If you're looking for a plugin to automatically generate commit messages within your IDE, AICommit is a great option. This plugin works with JetBrains IDEs and uses OpenAI GPT to boost coding productivity. It offers features like automatic commit message generation, code explanation, code translation, code optimization and documentation generation. That can be a big help when it comes to documenting code changes, and it can make your development life easier.
Another option is CodiumAI, which works with IDEs and Git tools to boost coding with test generation, code reviews and behavior coverage. It's more geared toward testing and code reviews, but if you're already using it for those tasks, its IDE integration could help you in other ways. The tool's PR-Agent feature can also auto-describe pull requests, which can help speed up the review process.
If you're looking for a more general purpose AI-powered coding assistant, Tabnine is worth a look. It offers a lot of features, including code generation, task automation and AI chat support. Tabnine supports many programming languages and IDEs, and it keeps your code private and secure. It's not specifically geared toward commit message generation, but its broader abilities can still help you.
