SocialFaktory

Build me a personal AI video factory to replace SocialFaktory. Requirements: - Node + Express + better-sqlite3; a localhost dashboard with a brief form (topic, tone, target duration) and a queue of generated videos. - Script step: send the brief to the Anthropic API and get back a hook line, a spoken script, and a visual prompt; keep the system prompt in prompts/script.txt so I can tune it without touching code. - Video step: submit the visual prompt to fal.ai's queue API for a text-to-video model with native audio, poll until done, download the mp4 into media/ and record the actual dollar cost per generation in the DB. - Review page: each finished video gets a player plus approve, regenerate, and discard buttons; nothing publishes without an explicit approve. - Publish step: on approve, POST the video and caption to my self-hosted Postiz via its public API (POSTIZ_URL and POSTIZ_API_KEY in .env) with a scheduled time · Postiz owns the platform OAuth; never call TikTok, Instagram, or YouTube APIs directly. - A node-cron tick retries failed generations 3 times with backoff and marks rows before submitting so nothing ever double-bills. - A running-costs box on the dashboard summing this month's model spend. - Out of scope: multi-brand workspaces, teams, analytics, auto-QA, and any direct platform integrations (say so in the README). - README: getting the two API keys, pointing at a Postiz instance, and what a single video roughly costs to generate.
