NullprintSet up your first profiles in 5 minutes
Install Nullprint on a Mac, sign up, add a US and a Japan proxy, create two profiles, run a check-up, then open Amazon in each: two separate browsers, each looking like a local visitor.
Quick start & video tutorials
Short videos that show how to use Nullprint, plus the same steps in writing. We add new tutorials here as they are published.
Getting started
The steps in writing
- Download and install — Download Nullprint from nullprint.ai for Windows or Mac (Apple silicon or Intel). On a Mac, drag Nullprint into Applications and open it from there.
- Sign up — Click Sign up, enter your email and a password, then type the 6-digit code we email you. New accounts start a free 7-day Team plan trial.
- Let the kernel download — The first time you sign in, Nullprint downloads its own Chrome kernel. It takes a minute or two and only happens once.
- Add proxies and check them — Open Proxies, click “+ Paste proxies”, paste one proxy per line (for example host:port:user:pass) and click Add. Then click “Check all”: green “Working” means the proxy is good.
- Create a profile — Open Profiles and click “+ New profile”. Give it a name you will recognize, like the store or account it is for. Leave Kernel and Chrome version as they are.
- Choose its proxy — On the Proxy tab, pick “From proxy pool” and choose a proxy. Time zone and language follow the proxy's location automatically. Click “Create & lock fingerprint”.
- Run a check-up — Select the profile and click Check-up. “Consistent” means the IP, time zone, language and fingerprint all agree.
- Launch — Click Launch. A separate browser opens with its own fingerprint, IP and cookies. Use it like normal Chrome.
AI automation (DeepSeek dsh)
One sentence to DeepSeek, and the browser shops Taobao by itself

One sentence, two countries: AI compares Amazon US vs Japan prices
With one sentence, the AI opens a US profile and a Japan profile at the same time, reads Amazon prices in each country and tells you where it is cheaper.
