Question: Do you know of a tool that can automatically discover good patterns in my codebase and help me reuse them?

If you want a tool that can automatically identify useful patterns in your codebase and help you reuse them, Blueprints is a great option. This open-source AI-assisted coding tool can generate code based on patterns it finds in your codebase, ensuring it's both high-quality and unique. It includes AI-generated code using vector embeddings, pattern capture and reuse directly in the editor, and text editor plugins for Vim, VSCode, IntelliJ Idea, and Sublime Text. By handling lower-level implementation details, Blueprints lets you focus on higher-level abstractions.

Another contender is Crowdbotics, which uses AI to help developers build apps faster and more securely by automating code reuse. It's geared for web and mobile apps written with JavaScript and React Native, but it plans to expand to other languages and frameworks. Crowdbotics is a CodeOps tool that begins with requirements definition to identify reuse opportunities, letting developers focus on differentiating features.

Tabnine is another option. This AI-powered code assistant speeds up and simplifies software development, providing personalized suggestions based on your code and patterns. It supports many programming languages and IDEs, and can be run on-premises or behind a secure SaaS interface. Tabnine is customizable, so you can build your own models trained on your own codebase, making it good for individuals or large teams.

If you want a more general-purpose code intelligence platform, Sourcegraph offers a variety of tools including Cody, Code Search, Batch Changes, and Code Insights. It lets developers search, write and understand large codebases more effectively with features like cross-repository code navigation and fast and accurate code search. Sourcegraph supports multiple programming languages and integrates with popular IDEs, so it's a good option for improving codebase management and productivity.
