Image and video decision
Mevro — AI brainrot video generator for TikTok, Reels & Shorts
A capable developer can build a usable single-video generator (script → TTS → captions → render) within weeks, but reproducing Mevro’s autopilot scheduling, curated asset library, polish and production-grade scaling would be substantially more work.

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 Mevro — AI brainrot video generator for TikTok, Reels & Shorts alternatives, with the arithmetic →
What a replacement has to do
- Turn one-sentence idea → LLM script → synthesize voice → generate captions synced to words → assemble 1080×1920 MP4 with character overlay and background music.
What it still won’t have
- Polished, trend-curated viral formats and scoring
- Built-in character & background library and curated gameplay assets
- Priority render queue and production-grade UX polish
- Autopilot daily scheduling & direct auto-upload orchestration
- Commercial support and guaranteed SLA
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AI short-video generator using Next.js + Node, PostgreSQL, and FFmpeg. Core features in scope: 1) Web form to accept one-sentence idea and select format (comment story / two-character), 2) Server integration with an LLM (OpenAI or HF) to produce a multi-line script, 3) TTS integration to synthesize line-level audio and store files, 4) word-level caption generation and timestamp alignment to audio, 5) video assembly pipeline using FFmpeg to composite transparent cutout PNG characters, background, music and captions into a 1080×1920 MP4, 6) a simple asset picker and one-click background removal (use a public API or open-source U2Net), 7) endpoints to render and download the MP4. Out of scope: full autopilot scheduling, commercial analytics/dashboard, multi-user billing, and curated gameplay libraries. Include error handling for API failures, retries for long-running renders, and automated unit/integration tests for the LLM, TTS, caption alignment, and FFmpeg assembly steps.

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.
