A writing system with teeth.
This isn't a generic plugin. Its rules engine and writing method are built in-house, not off the shelf — and the voice it locks in is yours.
Lock your project's voice into a config every skill enforces, then draft, refine and repurpose against it. It goes further than a style guide: it won't draft a topic until it has an angle only you would take — so nothing you publish reads like everyone else's. Nothing drafts until your rules exist, and the writing gets sharper the more you use it.

Most tools hand you a style guide and hope you follow it. Copylock enforces yours.
Most AI-writing tools clean up after the fact. A rewriter like PaperBleach takes finished AI text and rewrites it to slip past detectors — but the words are still the model's, just disguised. Copylock works at the source, inside Claude: it drafts in your voice, to your rules, from the first line.
Nine skills. One enforced voice.
Start with voice-setup; it writes the two config files every other skill reads. Add the learning loop and the distribution skills when you need them. New in 1.1: clear-writing now spots 23 patterns that make writing read as AI, and flags them only when several appear together.
Start here. A ten-minute interview builds your voice config — how you want to sound, your hard rules, and a sample you approve. Nothing else runs until it exists.
Clarity over compression — cut the jargon, keep drafts reading like you wrote them. It also spots 23 patterns that make writing read as AI, and flags them only when several pile up together.
Draft a long-form piece against your config: one idea, one search phrase to rank for, headings that guide the reader, and a final gate only you can pass before it ships. It won't start until the topic has an angle only you would take — so you never get a polished piece that says nothing.
Line-level suggestions against your rules. Never auto-applied — you accept or reject each one.
Compares what it drafted with what you published, finds what you keep changing, and proposes rule updates for you to approve.
Turn one approved article into posts written for each platform — every field filled in and ready to paste, not a link dump.
Cold emails built from a real reason to reach out and checked against your rules — outreach that reads like a person and earns a reply.
A keyword-led plan for what to write: topics grouped into themes, one search phrase per piece, built so the articles keep earning traffic long after you publish.
Angles Pro. Map the material your ideas come from and the angle you take on every question people search — so your backlog fills with points only you would make, not generic subjects. Supersedes the one-line angle in Core.
Three steps, then it compounds.
Lock your voice
Run voice-setup. It writes VOICE-RULES.md and copylock.json into your project — the rules every skill reads.
Draft and refine
Write with your rules enforced, not suggested. Nothing publishes until you, the copy gate, sign it off.
Let it learn
Edit as you normally would. learn-from-edits watches the difference and proposes rule changes you approve.
What enforcement actually looks like.
Copylock runs inside Claude. Four moments show what it does: it won't draft a topic until you give it an angle only you would take; it writes your voice into rules every draft obeys; it checks each line against those rules, and nothing changes until you accept it; and it turns edits you repeat into new rules you approve.
