Common Questions
About Coal
What is Coal?
Coal is our credit system for AI-powered features. Just like coal fuels a forge, Coal fuels your AI operations in PromptAnvil. Non-AI features like batch generation, config creation, and exports are always free and unlimited.
How does Daily Coal work?
Everyone gets base Coal at the start of each month. On top of that, you earn daily bonus Coal. Free users must claim their daily Coal by visiting the app (expires in 24h). Pro and Team users get daily Coal auto-credited.
Does Coal roll over?
Free tier: Base Coal resets monthly, unclaimed daily Coal expires. Pro & Team: Unused Coal rolls over (up to 1 month's worth max).
What happens if I run out of Coal?
You can still use all non-AI features (batch generation, config editing, exports). AI features will be unavailable until your Coal resets next month or you upgrade your plan.
Will pricing change after beta?
We plan to keep a generous free tier. Pro pricing may adjust based on AI costs, but early supporters will be grandfathered into their original rates.
Where are my configs stored?
Configs are stored locally in your browser by default (no account required). If you sign in, you can also save and sync configs to the cloud for free. Clearing browser data may remove locally saved configs, but cloud-saved configs are always accessible.
API & Integrations (Planned)
Is there an API?
Full API Access is planned for the Pro tier but is not yet available. We're designing endpoints for batch prompt generation, config analysis, and integrations with tools like n8n or Zapier. Stay tuned for updates.
How will I get an API key?
When the API launches, Pro users will be able to generate API keys from their profile page. If you have a specific use case during beta, feel free to contact us.
