How it works

Set it up once. Then forget it.

Three things happen the day you install it. After that it is one keypress, forever.

1
Install it
One installer, a few clicks, and it sets up your AI for you. No keys to paste, nothing technical.
2
Open your practice quiz
A practice test, a past paper, a homework sheet — any site, any browser, any app. OneTapAnswer waits in the corner of your taskbar.
3
Press two keys
Ctrl and Enter. The answer — and why, if you want it — arrives as a small notification, the way a message does. Nothing covers your work.

What you get

Everything you need. Nothing you have to learn.

One hotkey. One notification. Every clever part happens where you cannot see it.

Works on any quiz, anywhere

It is not a browser add-on. It reads whatever window is in front of you — a quiz site, a practice test, a PDF of past papers, a study app.

Works with the internet off

A train, a plane, a dropped connection. Set the offline AI up once and it answers from your own computer instead.

It tells you why

Switch to Detailed and the answer comes with its reasoning — why it is right, and why each other option is not. That is the part that makes practice stick.

Every kind of question

Multiple choice, tick-all-that-apply, true or false, fill in the blank, matching. It works out the format and answers in it.

Answers as short as you like

Just the letter when you are checking a whole sheet. A line of reasoning, or all of it, when you want to learn it. Switch whenever.

A spare AI, one keypress away

Two AI providers set up side by side. If one is busy or slow, Ctrl+M moves to the other without leaving your quiz.

Your call

A letter, or the whole explanation.

Four styles of answer, changed from the tray in one click. Take just the letter when the clock is running, or the full reasoning — including why the other options are wrong — when you want to actually understand it.

See the four styles

Letter onlyThe default. Fastest to read.
OTA: B
ChoiceThe letter and what it says.

Short explanationOne line of reasoning.
OTA: B — the cell's powerhouse.
DetailedTap it for the full reasoning. On a Mac or Linux: Show explanation in OTA's menu.
OTA: B) Mitochondria (tap for details)

Every format

It answers the way your quiz asks

Letters, numbers, roman numerals, tick boxes, blanks, matching pairs. It works out which one it is looking at and replies in the same shape — you never tell it anything.

Don’t take our word for it.

We built a practice quiz with every one of these question types on it. Install OTA, open the quiz, and spend one of your free answers proving it works — on something that does not matter.

The brains

Pick an AI. Or don’t.

Four of the best are built in and set up for you during install. If you have no opinion, the recommended one is already ticked.

Recommended

ChatGPT

The one most people should pick. Set up for you during install, signed in with one click, and works on a free ChatGPT account.

Best answers

Claude

Stronger on long, wordy, tricky questions. Needs a paid Claude plan (Pro or above); connecting is one click. Have both and swap between them.

Also free

Gemini

Google's, signed in with the account you already have. It takes longer to answer than the other two, so it is the one to reach for when the other two are busy.

No internet needed

Answer Offline

An AI that runs on your own machine instead of the internet. It answers when the network is down or simply not there — no account, no cost, and no question ever leaves the room.

No API keys. No subscriptions to anybody else. No command line — ever.

No connection needed

The Wi-Fi can go. Your answers don’t.

One of the four AIs runs on your own computer rather than on somebody’s servers. Set it up once, and when the network is down or simply not there, OTA turns to it by itself — same keys, same notification, no setting to change.

Patchy Wi-Fi and dropped connections
Aeroplanes, trains and dead spots
Back to your usual AI the moment it returns
Nothing leaves the machine — ever

How to set it up →

Your screen stays yours

One window. Nothing kept.

It reads the window you are looking at and not one pixel more — not your other apps, not your second screen, not your taskbar. What it reads is held in memory for the few seconds it takes to answer, and then it is gone. Nothing is saved, and nothing about your questions ever reaches us.

Only the window in front of you
Held in memory, never saved
No history of what you asked
An offline mode that sends nothing at all

The things people ask first

Do I need to be good with computers?

No. If you can install an app, you can use this. The installer does every technical part for you behind a progress bar — you never see a command line, and there is nothing to configure afterwards.

Will it work on the quiz site I use?

Yes. It does not need to know your quiz site. It reads whatever window is in front of you, the same way you do, so the site, the browser and even whether it is a website at all make no difference.

Does it explain the answer?

Yes, when you want it to. Short explanation adds one line of reasoning to the notification. Detailed opens the full working, with why each of the other options is wrong.

What does it cost to try?

Nothing, and it stays that way. Every account gets 10 answers a month free, resetting on the 1st, with no card asked for at any point. A plan only makes sense once you are using more than that.

Can I use it on my laptop and my desktop?

Yes — two computers on every plan, including the free one, in any mix of Windows, Mac and Linux.

What happens if the internet drops?

It keeps answering. Set the offline AI up once — it lives on your own computer — and OTA turns to it the moment the connection is gone, without you pressing anything, then goes back to your usual AI on its own when the connection returns.

Do my questions get stored anywhere?

No. What it reads is held in memory, sent to the AI you chose, and thrown away. Nothing is written to a file and nothing is kept on our servers.

Anything else is probably in the full FAQ.
