How to export your chat ↓
Decode the Texting Chemistry
Staring at single messages will make you crazy. But the statistics of how you communicate don't lie. Relationship Lens scans long-term habits to separate anxiety from actual behavior.
Linguistic Sync
Human beings mirror those they feel close to. We calculate Language Style Matching (LSM) to measure how your pronoun usage, emotional adjectives, and slang sync up.
Dry Texting & The Effort Gap
Is one person yapping while the other drops single-letter replies? We measure words-per-message (Yap Share) and dry text rates to audit who is carrying the conversation.
The Response Lag
We calculate the median reply time for both users. Stop guessing if they are busy or pulling away—see their true baseline rhythm and response symmetry.
Initiation Share
Who pulls the thread forward after it goes cold? A healthy dynamic shares the workload; an asymmetric one has a permanent chaser.
Absolute Privacy by Design
Text histories contain your most intimate thoughts. Relationship Lens is built to be a vault with zero compromises:
Zero Servers. 100% Client-Side.
Unlike AI startups that upload your personal files to corporate servers, Relationship Lens processes every message locally in your browser. Your raw chat never leaves your device.
Try it Offline
Once the page loads, you can disconnect your internet entirely. The analyzer runs 100% locally on your browser.
No Tracking
We do not save, store, or sell your conversations. Period. No databases, no trackers, no cookies.
