Questions and answers.

CoThread is one place for the practical side of co-parenting: messages, a shared calendar and check-ins, shared between you and your co-parent.

CoThread isn't available yet. Join the early-access list and we'll email you when it is.

You'll start with a free trial when CoThread launches. If you're working with an attorney, ask them for a code: it extends your free period. Fee waivers may be available where courts allow.

Yes. Separate homes, a nesting arrangement or a setup all your own: CoThread doesn't assume any particular custody or living arrangement. It keeps the shared logistics in one place, whatever they look like.

Relay Mode, an optional add-on planned for a later release, gives your thread its own phone number. Your co-parent can text it from their phone, without an account. On their first text, they're told once that their messages are kept on a shared thread they can view.

CoThread AI+, also planned for a later release, lets you ask questions about your own thread, like when a pickup time was agreed, and get answers that point to the exact messages and events. It finds and cites; it never writes messages for you. Add-ons are always optional.

No. Once a message is sent, it stays as sent for both of you. If you need to correct something, you can add a correction beside it.

No. CoThread never rewrites your words, scores your tone or suggests changes. If you'd like a moment before something goes out, you can turn on “Confirm before sending,” or schedule a message for later.

You'll both see what changed, who changed it and when. If an event is deleted, it's still visible on the thread, marked as deleted.

When you arrive at an exchange, tap “I'm here,” and your co-parent sees where and when you arrived. Your location is shared only at that moment. CoThread never collects your location in the background or shares it live.

You and your co-parent see the same thread, and the same list of anyone else who has access to it.

Only if you invite them. You decide who has access, and both parents can always see which professionals do.

Yes. You can export it whenever you need it, for example to share with your attorney.

Every message, calendar change and check-in gets a digital fingerprint (a SHA-256 hash) the moment it's created, linked to the one before it. If anything were altered, it would show.

Before the app keeps anything, it tells you what it keeps, who can see it and for how long. Our privacy policy covers this website and the early-access list.

No. CoThread helps with the logistics of co-parenting. For questions about your case, talk to your attorney.

CoThread isn't an emergency service. If you or your children are in danger, call 911. For confidential support, the National Domestic Violence Hotline is available 24/7 at 1-800-799-7233.
