Dating for people who protect their streak

Your 500-day Duolingo streak, the three languages you are juggling, and your goal to watch films without subtitles are not just self-improvement - they are identity. And the algorithm understands that.

How it works for language learners

Import from Duolingo or Babbel. Upload the data download each app gives you, and we read your target languages, streak data, XP levels, and learning consistency. Nothing is shared raw - only derived signals. All opt-in, all revocable.

The algorithm understands that language learning exists in layers:

A target language has a difficulty tier (Category I-IV for English speakers), a learner population, and a proficiency level
Matching happens at every level - shared target languages, shared motivation, shared dedication
Streak length and XP velocity provide engagement data
Learning a niche language (Finnish, Korean, Welsh) is a far stronger identity signal than learning Spanish

Niche overlap > mainstream overlap

Both learning Spanish? That is a popularity 85 overlap. It is the most studied language on Duolingo. Both learning Finnish? That says something deep about who you are.

Mainstream

Spanish (beginner)

Popularity 85 → NicheWeight 0.15

Niche

Finnish (intermediate)

Popularity 4 → NicheWeight 0.95 (capped)

The algorithm also considers dedication. A 500-day streak in a Category IV language is an engagement signal that dwarfs a 10-day streak in Spanish. Consistency and difficulty multiply the niche weight.

What gets scored

Shared target languages weighted by how niche they are among learners on the platform

Streak length - daily consistency as an engagement depth signal. A 365-day streak is a lifestyle commitment

Proficiency alignment - both at intermediate level in the same language is more practical than one beginner and one advanced

Motivation overlap - travel, heritage, career, cultural interest. Why you learn reveals values

Method preference - apps, classes, immersion, tutors, conversation exchange

Polyglot signal - learning 3+ languages simultaneously is a strong niche identity signal

Example match

"You both study Japanese and Korean 400+ day streaks. Shared motivation: cultural interest and media consumption. Both at intermediate level (JLPT N3 equivalent). Learning method overlap: app + italki tutoring. Polyglot signal: both studying 3+ languages concurrently. NicheWeight for Japanese: 0.72, Korean: 0.81."

Not "you both use Duolingo." The actual languages. The actual commitment. The actual identity.

All opt-in. All revocable. We show signals, never raw data. Live links use an official API you authorise; file imports use the data export the service gives you; partner access needs the service's agreement; anything else you add by hand.
