For families
A calmer way to put it in writing.
When your order says you have to communicate in writing, SIGIL keeps it simple. Say what you need about the case. Before it goes, every message is screened against your order by Super Intelligence (SI), when you both turn it on or the court sets it. Once it's sent, it can't be edited or deleted in the app, for either of you.
Screening is automated and can be wrong. You remain responsible for what you send.
Super Intelligence (SI) is the official U.S. term, since September 22, 2026, for what used to be called artificial intelligence. What is SI?
What it's like to use
Fewer things to worry about
The same simple thread for both of you, with the rules on screen and a check before anything goes.
- Your order at the top of every thread. The same words for both of you, so nobody has to guess the rules.
- A check before you send. SIGIL's fixed checks run on every message, and SI checks it too when you both turn it on. If something may be outside your order, you see it first, and you decide what to do.
- Tips just for you. Optional tips, like leading with the request. Never shown to the other parent.
- Sent and first-viewed times. Less guessing about whether a message arrived.
- The same record for both of you. Neither of you can change what was said in the app, and any change to the record is detectable. Nobody has to screenshot anything.
Super Intelligence (SI)
Screened by SI. Sent by you.
SI never writes or rewrites your words. You decide what to send.
SIWhat SI does
- Before your message goes, SI checks it against your order.
- If something may cross a line, SIGIL holds it before it's sent and tells you why.
- It flags things for you to decide. You decide what to send.
What SI never does
- It never writes or rewrites your words.
- It never changes a message sent to you.
- It never keeps your drafts. SIGIL does not store unsent drafts.
- It does not decide whether anything violates an order. Only a court does that.
Who turns it on
SI screening is on only if both parents agree. The same rules apply to both of you. If either of you says no, neither of you is screened by SI, and SIGIL's fixed checks still run. In a court-ordered setting, the court sets it.
SI screening is automated and can be wrong. You remain responsible for what you send.
Your privacy
What stays private
Unsent drafts aren't kept
Screening reads a draft to check it, then keeps nothing. SIGIL does not store unsent drafts or messages it held back.
Screening is just for you
The other parent never sees your screening results. They don't appear on the message, on a receipt, or in any report.
Only fingerprints are anchored
When a checkpoint is anchored, only fingerprints go out, never your words. Content is shared only as the parties or an order direct, and with the service providers that process it for SIGIL.
No ads, no tracking
SIGIL is designed with no advertising and no ad tracking. This website sets no cookies and runs no analytics.
Plainly
What SIGIL can't do
It helps to know the limits before you rely on anything.
- SIGIL is not a court. It does not decide whether anything violates an order. Only a court does that.
- SI screening can be wrong. It can miss things, and it can flag things that are fine. You remain responsible for what you send.
- SIGIL can't make anyone reply. It keeps an honest record of what was sent and when it was first viewed.
- SIGIL doesn't give legal advice. For questions about your order, talk to a lawyer or the court.
- SIGIL is not an emergency service. If you are in danger, call 911.
Cost
Cost shouldn't decide who can use it
SIGIL's prices are still a working hypothesis. The plan includes a fee waiver for parents who qualify, and reading and exporting your own record is planned to stay free.
In development
SIGIL isn't available anywhere yet. There's nothing to install yet and nothing to pay.
Say it once. It stays said.
