AI you can put on the record has to prove what it says.

BYOAI builds the verification layer for AI. Every factual claim is checked against its source before anyone relies on it. Anything we can't prove is held for a person to review, and every verified claim gets a receipt you can show later.

Illustrative example, modelled on the Sworn Legal assistant checking a sample agreement. Each claim shows the quote it rests on; anything the document contradicts or doesn't support is held for a person, never guessed. Every verified claim is filed under its own receipt ID.

Checks a contract for terms that can't all be true, then runs the signing ceremony on the same record, so the certificate shows both who agreed and whether the document holds together.

For teams that can't use the cloud: the full stack on a dedicated machine in your office, with a local model and nothing leaving your network.

Also in the build

  • Ticket timeline: each help-desk ticket's history laid next to the chat and email around it, to show what was done and when.
  • Device actions with receipts: Intune and Jamf steps checked before and after, so a wipe or an app push is confirmed done.
  • Wallet ID check: verify a mobile driver's licence or other digital ID on your own server.
  • Agent approvals: AI agents pause before they send, pay, sign or delete anything, until a person says yes, and every call is logged.
  • Security monitor: watches API keys, spend and backups, and takes only the actions you approved in advance.
Fabric

Contracts that check themselves before anyone signs.

Fabric reads a contract into its parties, dates and obligations, finds the clauses that can't all be true at once, and runs the signing ceremony on the same record. Its certificate reports two things separately: whether everyone agreed, and whether the document holds together.

Certificate of completionSample agreement
ExecutionComplete

Both parties gave consent and intent, each recorded against the exact version of the text they saw.

DocumentBlocked · term conflict

§ 3.1 runs the initial term 36 months, to 2029-01-15. § 11.4 ends the agreement 24 months after the Effective Date, on 2028-01-15. Both can't hold, so Fabric names the two clauses and leaves the choice to the parties.

Change one word in the record and the certificate no longer checks out.
  • Finds terms that can't all be true

    Conflicting term lengths, notice-and-cure deadlocks, deadlines with no fixed date, deadlines that can't be met in time, duties that outlive the contract, and cure periods that disagree. Each finding names the clauses involved.

  • Signing on the same record

    An ESIGN and UETA signing ceremony where consent and intent are tied to the version each person saw. Steps can carry a time stamp from an independent authority, and anyone can check the record offline, without us.

  • Agents stay inside their authority

    An AI agent can accept a change only within the limit a person gave it. Anything above that limit is held for a person.

How we build

Rules the product doesn't bend.

  1. The checker is not the writer

    Verification runs separately from the model that wrote the answer, so the two can't share the same blind spot.

  2. No quote, no green

    A claim is marked verified only when a passage in your source supports it, and that passage is shown with the answer.

  3. Unsure means held

    When the evidence is missing or unclear, the claim is held for a person. Uncertainty can block a verdict; it can never grant one.

  4. Every verified claim leaves a receipt

    Each verified claim is filed under its own receipt ID, so you can show later what was checked, against what, and when.

  5. Checked before it lands

    Claims are checked before the answer reaches you, not audited after someone has already relied on it.

  6. The professional decides

    We check facts against sources. Judgment, advice and sign-off stay with the licensed person using the tool.

Who it's for

Built for teams without a big-firm IT budget.
