~/the problem
Solo founders aren't lazy.
Content is just expensive.
→ content gets cut by week 3
→ building loses momentum by month 2
→ you quit
Content overhead doesn't kill bad founders.
It kills good ones.
~/how it works
One brief in.
Four posts out.

AI reads your input + visual context. Generates platform-tuned content in parallel. Under 30 seconds.
