For iPhone
Should you send this?
You have typed it, deleted it and typed it again. It is 1am, you have read it eleven times, and you genuinely cannot tell any more whether it sounds normal or whether it sounds like a lot.
SEND? is the friend you would show it to first. Paste the draft, say who it is going to, and get a straight answer — plus the exact words costing you, and four better ways to say the same thing.
The message you are about to send. Say who it is for — a crush, an ex, your boss — and what is going on.
SEND IT or DON'T SEND, one line on why, and the readings behind it.
Four rewrites in four registers, keeping every detail you actually wrote.
Why it isn't a writing assistant
It commits to an answer.
Ask a chatbot whether to send something and it will tell you that it depends, that both options have merit, and that you should do what feels right. That is not help. That is the same paralysis with more words.
SEND? picks one. Send it or don't, and a sentence naming the actual thing — the apology you opened with, the three days you mentioned, the question you never got round to asking. You can disagree with it. You cannot come away with nothing.
What you get
A verdict, then the evidence.
The answer, in one word
DON'T SEND in red, or SEND IT in green, with one line saying why — specific to this message, not to messages in general. Under it, the single reading that explains the verdict: the loudest thing in what you wrote, as a number.
Your own words, marked up
The draft comes back with the lines that cost you highlighted where they sit — so “sorry to bother” is not an item in a list further down, it is the third phrase of the thing you are about to send, glowing. Each one quoted back with the reason it lands badly.
Four ways to say it
Confident, flirty, casual and mysterious — genuinely four different messages, not one message with the adjectives swapped. Every concrete detail you wrote is kept: the place, the day, the plan. Nothing invented on your behalf.
Built to be screenshotted
Every verdict comes out as a card you can send straight to the group chat — with or without the message itself. Which is, if we are honest, what you were going to do anyway.
Pricing
Three checks, free.
The first three are the real thing, not a trial version of it — the full read, the phrases, the rewrites. After that, checking a message needs Pro.
Pro is $3.99 a week or $24.99 a year, which works out at about 48 cents a week. Prices vary by country. It renews until you cancel, and you cancel in the App Store rather than by emailing us.
Privacy
Nobody reads this but you.
There is no account and no sign-up, so there is nothing for a message to be attached to. Nothing you type is stored — a draft exists for as long as it takes to judge it, and then it is gone. There is no history to go back through, by design.
A full analysis is read once by our model provider and held briefly by them, tied to nothing that identifies you. Screenshots of a conversation are read on your phone; the picture is never uploaded. The full detail is in the privacy policy.
