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?
Absolutely! Postmine offers full BYOK (Bring Your Own Key) support. You can integrate your own API keys from major providers like OpenAI (GPT), Anthropic (Claude), Google (Gemini), or DeepSeek. This gives you complete control over the AI model used and directly manages your costs through your existing provider account, while still leveraging Postmine's powerful formatting and workflow.
What is included in the $1 trial?
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. For the 10-Day Pass, you get 50 packs to use within the 10-day window. The system will notify you as you approach your limit so you can plan accordingly.
