01
Designed for follow-up
3Stone preserves attachment context for supported follow-ups so the same file does not need to be parsed again for every question.
02
Review important work
AI can miss details in complex scans, charts or ambiguous source material. Verify legal, medical, financial and other high-impact conclusions against the original file.
