AI tone analyzer: find the line that reads as annoyed before you send. Written read, not a label. 12,000 characters, 5 free runs every 24 hours.
The task
Paste a message and it reads back how the message lands: where it sounds colder than intended, where the register does not match the situation, and which specific phrase is causing it.
It runs on our AI server, so the text is transmitted. The allowance is 5 free runs per rolling 24 hours at up to 12,000 characters each, with no account required.
Expect this
Competing tone checkers answer with categories. This one answers with sentences. Here is the split so nothing surprises you after a run.
The task
Paste the whole message including the greeting and the sign-off. Both carry more tone than the body does.
Diagnose it
These are the patterns that come back most often, and none of them is a grammar error, which is why a grammar checker passes the message straight through.
A straight answer
Direct, with the ask inside the first two sentences. Keep warmth in the greeting and the close rather than distributing it evenly, because warmth in the middle of a message reads as softening and softening signals bad news.
If the analyzer reports that your message reads stiff, the usual cause is formality standing in for politeness. Shorten the request, keep the thank you, and the stiffness goes.
The reverse failure is rarer and worse. A message about an outage, a refusal or a missed deadline written in the same bright register as an announcement reads as unserious, and the reader concludes you have not understood how bad the situation is. Naming the reader in the instruction field is what lets the read account for that, because the same words land differently on a client who is already unhappy.
The cause
A model optimised to be broadly acceptable lands on a register that offends nobody and commits to nothing: level sentence length, hedged claims, an upbeat close whatever the subject.
That is why AI-drafted messages read as insincere rather than rude. The tone does not move when the content does, and the gap between the news and the voice delivering it is what a reader actually notices.
Straight answer
No. Tone is a signal about the writing, not evidence about the writer. Corporate human prose produces the same flat register constantly.
The analyzer is instructed never to claim certainty about authorship, and we make no prediction about a third-party detector's verdict.
In practice
Anyone about to send a complaint, a chase, a refusal or a correction, which is where the question is real rather than theoretical.
Support leads checking a reply template that will reach thousands of people, and managers checking an announcement that has to carry bad news without sounding either cold or falsely cheerful.
Paste it, run it, read the report. It names the passages setting the tone and explains what they convey.
No. There is no tone taxonomy on this route, so nothing is filed into a category.
No. One written read for the whole text, not a tone per sentence.
Yes. 5 free runs per rolling 24 hours, no account, no paid tier.
No. Some competing tone checkers advertise unlimited use. This one is capped at 5 runs per rolling 24 hours.
12,000 per run. Empty input is rejected before it reaches the model.
Yes. This is a server route. Consider that before pasting anything confidential.
No. Some tools sharing this keyword analyse pitch and speaking rate in audio. This one reads text only.
No numeric output. Tone is described in words.
No. It reads and reports. Rewriting is a separate route.
Most often clipped sentences after a long paragraph, an opener restating the other person's error, or a bare sign-off under a request.
Plain and direct with the ask in the first two sentences, warmth at the greeting and the close.
No extension and no integration. It works on this page.
No API and no batch mode.
The whole message, greeting and sign-off included. Those two carry disproportionate tone.
No. It is a property of the writing, not proof of who produced it.
No. We neither test against detectors nor guess their verdicts.
This answers how it sounds. The style analyzer also covers construction and structural repetition.
Yes. It reads whatever you paste.
The interface shows when the next one unlocks, 24 hours after the run that used it.
Yes, identically in any modern mobile browser.
English is what it is built and checked for. Others may work, with no guarantee.
