CLEAR

Free to use. No sign-in needed.

Understand anything.

Ask a difficult question. CLEAR turns the answer into one checked explanation, then shows it as a summary, a mental model, a diagram, worked examples and a quiz, so you know it actually clicked.

Ask a question

CLEAR Free runs on Gemini. Or bring your own API key.

Or start from a question people ask

The preview shows one lesson about virtual memory as six views: a one-sentence explanation, an analogy, a diagram, a step-through, a quiz and a teach-it-back check.

How it works

From a question to real understanding.

  1. 01

    Ask your way

    Type a question, speak it, or attach an image or a PDF. Choose your level and how deep to go.

  2. 02

    CLEAR builds one explanation

    A single checked document: concepts, relationships, a mental model, examples and a quiz. Every view is drawn from it.

  3. 03

    Learn until it clicks

    Switch views, ask follow-ups that update the same lesson, then quiz yourself or teach it back.

Ten views of one explanation

One document, explained ten ways.

CLEAR writes one checked explanation document, and every view reads from it, so the diagram, the analogy and the quiz never disagree. Choose a view to see what it reads.

Understand reads essence, whyItMatters, prerequisites, concepts, process and terminology.

Your level

The same idea, at your level.

Pick a level and the words change. The truth does not. Then answer one question, the way every lesson ends.

How does public-key encryption work?

You publish one key and keep the other secret. A message locked with your public key can only be opened with your private key, so a stranger can write to you safely without the two of you ever sharing a secret.

A stranger has your public key. What can they do with it?

Pick an answer. CLEAR ends every lesson with questions like this one.

These four samples are written by hand. Your lesson is generated for your own question.

Model independent and private

Any model. Your keys. Your data.

The model is an implementation detail. The way CLEAR teaches stays the same, and your lessons stay yours.

  • CLEAR Free runs on Google Gemini. No sign-in, no key.
  • No silent switching between providers. The lesson always names the model that answered.
  • Run the same question on two models and keep the clearer explanation.

Private by default

  • API keys are encrypted at rest and are never sent back to your browser.
  • A guest lesson belongs to the browser that created it. Nobody else can open its address.
  • Uploaded images and PDFs stay private. They never get a public link.
  • Learning memory is off until you turn it on, and you can delete it.
  • Sharing publishes a frozen snapshot that you preview first. You can replace or revoke the link.
