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 ungoverned agent actions while keeping a reviewable record of every block and approval. For platform and security teams operating AI agents that call tools and internal systems, convert incoming prompts, retrieved documents, proposed tool calls and model responses into screened, policy-checked and logged actions linked to named-owner decisions. The benefit is a testable hypothesis, measured through blocked violations per reviewed action and unapproved actions reaching internal systems; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect agent configurations, policy rules, provider credentials and internal API specifications, then follow this sequence: 1. Screen incoming prompts before they reach the model. 2. Check every proposed tool call against policy and block violations. 3. Scan retrieved documents and knowledge base content for hidden instructions. 4. Validate agent output before it reaches end users. Resolve uncertain cases with qualified reviewers, approve screened, policy-checked and logged actions linked to named-owner decisions, and measure blocked violations per reviewed action and unapproved actions reaching internal systems 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 policy evaluation, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One fixed policy schema and supported provider set; final security and compliance decisions remain with the buyer's qualified reviewers. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve policy intent, source attribution, decision accuracy and usage permissions. Named owners approve substantive policy changes and enforcement scope. One fixed policy schema and supported provider set; final security and compliance decisions remain with the buyer's qualified reviewers. 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 policy schema and supported provider set; final security and compliance decisions remain with the buyer's qualified reviewers. Implement one approved input format, a bounded representative case set and the first two task modules: screen incoming prompts before they reach the model; check every proposed tool call against policy and block violations. Support the remaining modules with operator review: scan retrieved documents and knowledge base content for hidden instructions; validate agent output before it reaches end users. 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 agent frameworks, provider APIs and internal API specifications. Cloud secret storage, identity providers and audit 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: Policy and guardrail configuration, Live interception and decision log, Review and audit. Use a dashboard for connected models, MCPs and agents, a central stream of intercepted requests with decision state, and a right-hand panel for policy layers, evidence and reviewer notes. Let users compare detect mode against enforce mode side by side. Display allowed, flagged, blocked and approved states. Provide an audit export link with decisions anchored to the relevant request. Make the task-specific outcome screened, policy-checked and logged actions linked to named-owner decisions visible beside its evidence, review state and value baseline.
