Investigate cold cases with an AI partner.
AI-Powered Cold Case Research. Cold Case Investigator gives you the tools published investigators use — evidence-first analysis, pin-and-string boards, AI-assisted research — for your own re-examination of cases that still have questions.
- Browse published cases or import a PDF and let AI extract every person, place, and piece of evidence.
- Ask SOL — your AI investigator — anything about the case. Web-search backed.
- A pin board for your hunches. A scratchpad for half-formed theories. A story canvas for what you find.
- Invite collaborators. Share findings. Publish your story to a public reader.
Free to start. No credit card. Upgrade later for collaboration + heavier AI use.
