Overview

Generalist AI writing is commoditized to near zero; this isn't — it's writing inside a narrow technical domain (fintech, medical devices, industrial B2B) where AI accelerates research and drafting but can't substitute for actually understanding the terminology and being able to add a genuine insight the model couldn't produce. Priced per article or on retainer, aimed at technical and B2B publications that need writers who won't sound like an outsider.

Why it works

Generalist AI writing is commoditized; writing inside a narrow technical domain where AI accelerates research but can't substitute for real domain fluency isn't. The evidence for this hustle consistently points to selling outcomes and personally editing AI output, not just producing more words faster.

How it makes money

Per deliverable + retainer

How to start

  1. Choose a narrow industry (fintech, medical devices, industrial B2B) where generalist writers can't compete.
  2. Learn the terminology well enough to write without sounding like an outsider.
  3. Make five samples in that specific domain, not generic business writing.
  4. Build a focused profile and portfolio that only shows work in this specialty.
  5. Contact prospects who need domain-specific content — trade publications, specialist B2B companies.
  6. Sell a paid trial article before pitching an ongoing arrangement.
  7. Research and draft with Perplexity, ChatGPT or Claude as an accelerant, not a replacement for domain knowledge.
  8. Fact-check every technical claim against a credible source in the field.
  9. Add genuine insight or a specific example the AI draft couldn't have produced alone.
  10. Retain the client on a per-article or monthly arrangement once trust is built.
