NEW The AI agent at the tip of your cursor

Your cursor just
got a brain.

Hold one key and ask anything. Praxis sees your screen, talks back, and draws the answer live: math and diagrams on a live board, code explained in place, and step-by-step guides through any app.

Explains on the board

Math, physics and machine learning, drawn step by step while it explains.

Praxis on a real screen: Derives the Transformer attention formula, step by step — **Derives the Transformer attention formula, step by step**“Can you derive the formula of attention step by step on your board?”

Praxis on a real screen: Draws a neural network and sends a signal through it — **Draws a neural network and sends a signal through it**“Draw a neural network and explain the backpropagation equation on the Praxis board.”

Praxis on a real screen: Then writes the backpropagation chain rule on top — **Then writes the backpropagation chain rule on top**“Draw a neural network and explain the backpropagation equation on the Praxis board.”

Praxis on a real screen: Maps the Bloch sphere in 3D — **Maps the Bloch sphere in 3D**“Can you show me how the Bloch sphere is mapped by drawing it?”

Circle anything, ask anything

Draw around what confuses you and ask “what’s this?”

Praxis on a real screen: Explains the chain rule you circled on Wikipedia — **Explains the chain rule you circled on Wikipedia**“What is this that I marked on the screen? Explain it.”

Praxis on a real screen: Works through the integral you circled in your homework — **Works through the integral you circled in your homework**“What is this that I marked on the screen? Explain it.”

Understands your code

Circles, underlines and annotates code right in your editor.

Praxis on a real screen: Explains the function you circled — **Explains the function you circled**“What is this that I marked on the screen? Explain it.”

Praxis on a real screen: Explains list indexing, line by line — **Explains list indexing, line by line**“Can you explain the list in this code?”

Explains diagrams piece by piece

System design, architecture and flowcharts, one component at a time.

Praxis on a real screen: Walks through a system design diagram… — **Walks through a system design diagram…**“Can you explain this diagram by drawing on your board?”

Praxis on a real screen: …one component at a time — **…one component at a time**“Can you explain this diagram by drawing on your board?”

Charts, games and everything else

If it's on your screen, Praxis can point at it and explain it.

Praxis on a real screen: Circles where you'd profit and where you'd lose — **Circles where you'd profit and where you'd lose**“Can you tell me where I will make a loss and where I will make a profit?”

Praxis on a real screen: Then explains entry price, profit and loss on the board — **Then explains entry price, profit and loss on the board**“Can you tell me where I will make a loss and where I will make a profit?”

Praxis on a real screen: Marks a move in a live chess game — **Marks a move in a live chess game**“Can you mark on the board which piece to move?”

What it can do

An agent that shows, not just tells

Everything happens right on your screen, in the app you're already using.

Hold a key. Ask out loud.

Hold Right Ctrl, ask your question, let go. Praxis looks at your screen and answers by voice, with live captions. Prefer typing? Ask from the tray instead.

Points at the exact button

Its buddy cursor flies to exactly what you need. It reads the real buttons on screen, so it isn't guessing.

Draws while it explains

Circles, arrows, spotlights and handwritten notes, drawn stroke by stroke and timed to every sentence.

Explains on a live board

For math, code and concepts, a board slides in and the diagram builds up step by step as it talks.

Exact geometry

Squares are truly square and angles truly right. It even snaps to the corners of a triangle already on your screen.

Real diagrams, not scribbles

Spheres, cubes, cylinders and cones in 3D. Neural networks with a signal pulsing through them. Graphs of any function, and flowcharts. Praxis computes each one exactly, then draws it by hand.

sphere · cube · cone · neural network · y = f(x) · flowchart

Circle to ask

While holding the key, draw around anything with your mouse and ask "what's this?"

Guides you click by click

"How do I export a PDF?" It points at step one, waits for your click, looks again, then shows the next step until you're done.

Speaks your language

Multilingual: ask in English, Hindi, Bangla and more, and hear the answer spoken back in your language.

Speaks math and code naturally

You hear "a squared plus b squared equals c squared", never a jumble of symbols. The formula still appears on the board.

A buddy with personality

Its eyes follow what it's doing. It blinks, lip-syncs to its own voice, and smiles when it's done.

Only looks when you ask

Praxis sees your screen only while you hold the key. Nothing is saved on your PC, and it barely uses your CPU when idle.

The board

From a formula to a picture in seconds

Ask about a concept and Praxis draws it: exact, colorful, and built up while it explains.

Sphere · V = 4⁄3 πr³

Neural network · live pulse

Any function, plotted exactly

Flowcharts & processes

How it works

Three seconds from question to "oh, I get it"

Hold `Right Ctrl`

From any app: your browser, Excel, a PDF, your homework. The buddy starts listening.

Ask, or circle it

Say your question out loud, or drag around something with your mouse and ask "what's this?"

Watch it explain

It talks you through the answer while pointing and drawing on your screen, one step at a time.

Made for

Built for students.
Ready for anyone on a screen.

Made for you first

🎓 Students

Stuck on a formula, a proof or a line of code at 2 a.m.? Hold one key and Praxis explains it right on your screen: on your notes, your slides, your assignment. It draws the diagram, walks through each step, and answers follow-up questions in your language.

"Why is c² = a² + b²?"

"Explain this integral I circled."

"How does backpropagation work?"

💻 Developers & coders

"What does this function do?"

Circle code in your editor and get it explained in place, with system and architecture diagrams broken down piece by piece.

📊 Analysts

"What's happening in this chart?"

Point at a spike, a trend or a formula in your sheet or dashboard, and Praxis circles it and explains what it means.

🧭 Learning new software

"How do I make a pivot table?"

Guided mode walks you through Excel, Canva, Photoshop and more, one click at a time, pointing at the exact button.

FAQ

Questions

What computers does Praxis work on?

Windows 10 and Windows 11. A microphone helps, but you can also type your questions.

Does it watch my screen all the time?

No. Praxis only looks at your screen while you're holding the key to ask a question. Nothing is saved on your computer.

Which languages does it speak?

English, Bangla and Hindi today. It answers in the language you ask in, and understands many more.

Can it click things for me?

Praxis guides you rather than taking over. In guided mode it points at each step and waits for you to click, so you actually learn how to do it.

Is there a Mac version?

Not yet. Praxis is built for Windows first. Join the waitlist and tell us if you'd like other platforms.

When can I try it?

We're inviting people from the waitlist in small batches. Sign up and we'll email you when it's your turn.
