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 manual document handling while keeping a named reviewer accountable for every extracted record. For operations teams processing high volumes of invoices, forms and scanned documents, convert supplied PDFs, images, scans and structured files into reviewer-approved extracted records linked to their source pages. The benefit is a testable hypothesis, measured through accepted records per operator hour and corrections after downstream posting; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect supplied PDFs, images, scans and structured files, then follow this sequence: 1. Extract key fields from supplied documents. 2. Classify documents by type. 3. Apply validation rules to extracted data. 4. Validate relationships between fields, such as totals matching. Resolve uncertain cases with qualified reviewers, approve reviewer-approved extracted records linked to source pages, and measure accepted records per operator hour and corrections after downstream posting against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. Final posting, payment and compliance decisions remain human. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve source attribution, field accuracy and usage permissions. Named reviewers approve extracted records and downstream posting scope. One document family and one approved export destination; final posting and compliance checks remain human. 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 document family and one approved export destination; final posting and compliance checks remain human. Implement one approved input format, a bounded representative case set and the first two task modules: extract key fields from supplied documents; classify documents by type. Support the remaining modules with operator review: apply validation rules to extracted data; validate relationships between fields, such as totals matching. 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
Buyer-owned document repositories, ERP and CRM systems, cloud storage and webhook endpoints. Start with file exchange and validate destination specifications before promising direct posting. 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 classification, Extraction review and validation, Export and system handoff. Use a queue view for incoming documents, a large central viewer showing the source page beside extracted fields, and a right-hand panel for validation rules, confidence and comments. Let users compare extracted values against source regions. Display draft, changes requested and approved states. Provide a webhook and export log view for failed validations and human-in-the-loop steps. Make the task-specific outcome reviewer-approved extracted records linked to source pages visible beside its evidence, review state and value baseline.
