Moving Beyond Expertise

Toss's Technical Writer(TW) role is expanding beyond simple documentation writing to become a Product Owner who determines the direction of the product and builds it directly. They design products based on their expertise in why documents are hard to read and what structures are good for AI to utilize.

Toss launched the in-house documentation platform 'todoc' to solve the limitations of existing documentation tools: the high barrier to entry for non-developers, the accumulation of 'garbage knowledge', and knowledge fragmentation across tools. Within six months of launch, todoc has secured over 500 documents and over 40,000 valid pages, with more than 1,000 users every month.

todoc's 4 core values are as follows:

• Accessibility: Providing an environment where anyone can easily write and edit documents
• AI-friendliness: A structure that allows AI to easily utilize knowledge through APIs, CLI, MCP, etc.
• Single Source of Truth (SSoT): Gathering scattered knowledge in one place to keep information up to date
• Scalability: The ability to start documenting immediately on the platform regardless of the organization's size

The future challenge is maintaining the quality of documents. To reduce the effort users spend writing documents themselves, todoc aims to build a system where knowledge updates itself, by automatically documenting messenger conversations, code changes, and decision-making processes, and having AI detect outdated documents and suggest improvements.
