Introduction
Gemini Coder lets you conveniently copy folders and files for chatbots. With the Connector browser extension you can initalize them hands-free!
The extension uses the same context for built-in API features: Fill-In-the-Middle (FIM) completions and file refactoring. Hit apply changes to integrate AI responses with just a single click.

- Versitale: Not limited to Gemini or AI Studio
- Private: Does not collect any usage data
- Local: Talks with the web browser via WebSockets
- One of a kind: Lets you use any website for context
- Lightweight: Unpacked build is just ~1MB

You own the context
Other AI coding tools try to "guess" what context matters, often getting it wrong. Gemini Coder works differently:
- You select which folders and files provide relevant context
- You control what examples of coding conventions to include
- You know how much tokens is used in web chats and FIM/refactoring requests
The result? Unmatched in accuracy, speed and cost AI assistance.
Too many tokens fighting for attention may decrease performance due to being too "distracting", diffusing attention too broadly and decreasing a signal to noise ratio in the features. ~Andrej Karpathy
