Smart Stack is an AI-powered documentation assistant built for software developers. It lets developers select the technologies in their stack and ask questions that are answered using the latest official documentation rather than outdated model knowledge. The platform indexes documentation for 200+ technologies, including React, Next.js, Hono, Tailwind, Python, Go, PostgreSQL, Redis, and more. Smart Stack keeps documentation current by monitoring releases and automatically re-indexing sources. Its AI can understand multiple technologies together, making it useful for questions involving how different tools integrate. It also includes web search for GitHub issues, Stack Overflow, release notes, and other sources, plus an integrated documentation reader and source citations for verifying answers.
