Start with the essentials

The short answer

Most modern computers and phones already include AI-powered accessibility tools: a screen reader that reads text aloud and describes what is on screen, dictation that turns speech into typed text, live captioning that transcribes audio in real time, and image description that generates a spoken or written summary of a photo. These are usually built in and free, not separate purchases. The honest limit is accuracy: dictation mishears words, live captions lag and garble unfamiliar names, and image descriptions can miss or misstate what a photo actually shows. Used well, these tools remove a genuine barrier. Used uncritically, a wrong caption or a wrong image description can mislead exactly the person relying on it most.

What you will learn

  • You will be able to turn on and use your device's built-in screen reader well enough to navigate a simple page or document.
  • You will be able to use dictation to write text by speaking, and know the specific kinds of errors to check for afterward.
  • You will be able to turn on live captions for a video call or a video, and know what situations make captions less reliable.
  • You will be able to get an AI description of a photo and know what kind of detail it commonly gets wrong.
  • You will have a short checklist for when an AI accessibility feature's output needs a human check before you rely on it for something that matters.

Who it is for

Anyone who wants to use, or wants to help someone else use, the AI accessibility features already built into their computer or phone. No technical background needed.

Before you start

  • None. It helps to have read What is AI? if you are new to AI tools generally.

The complete workbook

This workbook is a practical tour of the AI accessibility features already built into most computers and phones: turning on and using a screen reader, dictating text instead of typing it, reading live captions on a video call or video, and getting an AI description of a photo when you cannot see it clearly yourself. Each section covers how to turn the feature on, what it does well, and a specific way it can get things wrong, so you know when to double check rather than take the output on trust.

  1. 01
    What is already built in, and why it is AI now

    Accessibility features used to be simple and rule-based. Most of the useful ones now use AI underneath, which is why they have become far more capable, and why they can also fail in AI-shaped ways.

    Screen readers: hearing a page instead of reading it

    Every major operating system has a screen reader built in, free, no extra software needed.

    Dictation: speaking instead of typing

    Dictation has gone from a niche, error-prone tool to something genuinely reliable for ordinary writing, with one recurring weak spot.

  4. 04
    Live captions: reading what you cannot hear

    Live captioning works well for clear, single-speaker audio and gets noticeably less reliable the further a real conversation drifts from that.

  5. 05
    Image description, and a before-you-trust-it checklist

    AI image description can turn a photo into a spoken or written summary, genuinely useful and worth knowing its specific blind spots.

Questions and answers

Do I need to buy anything to use these accessibility features?

No. Screen readers, dictation and live captions are built into Windows, macOS, iOS and Android at no extra cost. Some standalone image description apps exist, but the screen readers already built in also offer basic image description.

Is AI-generated live captioning accurate enough for a legal or medical record?

Treat it as a real-time aid for following along, not an official record. For anything with legal or medical consequences, a professional human transcript remains the reliable source, and captions should be checked rather than treated as final.

Why does dictation get names wrong so often?

Dictation predicts likely words based on how common they are in ordinary speech. An unusual name is, by definition, less common than the ordinary words it sounds similar to, so the system more often guesses the more common word instead.
