Grammarly, SwiftKey, and others can read everything you type — your passwords, your banking details, every message in every app. ChatMinder’s built-in writing assistant only ever sees one thing: the message you’re writing right now.
If your child struggles with writing — whether from dyslexia, SEND, autism, or just the general chaos of typing quickly on a phone — you’ve probably looked at keyboard apps that promise to help.
Grammarly Keyboard. SwiftKey. GBoard. They can fix grammar, rephrase sentences, adjust tone. For many adults, they’re genuinely useful.
But there’s a catch. And if you have a child, it’s worth understanding before you install one.
The problem with third-party keyboard apps
To give an AI-powered keyboard app access to the words you’re typing, iOS and Android require something called Full Access.
iOS makes this unusually transparent. When you enable full access for a third-party keyboard, the system shows a warning that reads: “This could include sensitive information such as your credit card number or street address.”
That warning isn’t hyperbole. A keyboard app with full access can, in principle, log everything typed on that device — across every app. Banking passwords. PINs. WhatsApp messages. Emails. Every search term. Every address. Everything.
Security researchers have flagged this concern repeatedly. In 2023, several popular keyboard apps were found to be transmitting keystrokes to remote servers without meaningful encryption. The argument that a given company’s privacy policy protects you only holds if that company is never hacked, never acquired, never changes its terms, and you read and understood every clause before tapping “Accept”. Most people don’t.
For an adult who wants to install Grammarly on their personal phone and has made an informed choice, that is their call. For a child’s device — particularly a device that might also be used by parents, contain family photos, or share network access with home banking — the calculus is different.
The concern isn’t hypothetical. It’s exactly why school IT policies often prohibit third-party keyboards on shared or managed devices.
Where this feature came from
ChatMinder’s Message Improvement feature wasn’t built from a product checklist. It came from a real conversation.
A family member — an adult — mentioned that spell check was making their messages harder to understand, not easier. The problem wasn’t misspelled words. It was the right spelling of the wrong word.
“Thought” instead of “through”.
“Were” instead of “where”.
“Their” instead of “there”.
Spell check sees a correctly spelled word and moves on. But for someone with dyslexia, the phonetic similarity between two words is exactly the trap. The message looks fine to the person sending it. The person receiving it has to figure out what was meant. And rereading your own message minutes later — knowing it didn’t say what you intended — is a particular kind of frustrating.
That conversation became the foundation for Message Improvement: a writing assistant built directly into the chat composer, designed to catch exactly this kind of problem — without requiring a full-access keyboard permission or any data ever leaving the context of the message being written.
What it can do
Tap the ✨ magic wand button in the chat composer to open Message Improvement. A sheet appears with options:
- Fix Grammar — corrects grammatical errors and awkward phrasing
- Fix Spelling — catches wrong-word substitutions that spell check misses
- Expand — adds detail and context to a short message
- Shorten — trims a message to its key points
- Simplify — rewrites in plain, easy-to-understand language, which is particularly useful for users who find formal or complex language harder to process
- Change Tone: Friendly — makes messages warmer and more approachable
- Change Tone: Formal — adjusts to a more professional style
- Change Tone: Casual — makes messages feel relaxed and conversational
These are exactly the kinds of tools that genuinely help people with dyslexia, SEND, and communication differences — not as accommodations bolted on after the fact, but as features built for the way they actually write and communicate.
Why it’s different to a keyboard app — in one sentence
Message Improvement only ever processes the message currently typed into ChatMinder. It has no access to any other app, any other input, or any other data on the device.
When you tap the magic wand, ChatMinder sends the message text to our AI service and returns a suggested improvement. That’s the entire scope of the operation. There is no background process. No keylogging. No persistent permissions. No “full access” required — or granted.
For a parent who is already concerned about how much data their child’s apps are collecting, this is not a small distinction.
Guardian controls
Because ChatMinder is built around parental oversight, guardians control whether Message Improvement is available to each protected user individually. It is off by default — you have to explicitly enable it for each child.
To turn it on: Supervision Dashboard → select the protected user → Feature Protection → Message Improvement toggle.
When it’s disabled, tapping the magic wand shows a prompt asking the child to speak with their guardian — which keeps the guardian in control of which AI features each child can access, and gives parents and carers a natural conversation point.
This matters for SEND contexts in particular. Some children or young people benefit enormously from AI writing assistance. Others might find it disorienting if a message is rewritten in a way that no longer sounds like them. Guardians can make that call, per child.
Accessibility in ChatMinder — the bigger picture
Message Improvement is part of a broader set of accessibility features that have been built in direct response to feedback from real users and families:
Message Editing — made a mistake after sending? Tap and hold to edit. There’s no ticking clock of embarrassment. Edited messages go back through the same approval process as new ones.
No Pressure features — read receipts, last seen, typing indicators, and online status are all off by default. This removes the social pressure that makes messaging genuinely distressing for some children, particularly those with anxiety or autism.
Drawing messages — for children who communicate better visually, or who find typing stressful, the drawing canvas lets them send a handmade image instead of text.
Message styles — visual expression built in. No keyboard permission required.
These features were built because the families using ChatMinder asked for them — not because they appeared on an accessibility framework checklist.
Who can use Message Improvement
Message Improvement is a Premium feature, available to users with an active Premium subscription — including both guardians and protected users (with guardian permission enabled).
If your family could benefit from it and a subscription isn’t currently possible, get in touch — we would rather find a way to make it accessible than have it be the reason someone can’t use it.
The bottom line
Third-party keyboard apps are useful for adults who have made an informed choice about the trade-off between capability and data access. For children — and particularly for children whose devices are also used by their parents, or who are already navigating complex relationships with technology — a device-wide, full-access keyboard app is a meaningful security risk.
ChatMinder’s Message Improvement does the same job inside the safety of the app itself, under guardian control, with no access to anything outside the message being written.
It came from a real family’s real experience. It’s for the children who need it most.
