How do you find out your own email writing style?
Take two or more emails you have actually sent, and measure them rather than judging them: average sentence length, how often you hedge, whether you greet by name, how you sign off, and which words repeat. Those patterns are your voice. A single email shows a mood, not a habit, which is why one is never enough.
The tool above does exactly that. It counts first, in code, and only then interprets what the numbers mean and quotes the lines that prove it.
Why most writing analysis is worthless
Ask a chatbot to describe your writing and it will tell you that you are clear, professional and friendly. That is true of almost everyone who writes competent email, which makes it useless. It is not a description of you, it is a description of the genre.
It will also confidently give you numbers. Average sentence length, reading level, formality score. Those numbers are invented, because a language model does not count words, it predicts what a plausible answer looks like. The figure will be in a believable range and it will not be your figure.
So this works in the other order. Your text is measured in code first, and the model is handed those measurements and told not to contradict them. It is allowed to interpret and to quote you, and nothing else. If a trait cannot point at a line you actually wrote, it gets thrown away before you see it.
What you get
The numbers
Sentence length, email length, how often you ask questions rather than assert, how often you hedge, whether you greet by name, whether you sign off. All counted, not estimated.
The habits
Four or five things you do consistently, each with a line from your own email as evidence. This is the part people screenshot, usually because it names something they did not realise was a pattern.
The proof
A complete email written in your voice, replying to a client asking for a discount you are not giving. If the profile is right, it should feel slightly uncanny.
Questions
How does this analyse my writing voice?
It measures your text in code first: average sentence length, how often you ask questions, how much you hedge, whether you greet by name, how you close, and which words you lean on. Only then does a language model interpret those numbers and quote your own lines back to you. That order matters, because a language model cannot count, so anything it tells you about your sentence length without measurement is a guess.
Is this different from asking ChatGPT to analyse my writing?
Yes, in one specific way. A chat model will happily tell you your average sentence length and be wrong, because it is estimating rather than counting. Every number here is computed from your actual text before the model sees it, and the model is instructed not to contradict them. It also cannot fall back on generic descriptions like clear and concise, because those are rejected before you see the result.
Do you store the emails I paste?
No. They are sent to the analysis, the result comes back, and nothing is written to a database. Paste whatever you are comfortable pasting, and if an email contains something sensitive, edit it before you do.
Why does it need two emails?
One email tells you about one email. Two is the minimum for separating a habit from a one off, which is the entire point of a voice profile. Three is better, and the analysis will use a third if you add one.
What can I do with the profile?
Most people use it to notice something they did not know they did, which is usually the hedging or the autopilot phrases. If you want it applied rather than just observed, that is what Mailient does: it builds the same profile from your real sent mail and uses it to draft the replies you owe.
Is this a tone checker?
No, and the difference matters. A tone checker looks at one email and tells you whether it reads as rude or unclear before you send it. This looks across several emails you have already sent and describes the patterns that repeat, which is a different question: not is this email good, but what is my writing actually like.
Is it free, and do I need an account?
Free, and no account. Paste two emails, get the profile. There is no trial, no card and no sign-up wall, because a tool you have to register for is not a tool you would try out of curiosity.
