The problem

Staying relevant is a
full-time job.

You have genuine expertise. The internet produces infinite noise. Between them stands the daily grind of reading, filtering, and turning it into something worth saying.

Before Quillby
  • 45 minutes scanning feeds, newsletters, and Twitter to find one thing worth writing about.
  • Blank page paralysis. You know your subject. You don't know where to start.
  • Generic AI output. You try ChatGPT and it sounds like a LinkedIn HR bot.
  • Posting irregularly because "finding something to say" isn't part of your actual job.
With Quillby
  • Ask Claude "what should I post today?" and get a ranked brief of what's actually relevant.
  • One-shot drafts sourced from real articles, structured as your kind of post.
  • Sounds like you — not a template. Quillby learns your voice from examples you approve.
  • Publish consistently without adding a single new tool, tab, or workflow to your day.
