Product · Idea → draft
No blank prompt box. Zsper works like a good editor: it asks the sharp questions, picks your most-trusted knowledge, and writes while you watch.
The flow
Who is this for? What do you actually believe? Which story from your journey proves it? A short conversation shapes the piece before a single word is drafted.
The structure is yours to reorder, cut, or push back on — the draft only starts on your yes.
Sections stream in live, in your voice, built from your knowledge. No four-minute spinner, no black box.
Change your stance mid-flow, swap the story, tighten the angle — it re-plans instead of arguing.
How a draft gets built
deterministic · LLM-freeKnowledge
Your records — stories, stances, facts
Understanding
Confidence computed from evidence
Reasoning
Conflicts resolved, losers suppressed
Context
The brief assembled — relevance × trust

the only callIt only phrases the brief — never picks your ideas
Grounded & yours
Every piece ends with a real trace of the opinions, stories, and facts it was built from. You always know what a draft stands on — and shipping it teaches the brain.
No made-up stats, names, dates, or quotes. If it isn't in your knowledge, it isn't in your draft.
Keep a paragraph and the knowledge behind it earns trust; cut one and it backs off. The tenth draft knows things the first couldn't.
There is no auto-publish. Nothing goes out in your voice without your explicit yes.

FAQ
A LinkedIn post takes minutes. A full article lands in under a couple of minutes of drafting time — the hour is yours: shaping the idea, reviewing the outline, and making your edits.
At every stage. Push back in the conversation, edit the outline, rewrite any section, or throw the draft away — rejections teach it just like edits do.
No. Drafts are grounded in your knowledge by rule: it will not invent a number, a customer, or a quote. When it needs a specific you haven't given, it asks instead of guessing.
The learning loop runs: what survived your edits gains trust, what you cut loses it, and new stances you wrote get proposed to the brain for your review.
