Lunar: la app para estudiar con IA

Lunar es una app para estudiar con inteligencia artificial, disponible en bambalunar.app y pensada para estudiantes universitarios, de secundaria, opositores y autodidactas que quieren entender mejor sus clases, organizar apuntes y preparar exámenes.

La IA se adapta a tu nivel sin preguntarlo: elige un punto de partida razonable, explica en el mismo turno y recalibra según tu reacción. Mientras conversás, registra anclas de lo importante — conceptos, mecanismos, procedimientos, errores frecuentes — con estado de dominio, y construye un mapa de estudio con tu punto de partida.

También podés subir PDFs y documentos, y activar búsqueda web con fuentes citadas. Tu perfil persiste entre sesiones. Spaces, la capa para organizar áreas, materias y sesiones, está en construcción.

Lunar es una herramienta de estudio gratuita para empezar, sin tarjeta de crédito: una alternativa real a un tutor para preparar exámenes, entender apuntes y repasar una sesión con sus anclas, mapa y fuentes.

Lunar

Not just another chat. Lunar picks where to start, checks what you understood as you go, and keeps track of where you stand on each concept — from one session to the next.

A chat answers and the conversation ends. Lunar answers, records what matters, and connects your questions — so a session leaves you with something you can use again.

Spaces

A clearer way to organize what you study

Spaces are containers for ongoing study: a broad area, subjects underneath, and sessions at the bottom. Every Space has its own knowledge tree, merging the one from all of its sessions, plus its own shared memory. Each session keeps its own tree; MicroChats do not become permanent nodes.

An area for each subject

The direction for Spaces is simple: a degree, course, or broad area on top; your subjects and sessions underneath.

Continuous context

We are building that organization so learning does not stay scattered across isolated conversations.

Spaces

One Space per subject, each with a tree that never resets

A Space is a broad area — a degree, a course, a project — that holds your subjects and, inside each one, the sessions you studied. It is not just a folder: every Space has its own knowledge tree and its own shared memory, so a new session starts knowing what you already covered in the others.

Each session keeps its own objective and topics; the Space keeps what ties them together. That is why the Space tree already has history when you open a new session.

MEMORY

Three layers, one source of truth

About you

How you like explanations, what you like, what you do.

Per Space

Purpose and what is shared across sessions.

Per session

Objective, topics, and progress in that session.

ROUTE MODE

A study route that moves with you

Hand it even your university syllabus and Lunar triages it: it keeps what is testable and prerequisite, marks the optional, and compacts what you already master. A visible plan of topics and subtopics that advances only when you truly understand — and you edit it by asking the AI, from the chat or with a pencil.

Knowledge tree

Lunar connects what you learned, session by session

Every session you finish feeds a graph: Lunar extracts the concepts, dedupes the ones it already knew, and links them with typed relations. Inside a Space the tree merges all of its sessions; inside a chat it covers that conversation.

WHAT THE TREE DOES

  • —It marks the current focus: where you are working in this session.
  • —It highlights mistakes in amber: the concepts people most often get wrong.
  • —It links each concept to the one that prepares it, so you see where it comes from.
  • —If the same concept showed up in two sessions, it becomes one node holding both paths.

HOW YOU OPEN IT

From a Space, the tree covers all of its sessions. From a chat, it covers only that session. Open a node and use "View in chat" to jump to where it was explained; the expand button opens it full screen.

Features

Everything in one place

A map that writes itself

While you study, the AI builds your continuity map: it picks the points worth keeping from 12 types (concept, formula, common mistake, decision…), organizes them as hierarchy or sequence depending on the case, marks where you are, and notes where you started. Not a summary: the visual memory of your learning.

Anchors: what is worth remembering

Reusable atomic units: concepts, mechanisms, examples, mistakes, and applications that get recorded and can be reviewed on their own.

Verifiable citations

Web search sources are cited and clickable.

MicroChats for deeper study

Open a side panel to ask focused questions about a concept without losing the thread of the main session.

Your documents, inside the session

Upload PDFs, documents, or text and use them as context to understand the topic better.

Free

Start without a credit card. No commitment.

How Lunar works

A session moves in three beats: ask, verify, and go deeper.

01
START

Open a session

Start with a question, a class, or a topic you need to understand.

02
CHECK

Advance with verification

Lunar revises what was already explained with short checks on material you have seen — without locking you into a level question. Upload documents when you need them: Lunar searches the web on its own when the question calls for it.

03
GO DEEPER

Go deeper on what matters

Review your Anchors and open a side MicroChat to explore a concept without losing the session.
