Everything people ask before installing it
If your question is not here, email support@sureno.ai and it probably will be.
Is Sureno built on Chrome?
It is built on Chromium, the open-source engine underneath Chrome and Edge. Pages look and work the same, in the same sandbox, with the same site isolation. Sureno is an independent browser from sureno.ai, not a Chrome extension, theme or modified copy of Chrome.
Is there a Windows version?
It is on its way. Sureno runs on Mac today, and the Windows version is being prepared now. Join the Windows list and we will email you the day it is ready.
Who writes the explainers on sureno.ai?
They are written with the help of AI from numbered, linked sources, then checked automatically for accuracy against those sources, for copying and for clickbait before anything is published. Health and money pages never give advice. Here is exactly how it works.
Are the free tools really private?
Yes. The PDF, image and text tools run inside your own browser. Your files are never uploaded to us or anyone else, which is also why they are fast.
Do I lose my bookmarks and passwords if I switch?
No. The first-run import copies your bookmarks, history and open tabs. Your old browser keeps everything exactly as it was, so you can use both for a week and decide calmly.
What does the assistant do with the page I am reading?
Nothing, until you ask it something. There is no background summarising and no page text uploaded while you browse. See the privacy page for the specifics.
What does it cost?
Sureno is free, and there is no trial that expires. An account is optional. Sign in to keep saved stories, reading history and points. You can read everything without one.
Which platforms is Sureno available on?
macOS 12 or later on Apple silicon, today. Intel Macs, Windows and Linux are on the roadmap, and there is no mobile app.
Why does macOS warn me when I open it?
Because the build is not yet notarised by Apple. Right-click the app and choose Open the first time. That warning exists for good reason — only install Sureno from a link on sureno.ai, and check the checksum on the security page when one is published.
Can I change the search engine?
Yes, in Settings. Google is the default because it is what most people expect from the omnibox.
Is my data synced anywhere?
No. Everything is on your Mac. Sync does not exist yet, which is a genuine downside as well as a privacy property.
Do you use my browsing to train anything?
No. We do not receive your browsing, so there is nothing to train on. Questions you send to a third-party model provider are subject to that provider's terms — which is one reason the local model option exists.
Is Sureno open source?
The engine underneath is: Chromium and Electron. The Sureno application itself is not published today. If it becomes so, it will appear on the roadmap first.
How do I set it as my default browser?
System Settings → Desktop & Dock → Default web browser. Sureno also offers once on first launch, and does not ask again if you decline.
What happens to my tabs if it crashes?
They come back on the next launch, along with any projects, which is the main thing projects are for.
Try a calmer browser for a week
Sureno copies your bookmarks and passwords rather than moving them, so your old browser stays exactly as you left it. If Sureno is not for you, uninstalling takes under a minute.
