A real screenshot. NONON has just compared two spreadsheets and lists every row that does not match.
Meet NONON
NONON is a helper for the files you already have. Say what you need in your own words. It does the work on your computer, shows you the result, and asks before it changes anything.
The AI runs on your computer. Your files stay in your folders.
Like you would to a coworker. You do not need to learn how to write prompts.
Before it changes a file, it saves a copy of the original.
What it does
Give it your files and say what you need. Here is what it can do today.
And also
Job 1 of 3
Give it two Excel or .csv spreadsheets, like your bank list and your own records. It shows every row that does not match. It adds up the money itself, so the totals are exact.
From a real comparison of two test files, 51 rows in all
The two totals differ by 2,565.60 PHP. Code added it up, so it is exact.
Job 2 of 3
Give it your notes. You get a short summary and a list of who does what. Anything missing, like a name or a date, is marked for you.
Job 3 of 3
Give it a reading. You get a study sheet with practice questions and an answer key. It is built only from your reading.
And also
NONON lists every move first. Nothing moves until you say OK.
And also
Get a first draft from your notes or a file. Then edit it your way.
And also
Repeat a job every week. It runs while your computer is on and awake.

Your control
NONON is a helper, not the boss. It asks before it changes anything.
NONON shows what it wants to change and waits for your OK.
Before it changes a file, it saves a copy of the original.
Changed your mind? Undo it. If you edited the file since, NONON stops and tells you. It will not erase your work.
Try it A demonstration. Nothing on your computer is touched.
Non wants to move 3 filesinto a new folder called Invoices 2026
Waiting for your OK. Nothing has moved yet.
Nothing changed. The 3 files stay exactly where they were.
Done. A copy of each original was saved first, so you can go back.
Undone. The files are back where they were.
Where it runs
Your files, backups and routines stay in your folders. Try the switch to see what keeps working with no internet.
Needs the internet once to download the AI (3 to 6 GB). After that, its core jobs work offline. Gmail and online AI always need the internet. Some parts are still being tested, so please read what works today.
This is how NONON starts.
Off until you switch it on. NONON tells you what will be sent first.
How it works
Three steps. You do not need to learn how to write prompts.
Choose the folder with your files. NONON only works where you point it.

Not by default. Your files and the AI stay on your computer, and this site has no tracking. Setup downloads the AI from public websites. If you turn on Claude, Codex, Antigravity or Gmail, the content of that job goes to that service. NONON tells you before it does. Read the privacy page for the full list.

By default, a small open AI that runs on your computer. You can also connect Claude, Codex or Antigravity if you already use them. They are optional.
A small AI can make mistakes. So NONON adds up the numbers with ordinary code, shows where each result came from, and marks what is missing. It never changes your files until you say OK. Check its work the way you would check a new helper's.
Yes. NONON saves a copy of the original before it changes a file, and you can undo from there. If you edited the file after that, NONON stops and tells you instead of writing over your work.
