About
You felt something was off — but after hearing their explanation, you thought "maybe they're right." Sound familiar?
HeldLine: Boundary is an app that helps you set healthy boundaries in relationships, with AI support.

It records your feelings before you talk yourself out of them.

▸ Record your first instinct
Capture that initial "something's not right" feeling with one tap. When you look back later, you'll have proof of how you actually felt.
▸ AI analyzes the conversation
Just paste the message or describe the situation. AI breaks down the structure, gives a fairness score, and suggests a reply that helps you set your boundary.
▸ Compare who you were then with who you are now
"I said that for your sake." "It's because I trust you." After hearing words like these, check whether your feelings have shifted. We never tell you what to think. You're the one who compares.
