DevChat

DevChat is an open-source AI coding assistant delivered as a VSCode plugin, bringing conversational AI directly into the development environment. It supports multiple large language models, including GPT-4 (8k/32k), GPT-3.5, Claude2, and ERNIE Bot, allowing users to switch between them based on task complexity and cost. Core features include conversational code generation, cross-file analysis, 128K long-context understanding, and a Diff View that lets you apply AI-suggested changes with one click—eliminating the need to copy-paste between browser and editor and reducing manual errors. Its precise context management lets you add specific code snippets to the conversation, keeping you in control rather than relying on the AI’s guesswork.

Practical use cases shared by developers show that DevChat can speed up everything from choosing tech stacks, writing business logic, and generating Dockerfiles or Helm charts, to composing commit messages. The plugin also offers an extensible prompt template system, enabling teams to define and reuse custom prompts tailored to their coding standards.

However, there are important caveats.
