AI Vision Apps for Blind Users

How smartphone apps using artificial intelligence describe the world to blind people, their economics, and what they cannot yet do.

For decades, tools that read printed text or identified objects for blind people were expensive, specialised devices. Smartphone apps powered by artificial intelligence have changed that economics dramatically.

What the apps do

AI vision apps use a phone’s camera to:

Read printed and handwritten text aloud.
Describe scenes, objects and people.
Identify banknotes, colours and products.
Describe images on screens and in documents.

Microsoft released Seeing AI in 2017, offering many of these features for free. Be My Eyes, launched in 2015, originally connected blind users with sighted volunteers through video calls. In 2023 it added Be My AI, a feature that uses a large AI model to describe photos in detail and answer follow-up questions.

The economics

These apps have shifted costs dramatically:

Free or low cost: many are free to users, funded by technology companies, which use them partly to demonstrate their AI and build goodwill, or by business partnerships.
Mainstream hardware: they run on ordinary smartphones rather than specialised devices costing thousands of dollars.
Scale: because they serve a global market, development costs are spread across many users.

This follows a broader pattern in assistive technology: when accessibility features are built into mainstream products, costs fall sharply.

Reading the post

A blind person receives a letter. In the past, they might have needed a sighted person to read it, or a dedicated reading machine. Now they photograph it with a phone app, which reads it aloud in seconds. They can then ask the AI follow-up questions, such as the due date of a bill. The cost is close to zero, and privacy and independence are greatly improved.

Limits and risks

AI descriptions can be wrong, sometimes confidently so, which matters for things like medication labels. Apps depend on internet access and on companies continuing to fund them. Privacy concerns arise when personal images are processed in the cloud. Many users combine AI tools with human help for important tasks.

Thinking AI apps have solved accessibility

AI apps are powerful, but they do not replace accessible design. Websites, documents and products still need to be built accessibly, and AI can make mistakes. They are a valuable tool, not a complete solution.

Key takeaways

AI vision apps read text, describe scenes and identify objects for blind users.
Seeing AI and Be My Eyes brought these capabilities to smartphones, often for free.
Building accessibility into mainstream devices sharply lowers costs.
AI can make errors and raises privacy concerns, so it complements rather than replaces accessible design.
