## What is MedicalFactChecker?

IMPORTANT: You will need an AI provider (for example Anthropic, OpenAI, Deepseek, Mistral ...) API key in order to use this app. See below how to get one.

MedicalFactChecker takes a question or statement, 
For patients / general pubic: 
- Finally understand what the science actually says — not what headlines claim
- Walk into your appointment informed. Walk out actually understanding.
- Ask better questions, get better care
- Understand your diagnosis in plain language — before and after your appointment
- Be an active participant in your own healthcare
- feel free to ask any health question without fearing embarrassment, and use the qualified answer as a discussion base with you doctor

For help care professionals: 
- Save hours of literature review
- be able to give an evidenced based answer to questions your training may not have prepared you for ("I read somewhere nACC will help with my ulcerative colitis ...")
- verify whether some pharmaceutical rep's claims check out against verifiable quality evidence

IMPORTANT: This app requires an AI provider for core functionality. You have to bring your own API key. There are free options (e.g. Mistral AI, cheap (but good!) paid options such as DeepSeek, and more expensive excellent options such as Anthropic's Claude models). How to get an API key is explained here: https://bmlibrarian.org/user-manual/api-keys/
API usage by the medical fact checker may cost from small fractions of a cent to several cents per run. Medical fact checker allows to set budgets.  Even with frequent and extensive testing, the program author has not managed to use up a $5 budget in many months of use.
