The company's truth,to whoever needs itin their own language.

Platty does not produce piles of documents.

acts as the interpreter.

The SSOT takes each role's question in that person's own words and

It answers with the truth in the code.

01Conversations by role — the same SSOT, four languages

A customer asked why their points expired. What's the expiration rule?

PLATTY

Points are erased by a midnight batch job 365 days after they are earned. A notice goes out 7 days before deletion. Points granted manually by an administrator follow the same rule.

  • Point ledger expiration scheduler
  • Business rule §Points 4.1

Product managers

What happens to my diaries and order data if I close my account?

PLATTY

Accounts are anonymized rather than deleted. Diaries are switched to private. Order and settlement data is retained for the legally required period. You should check that your privacy notice reflects the fact that this isn't a full deletion.

  • Account anonymization flow
  • Data dictionary §Members
  • Unverified · legal basis document for the retention period constant

Developers

If we switch the PG provider in the payment module, how far does the impact reach?

PLATTY

The impact spans 4 areas across 3 repositories — payment creation, cancellation, settlement deduction, and webhook intake. The settlement batch job in particular reads the PG fee field directly. Changing the interface alone won't finish the job.

  • Graph trace: 12 paths from payment → settlement
  • Spec impact analysis result

AI coding agents · MCP

gather_context: "Revise review reward payout logic"

PLATTY

It returns 2 related epics, 5 business rules, 17 target symbols, recent change history, and the forbidden boundaries (the lock that prevents duplicate payouts). The agent understands the whole structure before it starts editing.

  • MCP context bundle — the same SSOT people use

02What gets built inside — the structure of the SSOT

These are not documents for people to read. They exist so AI can answer any question with evidence, A machine-readable encyclopedia of the company's truth, organized layer by layer.

Product managers

마감이 하루 늦어져서요. 정산 배치 2시로 당겨주세요.

03:00은 그냥 정해진 시각이 아닙니다.

MEMORY · 확정

카드사 매핑 파일이 02:40에 도착한다. 그 전에 돌리면 정산이 비어서 나간다

2022년 사고 이후 고정 · 정산팀 확인

2시로 당기면 같은 사고가 납니다.

Product managers

아, 그래서 3시였구나.

물어볼 사람 못 찾아서 일정을 2시로 앞당겼으면, 이번 달 정산이 틀어졌습니다.

Ask & confirm

Usage is input

When someone talking with AI produces knowledge worth keeping, they just say "add that to Platty." That knowledge goes straight into memory.

Trust level

Only the verified is promoted

Memory starts out as a suggestion. It only gains a higher trust level after review. Rumor never passes for truth.

Result

Tacit knowledge as an asset

Knowledge that used to leave with an employee stays in the company's SSOT. The longer you use it, the less reason there is to switch.

04Where you use it — Touchpoints

Platty is delivered over MCP. We did not build a separate app — connect Platty to the AI your people already use, and that AI starts to understand your company.

SSOT

01

to the people doing the work

Connect it to the AI app you already use, like Claude or ChatGPT. Ask about your company right there.

02

to developer tools

Coding agents like Claude Code and Cursor call the SSOT as a tool.

03

to in-house AI

Agents and chatbots your company built connect through the same MCP standard.
