THE SPACE BETWEEN “YES” AND “SIGNED”
A handshake is a beginning.
Give it something
to stand on.
The price. The deadline. That one extra thing. It all feels clear when you’re talking.
Sigil helps keep it that way. Capture the terms while they’re fresh, so you can get on with the work — together.

“Just one more revision” deserves a conversation.

02Skilled hands.
Tradespeople & contractors
The extra circuit agreed in the hallway counts, too.
Keep the work, materials, and payment terms clear before the job starts.

Small businesses & suppliers
A quick phone call can set a whole delivery in motion.
Give quantities, due dates, and credit terms somewhere to live.
04Life’s big moments.

Good agreements belong everywhere.Building something? Let’s talk API
03 / TRUST IS IN THE DETAILS
Your conversation.
Your business.
A shared record should bring peace of mind.
That starts with how it’s made.
Two people. Two yeses.
Everyone consents before recording begins. Both people review and accept the same terms.
CONSENT AT EVERY STEPA record you can follow.
Timestamps, versions, and an integrity hash help show what was agreed — and whether it has changed.
A CLEAR AUDIT TRAILSomething solid to come back to.
When memories differ, a shared record helps you return to the terms. Sigil preserves the agreement and its history; legal enforceability and admissibility depend on the law and the facts.
What does Sigil actually do?
Sigil is being built to turn a consensually recorded conversation into a plain-language agreement. It identifies the parties, work, payment, dates, and conditions, asks about missing terms, and lets both people review and sign the same record.
Each person gets a copy with timestamps, version history, and an integrity hash. The walkthrough above uses illustrative data.
Does this make an agreement legally binding?
Not on its own. Enforceability depends on applicable law, the transaction, the parties, their capacity and consent, and how the agreement was executed. A voice is not an identity document, and recognition of a signing method varies by jurisdiction.
Sigil does not provide legal advice, replace a lawyer, or guarantee that a court will admit or accept a record. Documents such as wills or property transfers may need witnessing, registration, notarisation, or stamping that an app cannot satisfy for you.
Where is my conversation processed?
Sigil’s design processes the conversation on your device, rather than sending it to a cloud model for interpretation. Recording starts only after everyone consents. You decide when to share the resulting record.
What rules apply in my country?
- Oral agreements
- In most legal systems an oral agreement can form a binding contract, subject to specific exceptions.
- Electronic records
- UNCITRAL Model Law on Electronic Commerce, 1996 And the Model Law on Electronic Signatures, 2001 — the templates most national e-signature laws are built from.
- Usually needs more than an app
- Land, wills, powers of attorney and certain guarantees commonly require writing, witnessing, notarisation or registration.
General information, not legal advice. Which law applies to your agreement depends on the parties, the transaction and what you agreed — not on where you happen to be reading this. Laws change, and this summary is not a substitute for advice from a qualified lawyer in your own jurisdiction.
