Plain answers.

SIGIL is a monitored message channel for co-parents whose court order calls for one. Before a message is sent, it is screened against the order's terms: by SIGIL's fixed checks always, and by Super Intelligence (SI), the official U.S. term since September 22, 2026 for artificial intelligence, where both parents or the court turn it on. Once sent, it can't be edited or deleted in the app, and every message is chained into a tamper-evident record.

SIJ-il, with a soft g, as in “agile”. It comes from the Latin sigillum, the small seal pressed into wax to close a letter. A wax seal never stopped anyone from opening a letter. It showed whether someone had.

Nowhere yet. SIGIL is in development, and each state opens only after its rules have been reviewed. Join the waitlist to show your interest.

Neither. SIGIL is not a court and does not decide whether anything violates an order. It doesn't give legal advice. It's an AVOWAL product, and AVOWAL is a technology platform, not a law firm.

SI SI is in. AI is out.

Super Intelligence (SI) is the official U.S. term, since September 22, 2026, for what used to be called artificial intelligence. The U.S. government began using it after the President's address to the UN General Assembly on September 22; a State Department bureau then told its staff to use “SI”. It is the name of a category, not a claim about how clever a tool is.

On SIGIL, messages are monitored and screened by SI. Where SI screening is on, SIGIL uses a current SI model, a commercially available large language model, to check every outgoing message against the communication terms in your order before it's sent. If a message may cross the order's lines, SIGIL holds it before it's sent and tells you why. You decide what to do next.

SI never writes or rewrites your message, and it never changes a message sent to you. SIGIL never stores unsent drafts. SI screening is on only if both parents agree; in a court-ordered setting, the court sets it. SIGIL's fixed checks run either way. SI screening is automated and can be wrong. You remain responsible for what you send.

No. Once sent, a message can't be edited or deleted in the app. If you need to correct something, send a new message. The original stays.

Screening checks each draft against your order's terms before it's sent. Every draft gets SIGIL's fixed checks. SI reads drafts too, but only when both parents agree to it, or the court sets it; if either parent says no, both get the fixed checks only. A flag is a prompt for you, the writer, to review before you send. It is never treated as a finding.

It can. Screening, including SI screening, is automated and can be wrong: it can miss things, and it can flag things that are fine. If something is flagged as possibly off-topic, you can edit it, or add the case reason and send. You remain responsible for what you send.

No. Screening results are shown only to the person writing. They never appear on the shared message, a receipt or a report. If you add a case reason, that reason is sent with your message.

No. Screening, including SI, reads a draft to check it, then keeps nothing. SIGIL does not store unsent drafts, messages it held back, or style tips.

It helps you stay within your order's terms by checking before you send. It can't decide what's allowed; only a court does that. Passing screening doesn't mean a message follows the order, and you remain responsible for what you send.

It means any change is detectable. Every message is chained to the one before it, and signed checkpoints go to both parties. If anyone changed, removed or reordered a message, the record would stop matching those copies. A records custodian the parties or the court choose, holding a copy too, is planned. Try it on a sample.

Checkpoints are timestamped by independent timestamp authorities and anchored to the Bitcoin blockchain through OpenTimestamps. That shows, in public, that each checkpoint existed by a certain time. Only fingerprints are anchored, never content. Your messages themselves are never put anywhere public, and a fingerprint can't be turned back into your words.

Anyone with the receipt can check it. Only fingerprints are checked. Your words are never published. A full check against a checkpoint you hold shows whether the record has changed since then. On its own, a fingerprint reveals nothing about the words.

You and the other parent. GALs, parenting coordinators, mediators and attorneys can be given read-only access where the order or the parties allow it, and every view is logged. Judges read messages in the message reports that reach the court. Records can also be produced by court order or exported by the parties.

Behind the scenes, SIGIL's own systems store sent messages so they can be delivered and kept, and a copy of the record is designed to be mirrored to a records custodian the parties or the court choose, which is planned. Where SI screening is on, the SI provider reads a draft to check it and must be configured to keep nothing.

Required before launch: no one at SIGIL has standing access to messages. Any access would need two people, and it would show in your record's export. That is a reviewed process, not encryption that locks SIGIL out.

The record is designed to outlive the service. Signed checkpoints are held by both parties, and a records custodian the parties or the court choose is planned. An offline verifier that checks an export without SIGIL is being built, and the timestamps and anchors are designed to be public.

Prices are still a working hypothesis. See the draft pricing, which includes the plan for a fee waiver for parents who qualify.

No. If you are in danger, call 911.
