LexAI for VS Code / Cursor

Part of the LexAI monorepo (packages/vscode). Twin of the Chrome extension and CLI Prompt Builder.

Bring your own LLM key. LexAI helps you write and work with code in VS Code / Cursor — no LexAI account, no subscription, no LexAI servers.

Select text or code → run an action or ask in Code Assist → Accept / Regenerate / Discard in the editor.

Also available for Chrome

Use the same LexAI writing assistant on any webpage:

LexAI — AI Writing Assistant (Chrome Web Store)

On the web: select text → Fix / Rephrase / Shorten / Expand / Explain / Make Prompt → Replace or Copy. Same BYO-key idea as this VS Code extension.

All features (VS Code / Cursor)

Code Assist (workspace-aware)

  • Select code → Code Assist → type what you want in an inline prompt above the selection (Copilot-style zone), then Ask LexAI.
  • Examples: explain, refactor, add error handling, rewrite for clarity, review a function.
  • LexAI gathers workspace context: selected code, surrounding lines, import/require targets, and symbol definitions from other files (via the language server).
  • Result opens in the suggestion zone with Accept / Regenerate / Discard.
  • Available from CodeLens, editor context menu, Command Palette, and the Activity Bar sidebar.

Writing actions

Action What it does
Fix Grammar Correct spelling, grammar, and punctuation
Rephrase Make text clearer / more professional
Shorten Cut fluff while keeping the message
Expand Add detail, context, and supporting points
Explain Break down complex text into plain language
Make Prompt Turn a rough idea into a structured AI prompt

Prompt Builder (Make Prompt)

  • Structural patterns (auto, zero-shot, role, few-shot, and more)
  • Persona presets, including custom persona text
  • Preferred output format
  • Optional model override for Make Prompt only
  • Adjust in Settings, or via inline option chips in the suggestion zone (click a chip to regenerate)

Writing styles

Apply to Fix / Rephrase / Shorten / Expand / Explain:

Default · Formal · Casual · Academic · Creative · Concise

Change in Settings or via option chips in the suggestion zone.

Where you can start an action

  • CodeLens — select ≥10 characters; click LexAI on the first selected line to expand actions in place (Code Assist + writing actions)
  • Editor context menu — right-click selection → LexAI submenu
  • Gutter / line-number context — LexAI submenu when a selection is active
  • Command Palette — LexAI: Fix Grammar, Rephrase, Shorten, Expand, Explain, Make Prompt, Code Assist, Show Actions, …
  • Activity Bar sidebar — LexAI icon → Workspace panel: paste or type text, pick an action (including Code Assist), run, Copy or reuse as input; Insert selection pulls from the editor
  • Status bar — ✓ LexAI ready · ⟳ LexAI processing · ⚠ LexAI not ready (click opens Settings)

Suggestion UI

  • In-editor zone (default) — comment widget above the selection with Accept / Regenerate / Discard and option chips
  • Side panel — optional suggestion panel
  • Setting lexai.suggestionUi: zone | panel | both
  • lexai.previewBeforeReplace — preview before replacing the selection (default on)
  • lexai.askOptionsBeforeGenerate — optional Quick Picks for style / Prompt Builder before each run

Settings & account-free setup

  • LexAI: Open Settings — branded settings UI for provider, model, writing style, Prompt Builder, and API key
  • LexAI: Set API Key / Clear API Key
  • LexAI: Show Configuration Status
  • Providers: OpenAI · Anthropic · Groq · OpenRouter
  • API key stored in VS Code Secret Storage (not plain settings)
  • Non-secret prefs use lexai.* settings

Quick start

  1. Install from the VS Code Marketplace, or Install from VSIX.
  2. Command Palette → LexAI: Open Settings → provider, model, API key.
  3. Select text or code → click LexAI on the line → pick an action or Code Assist.
  4. Review in the suggestion zone → Accept to replace the selection (or Copy from the sidebar / panel).

Install / publish details: DEPLOY.md.

Privacy

  • No LexAI backend and no LexAI telemetry.
  • API key lives in the editor’s Secret Storage.
  • Your text is sent only to the LLM provider you configure.
