Image and video decision
Narasi AI
A single-technical-user can build a useful short-video studio using available OSS (FFmpeg/moviepy) and hosted APIs; the vendor polish, scale, and any proprietary models/licensing are what you'd give up.

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. All Narasi AI alternatives, with the arithmetic →
What a replacement has to do
- User enters an idea → AI generates script → synthesize voiceover → fetch/assemble b-roll and captions → render short video
What it still won’t have
- Polish and UX of a commercial product (teleprompter UX, one-click workflows)
- Proprietary training data or fine-tuned models used by vendor
- Scale, reliability, and multi-user billing/credits system
- Curated B-roll and licensing deals the vendor may have
- Ongoing moderation, analytics, and platform integrations
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a single-tenant web app (React frontend + Node.js/Express backend) that generates short-form videos from an input keyword. Use OpenAI (or an LLM of choice) for script generation; ElevenLabs or open-source TTS for voiceover; an ASR provider (or Whisper) for captioning; Pexels (or similar) for stock b-roll; AWS S3 for media storage; and FFmpeg (or moviepy) for video assembly. Core features in scope: idea input and topic-tree generator, script editor, produce TTS voiceover, auto captions from audio, fetch and stitch b-roll clips, render downloadable MP4, simple account and storage for one user, and basic error handling. Out of scope: multi-user billing/credits system, enterprise SSO, analytics dashboard, mobile apps. Provide unit tests for backend logic, end-to-end test for render pipeline, and basic CI. Ensure retries for transient API errors, validate media uploads, and surface render progress to users.

- 5 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
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.
