The problem

Asking ChatGPT means leaving the thing you’re doing.

You open a new tab, upload a screenshot, explain what you were trying to do, then switch back and figure out how to use the answer.

The usual way

Switch apps, explain everything.

Auto bitrate is making this export larger than it needs to be.

Lumini pointer

Auto bitrate is overshooting. Keep H.264, set bitrate lower, then export again.

Help without the detour

Lumini talks you through the thing you’re trying to understand.

Ask about a lesson, error, chart, setting, or question on your screen. Lumini answers out loud and can point to the part it means.

Siri

Great for device commands. Less useful when the problem is inside a spreadsheet, editor, form, or web app.

Google

You search, open a few tabs, skim long pages, then translate the advice back to the thing you were doing.

ChatGPT

Powerful in a separate chat. You still have to screenshot, explain the context, then carry the answer back.

Lumini

Ask about what’s on screen. Hear it explained.

Biology worksheetOn screen

Food chains: energy transfer

Look at the diagram. Explain where the energy starts and how it moves through the chain.

GrassRabbitFox

You ask

Why does the arrow start here?

The arrow shows where energy comes from. Grass is the producer because it makes energy from sunlight. Start there, then follow the arrows.

You do not have to explain everything

Ask about the lesson, error, chart, form, or setting already open on your screen.

You hear the next step

Lumini answers out loud so you can keep looking at the thing you are trying to finish.

The confusing part becomes obvious

When location matters, Lumini can point to the button, sentence, chart, or step it means.

You stay in control

For clicks, typing, or changes, Lumini shows what it will do and waits for approval.

The questions you normally take to Google.

Instead of opening tabs, reading around, and trying to apply generic advice, ask from the thing already in front of you.

What does this page mean?What changed in Nvidia earnings?Who won yesterday’s football game?Which of these plans should I choose?
What is this form asking for?Can you find the latest guidance for this?What should I reply to this email?What does this setting change?
Can you explain this homework question?What is this dashboard showing?What should I do next here?Can you quiz me on this topic?

Right where you are

Lumini works with the thing already open.

Lessons, homework, languages, tutorials, tools, dashboards, forms, code, and pages that do not explain themselves.

Learning, working, getting unstuck

When you get stuck, Lumini meets you there.

Use Lumini when the thing you need help with is already open and the next step is hard to explain in a search box.

Jordan

Frontend developer

Debug the scary red terminal

This worked yesterday. What broke, and what should I check first?

Stuck moment

A deploy fails after a small code change. The terminal shows a stack trace, but the real problem is buried in the middle.

What happens next

Lumini reads the visible error, points to the import path that changed, explains why the build cannot resolve it, and gives Jordan the first safe fix to try.

Sam

Maths student

Understand the step, not just the answer

How did they get from this line to the next one? Talk me through it slowly.

Stuck moment

Sam can see the worked solution, but one algebra line jumps ahead and the textbook explanation is too brief.

What happens next

Lumini explains the rule in plain English, points to the part of the line that changed, then gives Sam a similar step to solve out loud.

Riley

Operations manager

Turn a dashboard into an update

What should I tell the team about this spike?

Stuck moment

The support dashboard has tickets, backlog, and response time moving at once. Riley needs to explain what changed without overreacting.

What happens next

Lumini identifies the metric that moved most, explains the likely story, and helps Riley turn it into a short team update with the right caveat.

Taylor

Spanish speaking practice

Practise a sentence out loud

How would a native speaker say this, and can I practise it back?

Stuck moment

Taylor has a Spanish paragraph open, but the sentence sounds translated and she is not sure how a native speaker would say it.

What happens next

Lumini gives a natural version, explains the grammar difference, speaks it back, then listens while Taylor repeats it.

Privacy

It only listens when you ask.

Hold the shortcut to talk. Release it and the request ends. Lumini uses screen access to answer your question, not to watch your desktop.

Push-to-talk only

Lumini listens only while you hold Ctrl + Option. Release the keys and the request ends.

Screen access is request-only

Lumini uses your screen to answer the question you asked. It is not silently recording your desktop.

Actions need your OK

For bigger tasks, Lumini shows a plan first. It waits for approval before moving, typing, clicking, or continuing.

Your work is not the product

We do not sell your data or use your screen content and questions to train models.

Pricing

Try it on the things you get stuck on.
