Prosie is free to use. You may write as much as you want in your own hand at no charge.
You must supply your own API keys from Anthropic, OpenAI, or OpenRouter.ai.
You are responsible for monitoring your token usage. Your chosen provider may charge you, and you are solely responsible for any fees incurred.
We provide estimates of token usage and costs based on the context your prompts use. These estimates are approximate and may not be accurate. We recommend reviewing your usage regularly in your LLM provider dashboard and adjusting your usage as needed.
If you generate profanity or NSFW content, it is your responsibility to ensure your chosen LLM model supports it.
Your API keys are stored encrypted at rest and can be deleted at any time. We strongly recommend setting a token limit in your LLM provider of choice to prevent accidental overuse.
Prosie is currently beta software. You use it at your own risk.
