About Saturn

Saturn integrates EDINET filings, gBizINFO, and corporate registries into a single spreadsheet UI. Define columns, and AI handles the rest — company research in 30 sec, invoice transfer from 8 hours to 5 min, resume screening at 100/day. Works via UI, API, and MCP (22 tools for AI agents).
