Free. No account.
Paste one thing you have sent a client.
We will tell you how you make it — the spine you follow, what you gather every time, and what has to be true before one is finished. The rules you already work to and have never written down.
What you paste is read once and never stored. There is no cache, no account, and no copy kept. Redact the client's name if you like — it changes nothing about the method.
This is the first thing Mycel does
Inside the product the same reading governs every later run: what it found becomes the shape of the next one it drafts, and the “what makes one correct” list becomes the conditions a draft has to satisfy before it may reach a client. Nothing goes out without you.
