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 can claim daily bonus Coal by visiting the app. Unclaimed daily Coal expires after 24 hours. This applies to all plans.
Does Coal roll over?
Free tier: Coal does not roll over between months. Pro & Team: Unused Coal rolls over up to your max balance cap.
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.
Subscription
How do I subscribe to Pro?
Sign in to PromptAnvil and click "Upgrade to Pro" above. Payments are handled securely through LemonSqueezy. You can choose monthly or annual billing.
Can I cancel anytime?
Yes! Cancel from your Profile page anytime. Your Pro features remain active until the end of your billing period. No questions asked.
Will pricing change?
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 save configs to the cloud (3 for free, unlimited for Pro). Clearing browser data may remove locally saved configs, but cloud-saved configs are always accessible.
API & Integrations
Is there an API?
Yes! PromptAnvil has a public API for pack-based prompt generation. Every plan includes a free daily quota (Free: 25 req/day, Pro: 200 req/day, Team: 1,000 req/day). After the quota, each request costs 2 Coal. Integrate with ComfyUI, Automatic1111, InvokeAI, or any tool via simple REST calls.
How do I get an API key?
Sign in and visit your Profile page to create API keys. You can have up to 5 active keys. Each key starts with "pa_" and is shown only once upon creation — make sure to copy it.
