Assistive technology from Biosilico

It meets you where you are. Reading, writing and focus support that works the way you do.

Zonedin is assistive technology for anyone the screen has stopped working for - through dyslexia, low vision, visual stress, colour vision difference, ADHD, fatigue or a language barrier. Text-to-speech, dictation, reading aids, calmer colours and visual access, set up the way you take information in. Choose the browser, the whole-computer toolbar, or both.

Reading and writing shouldn't be this hard.

Screens are built for an imagined average user - someone who sees the small print, takes in a page at a glance, types without effort, and isn't thrown by glare, clutter or noise.

For millions of people - with sight loss, dyslexia, colour-vision differences, visual stress, attention differences, fatigue, or a language barrier - that's not how it feels. Every document, every page, every form is a small negotiation: zoom in, squint, fight the colours, lose your place, reach for yet another separate tool, start again. Getting the information in and the words back out takes more energy than the work itself.

Zonedin starts from the other end. You set things up the way you take information in - once - and the support is there whenever you need it, whether you're on the web or deep in a document.

One idea, two products.

Both put you in control of how you read, write and focus. The difference is where they work - the web with the Browser, and every other application with the Toolbar.

Zonedin Browser

A complete web browser built for super-focus. It strips ads, trackers and clutter from every page, then hands you the words, colours, pace and voice controls - working on every website, including the ones that block extensions.

Best when most of the reading and work happens on the web.

Zonedin Toolbar

An assistive technology toolbar for Windows. Text-to-speech, dictation, writing support, study skills and visual access that follow you across Microsoft Word, email, PDFs, virtual learning environments and workplace systems.

Best when support is needed in desktop programs outside the browser.

Made for the way you read.

We built Zonedin because the modern screen has forgotten a lot of people. If text is too small, if colours sting your eyes, if the page won't sit still, if your eyes lose their place, if a busy layout makes it hard to focus - none of that is your fault.

Zonedin gives you the tools to set things right, whether you're on the web or deep in a Word document. Your settings stay on your own computer. There's no account to create, no sign-in, nothing to remember.

For professionals

Are you an Access to Work or DSA assessor?

Zonedin is designed so that one recommendation can cover several access requirements at once - across visual impairment, dyslexia, colour vision, attention, motor difficulties and chronic fatigue.

A separate assessor brief sets out the needs mapping, the licensing terms, and a paragraph you can lift straight into your report.
