Before / After
Examples
Too direct
Before
You missed the deadline.
After
It looks like the deadline has passed. Could you share an updated timeline?
Cold reply
Before
That will not work.
After
I do not think that approach will work as-is, but we could adjust it this way.
Apology
Before
Sorry, my mistake.
After
I am sorry for the mix-up here — that was my mistake, and here is how I will fix it.
Status update
Before
Still not done.
After
We are a bit behind on this. Here is where things stand and when I expect to wrap up.

We cannot do that.

We are not able to do that on your current plan, but here is an option that could work for you.
FAQ
Is my text stored or used to train AI?
We never store your text or use it to train AI. Your text is sent to an AI model to run the check and then discarded. We keep only an anonymous one-way hash to catch abuse, never the text itself.
Is it free to use?
Yes. You can check a set number of messages for free each day. When you reach the daily free limit, you can keep going in the Inki editor.
When do I need to continue in the editor?
You can run checks and read the top suggestions right here. Some suggestions and the full rewrite open in the Inki editor.
What kinds of messages can I check?
It is built for work email, but it works on any short message where tone matters — a Slack or Teams message, a reply to a customer, or a note to your manager. Paste up to 800 characters at a time.
How does it decide what sounds rude or cold?
Inki reads your text with a language model tuned for tone, flags spots that can come across as rude, cold, impatient, or too casual, marks each with a severity, and suggests a warmer version. Tone is a judgment call, so treat the findings as a second opinion.
Does it change what I meant to say?
The suggestions keep your point and only soften how it reads. You choose which ones to use, so nothing changes unless you apply it.
How is this different from the email rewriter?
Use the tone checker when you mainly want to know how a message will land. Use the professional email rewriter when you want the whole email rewritten in a polished tone.
Does it check grammar and spelling too?
No. It reports how your wording is likely to come across, not whether it is correct. For grammar and clarity across a full draft, keep editing in the Inki editor.
Can I use it as a general tone checker, not just for email?
It is tuned for email and short work messages, so a Slack note, a customer reply, or a message to your manager all work. For long documents, the editor is a better fit.
