Chat Wizard is a VS Code extension that lets you search, analyze, and manage AI chat history from tools like GitHub Copilot, Claude, Cursor, Cline, Windsurf, Continue.dev, Amazon Q Developer, Gemini Code Assist, and more.
It acts as a unified AI coding assistant memory and analytics layer for developers — your conversation history is no longer trapped inside whichever tool or IDE created it. Inspired by bAInder.

- Your history travels with you. Switch from Cursor to VS Code, try Windsurf for a project, add Cline to your workflow — your full conversation archive stays intact and searchable in one place. No more context lost when you change tools or IDEs.
- Everything in one view. Whether you use one AI coding tool or five, Chat Wizard aggregates sessions from all of them. Search across a year of Copilot, Claude, Cline, Cursor, Windsurf, Aider, Google Antigravity, Continue.dev, Amazon Q Developer, and Gemini Code Assist conversations in a single query.
- 100% local, read-only, zero setup. Chat Wizard never makes a network call, never modifies your session files, and requires no API key or account. It passively reads what your existing tools already write to disk.
- Not just a viewer. Full-text search with regex, a deduplicated prompt library, a code block archive, per-model usage analytics, and a timeline with activity heat maps — capabilities that no individual AI tool exposes.
Search and browse all your AI coding conversations in one place. Chat Wizard aggregates session data from every major AI coding tool into a single searchable panel — directly inside VS Code. No context is lost when you switch tools, workspaces, or IDEs.
Chat Wizard lets you explore, search, and analyze your GitHub Copilot Chat conversations outside the native Copilot panel. Browse sessions across all your workspaces, search by keyword or regex, export to Markdown, and inject past sessions as context into new chats.
Not locked to any single AI coding tool. Chat Wizard reads sessions from GitHub Copilot, Claude Code, Cline, Roo Code, Cursor, Windsurf, Aider, Google Antigravity, Continue.dev, Amazon Q Developer, and Gemini Code Assist — giving you a unified manager for your entire AI coding history.
Instead of asking the same question twice, search your Chat Wizard history. Find the exact code snippet, explanation, or solution from weeks ago in seconds. The Code Block Library and Prompt Library make your past AI conversations instantly reusable.

| Extension | Data Source |
|---|---|
| GitHub Copilot Chat | Per-workspace JSONL operation logs at %APPDATA%/Code/User/workspaceStorage/<hash>/chatSessions/ plus workspace metadata from state.vscdb (SQLite) |
| Claude Code | Conversation JSONL files at ~/.claude/projects/**/*.jsonl |
Cline (saoudrizwan.claude-dev) |
Per-task JSON files at %APPDATA%/Code/User/globalStorage/saoudrizwan.claude-dev/tasks/<taskId>/ |
Roo Code (rooveterinaryinc.roo-cline) |
Per-task JSON files at %APPDATA%/Code/User/globalStorage/rooveterinaryinc.roo-cline/tasks/<taskId>/ (Cline-compatible format) |
| Cursor | SQLite state.vscdb at %APPDATA%/Cursor/User/workspaceStorage/<hash>/ — chat history stored under the composer.composerData key. Requires better-sqlite3 (pre-built native module bundled with the extension). |
| Windsurf (Codeium) | SQLite state.vscdb at %APPDATA%/Windsurf/User/workspaceStorage/<hash>/ — Cascade chat history stored under the cascade.sessionData key. Reuses the same better-sqlite3 driver. |
| Aider | Markdown .aider.chat.history.md files written by Aider into each project root. Chat Wizard scans all open VS Code workspace folders plus any paths listed in chatwizard.aiderSearchRoots (up to chatwizard.aiderSearchDepth levels deep, default 3). Optional .aider.conf.yml in the same directory is read for the model: key. No central storage directory — files live inside your project repos. |
| Continue.dev | JSONL session files at ~/.continue/sessions/ (all platforms). Configurable via chatwizard.continueStoragePath. |
| Amazon Q Developer | Platform-aware path discovery (~/.aws/amazonq/ and per-platform variants). Configurable via chatwizard.amazonQStoragePath. |
| Gemini Code Assist | VS Code extension globalStorageUri for the Gemini Code Assist extension. Path discrimination prevents overlap with the existing Antigravity source. Configurable via chatwizard.geminiCodeAssistStoragePath. |
For tools with partial support, see Limited Support below.
Some tools are supported with constraints. Features that operate on prompts alone — Prompt Library, Full-Text Search, Analytics, and Timeline — work fully. The session reader displays an informational banner explaining what is unavailable.
| Tool | What works | Limitation |
|---|---|---|
| Google Antigravity | Prompt Library, full-text search, analytics, timeline, session reader (prompts only) | AI responses are not available from disk. Antigravity stores conversation content in an encrypted format that requires the running Language Server to decode. Only prompts are indexed. Configurable via chatwizard.indexAntigravity / chatwizard.antigravityBrainPath. |
- VS Code Marketplace — search for "ChatWizard" in the Extensions view and click Install.
- Manual install — download the
.vsixfile and runExtensions: Install from VSIX…from the Command Palette. - The extension activates automatically on VS Code startup (
onStartupFinished). No configuration is required for standard GitHub Copilot Chat and Claude Code installs.
- VS Code 1.85.0 or later.
- At least one supported AI coding tool installed and actively used: GitHub Copilot Chat, Claude Code, Cline, Roo Code, Cursor, Windsurf, Aider, Continue.dev, Amazon Q Developer, Gemini Code Assist, or Google Antigravity (limited support — prompts only; see Limited Support). Chat Wizard reads the session files these tools write — it does not create sessions itself and requires no additional configuration for standard installs.

See the User Guide → Commands Reference.
- All processing is local. Chat Wizard never makes network requests. No session content, metadata, or telemetry is ever transmitted to any external server.
- Read-only access. Chat Wizard reads AI chat session files but never writes to them or modifies them in any way.
- Live index updates. A
FileSystemWatchermonitors the session directories and rebuilds the affected index entries whenever new sessions are created or existing ones are updated. All views refresh automatically. - No external indexing dependencies. Full-text search uses a custom in-memory inverted index. Similarity clustering uses trigram scoring. Analytics use local token-count approximations. No ML models, no network calls.
- MCP server — local and auth-gated. When enabled, the MCP server binds exclusively to
127.0.0.1(never0.0.0.0). All requests require a bearer token generated withcrypto.randomBytes(32)and stored in VS Code's extension storage. The token is never logged. A/healthendpoint is intentionally unauthenticated so clients can verify connectivity; it returns only{ status: "ok", sessions: N }. - Local telemetry (opt-in). If
chatwizard.enableTelemetryis enabled, usage events are appended to a JSONL file inside the extension's VS Code global storage directory on your local machine. This file is never read by any external service.
- Copilot Chat session parsing reconstructs conversation state by replaying an append-only operation log. Very large sessions (hundreds of messages) may take slightly longer to parse on first index build.
- Claude Code epoch sessions — sessions with a creation date of 1970-01-01 (epoch) or with zero messages are silently skipped during indexing. This matches Claude Code's own behavior of writing placeholder files before sessions are populated.
- Token counts are approximations. Chat Wizard uses character-based counting (characters / 4) for Claude and Google Antigravity (Gemini) sessions, and word-based counting (words x 1.3) for Copilot/GPT sessions. These figures are estimates and will not exactly match the billing token counts reported by the respective providers.
- Cursor and Windsurf schema stability. Both IDEs store chat data in private SQLite databases whose internal schema can change in any update without notice. Chat Wizard targets the current schema; a future Cursor or Windsurf release may require a matching Chat Wizard update before sessions from those sources are visible again.
- Three new sources — Continue.dev, Amazon Q Developer, and Gemini Code Assist. All three participate in search, analytics, archive, and MCP.
