Your note, as you typed it
discovery pricing rant. 3 client calls this week, all underpriced discovery then fought scope creep for months. thinking = cheap, doing = expensive... backwards?? the $ of an engagement is set in the first 2 weeks. also that story about the agency that "did discovery already"
Your draft, in your voice
Quality 87 · sounds like youWhy consultants undercharge for discovery work
Most consultants price discovery like an afterthought. It's the first thing a client buys from you, and it's the piece of work that shapes everything downstream, yet it's routinely handed over at a discount, or worse, free.
Here's what I've noticed across three client calls this week: underpricing discovery teaches the client that thinking is cheap and doing is expensive. Exactly backwards…
Real output shape. Every claim traces back to the note and the writer's knowledge base.
How it works
Drop in your thinking
Paste notes, client-call stories, blog posts, anything that shows how you think and write.
PubCasa learns your voice
Sentence rhythm, vocabulary, signature phrases. The voice on the page is yours, not generic AI.
You decide what to publish
Every draft is quality-scored before you see it. You read what's good, refine it, publish under your name.
Why your AI writing tool doesn’t sound like you
ChatGPT and Claude pattern-match across millions of texts, so the output reads as a voice averaged across the internet. Custom instructions reset every conversation and drift in long output. Chapter eight doesn’t sound like chapter one. That’s voice drift, and your readers can tell.
PubCasa is built around a persistent voice profile instead of a prompt. A writer agent drafts in your voice, an editor agent fixes typos without overwriting style, and a quality scorer grades every draft before it reaches you. If a draft doesn’t pass, it goes to a review queue, not your inbox.
Nothing invented, ever. If a claim is not in your knowledge base, it does not appear in your draft. No hallucinated statistics, no fabricated quotes, no invented case studies. And your voice profile is yours: export it as Markdown and leave whenever you want.
Who PubCasa is for
The expert who already writes, not the marketing team with a content calendar. Most of them don’t have a content problem. They have a consistency problem.
Solo consultants
You already write, but client work eats the time. Publish weekly without losing your weekends.
Executive coaches
Your insight is sharper than your output cadence. Earn trust before the discovery call.
Fractional CXOs and advisors
Your audience is technical and skeptical. Generic AI reads as filler to them. PubCasa reads as you.
Experts and indie creators
The system that gets your expertise out of your head and into your byline, week after week.
A fraction of the cost of a human ghostwriter, who charges $5,000+ per article for the same byline.
Frequently asked questions
Can AI really sound like me?
It depends on how much of your writing you give it. With three to five real samples, PubCasa matches 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.
How is this different from ChatGPT or a custom GPT?
Custom instructions are a one-shot prompt that resets every conversation and can't keep your voice consistent across a long document. PubCasa builds a persistent voice profile from your real writing, grounds every draft in your knowledge base, and quality-scores each draft before it reaches you. A writing system, not a smarter prompt.
Does it make things up?
No. Every draft is grounded in your own knowledge base: your samples, notes, and source material. If a claim is not in your knowledge base, it does not appear in the article. No hallucinated statistics, quotes, or case studies.
Will PubCasa train its AI on my writing?
No. Your samples build your voice profile, and your voice profile only generates your drafts. No model training on your content, no sharing across accounts, no selling. Your samples and drafts belong to you.
