Postmine FAQ

How does the AI content generation work?

When you capture a post, Postmine's AI (or your own BYOK model) analyzes the core discussion, key points, and sentiment. It then uses this analysis, combined with your specific Brand Voice profile settings, to generate seven unique pieces of content. Each piece is tailored to the norms and best practices of its target platform, from a detailed blog structure to a snappy Twitter thread with the right pacing.

Can I use my own AI API key?

The $1 trial gives you full access to the Starter plan features for 7 days. This includes generating up to 10 content packs, using the Chrome Extension, setting up Brand Voice profiles, accessing the Content Calendar, and all other core features. If you love it, it automatically converts to a $49/month subscription after the trial unless you cancel, which you can do anytime before the 7 days end with no further charge.

What happens if I exceed my content pack limit?

If you are on a monthly plan like the Starter ($49/mo) and use all your allotted content packs before your billing cycle renews, you will need to upgrade to a higher tier or wait for the next cycle to reset your limit.
