KNOTFREE.CHECKLAB.AI

Knotfree

Not who was wrong, but where it got tangled.

Upload a chat from a couple's fight, as screenshots or copied text, and the AI Tarae finds where the conversation got tangled. Instead of picking a side, it points out where both of you felt hurt, then shows a hurt-feelings index, what each of you really felt, and one line you can send today to make up.

Hurt-feelings index showing how the hurt splits between you

The tangled point and what each of you really felt

One make-up line you can send today

Cleanup and masking happen in your browser; sent chats are deleted within 24 hours
