Handshake deals fail at the point of proof.
Informal agreements collapse into conflicting memories about price, scope, delivery, and payment. Sigil makes the shared understanding visible while both parties are present.

FAQ
Clear answers.
Is a verbal agreement binding?
Sometimes. It depends on applicable law, transaction, capacity, consent, required formalities, execution, and jurisdiction.
Can Sigil guarantee enforcement?
No. No software can guarantee enforceability, admissibility, or acceptance by a court.
Does Sigil replace a lawyer?
No. Use qualified local counsel for high-value, regulated, unusual, or jurisdiction-sensitive matters.
Is recording consent required?
Yes. Local rules differ, so users must comply with law where each participant is located.
What if the AI misunderstands?
Both parties inspect and correct every term before approval. The AI drafts; people decide.
How does country detection work?
A minimal IP lookup is attempted, followed by browser language. Detection is approximate and always manually overridable.
Agreement and eligibility
These Terms govern Sigil’s website, beta, applications, and services. If acting for an organization, you confirm authority to bind it.
Documentation, not legal advice
Sigil assists with consent, term extraction, drafts, review, approval, and records. Outputs are not guaranteed enforceable, admissible, complete, or suitable for every transaction.
Recording and consent
You must provide notice, obtain every consent required by applicable law, and stop when consent is withdrawn. Covert surveillance is prohibited.
User review and formalities
Users must review every term. Sigil does not bypass writing, signatures, witnesses, notarization, stamping, registration, filing, or professional-advice requirements.
Privacy and processing
Supported devices process audio locally by design. Optional export, backup, messaging, or integrations may transmit data at your direction.
Beta, fees, and taxes
Beta features may change. Final paid pricing and billing terms will appear before purchase. Localized prices here are estimates.
Records and hashes
Hashes may indicate later content changes, but do not prove truth, identity, valid consent, legal capacity, or enforceability.
Governing terms
Mandatory local law and non-waivable consumer rights apply. Final governing-law and dispute terms will appear before paid activation.
