Linewize Filter

A real-time content-aware filter designed for today’s online reality.
Helping you keep students safe, see what’s happening, and meet your duty of care with confidence.

An education filter that goes beyond searches, protecting students from what they actually see online.

Traditional filters focus on what students search. They block websites and turn activity into reports... which is the first step in keeping students safe and focused on learning.

But today, it’s what students encounter in the places that aren’t blocked that matters just as much.

Inappropriate content can appear halfway through a video, inside a shared document, or through an innocent search. And with new sites and AI-generated content being created constantly, it’s impossible to categorise everything before a student sees it.

That’s where Linewize Filter comes in.

Instead of relying on soley URL categorisation, it leverages AI to analyse content as it loads on the screen, providing real-time protection designed for how students actually use the internet.

Trusted by 1 in 5 schools across Aotearoa, we help create a safer, more predictable digital environment for learning.

Key benefits

Highest possible level of safety:

Real-time, content-aware protection

Analyses images, videos, and text (coming soon) as pages load, not just the website. Inappropriate or confronting content is filtered instantly, within platforms students use every day.

Protection beyond traditional website blocking

Looks inside pages, documents, and media where potentially harmful content can appear. Helps prevent inappropriate experiences that would otherwise slip through traditional filters.

Safety that keeps pace with the internet

Responds to new sites and AI-generated content as it appears. Content is assessed in real time, so students are protected even when material hasn’t yet been categorised.

Deputy Headmaster

The daily report about red flags is wonderful. If there are children searching for content that we believe is inappropriate and is a cause for concern, we can inform parents. Fantastic overall! I have been a leader in the IT curriculum and infrastructure projects for 15 years in both the UK and New Zealand, and this is the best solution I have worked with.

School Manager has changed the way that our kids use IT in the classroom. Previously, we had kids that were searching for anything and everything. The way that we did it was a friendly approach to let them know that we could see what they were doing but at the same time just educating them on how to use the technology well.

Principal

School Manager has led to a really interesting conversation with those children around what they were doing and why, and do you think that’s appropriate. Ironically, there have been no more red flags with those children.
