Image and video decision
Elai.io
A single developer can build a narrow text→avatar talking-head renderer using open-source components (TTS + Wav2Lip + ffmpeg) but reproducing Elai’s full product (avatar library, voice-clone polish, translations, enterprise features, and UI polish) is large and operationally intensive, so keeping the paid product makes sense for teams needing scale or enterprise capabilities.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Convert text (or PPTX/URL) + voice into a talking-head/video render and deliver downloadable video
What it still won’t have
- Large curated avatar library and premium avatar/animation assets
- Polished UI/UX and editor features (AI Storyboard, templates)
- Enterprise features: SSO, SOC2, unlimited/enterprise SLA, premium support
- Scale, reliability, and optimized rendering performance of a commercial service
- Integrated commercial voice cloning and premium voices
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal AI talking-head video generator using Node.js (Express) + React admin/editor, Postgres, and S3 for storage. In scope: accept a text script or PPTX, run TTS (cloud or open-source) to produce audio, run Wav2Lip/face-animation to synchronize an avatar image/video with audio, assemble slides and transitions with ffmpeg, produce downloadable MP4, implement an API endpoint to create/render jobs, simple web editor to preview and trigger renders, user auth, minutes/credits tracking in Postgres, and background worker (Bull/Redis) for rendering jobs. Out of scope: building a large avatar marketplace, enterprise SSO, SOC2 compliance, premium voice training studio. Include error handling for failed render jobs, retries for transient failures, and unit/integration tests for API and render worker.

- Evidence score67
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
