Executive Brief

Business Problem Solved

Reduces the time developers spend writing and understanding code comments by automatically generating high-quality annotations using a language model within VS Code extensions.

Value Drivers

Developer productivity (faster understanding of unfamiliar code)Lower onboarding time for new engineersHigher code quality through better explanations and documentationImproved consistency of comments across a codebase

Strategic Moat

Deep integration into the VS Code extension ecosystem and workflow; leverage of Microsoft’s Language Model API and telemetry for continuous improvement.
