Reduce AI usage and touch your code inside the browser.

Ceres brings the browser assistant into the IDE, shortens the path between browsing and coding, and helps reduce token usage with more focused context. You move faster between page work, code edits, and AI help without stretching the workflow across extra tools.

Less context. Better code search. Safer AI edits.

Search your codebase, send less to the model, and review changes before you apply them.

Search and collect context faster

Use codebase search with on-device AI and focused context collection - feed your agent only what it matters

Edit code with focused AI help

Work on the exact file, block, or component you want to change and keep chat, edits, and code decisions close to the editor.

Apply changes with control

Review the diff first, apply only what you want, and keep risky edits from turning into cleanup work later.

Ceres helps reduce the cost of the agent setup above instead of feeling like a separate extra tool.

Codebase Search

Search your codebase locally with AI before you send anything to an agent.

1. Search locally first

Search with local AI

Use local AI on your computer to search your codebase without sending your whole project to a model first.

2. Find the exact context

Narrow the result first

Find the right file, block, or reference before you ask the agent to do the task.

3. Send less to the model

Keep search local

Use on-device search to reduce noise, keep control, and pass only the useful result into your workflow.

Controlled AI Tasks

Connect your favorite LLM and let it execute focused tasks instead of wasting tokens on easy setup work.

4. Bring your own LLM

Bring your own LLM

Connect the model or agent you prefer with an OpenAI-compatible key - now full support for Codex and Claude Code.

5. Give ready context

Start with useful context

Ceres gives the useful file, block, output, or result directly to the AI, so it does not waste time searching first.

6. Reduce AI usage

Spend fewer tokens

Connect codebase search to your agent and spend less on source searching. Codebase search is powered by on-device AI, then the agent can execute the task with one less step.

Live CSS Editing

Edit CSS live from the browser and save changes directly into your files, with automatic page mapping based on the platform you use.

7. Edit CSS live

Change CSS in the browser

Right-click in the browser, edit the CSS, and see the result instantly on the page.

8. Save to your files

Save while you preview

The change appears live in the browser and is saved at the same time into the correct file in your project.

9. Open the right file

Jump straight into the IDE

Open the exact file you are viewing directly in the correct IDE tab, with automatic mapping and no manual config files.

Works with your favorite agent

Keep Ceres next to the coding agent you already use instead of rebuilding the same workflow from scratch.
