Scott AI is the planning layer for engineering teams that build with coding agents. It provides an agentic workspace for software spec design where multi-agent swarms are given secure, one-click access to a full codebase to explore design paths in parallel and debate architecture decisions. Scott then surfaces key divergences and lets builders choose the best options so teams align on specifications before agents start executing. Scott AI was founded in 2025 and is part of Y Combinator's Fall 2025 batch.
