Questions
Do I need to know how to code?
No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.
What does it cost?
The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.
How long does it take?
The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.
Can I change it to fit my business?
Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.
More detailsHow the AI works, safeguards and what to build first
Reduce document turnaround time while keeping every signature, notarization and payment under named human approval. For law firms, in-house legal teams and operations managers handling contracts, notarization and cross-border documents, convert uploaded documents, signer identities, notary credentials, contract terms and payment details into a completed, audit-ready document package. The benefit is a testable hypothesis, measured through completed document packages per legal operations hour and corrections after signature or notarization; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect uploaded documents, signer identities, notary credentials, contract terms and payment details, then follow this sequence: 1. Generate contracts and NDAs from templates. 2. Detect variables in templates and auto-fill agreements. 3. Let multiple parties edit the same contract. 4. Verify signer identities before signing. 5. Capture electronic signatures with audit trail. 6. Route documents to a remote notary session. 7. Onboard notaries only in jurisdictions that permit remote notarization. 8. Support apostille certification for cross-border use. Resolve uncertain cases with qualified reviewers, approve completed, audit-ready document package, and measure completed document packages per legal operations hour and corrections after signature or notarization against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One approved template set and one notary jurisdiction; final legal review and notarization validity remain with qualified professionals. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve legal validity, source attribution, signature accuracy and usage permissions. Qualified legal professionals approve substantive changes and filing scope. One approved template set and one notary jurisdiction; final legal review and notarization validity remain with qualified professionals. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
What to build first
Pilot scope: One approved template set and one notary jurisdiction; final legal review and notarization validity remain with qualified professionals. Implement one approved input format, a bounded representative case set and the first two task modules: generate contracts and NDAs from templates; detect variables in templates and auto-fill agreements. Support the third module with operator review: let multiple parties edit the same contract. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.
What it can connect to
Client-owned document management systems, authorized identity providers and permitted payment processors. Cloud document storage, e-signature and notarization destinations. Start with file exchange and validate destination specifications before promising direct filing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Document intake and parties, Signing and notarization session, Payment and delivery. Use a document list for matters, a large central viewer for the active document, and a right-hand panel for parties, identities, notary status, payment terms and comments. Let users compare template versions side by side. Display draft, awaiting signature, notarized and completed states. Provide a client link with comments anchored to the relevant clause. Make the task-specific outcome completed, audit-ready document package visible beside its evidence, review state and value baseline.
