Frequently asked questions

PubCasa learns how you write from your existing content, then turns your notes, stories, and rough ideas into polished drafts in your voice. Articles, essays, newsletters, LinkedIn posts, book chapters. The thinking is yours. The voice is yours. PubCasa handles the production.

ChatGPT and Claude are single-call tools. You ask, the model answers in one shot. PubCasa is a multi-agent system, which means several specialized AI workers handle different parts of the job. A writer agent drafts the piece in your voice. An editor agent preserves voice while fixing typos. A quality scoring agent grades the output before it reaches you. Drafts that do not pass go to a review queue. You do not waste time reading bad output, and the AI never invents facts that were not in your knowledge base.

Custom instructions are a one-shot prompt that resets every conversation. They do not learn from your past writing, they do not catch hallucinations, and they cannot keep your voice consistent across a long document. PubCasa builds a persistent voice profile from your real writing samples, grounds every draft in your knowledge base so the AI cannot invent facts, and runs each draft through a quality scoring step before it reaches you. It is closer to having a writing system than a smarter prompt.

Three to five real samples is the minimum. More is better. The system reads your sentence rhythm, vocabulary, signature phrases, and punctuation habits, then matches them when drafting. With five strong samples, most users find the drafts read as theirs after a light edit. With ten or more, the match gets noticeably tighter and stays consistent across long documents, with no voice drift between chapter one and chapter eight.

You paste or upload three to five samples of your existing writing. PubCasa analyzes your sentence structure, vocabulary, tone, and punctuation habits, then matches that style when generating new drafts. Voice match improves as you add more samples.

It depends on how much of your writing you give it. With three to five real samples, PubCasa can match the rhythm, signature phrases, and tone of your writing well enough that readers recognize it as yours. The more you feed it, the closer the match gets.

Generic AI tools pattern-match across millions of texts, so the output reads as a voice averaged across the internet. Many readers can spot that. PubCasa learns your specific patterns: your sentence rhythm, your vocabulary, the way you actually structure an argument. So the output reads as yours, not as generic AI. The honest answer is: it depends on how much of your writing you give it. With enough samples, your readers do not notice. With too few, they might.

No. PubCasa never invents facts. Every draft is grounded in your own knowledge base: the writing samples, notes, brain dumps, and source material you give the system. If a claim is not in your knowledge base, it does not appear in the article. The AI cannot insert a statistic, an example, or a story you did not provide. This is the brand integrity guarantee that separates PubCasa from a generic large language model.

PubCasa was built for long-form thought leadership and short-form social. LinkedIn posts, Substack newsletters, blog articles, personal essays, book chapters, client memos, podcast scripts, and show notes. The same voice profile powers all of them, so a LinkedIn post and a chapter from the same writer sound consistent. New format support is added based on what early-access users actually publish.

No. Your writing samples are used only to build your voice profile, and your voice profile is only used to generate your drafts. PubCasa does not train models on your content, does not share it with other accounts, and does not sell it. Your samples and drafts belong to you. See the privacy policy for the full data handling details.

PubCasa is for solo consultants, executive coaches, fractional CXOs, and subject-matter experts who already write but cannot keep up the pace. Most of them do not have a content problem. They have a consistency problem. PubCasa does not create ideas. It publishes yours.

PubCasa is in early access while we work with our first users on three things: voice match, keeping the AI honest about facts, and sharper quality scoring.
