My AI Clone

In this series, an AI clone is the combination of three things: a voice that sounds like you (voice cloning), a video avatar that looks and moves like you (lip sync and facial animation), and a conversational layer that responds in your style (a fine-tuned or prompted persona). The series tests each layer separately, then asks whether the assembled result feels like a useful proxy for the person.

Yes, in two ways. First, your voice and face become biometric data — once a model is trained on them, the model itself is sensitive material. Second, the resulting clone is a tool that anyone with the model can use to impersonate you. Treat the model files like passwords: keep them on infrastructure you control, log access, and have a revocation plan.

For a hobbyist-quality clone, roughly $0–$50 per month — open-source voice models, free-tier video avatar platforms, and your own prompt engineering on top of a chat model. For a production-quality clone you would put on a website or in a podcast, expect $200–$1,000 per month depending on usage volume — premium voice (ElevenLabs, Cartesia), studio-grade video (HeyGen, Synthesia), and a managed conversational layer.

In the audio domain, yes — the top voice cloning engines now produce output that fools casual listeners and most automated detectors. In the video domain, no — even the best avatars have a recognizable "AI look" on close inspection (uncanny eye movement, slight lip sync drift). The conversational layer is the weakest link; a clone reproduces your voice and face but rarely your judgement.

Three workflows have held up in our testing: language localization (record once in English, generate the same talk in eight languages with your voice), evergreen video content (avoid re-recording when only a price or a date changes), and asynchronous communication (record short personalized clips at scale for sales or onboarding). Live conversational use is still mostly novelty.

That is the third experiment in the queue. The technical pieces (LLM persona prompts, fine-tunes on personal writing, retrieval over personal email and notes) all exist. The hard part is judgement: making the clone refuse questions you would refuse, hold positions you would hold, and admit uncertainty where you would.
