1. Repair after friction

Every long-term relationship has tense moments. The signal that matters is whether the chat returns to its pre-conflict baseline afterward. Repair velocity — how fast sentiment and volume recover — is the single strongest predictor of durability.

2. Bidirectional curiosity

Question-asking is a pro-social behavior that's easy to measure. Healthy chats show both parties asking questions at similar rates. A one-sided ratio (one person asks, the other just answers) is a quiet warning sign.

3. Shared in-jokes

Recurring phrases, nicknames, and private jokes indicate a shared narrative. The word-frequency analysis surfaces these automatically — the words unique to your chat that appear nowhere else.

4. Timezone-adjusted steadiness

Raw volume fluctuates with life. What matters is steadiness after accounting for context — does the chat keep going through busy periods, travel, and stress, or does it only live in good weather?

5. Proportionate emotional range

A chat that's only positive is a performance. Healthy chats contain the full emotional range — disappointment, frustration, worry — without derailing. The analysis flags chats that are suspiciously positive as a pattern worth examining.
