Core AI Tools and Their Genealogy Strengths
ChatGPT 5.1 serves as the primary planning and brainstorming engine for genealogical projects. It generates research checklists tailored to specific jurisdictions and time periods, creates timelines from scattered evidence, and suggests record types you might have overlooked. The tool excels at producing structured next-step lists when you're stuck on a research problem.youtubedenyseallen.substack
Claude Sonnet 4.5 specializes in writing and narrative development, transforming dry genealogical facts into compelling biographical narratives while maintaining historical accuracy. Its Artifacts feature creates "living research plans" that you can update iteratively as new evidence emerges. Claude also performs deep document analysis and handles complex evidence evaluation.facebook+1youtube
Google Gemini 3.0 delivers the most accurate handwriting transcription among current AI tools, particularly when used in Thinking mode for challenging historical documents. It also synthesizes complex historical data and resolves lineage discrepancies when combined with NotebookLM.youtubedenyseallen.substackyoutube
Perplexity functions as a cited source locator, finding where specific record types are housed today and providing direct links to repositories and databases. It returns results with inline citations, which supports genealogical proof standards.denyseallen.substackyoutube
The Four-Step Foundation Workflow
Start with ChatGPT to generate a location-specific and time-period-specific record checklist. For example, asking "What records should I search for an 1820s Pennsylvania research problem?" returns suggestions including jurisdiction shifts from parent counties, tax assessment lists, land warrants, quarter sessions court records, early registers, War of 1812 material, and Orphans' Court records.denyseallen.substack
Next, use Perplexity to locate where each record type identified by ChatGPT exists today, complete with repository links and access information. This eliminates hours of manual repository research.denyseallen.substack
Third, transcribe challenging handwritten deeds, wills, or other documents in Gemini 3.0, switching to Thinking mode for particularly difficult script. The transcription accuracy significantly exceeds earlier models.denyseallen.substack
Finally, run your draft biographical paragraph or research summary through Claude for polishing into clear, natural-sounding narrative prose. This four-step sequence addresses the complete research cycle from planning through documentation.denyseallen.substack
