Lucent Code: AI That Reads Your Code Like Your IDE Does
Most AI coding tools work by searching your files. They glob for relevant-looking paths, grep for the symbol name, and hope the context window fits. It works surprisingly often — until it doesn’t, and the AI confidently suggests a change that breaks three things it couldn’t see.
Lucent Code takes a different approach: it reads your code the same way VS Code does, through the language server.
LSP-First Intelligence
When you ask Lucent Code about a symbol, it doesn’t grep your files. It calls executeDefinitionProvider, executeHoverProvider, and executeReferenceProvider — the same APIs your editor uses for go-to-definition and find-all-references. The result is accurate type information, resolved references, and live diagnostics, not pattern-matched guesses.
| Grep-based tools | Lucent Code | |
|---|---|---|
| Symbol resolution | Regex | executeDefinitionProvider |
| Type info | Guessed | executeHoverProvider |
| References | File scan | executeReferenceProvider |
| Diagnostics | None | Live from language server |
Any Model, Any Provider
Lucent Code supports three provider backends out of the box:
- OpenRouter — 500+ models including Claude, GPT-4o, Gemini, Mistral, Llama. Free tier available.
- Anthropic — native Claude access without a proxy hop.
- NVIDIA NIM — direct GPU inference for Nemotron and other NVIDIA models.
Switch providers in one click from the model selector in the status bar.
What Else Is In There
- Streaming chat panel — markdown rendering, syntax-highlighted code, copy/insert buttons
- Inline completions — ghost-text suggestions, auto or manual (
Alt+\) - Slash-command skills —
/code-review,/refactor,/debugging,/tests,/commit, and more. Load your own from GitHub or npm. - AI editor tools — rename symbols, insert code, apply quick fixes — with an approval card for destructive operations
- Git worktrees — isolate AI sessions so your main workspace stays clean
- MCP support — connect external tools via Model Context Protocol
Getting Started
Install from the VS Code Marketplace. Add an API key for your preferred provider and you’re running in under two minutes.
