68%
of co-parenting conflicts start over text messages.

The fight you didn't have to have.
CoParentSage is a messaging app for two parents. AI catches the words that start fights — before you hit send. So the conversation about Jake's lunch stays about Jake's lunch.
The problem
One careless word and the whole week falls apart.
Co-parenting after separation is hard enough. Text messages — short, contextless, sent at 11 PM — make it harder. Every misread becomes a fight. Every fight becomes a custody risk.

parents say their ex "constantly" misreads their tone.

CoParentSage dataThe solution
We catch the message before it lands wrong.
The Sage reads what you typed, flags what will land badly with your specific co-parent, and offers a rewrite that says the same thing — without lighting the fuse.
ToneAccusatory → Neutral → Collaborative
TriggersWords your co-parent has reacted to before
SpecificityVague asks become concrete requests
TimingLate-night sends quietly scheduled for morning
What you typed
"Hi, I didn't like what you are feeding Jake for lunch. Can you give him healthier options"
The Sage coaches you
What you send
"Hi David — the fruit you've been packing is great, Jake mentions it. Would you be open to swapping the chips for cucumber slices? He's been obsessed lately."
How it works
Three taps between you
and a calmer week.
01
Write what you actually feel
No filtering. Just say it. We'll handle the rest.
02
We flag what will land wrong
Tone, trigger words, vagueness, timing — all of it.
03
Send a version that gets a yes
Same meaning. Wildly better chance of cooperation.

Little Jake doesn't need you and your ex to be friends.
He needs you to be parents.
Kids whose parents communicate well after separation are happier, healthier, and do better in school. That's not us — that's twenty years of research from Harvard and UVA.
