Nox now repeats routines for almost nothing

nox.cool can now repeat a routine's browser steps without the main AI. In our test, a run that cost about 11¢ cost 0.03¢, and took 5 seconds in place of about 20. You can also mark up PDFs and Word files, and ask for a page that follows your Stripe payments.

A routine called Check in for Friday, with the line: The last 2 runs took the same 3 steps. Repeat them without the AI, for almost nothing. It won't choose anything new.

Key points

  • A routine that takes the same browser steps each time can repeat them without the main AI. In our test, about 11¢ a run became 0.03¢.
  • It's off until you turn it on. If a step has gone, the AI takes over from there, and anything that needs your OK still asks.
  • Select words in a PDF, Word file or deck, or draw a box on a PDF's page, and your note goes to the agent with exactly that marked.
  • Ask for a page that follows your Stripe payments. Each payment lands with no AI run, so it costs nothing per payment.
  • Ask for a small tool like a timer, and it stays beside the chat until you close it.
  • Tell Nox something is decided, OK it on a card, and every agent keeps to it until you reopen it.

nox.cool can now repeat a routine's browser steps without the main AI. In our test, a run that cost about 11¢ cost 0.03¢, and took 5 seconds in place of about 20. In the same update, you can mark up PDFs and Word files, and ask for a page that follows your Stripe payments.

How do I make a routine cost almost nothing?

Open Routines. Once a routine has taken the same browser steps twice, a line appears under it. Click Repeat them without the AI. You can also just ask Nox: "repeat my check-in routine without the AI".

A routine called Check in for Friday, with the line: The last 2 runs took the same 3 steps. Repeat them without the AI, for almost nothing. It won't choose anything new.
The offer appears once the AI has done the job the same way twice. It stays off until you click.

It's off until you turn it on, because an AI run chooses what to click and a repeat doesn't. If a step has gone, the AI takes over from there. A button that spends money or speaks for you still stops for your OK. Runs that used email, saved logins, connected apps or files can't be repeated this way.

One test routineWith the AIRepeated
Cost per run13.2¢ and 10.7¢0.03¢
Time per run26 s and 18 sabout 5 s

That routine opens a page, clicks a link and reports the heading it finds. Your own routines will cost more or less, depending on what they do.

How do I point at what's wrong in a document?

Open Documents, or click a file in a chat. Select the words you mean and click Comment. On a PDF, you can also click Mark a part and draw a box. Say what should change, then click Send.

In our test on a Word file, Nox came back with a new copy, "thirty" struck through and "sixty" tracked, and nothing else changed.

How do I get a page that follows my Stripe payments?

Ask: "Make me a page that shows my Stripe revenue as it comes in." Approve the card. Then open Sites, copy the address into Stripe's webhooks, and paste Stripe's signing secret back. Nox never sees the secret.

Each payment goes straight onto the page with no AI run. If the figures are private, open the page with Open it with your private data on your Sites page. Everyone else sees nothing.

How do I keep a small tool on my screen?

Ask: "Make me a countdown timer I can keep on my screen." It sits beside the chat on every page until you close it. Drag it by its title, or make it small and it keeps running. It's sealed off, so it can't reach your accounts.

What else is new?

  • Settled decisions. Say "we've decided on Stripe, that's final". You OK it on a card, and every agent keeps to it until you reopen it.
  • Topics. Say "start a topic for my trip" to keep it apart, with the same agent, computer and memory.
  • Word and Excel lose less. Nox now reads nested tables, text boxes and every header and footer, and tracked changes reach headers and footers too.
  • Files up to 200 MB, and a clean copy to send outside, with author names and comments removed.
  • Arabic and Hebrew messages now flow the right way on any screen.
  • "What should I automate?" Nox reads two weeks of your work, when you ask, and picks three things.
  • A short note after each update, once, with a button to try each new thing.

Questions and answers

How do I repeat a routine without the AI on nox.cool?

Open Routines. Once a routine has taken the same browser steps twice, a line under it offers to repeat them. Click Repeat them without the AI, or ask Nox to do it. Click Think it through each run instead to go back.

What happens if a website changes and a step isn't there?

The AI takes over from that step. It sees everything done so far and finishes the job. That run costs about what an ordinary run costs, and the steps it took become the ones repeated next time.

Can a repeat buy something or send something without asking me?

No. Each repeated step goes through the same checks as a step the AI takes. A button that spends money or speaks for you stops for your OK, and your own rules still apply.

Does a repeat use any AI at all?

A little, at the end. A small AI model reads the last page to write your one-line result and to check the job went as it should. That's what the 0.03¢ pays for.

Which routines can't be repeated?

Runs that used anything beyond the browser: email, saved logins, connected apps, files or the computer's desktop. Those keep running with the AI as before. It also isn't for a job that needs choosing, because a repeat clicks what was clicked last time.

Which documents can I comment on?

PDFs, Word files, PowerPoint decks and plain text files. A PDF shows as its real pages. Word files and decks show as their words, so to draw a box on a page you need a PDF.

Where can I try it?

It's part of nox.cool's early access, which is by invite for now.
