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 fraudulent account and transaction losses while keeping legitimate users moving. For product and risk teams running sign-up, login and payment flows for apps and websites, convert device signals, behavioral events, transaction records and identity checks into reviewer-approved allow, block or challenge decisions linked to case evidence. The benefit is a testable hypothesis, measured through confirmed fraud loss per reviewed case and false-positive rate on legitimate users; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect device signals, behavioral events, transaction records and identity checks, then follow this sequence: 1. Collect device and browser signals to identify and track devices. 2. Identify and block automated bot activity. 3. Evaluate user or transaction risk instantly as events occur. Resolve uncertain cases with qualified reviewers, approve reviewer-approved allow, block or challenge decisions linked to case evidence, and measure confirmed fraud loss per reviewed case and false-positive rate on legitimate users 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 fixed event schema and approved signal set; final fraud decisions and account actions remain human. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve user privacy, source attribution, evidence accuracy and data permissions. Named reviewers approve account actions and enforcement scope. One fixed event schema and approved signal set; final fraud decisions and account actions 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 fixed event schema and approved signal set; final fraud decisions and account actions remain human. Implement one approved input format, a bounded representative case set and the first two task modules: collect device and browser signals to identify and track devices; identify and block automated bot activity. Support the third module with operator review: evaluate user or transaction risk instantly as events occur. Include source references, corrections, basic organization access, decision 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
Customer-owned authentication systems, event streams and transaction databases. Cloud storage, identity providers and alerting destinations. Start with file exchange and validate destination specifications before promising direct enforcement. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Risk policy and data sources, Live alert triage, Case review and decision log. Use a queue of open alerts, a large central case view, and a right-hand panel for signals, linked accounts and reviewer notes. Let users compare decisions against policy versions side by side. Display open, challenged, blocked and cleared states. Provide a client-facing summary link with evidence anchored to the relevant event. Make the task-specific outcome reviewer-approved allow, block or challenge decisions linked to case evidence visible beside its evidence, review state and value baseline.
