Gemini Code Assist
Gemini Code Assist brings Google's Gemini models into the IDEs you already use: inline completions, chat, and newer in-editor agent features.
Individual tier transition (June 2026)
Starting June 18, 2026, Gemini Code Assist IDE extensions and Gemini CLI stop serving individual, Google AI Pro, and Google AI Ultra tiers. Those users migrate to Google Antigravity. Standard and Enterprise subscriptions are not affected. Confirm your tier in Google's deprecation notice.
Editions
| Edition | Who it's for |
|---|---|
| Individual (sunsetting June 2026) | Free / consumer Google accounts → migrate to Antigravity |
| Standard | Teams; IDE extensions + Gemini CLI continue |
| Enterprise | Org-wide; adds code customization from private repos |
Overview: Gemini Code Assist documentation.
Supported IDEs
Install the Gemini Code Assist extension in:
- VS Code
- JetBrains IDEs (IntelliJ, PyCharm, WebStorm, etc.)
- Android Studio
Setup guides: Set up Gemini Code Assist.
Core Features
| Feature | What it does | Best for |
|---|---|---|
| Inline completion | Tab to accept next lines as you type | Boilerplate, repetitive patterns |
| Conversational chat | Ask about open files and project context | Explain code, small refactors |
| Smart actions | Right-click selected code for quick prompts | Unit tests, readability, debug help |
| Finish Changes | Completes in-progress edits from partial diffs | Multi-step refactors without re-prompting |
| Outlines | In-editor summaries interleaved with source | Onboarding to unfamiliar files |
Finish Changes and Outlines are newer agent-style features. Review diffs with the same rigor as any AI agent. See Verifying AI Output.
Effective Use
Help the model with context you control:
- Open related files so chat uses visible editor context
- Select code before asking. "Explain this function" beats "explain the project"
- Be specific in chat:
Write unit tests for UserService.create using Jest. Match existing mock patterns. - Verify against docs. Gemini hallucinates APIs like other models
For Enterprise, configure code customization so suggestions reflect your org's private patterns.
Gemini Code Assist vs Antigravity (Individuals)
If you're on a consumer / individual plan, Google is consolidating tooling into Antigravity, a multi-agent platform with IDE and CLI (agy) successors to Gemini CLI.
| Gemini Code Assist | Antigravity (individual path) | |
|---|---|---|
| Status (June 2026) | Enterprise/Standard continue in IDE | Individual tier migration target |
| Focus | IDE completions + chat | Multi-agent orchestration |
| CLI | Gemini CLI (sunsetting for individuals) | Antigravity CLI |
Check Antigravity documentation for current migration steps. Product names and cutover dates change.
Gemini Code Assist vs Other Tools
| Need | Consider |
|---|---|
| GCP / Android / JetBrains shop | Gemini Code Assist or Enterprise |
| AWS-heavy stack | Amazon Q Developer |
| OpenAI models + Codex agent | OpenAI Codex + OpenAI API |
| AI-native IDE agent | Cursor or Devin Desktop |
| Ship Gemini in your product | Vertex AI / Gemini API (not the IDE plugin) |
For Teams
| Decision | Action |
|---|---|
| Data residency / training | Review Google Cloud terms for Standard vs Enterprise |
| Private codebase patterns | Enterprise code customization |
| Mixed editor fleet | Gemini supports VS Code + JetBrains; Cursor is IDE-specific |
| Policy document | Team AI Policy |
