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 the gap between a plain-language app concept and a deployed application the client owns. For small product teams and internal builders, convert a written concept, UI constraints and chosen AI models into reviewed generated code, a tested sandbox build and a deployed app on the client's domain. The benefit is a testable hypothesis, measured through accepted build increments per delivery hour and post-deploy defects; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect the plain-language concept, UI constraints, chosen AI models and target domain, then follow this sequence: 1. Turn a plain-language app concept into generated code. 2. Run and modify the app in a live testing sandbox. 3. Create ready-to-use API backends without manual configuration. 4. Scan apps for common issues before publishing. Resolve uncertain cases with qualified reviewers, approve reviewed generated code, a tested sandbox build and a deployed app, and measure accepted build increments per delivery hour and post-deploy defects against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate code and content 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. One target framework and one hosting provider; final architecture, security and release checks remain with qualified developers. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve source attribution, code ownership, license compliance and usage permissions. Named developers approve substantive changes and release scope. One target framework and one hosting provider; final architecture, security and release checks remain with qualified developers. 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 target framework and one hosting provider; final architecture, security and release checks remain with qualified developers. Implement one approved input format, a bounded representative case set and the first two task modules: turn a plain-language app concept into generated code; run and modify the app in a live testing sandbox. Support the remaining modules with operator review: create ready-to-use API backends; scan apps for common issues before publishing. 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 repositories, design files and permitted research sources. Cloud code storage, framework import/export and hosting destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Concept and constraints brief, Editable build workspace, Test and deploy console. Use a project gallery, a large central code and preview canvas, and a right-hand panel for models, packages, versions and comments. Let users compare versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant screen or code block. Make the task-specific outcome reviewed generated code, a tested sandbox build and a deployed app visible beside its evidence, review state and value baseline.
