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 switching and re-recording while keeping voice direction and rights under the team's control. For producers, studios and creative teams making narrated multimedia projects, convert approved scripts, voice references, direction notes and usage permissions into reviewer-approved expressive voiceover tracks linked to the final mix. The benefit is a testable hypothesis, measured through approved voiceover minutes per production hour and corrections after mix approval; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect approved scripts, voice references, direction notes and usage permissions, then follow this sequence: 1. Convert approved script text into spoken audio. 2. Synthesize natural speech with emotional expression. 3. Set pacing, emphasis, intonation and delivery style. Resolve uncertain cases with qualified reviewers, approve reviewer-approved expressive voiceover tracks linked to the final mix, and measure approved voiceover minutes per production hour and corrections after mix 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 voice direction, rights clearance and mix approval remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve voice likeness consent, source attribution, quotation accuracy and usage permissions. Voice owners and producers approve substantive changes and publication scope. One approved voice set and language list; final voice direction, rights clearance and mix approval 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 voice direction, rights clearance and mix approval remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: convert approved script text into spoken audio; synthesize natural speech with emotional expression. Support the third module with operator review: set pacing, emphasis, intonation and delivery style. 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 samples and permitted music sources. Cloud asset storage, video-editor 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 production preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for voice references, direction notes and comments. Let users compare takes 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 expressive voiceover tracks linked to the final mix visible beside its evidence, review state and value baseline.
