Sweep AI

Sweep AISince 2023-07

Sweep AI is an autonomous AI coding agent designed to act as an automated junior developer for your engineering team. When an issue is created or a bug is reported in your GitHub repository, Sweep reads the codebase, plans the necessary file changes, writes code, and opens a fully tested pull request. Sweep handles small bugs, repetitive feature requests, refactors, and test coverage expansions, freeing human engineers to focus on high-level architecture.

Sweep uses vector embeddings over your repository's files combined with frontier LLM reasoning loops. It runs linters, type checks, and automated test commands inside sandbox runners to iteratively debug its own code until all CI checks pass. Developers can interact with Sweep directly in GitHub PR review comments to request adjustments, and Sweep will update the diff automatically.

Factory AI creates autonomous 'Droids'—specialized AI agents designed to automate the repetitive tasks across the software development lifecycle. From generating comprehensive unit test suites to reviewing pull requests, resolving security vulnerabilities, and migrating legacy codebases, Factory Droids operate seamlessly within your existing Git and CI/CD pipelines. Built for engineering organizations seeking to amplify developer productivity, Factory integrates directly with Jira, Slack, GitHub, and cloud providers to handle end-to-end engineering tickets.

Factory's Droids are orchestrated using a multi-agent framework that combines static analysis, dynamic AST parsing, and frontier reasoning models. Each Droid is specialized for a distinct engineering task, such as Code Review Droid, Test Generation Droid, or Migration Droid. They run safely within sandboxed execution environments, adhering to company security policies and compliance standards while delivering verified, actionable code diffs.
