Step 5 Preview is built for professional knowledge work — from large-scale research to structured analysis and interactive reporting.
It coordinates research at scale and turns evidence into finished, auditable deliverables. In one agent action, it coordinated 950 web fetches and assembled 300,000 monthly records across 1,000 locations over 25 years; in another, it produced a 17-sheet analytical workbook with source reconciliation, formulas, and trend models.
Its outputs span technical engineering, creative production, analytical reporting, and public communication.
