FlagCheck is an AI chat analyzer for text message screenshots. Upload a conversation and see the red flags, the hidden meaning behind each message, any scam warning, and what to reply.
You have read the message six times and you still cannot tell what they meant. FlagCheck reads the chat and tells you what is happening underneath it — the intent behind the wording, who holds the power, and how long they made you wait before replying.
WHAT IT READS
• Hidden meaning, line by line — what each message is doing, not just what it says
• Red flags and toxic patterns — gaslighting, breadcrumbing, love bombing, mixed signals, silent treatment, ghosting
• Effort balance — who is carrying the conversation, measured rather than guessed
• A response score for how one-sided the exchange has become
TELL IT WHO YOU ARE TALKING TO
Crush, partner, ex, friend, someone from work, or a stranger. The same sentence means something different from each of them, so the reading changes too: with a boss or recruiter it weighs the power gap, with a stranger it checks for fraud first.
THREE REPLIES THAT SOUND LIKE YOU
Three drafts for the situation: a sharp mirror, a firm boundary, and a clean closure. Each one is written in your own texting style — your slang, your spelling, your length — so it reads like you typed it, not like an AI did. Copy the one that fits and send it.
SCAM AND FRAUD DETECTION — FREE FOR EVERYONE
Online fraud usually arrives as a message, not a virus. FlagCheck flags the known shapes:
• A friend's account suddenly asking for a money transfer
• "My number changed, save this one" — the account takeover opening
• Urgency paired with a request to keep it secret
• Someone asking for an OTP, PIN, or verification code
• A payment redirected to a different name or account
• Fake prizes, fake invoices, fake customer support, a "bank" or "courier" that is not one
It never declares someone a scammer. It names which patterns matched and tells you how to verify — call them on a number you already had. This warning is never behind a paywall.
WORKS WITH ANY MESSAGING APP
WhatsApp, Instagram DM, Telegram, Messenger, iMessage, LinkedIn, Slack, email, Tinder, Bumble, Hinge, LINE, Discord, SMS. Chat bubbles are not required — flat message lists, email threads and one long message are read too. If you can screenshot it, it can be read.
FOR THE CONVERSATIONS THAT KEEP YOU UP
A crush who takes eleven hours to reply. A dating app match who went quiet after the first date. An ex who resurfaces at midnight. A partner whose "I'm fine" is not fine. A friend who only texts when they need something. A manager whose "quick call?" arrives at 10 pm. A stranger who got very friendly very fast.
BUILT SO YOUR SCREENSHOTS STAY YOURS
• No account. No email, no password, no sign-up.
• Black out names, faces and numbers before anything leaves your phone — the marks are burned into the image, not laid on top of it.
• Your screenshot is never stored. It lives in server memory for the length of the request and is released when the answer comes back.
• Results are saved on your phone and you can erase them all from Settings.
LONGER CONVERSATIONS
Send up to five screenshots at once and they are read in order, as one conversation.

WHAT THIS IS NOT
FlagCheck reads text and offers a probabilistic reading of it. It is not a lie detector, not a diagnosis, and not a replacement for talking to a professional or to the person themselves. Treat it as a second opinion, never a verdict.
Available in English, Bahasa Indonesia and Español.
