally well to what students need from an AI. She is not a re-skinned chatbot; she remembers you across every device and every conversation.

Is Luna private?

Yes. Luna runs on the Heaven Quantum Cortex — Heaven Eco Hub's own model stack — with no third-party LLM (OpenAI/Anthropic/Google) in the hot path. Your encrypted Memory Pod is end-to-end secured and yours alone.

Does Luna cost anything?

Luna is free forever on iOS, Android, Web and macOS. An optional Chip subscription ($1.99 / month) unlocks 500 welcome tokens, unlimited persistent companions, and priority routing.

Can I use Luna offline?

Partially. Heaven Code Studio includes an in-browser local LLM (WebGPU) for offline inline completions. Full conversational mode currently requires connectivity, with offline expansion on the roadmap.

What devices does Luna run on?

iOS, Android, Web (luna-heaven.web.app), and macOS. The same companion follows you across every device with cross-device Memory Pod sync.
