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 tool sprawl and review cycles while keeping voice rights and brand approval in one place. For marketing and media teams producing multilingual voice content from samples and scripts, convert licensed voice samples, scripts, language and brand rules into reviewer-approved voice tracks and campaign deliveries. The benefit is a testable hypothesis, measured through approved voice tracks per production hour and corrections after brand approval; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect licensed voice samples, scripts, language and brand rules, then follow this sequence: 1. Replicate a speaker's voice from a short audio sample. 2. Generate voices and sound effects from natural language text prompts. 3. Produce audio outputs using voice inputs. 4. Adjust emotion, accent, rhythm, pauses and intonation in generated speech. 5. Generate speech in multiple languages and accents. 6. Clone voices across languages not included in training data. Resolve uncertain cases with qualified reviewers, approve reviewer-approved voice tracks and campaign deliveries, and measure approved voice tracks per production hour and corrections after brand 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 fixed sample length and licensed voice set; final voice rights and brand checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve speaker consent, source attribution, voice rights and usage permissions. Named owners approve substantive changes and publication scope. One fixed sample length and licensed voice set; final voice rights and brand 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 fixed sample length and licensed voice set; final voice rights and brand checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: replicate a speaker's voice from a short audio sample; generate voices and sound effects from natural language text prompts. Support the remaining modules with operator review: produce audio outputs using voice inputs; adjust emotion, accent, rhythm, pauses and intonation in generated speech. 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 voice samples, authorized scripts and permitted research sources. Cloud asset storage, audio-file import/export and campaign 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: Voice and script intake, Editable production preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for references, constraints 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 asset. Make the task-specific outcome reviewer-approved voice tracks and campaign deliveries visible beside its evidence, review state and value baseline.
