Send Check names wording that may escalate a conversation or sound accusatory, and explains alternatives. You decide whether to change it.

Find the words. Keep the choice.
For the message you keep rewriting, the reply you are unsure how to read, or the difficult thing you need to say. SignalKind helps you explore clearer wording before you choose what to send.
For a need you recognise.
Find the words. Keep the choice.
Ask for more time on a report without apologising for every sentence.
For the message you keep rewriting, the reply you are unsure how to read, or the difficult thing you need to say. SignalKind helps you explore clearer wording before you choose what to send.
What you can do.
Try a different tone
On eligible devices, explore calm, direct, warm or professional rewrites and choose the version that sounds like you.
Make sense of a received message
Decode offers possible readings of tone, requests and deadlines. Suggestions cannot establish the sender’s intention.
Start with a guided draft
Templates help with requests, boundaries, apologies and messages that are difficult to begin. The phrase guide adds searchable, clearer alternatives.
Keep useful tools close
Use the free keyboard in supported text fields, the share extension and shortcuts. Save or hold a draft when you would rather return to it later.
A small, real-world workflow.
An illustrative task you can adapt to your own circumstances.
Bring a draft
For example: “You still haven’t sent the report. I need it now.” This is invented demonstration text.
Check and choose
Read the wording notes. On a supported device, try a rewrite such as “Please confirm when the report will be ready.”
Send it yourself
Copy your chosen wording into the conversation, or save the draft and come back to it. SignalKind does not send messages for you.

Privacy and control
Message checking uses local rules. Supported rewrites and Decode run on the device with Apple Intelligence. The app does not require a SignalKind account or send your messages to a developer server. Saved app history is stored on your device. Copying and sharing happen when you choose them.
The app, share extension and widgets use a shared local container. The keyboard reads the active text field through iOS and does not request Full Access. Keyboard rewrites also depend on device support and available extension memory. Secure fields and some apps may restrict third-party keyboards.

Questions you might have.
Does it know what someone really meant?
No. Decode offers possible interpretations of the words provided. Context can be missing, and the sender’s intent cannot be known with certainty.
Will it work without Apple Intelligence?
Send Check, templates, the phrase guide and saved drafts work on supported iOS 18 devices. Rewrite and Decode need the eligible Apple Intelligence setup described above.
Is the keyboard really free?
Yes. The keyboard has ongoing free access, separate from the full app’s 14-day access window and paid subscriptions. Supported devices and text-field restrictions still apply.
What happens after the 14 days?
Choose a paid app plan to continue full-app access. Starting the local window does not make a purchase. Saved History remains available to read and copy, and the keyboard remains free.
One part of The 4.
Communication supports communicate with confidence. The other apps serve separate needs in the same life. Start with one, choose another when useful, and purchase each independently.
