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
For software vendors processing business financial documents, turn defined document types and customer field schemas into structured document data with source references. Address the recurring problem: document formats vary and break fixed extraction rules. The pilot measures field accuracy and cost per accepted document against the buyer's current method, before the larger build.
Choose the request type, collect declared facts and required documents, extract relevant fields, show missing or inconsistent information, let the submitter correct it, and route the complete package to an authorized reviewer. Start with defined document types and customer field schemas and finish with structured document data with source references.
How the AI works
Classify submitted material, extract candidate fields and draft clarification questions. Deterministic rules test required fields and formats. Keep uncertain extraction visible and preserve the original statement. Do not infer missing material facts.
Safeguards
Reconcile calculations to approved records. Keep proposed entries and payment actions under finance-team control. Never invent missing financial inputs. Validate source access and reviewer availability during the pilot. Maintain customer-level access, data deletion controls and a record of final approvals.
What to build first
Begin with software vendors processing business financial documents and one recurring use case. Build the first two modules: define extraction schemas; capture source coordinates. Provide operator assistance for the third module: validate field formats. Deliver structured document data with source references through a manual review queue. Perform other necessary full-scope functions manually during the pilot. Include all applicable access, accuracy and professional-review controls from the start.
What it can connect to
Accounting exports, invoice records and finance review processes. Case management, customer records, document storage and notification systems. Begin with an exportable review pack before automating destination writes. These are candidate integration categories, not verified supported connectors.
The screens in detail
Give submitters a mobile-friendly step-by-step form with document uploads and a visible completeness checklist. Staff see a queue with missing items and extracted fields. Place the original document beside each uncertain value. Show submitted, clarification required and ready-for-review states. In this product, the first view is schema designer, followed by extraction review and API usage.
