A record built for the way courts read records.
A monitored communication channel for high-conflict family matters. Before a message is sent, it is screened against the order: fixed-rule checks always, and Super Intelligence (SI) screening where both parents consent or a court order sets it. Reports use familiar, plain labels, the verification is printed on the page, and your client gets fair, plain-language terms.
Super Intelligence (SI) is the term the United States government has used since September 22, 2026 for what was called artificial intelligence. SIGIL's SI screening uses a commercially available large language model.
Reports that read like a record
A message report is produced by deterministic code, never by SI. Messages are reproduced verbatim. No screening result appears in any report.
- Familiar labels first: Message k of N, Sent, From, To, First Viewed, Subject, Attachments.
- Full timestamps with the offset and UTC, every time, so no one has to ask which time zone.
- Line-numbered bodies, so a filing can cite a message and a line.
- A page ID and the chain head on every page, and scope on the cover: how many messages are in range and which, if any, were left out.
- Verification on the last page, with the hashes printed, so the report can be matched to its export and checkpoint.
Checkpoint 000421 · verify at sigil.avowal.ai/verifyThree ways to check a report
Proof you can check, not proof you have to trust. A report can be checked three ways. Each one checks something different, and none of them shows who typed a message.
By eye
Each page prints the chain head. Compare its first and last eight characters with a checkpoint the parties already hold. That confirms which checkpoint the report cites. It doesn't check the words on the page; for that, check the export.
With the offline verifier
Being built: a single file that runs in any modern browser with no network connection. From the export, it is designed to recompute every fingerprint, link and checkpoint, and to check the timestamps and the Bitcoin anchor.
On the check page
The public check page runs the same record checks in the browser. Timestamps and anchors are left to the offline verifier, which is being built. Files never leave the device.
Read-only for the case
Attorneys can be given read-only access to their client's channel where the order or the parties allow it. You see the record. You can't change it.
- The shared record only: the same messages, times and checkpoints both parents see. No drafts, no screening results.
- Every view is logged, and the log is kept with the record.
- Read-only means read-only. You can't post in the shared thread, and access ends when the order says it ends.
What SI screening is, and isn't
- SI screening runs on each author's own outgoing messages, before sending, against the communication terms in the order.
- Fixed-rule checks run on every message. SI screening runs only where both parents consent or a court order sets it, and the order sets its scope.
- Each flag names the term and quotes the words. Flags are potential issues for human review, never findings. SI does not decide whether anything violates an order.
- SI holds; it does not rewrite. SIGIL never stores unsent drafts or messages it held back. Your client stays responsible for what they send.
- Results are shown only to the person writing. They are not part of the record, and no SI result or label appears in a report.
SI screening is automated and can be wrong. The sender remains responsible for what they send.
Terms written to be fair to your client
Fair, plain-language terms, the same for both parents. They are in draft; the principles are published now, and the final text will be published before launch.
What SIGIL is not
- SIGIL is not a court. It flags potential issues for human review and does not decide whether anything violates an order.
- SIGIL is not a law firm and does not provide legal advice.
- Whether a report comes into evidence is for the court in each case. SIGIL builds reports for the way courts read records.
