Editor Code Assistant (ECA) - AI pair programming capabilities agnostic of editor
Stars: 356

ECA (Editor Code Assistant) is a free and open-source editor-agnostic tool designed to link Language Model Machines (LLMs) with editors for AI pair programming. It provides a protocol for any editor to integrate, offering a seamless user experience. The tool allows for single configuration across different editors, features a chat interface for collaboration, supports multiple LLM models, and enhances code editing with context details. ECA aims to simplify the integration of LLMs with editors, focusing on improving the user experience and productivity in coding tasks.

- 📄 Editor-agnostic: protocol for any editor to integrate.
- ⚙️ Single configuration: Configure eca making it work the same in any editor via global or local configs.
- ➿ Chat interface: ask questions, review code, work together to code.
- ☕ Agentic: let LLM work as an agent with its native tools and MCPs you can configure.
- 💉 Context: support: giving more details about your code to the LLM, including MCP resources and prompts.
- 🚀 Multi models: Login to OpenAI, Anthropic, Copilot, Ollama local models and many more.
A Free and OpenSource editor-agnostic tool that aims to easily link LLMs <-> Editors, giving the best UX possible for AI pair programming using a well-defined protocol. The server is written in Clojure and heavily inspired by the LSP protocol which is a success case for this kind of integration.
The protocol makes easier for other editors integrate and having a server in the middle helps adding more features quickly, some examples:
- Tool call management
- Multiple LLM interaction
- Telemetry of features usage
- Single way to configure for any editor
- Same UX, easy to onboard people and teams.
With the LLMs models race, the differences between them tend to be irrelevant in the future, but UX on how to edit code or plan changes is something that will exist, ECA helps editors focus on that.
How it works: Editors spawn the server via eca server
and communicate via stdin/stdout, similar to LSPs. Supported editors already download latest server on start and require no extra configuration.
Install the plugin for your editor and ECA server will be downloaded and started automatically:
To use ECA, you need to configure at least one model / provider (tip: Github Copilot offer free models!). See the Models documentation for detailed instructions:
- Type in the chat
/login
. - Chose your provider
- Follow the steps to configure the key or auth for your provider.
Note: For other providers or custom models, see the custom providers documentation.
Once your model is configured, you can start using ECA's chat interface in your editor to ask questions, review code, and work together on your project.
Type /init
to ask ECA to create/update a AGENTS.md file which will help ECA on next iterations have good context about your project standards.

supersonic
SuperSonic is a next-generation BI platform that integrates Chat BI (powered by LLM) and Headless BI (powered by semantic layer) paradigms. This integration ensures that Chat BI has access to the same curated and governed semantic data models as traditional BI. Furthermore, the implementation of both paradigms benefits from the integration: * Chat BI's Text2SQL gets augmented with context-retrieval from semantic models. * Headless BI's query interface gets extended with natural language API. SuperSonic provides a Chat BI interface that empowers users to query data using natural language and visualize the results with suitable charts. To enable such experience, the only thing necessary is to build logical semantic models (definition of metric/dimension/tag, along with their meaning and relationships) through a Headless BI interface. Meanwhile, SuperSonic is designed to be extensible and composable, allowing custom implementations to be added and configured with Java SPI. The integration of Chat BI and Headless BI has the potential to enhance the Text2SQL generation in two dimensions: 1. Incorporate data semantics (such as business terms, column values, etc.) into the prompt, enabling LLM to better understand the semantics and reduce hallucination. 2. Offload the generation of advanced SQL syntax (such as join, formula, etc.) from LLM to the semantic layer to reduce complexity. With these ideas in mind, we develop SuperSonic as a practical reference implementation and use it to power our real-world products. Additionally, to facilitate further development we decide to open source SuperSonic as an extensible framework.
