AI app for creatives · no coding needed
Managed synthetic voiceover production platform
Consolidate synthetic speech production into one owned platform while keeping voice rights and review under the team's control.
Made for: Creative teams, studios and audio producers producing voiceovers and spoken audio

What it does for you
The problem
Voiceover production is split across several rented speech tools, so teams juggle separate accounts, inconsistent voices and unclear rights over cloned voices and generated audio.
What it gives you

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
Consolidate synthetic speech production into one owned platform while keeping voice rights and review under the team's control. For creative teams, studios and audio producers producing voiceovers and spoken audio, convert licensed scripts, approved voice samples and delivery specifications into reviewed voiceover audio with a rights record. The benefit is a testable hypothesis, measured through accepted voiceover minutes per production hour and corrections after client approval; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect licensed scripts, consented voice samples and delivery specifications, then follow this sequence: 1. Convert scripts into spoken audio with natural-sounding voices. 2. Create custom voice profiles from consented audio samples. 3. Offer a library of voices for different styles and tones. 4. Generate speech in multiple languages and accents. 5. Produce audio quickly for near-real-time preview. 6. Expose an API for app and workflow integration. 7. Generate expressive intonation and emotional nuance. 8. Add non-verbal cues such as laughs, sighs and emphasis with tags. 9. Embed a traceable watermark in generated audio. 10. Provide the model for customization and self-hosting. 11. Offer an easy interface for generating and editing voiceovers. 12. Balance audio levels automatically. 13. Reduce background noise in recordings. 14. Process multiple audio files in batch. 15. Preview audio changes before export. 16. Transcribe spoken audio into text. 17. Identify and label different speakers in a recording. 18. Export in multiple file formats such as DOCX, PDF and TXT. Resolve uncertain cases with qualified reviewers, approve reviewed voiceover audio with a rights record, and measure accepted voiceover minutes per production hour and corrections after client 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. Voice cloning requires documented consent from the speaker; final pronunciation, performance and rights checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve speaker consent, source attribution, pronunciation accuracy and usage permissions. Named owners approve voice cloning, substantive changes and publication scope. One approved voice set and language pair; final pronunciation, performance and rights 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 pair; final pronunciation, performance and rights checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: convert scripts into spoken audio with natural-sounding voices; create custom voice profiles from consented audio samples. Support the remaining modules with operator review: offer a library of voices for different styles and tones; generate speech in multiple languages and accents; produce audio quickly for near-real-time preview; expose an API for app and workflow integration; generate expressive intonation and emotional nuance; add non-verbal cues such as laughs, sighs and emphasis with tags; embed a traceable watermark in generated audio; provide the model for customization and self-hosting; offer an easy interface for generating and editing voiceovers; balance audio levels automatically; reduce background noise in recordings; process multiple audio files in batch; preview audio changes before export; transcribe spoken audio into text; identify and label different speakers in a recording; export in multiple file formats such as DOCX, PDF and TXT. 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
Author-owned scripts, authorized voice recordings and permitted research sources. Cloud asset storage, audio editing 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 setup, Editable production preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central editing canvas with waveform and text alignment, and a right-hand panel for voice profiles, pronunciation rules, tags and comments. Let users compare voice 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 reviewed voiceover audio with a rights record visible beside its evidence, review state and value baseline.
