Augment Code is an AI coding assistant that delivers deep, context-aware support across large codebases. It stands out through advanced context engineering that enables rapid code index updates and fast retrieval, even as code changes frequently. Augment supports models such as Claude Sonnet 4 and 4.5 and GPT-5, integrates with GitHub, Jira and Confluence and supports the Model Context Protocol (MCP) for external tool interoperability. It provides turn-by-turn guidance for complex codebase changes — from refactors and dependency upgrades to schema updates — along with personalized in-line completions that reflect project-specific dependencies. Augment also promotes collaboration by allowing teams to query and share code insights directly within Slack.
