What you get
Import a few pieces you've already published — even ten LinkedIn posts are enough — and Zsper learns your voice and opinions in minutes. Written nothing yet? It interviews you as you write, like a good editor would. Your first draft happens the same sitting.
Long-form thought leadership, how-tos, and explainers that argue a real position — in your English, for your readers.

What changes
Not a new tool to operate — a writing habit that finally holds, because the hard part stops being hard.
The article that used to eat a weekend takes an hour or two — because the thinking is already captured, you only shape and approve.
The calendar suggests what's next and why. A short conversation shapes it. The draft arrives already sounding like you.
Every draft opens already knowing your stances, your customers, your numbers. Say it once, it's yours forever.
What's different
Generic AI tools start every draft from nothing. Zsper first builds a knowledge model of you — and every draft starts from that.

From your knowledge · Zsper
A corner-shop owner two streets from our office taught me more about product-market fit than any pitch deck.
He didn't want our app. He wanted to get paid faster. We moved his billing to a tap-to-pay link — orders doubled in a week. Sometimes the feature is “meet them where they already are.”
Your story · your numbers · your English
And you shape each idea like you would with a good editor — it asks the sharp questions, you supply the thinking, it writes.
How it works
No prompt engineering, no knowledge base to maintain. Zsper works the way a good editor does — it listens first, remembers what you said, and gets sharper with every piece you ship together.
Import your old blogs, newsletters, and LinkedIn posts. Zsper learns your opinions, your stories, your way of talking — and you approve every single thing it thinks it learned.
No blank prompt box staring at you. A short conversation asks what a good editor would ask: who is this for, what do you actually believe, which story from your journey proves it.
Before writing one word, Zsper picks your most-trusted knowledge — the opinions and stories that have earned their place. Then it writes in your English, for your reader.
Keep a paragraph, and Zsper trusts that knowledge more. Cut one, and it backs off. Your tenth piece knows things your first one didn't — and you maintained nothing along the way.

Why you can trust it
New opinions land as proposals, not facts — they can't shape a draft until you confirm them. When something contradicts what it already knows, nothing is overwritten: Zsper shows you both and you decide. And every draft ends with a trace of the knowledge it was built from — receipts, not vibes.
Smart content calendar
Zsper reads your topics, your cadence, and your in-progress drafts, then suggests what to write next and when to publish it. Every suggestion comes with its reason, and every suggestion is one click from a draft.

This week’s plan
Start draftTopic “Merchant payments” has the least coverage — draft the newsletter Thursday. Your in-progress article is slotted first.
Everything included
Every opinion, story, and product fact is stored with a trust score you can see, edit, or delete. Nothing about you is a black box.
Articles, newsletters, and LinkedIn posts drafted from the same knowledge — make the argument once, publish it three ways.
A planner that reads your topics, cadence, and open drafts, suggests what to write next, and tells you why.
Learns your rhythm from your published writing and quietly removes the usual AI tells — banned phrases, uniform openings, tidy summaries. Your English stays your English, down to the spellings and idioms you actually use.
When something new contradicts what it knows, nothing is overwritten. Zsper shows you both, and you decide.
Each piece ends with a real trace of the opinions, stories, and facts it was built from — so you always know what it stands on.

FAQ
A generic AI tool forgets you between sessions and improvises its facts. Zsper keeps a persistent, inspectable knowledge model of your thinking, selects from it before it writes, and shows the provenance of every draft. The prompt is the least interesting part.
Those are template libraries over a model — pick a template, fill in the blanks, get generic output faster. Zsper learns your actual opinions, stories, and voice from what you've published, and builds every draft from that knowledge. Your tenth piece is better than your first. Templates can't do that.
Five to ten published pieces — blogs, newsletters, or LinkedIn posts — are enough for Zsper to learn your voice and core opinions, and importing them takes minutes. Have less? Start anyway: it asks you editor-style questions as you write and learns from every piece you publish. There's no cold-start homework.
Pick an idea (or take the calendar's suggestion), answer a few short questions a good editor would ask — who is this for, what do you believe, which story proves it — and watch the draft write itself from your knowledge. You edit, you publish, it learns. A LinkedIn post takes minutes; an article, an hour or two including your edits.
Yes — and it doesn't guess. Zsper learns your English from what you've actually published: your spellings, your idioms, the currency and units you use, the examples your readers recognise. There's no default locale being applied over the top of you. Wherever you write from, the draft reads like a piece you wrote.
Never. There is no auto-publish. Anything that speaks in your voice — a draft, a learned opinion, a retired belief — waits for your explicit approval.
There isn't one, but here's the honest math. $9 is the founding price for the first 50 seats, locked for life while you stay subscribed. It includes 1,000 AI credits a month — roughly seven full articles plus the newsletters and posts around them. Write more than that and you either add a top-up pack or switch on bring-your-own-key, where your provider bills you directly and we don't charge for the usage at all. Nothing about your account is feature-gated.
Honestly: the first draft is good because it starts from your imported voice and opinions. What changes over a month is depth — every piece you publish teaches it which stories you keep, which stances you soften, which phrases are yours. Your tenth piece draws on things your first one couldn't. And you maintain none of it.
