Co-parent alone or together. Filter harmful texts and keep clear records.

Reduce conflict. Protect your peace. Keep a clear record.
BestInterest is the AI co-parenting app recommended by clinical psychologist Dr. Ramani Durvasula, who called its approach to co-parenting communication “nothing short of revolutionary.” Whether you're co-parenting together or managing a high-conflict relationship on your own, BestInterest helps you focus on your children instead of the next hurtful message.
ONE PARENT IS ENOUGH
No court order or co-parent sign-up is needed to start. Solo Mode lets you use BestInterest independently, even if the other parent refuses to join. Keep a private journal, track schedules and expenses, get coaching, and export your records. When you're ready to move texts and calls off your personal number, Boundary Line gives your co-parent a dedicated number they can use from their regular phone.
YOUR AI BODYGUARD FOR MESSAGES
Message Shield reviews incoming messages before you see them. It filters hostile language and brings the practical point forward, so you can deal with pickup times and school details without absorbing every insult. The original message is preserved and available when you choose to read it. Message Shield is included with Protect and Protect Plus.
WRITE THE RESPONSE YOU WANT ON RECORD
Tone Guardian reviews your draft before you send it and offers an optional, editable suggestion for a calmer, more child-focused reply. Choose a clear everyday style or Grey Rock style for brief, factual responses. You always decide what to send. Tone Guardian is included with Protect and Protect Plus.
SET BOUNDARIES AROUND YOUR PHONE
Boundary Line, available on Connect and higher, routes ordinary SMS and supported phone calls through a dedicated BestInterest number. Your co-parent needs no app or account, and you don't have to share your personal number. Set call windows and choose whether incoming calls can reach you. Protect Plus adds voicemail and optional recording for supported calls.
Smart Silence, available on Protect and higher, lets you choose when non-urgent message alerts arrive. Check messages on your terms while likely urgent alerts still come through.
COACHING WHEN CONFLICT SPIKES
Ask the AI Coparent Coach how to respond to a difficult message, set a boundary, or bring a conversation back to the children. The Free plan includes three coaching sessions each day; paid plans expand that allowance.
RECORDS THAT STAND UP TO REVIEW
Keep original messages and available timestamps together with your journal, call activity, tasks, and expenses. Export supported data on every plan. Connect and higher add structured Verified Reports for an attorney, mediator, therapist, or court to review. Each report can include an optional Certificate of Authenticity so a reviewer can compare it with the original held by BestInterest. Courts decide admissibility.
PRIVATE SPACE. TRUSTED SUPPORT.
Your co-parent cannot see your private journal or hidden notes. You choose what to share with a lawyer, mediator, coach, therapist, or other trusted professional through BestInterest's sharing tools and Professional Portal. We don't run third-party ads.
BUILT FOR HIGH-CONFLICT CO-PARENTING
For parents dealing with intimidation, post-separation abuse, or simply exhausting exchanges, BestInterest creates distance from hostile messages while keeping the original record available. Move from reactive conversations toward calmer, child-focused communication—whether you're parallel parenting or working together.
