FAQ

Common questions

QIs the output actually good?

Yes. The system prompt is trained on the top 100 BIP founders on Twitter/X. It knows what hooks land, what formats work, and how real indie founders talk.

QWhat platforms does it support?

Twitter/X threads, single tweets, and LinkedIn posts. Each is optimized differently — thread character limits, LinkedIn front-loaded hooks, the works.

QHow is this different from ChatGPT?

ChatGPT gives generic advice. FoundrPost knows BIP culture, specific formats, and what works for indie founders. It never says "Excited to announce."

QWhat happens when I hit my limit?

Free plan: 3 posts/month. Starter ($9/mo): 30 posts. Pro ($19/mo): 100 posts. Upgrade anytime from your dashboard.

QCan I cancel anytime?

Yes. No contracts, no gotchas. Cancel from your settings and keep access until the end of your billing period.
