Get started with NotBot

System requirements, install, sign in, printer setup, and your first label.

Last updated Oct 12, 2026 · Applies to NotBot 1.4.4+

Setup takes about five minutes if your printer is already installed. This page covers what you need and the first-run flow; each part links to its step-by-step guide.

What you need

Section titled “What you need”
  • A Mac with macOS 12 (Monterey) or later, Intel or Apple Silicon, or a 64-bit Windows 10 or Windows 11 computer.
  • At least 8 GB of memory, and 16 GB on Windows if you can. On a Windows computer with 4 GB the show window can run out of memory during a long show and go blank. The processor matters less: NotBot prints just as reliably on budget laptops as on fast ones.
  • A MellowState account. Sign in with email and password, Google, or Apple, whichever you used to create the account. See Create your account.
  • A thermal label printer with the manufacturer’s own driver installed. Generic drivers (“Generic Text Printer”, “Generic / Text Only”) do not work with NotBot, on Mac or Windows. USB is the most reliable connection. See Recommended printers.
  • A way to go live on Whatnot, Poshmark Live, eBay Live, District, or TikTok Shop. Most sellers go live from a phone or tablet and run NotBot beside it on a computer.

1. Install NotBot

Section titled “1. Install NotBot”

Sign in on mellowtools.com and click NotBot in the menu on the left. The download buttons for Mac and Windows are on that page.

  • macOS: open the downloaded file and drag NotBot to Applications. Run it from Applications; a copy run from Downloads or the disk image cannot update itself.
  • Windows: run the installer. If Windows shows “Microsoft Defender SmartScreen prevented an unrecognized app from starting”, click More info, then Run anyway.

See Download and install NotBot.

2. Sign in

Section titled “2. Sign in”

Click Login to Continue. Your web browser opens the MellowState sign-in page, so you can use saved passwords and your Google or Apple sign-in. Once you approve, the browser hands you back to NotBot, which stays signed in across restarts. Your sign-in is kept in your computer’s secure credential storage.

See Sign in to NotBot.

3. The Getting Started window

Section titled “3. The Getting Started window”

The first time you sign in on a computer, a Getting Started window opens on top of NotBot and walks you through six screens:

  1. Welcome.
  2. Choose When to Print: Every Item, Buyer Only (chosen when you start) or Item + Buyer, with a moving example of each. See Print modes.
  3. Select Your Label Size: match the labels in your printer. See Label sizes.
  4. Connect Your Printer: pick your printer from Detected Printers (click Refresh if it is missing), set Feed Direction and Media / Roll if needed, and click Print Test Label.
  5. Using NotBot During a Live Show: a quick look at a typical show.
  6. You’re All Set!

I already know NotBot, skip setup on the first screen closes it, and Run Setup Wizard on the Settings drawer’s About tab opens it again. Every choice can be changed later in Settings. Set up NotBot with the Getting Started window shows every screen, and Connect and test your printer covers the printer in more depth.

4. Keep the computer awake

Section titled “4. Keep the computer awake”

If your computer sleeps during a show, NotBot loses the show and misses every sale until it wakes. Keep computer awake (on by default, in Customize › Advanced Settings › Show behavior) stops the computer and display from sleeping while a show is live. Closing a laptop lid can still sleep it, so keep the lid open and the laptop plugged in.

5. Go live

Section titled “5. Go live”

NotBot’s built-in browser opens Whatnot. For Poshmark Live, eBay Live, or District, go to that site in the built-in browser. For TikTok Shop, open your TikTok LIVE Manager there. Sign in to your seller account and open your show. Start the show the way you normally do, usually from your phone or tablet. To go live from inside NotBot instead, turn on Allow camera and microphone in Customize › Advanced Settings › Show behavior.

Make sure Auto-print (the switch at the top of the panel on the right) is on. As sales happen, NotBot prints labels for your print mode and shows everything in the live panel. In Buyer Only and Item + Buyer, it also gives each new buyer the next box number. After the show, everything is in Show History.

See Run your first show with NotBot.
