Lite coding assistant for VS Code

In case of heavy agents that eat up computer memory and use tokens, Ceres takes a different approach: a lite coding assistant powered by your favorite LLM that just works.

Predictable AI help

Don't want to wait for your AI agent to explore your entire repository just to change the next blocks? Ceres can do that because it interacts directly with the VS Code or JetBrains editor!

Smart context, total control

⚖ïļ

Use Navigation Mode to automatically find relevant workspace files, or turn it off to strictly use the blocks and files you manually select.

Speak to your code

Use your voice to refactor functions and apply changes.

Voice Prompting

🎙ïļ

Speak naturally and request the necessary changes instead of writing.

Apply changes mode

See exactly what will change before anything is written to your project.

Apply changes when you need

⚡

Apply changes without copy and paste directly to the source base - review before you approve!

JetBrains IDEs JetBrains

Keep Ceres open in Chrome and your IDE at the same time. Your conversation and current draft update automatically, so you can move between the browser and your code without starting over.

Research in Chrome, code in your IDE

🌐

Use the browser to explore pages and collect useful information, then continue the same conversation beside your project in Visual Studio Code or a JetBrains IDE.

Live synchronization requires the browser extension to have access to the same local project folder. Available with Visual Studio Code and supported JetBrains IDEs.

A light, budget-friendly coding assistant for your favorite IDE.

Fix issues and grow your project with your rules without keeping agents running in the background.
