Pros & cons
Advantages
- Completely free to use, with no premium tier or hidden costs
- Built by an established, independent fact-checking organisation with strong editorial standards
- Open-source code allows customisation and integration into other tools
- Focuses on catching recurring misinformation rather than one-off false claims
Limitations
- Coverage limited to claims previously fact-checked by Full Fact, so emerging or novel false claims may not be flagged
- Requires technical knowledge to implement the open-source version effectively
- Primarily trained on UK-focused content and may be less effective for international claims
Use cases
Newsrooms checking whether claims in stories have been previously debunked
Researchers studying patterns of misinformation and how false claims spread
Social media platforms or content moderation teams flagging repeated false claims
