For the thirty seconds before you hit send.
Paste in a message you are about to send and Signalkind tells you what will land badly, names the exact words, and offers rewrites in a tone you choose. Paste in one you have been sent and it gives you the plain reading. Built for ADHD and autistic people, and useful for anyone who has stared at a message wondering how it will come across.




Send Check names what will land badly
Paste. Read. Decide.
Some messages take four hours to write. Some get sent in four seconds and cost you the rest of the week. Signalkind is for the thirty seconds in between, and it never sends anything for you.
Paste or dictate
Drop in a draft you are worried about, or a message you have been sent. There is a keyboard and a share sheet too, so you never have to leave the app you are in.
Read the check
Send Check runs instantly. It names the exact phrases that will land badly and says why. No score, and no verdict on you.
Decide
Take a rewrite in the tone you pick, edit your own, or ignore all of it and send what you had. The decision stays yours.
Send Check, running in this page.
Type or paste a message below. This is the same check the app runs, with the same rules and the same wording, working right here in your browser. Nothing you type is sent anywhere.
Nothing to check yet
Type a message above and the check runs as you write, exactly as it does on the phone.
This runs entirely in your browser. Nothing is uploaded, logged or stored.

See what will land badly, before they do
It does not give you a score. It points at the words. “Unacceptable” reads as a formal complaint. Capitals read as shouting whatever you meant. “Frankly” braces the reader for criticism. Each flag comes with what to do instead.
- Names the exact phrase, not a vague warning
- Runs instantly on any iPhone, with no internet connection
- Catches escalation, undermining, and personal attacks

Your tone, rewritten to land better
Three versions of your message in the tone you choose: calm, direct, warm or professional. Each one comes with a line explaining what changed and why, so you are picking a message rather than trusting a machine.
- Runs on your iPhone with Apple Intelligence
- Take one, edit one, or take none
- Nothing is ever sent for you

What did they actually mean?
For the messages you receive. It answers the question you actually have first, which is whether you are in trouble, then the tone, the deadline, what is being asked of you, and the phrases worth knowing. “Let us revisit this” usually means it is being shelved.
- The plain reading, with nothing read into it
- Tells you what needs doing and roughly how long it will take
- Explains the phrases that carry a hidden meaning

The message you cannot start
Thirty guided drafts for the ones that sit unsent for days. Asking for more time. Chasing something ignored twice. Apologising without spiralling. Telling family you are neurodivergent. Raising something with a school, a landlord or a neighbour. Fill in the blanks and it goes straight to Compose.
- Work, family and everyday admin, not just the office
- Written to be edited, never sent as they are

1,900 ways to say the hard thing
Clearer, kinder ways to say what you mean, each with the reason it matters rather than just a swap. Sorted by where you are stuck: work, parenting, relationships, school, therapeutic settings, everyday talk, writing, and disability and access.
- Search by a phrase or by a feeling
- Every entry explains why the wording matters
The keyboard is free forever.
Install the Signalkind keyboard and it checks your tone as you type, in every app on your phone. Mail, Messages, Slack, anywhere there is a text field. It flags what will land badly and rewrites it right there without switching apps.

No subscription. Not for fourteen days, not as a trial.
The keyboard is free, and it stays free. It asks for no network access and no Full Access, so it cannot see anything beyond the field you are typing in, and nothing it reads is sent anywhere.
- Works in every app with a text field
- Send Check and rewrites, without opening Signalkind
- No Full Access requested, so nothing can leave your phone
The keyboard is free forever. Whether or not you ever subscribe, and whether or not your trial has ended.
Fewer apps.
Everything below is part of Signalkind. No account, no sign up, and no server for any of it.
Nothing leaves your iPhone. No account, no sign up, no server, and nothing collected.

Park a message instead of sending it
If you rewrite the same angry message three times at midnight, Signalkind offers to hold it rather than watch you send it. It comes back in the morning, when you get to decide again. Nothing you write is ever deleted without you saying so.
- Hold any draft yourself, at any time
- Your history stays readable whether or not you subscribe
Fourteen days of everything.
The whole app, with nothing withheld and nothing counted, for two weeks. After that, pick a plan to carry on using the app itself.
The keyboard is free forever on every plan and on no plan at all. Your history stays readable either way, because the drafts in it are yours. Rewrites and Decode need Apple Intelligence; Send Check, templates and the phrase bank work on any iPhone running iOS 18.
Something not working?
Email signalkindapp@gmail.com and a person will read it. Tell us what you were doing and what happened, and if you can, which iPhone and which version of iOS.
We cannot see anything you have written. Nothing is uploaded, so please describe the problem rather than sending us the message.
