WisiTube — AI Faceless Video Studio
Part of the WiSiVERSE. Turn one topic into a complete animated faceless YouTube video:
script → voiceover → images → synced animation → timeline editing → WebM export + thumbnail + SEO pack.
Architecture
| Piece | Tool | Cost |
|---|
| Script, titles, tags, thumbnail concepts | Anthropic API via api/generate.js (Vercel Serverless Function) | pennies per video |
| Images | Pollinations.ai (Flux) — anonymous free tier | free |
| Voiceover (TTS) | Pollinations.ai openai-audio (voices: nova, alloy, echo, fable, onyx, shimmer) | free |
| Animation + sync + export | Internal canvas engine (Ken Burns motion, crossfades, subtitles) + MediaRecorder → .webm | free, client-side |
Sync works by design: audio is generated per scene, so each scene's exact duration is known
and the animation switch happens precisely when the narration for that scene ends.
⚠️ api/generate.js is a Serverless Function (handler(req, res), maxDuration: 60).
Never convert it to an Edge Function — the two signatures are incompatible.
Setup (Windows / PowerShell — run commands one at a time)
cd C:\Users\loren\Desktop\wisitube
npm install
Add the logos to /public:
logo-wisitube.png (navbar)logo-wisiverse.png (footer, from Brand fotos)
Local dev (the /api proxy only runs under Vercel):
npm i -g vercel
vercel dev
(npm run dev also works for pure UI work, but "Generate video plan" needs vercel dev or the deployed app.)
Deploy
git init
git add .
git commit -m "WisiTube v1"
git branch -M main
git remote add origin https://github.com/lorevis92/wisitube.git
git push -u origin main
Then on Vercel: import the repo and set the environment variable:
ANTHROPIC_API_KEY = your Anthropic key
No Supabase needed for v1 (everything is in-browser). Supabase becomes useful later for
saving projects, user accounts, or a render history.
Rate limits
Pollinations' anonymous tier has fair-use limits. The app already spaces requests (1.2s between scenes)
and retries. If a user hits limits anyway: Create → Advanced → paste a free token from enter.pollinations.ai
(stored in localStorage only).
Known constraints (v1)
- Export renders in real time (a 60s video takes ~60s) and the tab must stay visible — browsers throttle hidden canvases.
- Output is
.webm (YouTube accepts it). MP4 conversion via ffmpeg.wasm is a possible v2 feature.
- Best supported browser: Chrome/Edge desktop.
