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 number of tools and review rounds needed to publish natural-sounding localized video. For marketing and media teams localizing video content for multiple language markets, convert licensed video, speaker audio, target-language briefs and brand constraints into reviewer-approved localized video versions with matched voice and lip movement. The benefit is a testable hypothesis, measured through approved localized versions per production hour and corrections after native-speaker review; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect licensed video, speaker audio, target-language briefs and brand constraints, then follow this sequence: 1. Detect the spoken language in each uploaded video. 2. Transcribe speech with speaker labels and timecodes. 3. Translate the transcript into each target language. 4. Clone the original speaker's voice for the dubbed track. 5. Adjust lip movement to match the dubbed audio. 6. Generate and style subtitles for each language version. Resolve uncertain cases with qualified native-speaker reviewers, approve reviewer-approved localized video versions, and measure approved localized versions per production hour and corrections after native-speaker review 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 source language and a bounded set of target languages per pilot; final meaning, cultural fit and brand checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve speaker voice rights, source attribution, translation accuracy and usage permissions. Named reviewers approve substantive changes and publication scope. One source language and a bounded set of target languages per pilot; final meaning, cultural fit 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 source language and a bounded set of target languages; final meaning, cultural fit and brand checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: detect the spoken language in each uploaded video; transcribe speech with speaker labels and timecodes. Support the remaining modules with operator review: translate the transcript, clone the original speaker's voice, adjust lip movement and generate subtitles. 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 video libraries, authorized speaker recordings and permitted research sources. Cloud asset storage, design-file 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: Source video and language brief, Editable localization preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central video player with a timeline, and a right-hand panel for languages, speakers, subtitles and comments. Let users compare source and localized versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant timecode. Make the task-specific outcome reviewer-approved localized video versions visible beside its evidence, review state and value baseline.
