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 narration production and review cycles while keeping one approved voice and script per language. For marketing and content teams producing narrated audio in several languages, convert approved scripts, brand voice rules, pronunciation lists and language requirements into reviewer-approved narration masters linked to their scripts. The benefit is a testable hypothesis, measured through accepted narration minutes per production hour and corrections after approval; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect approved scripts, brand voice rules, pronunciation lists and language requirements, then follow this sequence: 1. Convert approved scripts into spoken audio. 2. Support multiple languages and dialects per project. 3. Select voices from a permissioned library. Resolve uncertain cases with qualified reviewers, approve reviewer-approved narration masters linked to their scripts, and measure accepted narration minutes per production hour and corrections after approval 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. One approved voice set and language list; final pronunciation and brand-tone checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve brand voice, source attribution, pronunciation accuracy and usage permissions. Named owners approve substantive changes and publication scope. One approved voice set and language list; final pronunciation and brand-tone checks remain editorial. 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 approved voice set and language list; final pronunciation and brand-tone checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: convert approved scripts into spoken audio; support multiple languages and dialects per project. Support the third module with operator review: select voices from a permissioned library. 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 scripts, authorized voice assets and permitted pronunciation sources. Cloud asset storage, CMS import/export and publishing 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: Script and voice brief, Editable narration preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for scripts, voice settings and comments. Let users compare language versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant audio segment. Make the task-specific outcome reviewer-approved narration masters linked to their scripts visible beside its evidence, review state and value baseline.
