Get the most out of Luna AI

1. 1

   Create your account

   Head to the sign-up page. Enter your name, email, phone number and a password — it's free and no card is needed.
2. 2

   Add your phone number

   Luna uses your number to recognise you when you call in, so she greets you by name and loads your material. Keep it in international format, like +15551234567.
3. 3

   Check your welcome email

   You'll get a welcome email with Luna's number and ideas for your first conversation.

This is the fastest way to start — no app, no screen. Call or WhatsApp +1 (231) 879-5862 and Luna picks up and starts studying with you.

1. 1

   Save Luna as a contact

   Add the number to your phone so it's one tap away on a walk, drive, or commute.
2. 2

   Call from the number on your account

   Luna recognises your caller ID, greets you by name, and has your libraries and past topics ready.
3. 3

   Or call over WhatsApp

   The same number works for WhatsApp voice calls — handy internationally, since it uses Wi-Fi or data instead of a phone line.
4. 4

   Just say what you want to work on

   "Quiz me on chapter 3", "Help me practice Spanish", "Explain photosynthesis". You can also ask her to slow down, repeat, or give another example at any point.
5. 5

   Get a recap by email

   After the call, account holders receive an email with what you covered, what went well, and what to focus on next.

A Study Library is your own collection of material for a class, exam, or subject. Luna works through it with you on calls and web sessions.

1. 1

   Open the builder

   Go to Build Study Library from your dashboard.
2. 2

   Add your material

   • Upload full PDFs, textbooks, lecture transcripts, notes, or study guides — nothing gets cut short.
   • Snap a photo of pages or slides and Luna reads the text from the image.
   • Paste a link (articles, lecture pages) or a Quizlet set.
   • Type or paste text directly.
3. 3

   Long material becomes chapters

   Books and long documents are split into chapters, so you can tell Luna exactly which part to study instead of starting from page one every time.
4. 4

   Study it by voice or by phone

   Your libraries show up on your dashboard and are available the moment you call in.

You don't need to set anything up — just ask. Say "let's practice Spanish" and Luna switches into a real conversation at your level.

• Hold everyday conversations: ordering food, directions, small talk, interviews.
• Ask for corrections, slower speech, or a translation whenever you get stuck.
• Work on grammar and vocabulary out loud instead of tapping through exercises.
• Your progress is saved, so the next call picks up where you left off.

Every session is saved to your Study History on the dashboard, so you can see progress and pick up exactly where you stopped.

• Open any past session to read the summary, strengths, and next steps.
• Recap emails land in your inbox after phone calls.
• Your streak counts each day you study — short daily sessions keep it alive.
• Several short sessions on one topic beat one long cram.
• Delete individual sessions or whole libraries whenever you're done with them.

Luna is billed in study minutes rather than per feature — everything is included on every plan.

• Free — 20 minutes of study time every month, no card needed.
• Base, Plus and Pro — 60, 120 or 250 minutes a month.
• Minute boosts — top up with extra minutes any time you run low.
• Plan minutes reset each month. You can see what's left on your dashboard.
• Compare everything on the pricing page, and cancel from your profile whenever you like.

Visit your profile to tune the experience:

• Display name — how Luna greets you.
• Phone number — required so Luna recognises you when you call.
• Voice — choose the Luna voice you like listening to.
• Language — switch the interface via the globe icon in the navbar.
• Password & plan — change your password or manage your subscription here too.

• Study in short bursts. Two 10-minute calls beat one 40-minute cram. Use commute or walk time.
• Continue past sessions instead of restarting. Luna picks up where you left off — that's how one topic turns into real understanding.
• Tell her the chapter. With long uploads, naming the chapter or topic makes the session much sharper.
• Talk like a human. Don't recite textbook answers — Luna rewards understanding over wording.
• Ask "why". Say "explain that" or "give me an example".
• Set up on the web, review on the phone. Upload your material at a desk, then rehearse hands-free later.
