About

Builderlog is a set of automation packs for creators. The YouTube Shorts and TikTok packs are available now in English, with more packs on the way. Each pack plugs into the AI tool you already use (Claude Code or Codex) through MCP. You paste one sentence into your AI chat to install it, so you never type commands in a terminal. How it works: ask your AI in plain words, like 'make a Short'. It picks a topic, writes the script, checks it against platform rules (ad disclosure, AI labels, title checks) and prepares the files. You review and publish. Who it is for: solo creators and small sellers who need to post every day but do not have time to research, write and check everything by hand. What sets it apart: packs are updated often, rules are checked before you publish, and everything stays as files on your own computer. Your AI tool and outside services are billed separately.
