Metrics + Feedback Loop

A / B / C Three Pillars

From proposal to operations, end to end.

SNS Saku covers all three phases of SNS management: proposal, planning, and daily operations. The AI team handles the groundwork at each phase; humans just approve.

01

A. Deep Research — Proposal Phase

Generate a proposal report in 5 minutes.

The AI Analyst automatically runs industry research, competitor analysis, and customer segment mapping. Dramatically reduces the time account managers spend starting from scratch, and helps improve new client win rates.

02

B. Content Calendar — Planning Phase

Turn calendar meetings into minutes of adjustments.

The AI Strategist automatically designs the monthly publishing plan. Generates a calendar aligned with seasonal context, series themes, and approved brand guidelines with one click.

03

C. AI Studio + Distribution — Daily Operations Phase

Approve, and every SNS moves.

The AI team handles production, review, and distribution end to end. Account managers just see a Telegram notification and approve. Daily operations effort across multiple staff is dramatically reduced.

Built for Japan

Uncompromising on what Japan expects.

Consumer protection laws, anti-stealth-marketing regulations, Japan's approval culture, and LINE support — requirements unique to the Japanese market are built into the platform from the ground up.

Auto-Review for Consumer Protection & Stealth Marketing Rules

Automatically detects risk words during the post generation stage. Flags expressions that may violate consumer protection laws or imply undisclosed advertising, and suggests alternatives. Integration with the approval workflow prevents problematic posts from going live.

LINE Support & Japan-First SNS

Supports content generation and distribution optimized for Japan's major social platforms, including LINE Official Account posts. Platform-specific character limits and media restrictions are automatically applied.

Brand Kit Seasonal Awareness & Japanese Calendar Support

Set visual and copy tone for Japanese seasonal events — New Year, Golden Week, summer festivals, year-end — in Brand Kit. Delivers consistent, on-brand messaging throughout the year.

Approval Logging & Compliance-Ready Flow

Every approval is recorded — who, when, and which post. Approval logs suited to Japan's internal sign-off culture and compliance requirements are retained in Firestore and can be reviewed or exported at any time.
