Ask Flag.
The AI investigator for people you met online.
Drop a photo, paste a handle or a profile link, or just describe what feels off. Flag asks only what changes the result, then checks the public record. Facts are marked as facts. Guesses are marked as guesses.

AI investigator · online
I'm Flag. I check whether someone you met online is really who they say they are, using public information only.
Tell me what's going on, or drop a screenshot of their profile below. You don't need to have much.

Average report time
We built the algorithm that does this. It compares photos, handles, bios and public records across hundreds of sources at once, and it holds more pattern knowledge about fake profiles than a friend, a therapist or your own gut. It does not editorialise. It reports.
Free preview, no signup. Cancel anytime. They are never notified.
Searching their name all night tells you nothing.
You have looked at the same photos twice. The story still does not line up. Thirty seconds here closes that gap, and nobody knows you looked.
Every line is labelled, so you know what is proven.
Your friends give you opinions. This gives you the public record, sorted and sourced.
How we label
Each statement carries a tag: Verified Fact, Source-Supported, AI Inference, Red Flag or Unknown. If we could not confirm something, it says Unknown. We never fill a gap with a guess and hand it to you as evidence.
That is the whole product. Not a vibe about someone. A record you can check yourself, with the source link next to it.
Nobody is notified
No message, no contact, no trace on their profile. The check happens on our side.
Real findings before you pay
The free preview shows the score and the strongest finding we actually have. Not a blank teaser wall.
Four steps.
Nothing to install. No messages sent. No accusations made.
- 01
Send their photo, handle or link
A name, city or age narrows the match further, but it is not required.
- 02
The algorithm reads the public record
Social profiles, company pages, directories, mentions and archived snapshots. Nothing private.

The full file lists every finding, its source, and the questions worth asking.
You can do this by hand. It takes all night.
Most people try that first. This is what changes when you stop.
Doing it yourself
With Profile Flag
Hours of tabs, screenshots and reverse image searches
One photo or handle becomes one report in about 30 seconds
No way to tell if a photo is AI-generated or recycled
AI-photo and recycled-photo checks run on every report
Contradictions get lost between apps and conversations
Every claim is matched against its source and cross-checked
Nothing to keep, nothing to look at again tomorrow
A saved report you can delete whenever you want
22 platforms. Each tile says what we actually found.
Dating apps have no public directory. Nobody can search them, so we say so instead of faking a hit. Adult and creator platforms are checked on the full report.
Coverage board
6 confirmed matches of 19 checked
Every tile shows its real state. A tile only turns green when the page exists and names the handle — anything we could not verify says so.
Sample dossier · illustrative, not real subject data
Checking someone should not put you at risk.
- They never find out.
- Nobody is contacted or messaged. Nothing appears on their profile.
- Public data only.
- No private accounts, no hacking, no background-check databases. Only what is already visible, with the source shown.
- Your search stays yours.
- Reports sit in your account. Delete any of them whenever you want. We sell nothing to anyone.
Six labels. That is the whole system.
Most tools blend fact and guess into one confident paragraph. We keep them apart and show the gaps.
Verified Facts
Visible in your own evidence or backed by a stored source.
Source-Supported
A public result we found and link to, so you can open it yourself.
AI Inference
A pattern read, labelled as one. Never sold to you as proof.
Red Flags
Public signals worth pausing on. Not accusations.
Unknown
What we could not confirm either way. We say so.
Satirical Verdict
Blunt commentary on real findings only.
This is what you actually get.
Left, the profile as it looks. Right, the same profile after the check.

Questions people actually ask.
What is Profile Flag?+
You give us a photo, a handle or a profile link. Our algorithm checks the public record and returns one report. Facts are marked as facts. Guesses are marked as guesses.
How do I know if someone I'm chatting with is real?+
Reverse image search their photos. Ask for a live video call. Then run a check here, because the algorithm compares far more sources than you can open by hand.
What are the biggest red flags in online dating?+
They won't video call. Their photos exist elsewhere under other names. Money comes up. The story changes between messages.
Will the person find out I checked them?+
No. Nobody is contacted or notified. Nothing shows on their profile.
Is Profile Flag a background check?+
No. It reviews public data. It is not a consumer report and it makes no criminal claims.
How much does it cost?+
The preview is free with no signup. One report is $9.99 one-time. Watch is $14.99/month: 5 scans and weekly re-checks of up to 3 people, with an email when something changes.
Stop guessing.
Free preview, no signup, and they are never notified. If there is nothing to find, that is an answer too.
