For dyslexia, the most useful AI tools on a phone do four things: read text aloud, turn dense writing into plain language, catch spelling and grammar in your drafts, and help you plan what to write before you start. Your phone already has free read-aloud tools built in, and an AI chat app adds the simplifying, checking and planning. If the text is personal, like a medical letter or a work email, you can do all of it with an AI that runs on the phone so nothing is uploaded.
The British Dyslexia Association describes dyslexia as “a specific learning difficulty which primarily affects reading and writing skills,” though it affects how information is processed more broadly. None of these tools diagnose or treat it. They’re practical supports, alongside whatever help works for you at school or work.
Which phone tools help with dyslexia? #
| Need | Built-in phone tool | What AI adds |
|---|---|---|
| Hear text instead of reading it | Speak Screen (iPhone), Select to Speak (Android) | Read-aloud of AI answers and summaries |
| Understand long or complex text | None built in | Summaries and plain-language rewrites |
| Read text on paper or signs | Camera text reading in Select to Speak | Ask questions about a photo of the page |
| Spell and write | Keyboard autocorrect, spell check | Fix a whole draft and explain the changes |
| Organize thoughts before writing | None | Turn rough notes into an outline |
Free read-aloud tools already on your phone #
iPhone: Speak Screen and Speak Selection #
- Open Settings > Accessibility > Spoken Content.
- Turn on Speak Selection to get a Speak button whenever you select text.
- Turn on Speak Screen, then swipe down from the top of the screen with two fingers to hear the whole page read.
- Turn on Highlight Content so words are highlighted as they’re read, which many people find easier to follow.
Android: Select to Speak #
Google’s Select to Speak reads items on the screen aloud when you tap them or drag across them. Turn it on in Settings > Accessibility > Select to Speak. It can also use the camera: point it at printed text or a picture to hear it read or described, in 17 supported languages. It needs Android 11 or later.
How AI helps with reading #
Read-aloud handles decoding the words. AI helps with the next problem: long, dense writing that’s tiring to get through even when you can hear it.
- “Summarize this in five short bullet points.” Good for long emails, articles and letters.
- “Rewrite this in plain English, short sentences, no jargon.” Good for forms, policies, contracts and school reading.
- “What do I need to do, and by when?” Pulls the actions and dates out of an official letter.
- “Explain this word” for any term you’re unsure of, in context.
- Take a photo of a page and ask what it says or means, for handouts, menus, notices and forms.
For long documents, see explain a document in plain English.
How AI helps with writing #
Many people with dyslexia know exactly what they want to say and find the spelling, structure and proofreading the hard part.
- Brain-dump first. Type your thoughts in any order, with any spelling. Ask: “Turn these notes into an outline with headings.”
- Draft from the outline, one section at a time.
- Check it. “Fix spelling and grammar. Keep my wording. List what you changed.” Asking for the list helps you learn your common slips.
- Hear it back. Have the result read aloud; errors often jump out when you listen.
- Adjust the tone for the reader, from a teacher or manager to a friend.

Doing it privately, on the phone #
A lot of what people need help reading is personal: medical letters, bank statements, school reports, HR emails, legal forms. Pasting those into a cloud chatbot sends them to the company that runs it.
Personal LLM runs open models such as Qwen 3.5 and Gemma 4 on your phone, so the text never leaves it. Features that help here:
- Read aloud: on-device text-to-speech for any answer, with no voice service involved.
- Documents: attach a PDF, text or Markdown file and ask questions. The app searches it on the phone and answers from the matching passages, showing which ones it used.
- Photos: ask about a photo of a letter, form or page once you’ve added image support for a model.
- Copying: copy a whole answer or just the sentence you need.
- Per-chat instructions: set a system prompt like “Always use short sentences and simple words,” so every answer in that chat comes out easy to read.
Two honest limits. First, Personal LLM doesn’t take voice input, so you type your questions; your keyboard’s own dictation button may work, but on some phones keyboard dictation sends audio to Apple or Google, which our guide to offline speech-to-text on iPhone explains. Second, a phone-sized model can misread or oversimplify, so for anything important, like medication instructions or a legal deadline, check the key facts against the original or ask someone you trust.
Tips that make AI answers easier to read #
- Ask for short paragraphs, bullet points and one idea per line.
- Ask it to avoid jargon, or to explain any hard word in brackets.
- Ask for the answer first, then the detail.
- Use your phone’s display settings, like larger text, bold text and dark mode, which carry into most apps.
- Keep one chat per topic, so the conversation stays short and easy to scroll.

Frequently asked questions #
What is the best AI tool for dyslexia? #
A combination works best: your phone’s built-in read-aloud (Speak Screen on iPhone, Select to Speak on Android), plus an AI chat app to summarize, simplify and proofread. Choose an on-device app if you’ll be working with personal documents.
Can AI read text aloud from a photo? #
Android’s Select to Speak can read printed text through the camera. AI chat apps with image support can also describe or explain a photo of a page, and then read the answer aloud.
Is it cheating to use AI for dyslexia? #
Using AI to read, spell-check and organize your own ideas is support, much like a spell checker or text-to-speech. At school or university, check the rules for each assignment, since some tasks limit AI use, and tell your teacher what tools you use if you have a support plan.
Can AI help with spelling for dyslexia? #
Yes. You can paste a draft and ask the AI to fix spelling and grammar while keeping your words, and to list the changes so you can see patterns. Hearing the corrected text read aloud is a good final check.
Is it safe to use AI with private letters and documents? #
With cloud chatbots, the text goes to the company’s servers. With an AI app that runs on your phone, nothing is uploaded, which makes it a better fit for medical, financial and school documents.
