Every night, you scroll.
And every night, your algorithm takes notes. Your humor. Your obsessions. Your 2am spirals.
Somewhere out there, someone's algorithm has been taking the same notes.
We built the thing that finds them.
Doppel is a dating app that matches people by their TikTok algorithm, not their photos. Right now we're testing the engine, and we need real feeds to test it on.
Single or taken, doesn't matter. This phase is a test, not a dating pool.
Every other app makes you build yourself from scratch. We just read what's already there.
No bio. No prompts. No pressure to be witty in 300 characters.
No staged golden-hour photos. Your feed can't be faked, and that's the point.
One match report that already knows. Not a thousand thumbs to wear out.
TikTok hands you a file of what it knows about your taste. Takes two minutes to request.
One private upload link. It goes straight to the matching engine and nowhere else.
Your taste fingerprint, your shared niches, and who in the test scrolls in sync with you.
It's your data, and TikTok hands it over whenever you ask. Here's the path.
TikTok's download link expires after a few days, so send it over soon after it arrives. Menu looks different on your version? Just search "download your data" inside TikTok settings.
Your raw file becomes an anonymous taste fingerprint, then it's deleted. Want out entirely? One message and everything's gone.
No black box. Four steps, all explainable.
Your export gets read once: interest categories, search terms, watch timestamps. After that the raw file is deleted.
structured parsingYour taste becomes a weighted vector across ~15 interest clusters. Rare niches count for more than viral trends, because pottery says more about you than a meme everyone's seen.
inverse-popularity weightingFingerprints are scored pairwise on how their clusters align, plus scrolling rhythm. Night owls sync with night owls.
cosine similarityThe match score peaks near 75% overlap, not 100%. The research is pretty clear that you don't want to date your clone. You want someone who adds a few new obsessions.
similarity sweet spotFiles land in restricted storage that only the engine touches. We'll confirm once it's in, and your match report comes back within a few days.
