Fact-checking Progress:

- [ ] Step 2: Search authoritative sources
- [ ] Step 3: Compare claims against sources
- [ ] Step 4: Generate correction report

Step 1: Identify factual claims
Scan the document for verifiable statements:
Target claim types:
- Technical specifications (context windows, pricing, features)
- Version numbers and release dates
- Statistical data and metrics
- API capabilities and limitations
- Benchmark scores and performance data
Skip subjective content:
- Opinions and recommendations
- Explanatory prose
- Tutorial instructions
- Architectural discussions
Step 2: Search authoritative sources
For each claim, search official sources:
AI models:
- Official announcement pages (anthropic.com/news, openai.com/index, blog.google)
- API documentation (platform.claude.com/docs, platform.openai.com/docs)
- Developer guides and release notes
Technical libraries:
- Official documentation sites
- GitHub repositories (releases, README)
- Package registries (npm, PyPI, crates.io)
General claims:
- Academic papers and research
- Government statistics
- Industry standards bodies
Search strategy:
- Use the exact claim subject + specification + provider
- Include current year for recent information
- Verify from multiple sources when possible
Step 3: Compare claims against sources
Create a comparison table:
| Claim in Document | Source Information | Status |
|---|
