WhyPost is a fully autonomous content factory. 10 cron jobs. 5 AI agents. Posts every day to Instagram, TikTok, and YouTube. Zero Anthropic API costs — uses Claude Pro CLI as a subprocess, not the API.
WhyPost uses Claude Code CLI — the same $20/month Claude Pro subscription you already have — invoked headlessly as a subprocess. No API key. No per-token billing. The same intelligence at zero marginal cost. This is the core insight that makes the whole system economically viable.
10 cron jobs fire every morning without you touching anything. The pipeline executes, posts go live, performance gets logged. You check your analytics after the fact.
One script becomes three formats — a vertical Instagram Story, a YouTube Short, and a TikTok — each optimized for that platform's algorithm, aspect ratio, and caption style.
Remotion renders word-by-word karaoke captions synced to the millisecond. Not burned-in subtitles. Proper motion-graphics captions that match the audio beat for beat.
Five separate agents, each specialized, each independent. EXEL mines ideas. Script Writer writes. CLACK renders. Publisher posts. Calendar plans. Each one upgradeable without touching the others.

If WhyPost is useful to you, share it where it belongs:
- Discord: discord.gg/cQQckfnN — show what your pipeline is producing
- Instagram: instagram.com/whyed.music — tag @whyed.music
- Reddit: r/automation · r/LocalLLaMA · r/Python
WhyPost is open source and built to be extended. Each agent is a standalone Python module — drop in a new one, wire it to the Flask API, add a cron entry.
Good first contributions:
- New platform integrations (Pinterest, LinkedIn)
- Additional Remotion video templates
- EXEL scoring improvements (YouTube trending, Twitter/X)
- Mission Control UI enhancements
Open an issue or a PR. The pipeline runs every day either way.
