QuantLogix offers Chromium browser extensions, including the official AI Stock Signals toolbar extension and the QL Everywhere cashtag hover extension. These extensions may request local storage for settings and permission to contact quantlogix.ai to retrieve scores, quotes, or account-linked watchlist data you choose to connect.
QL Everywhere detects explicit $TICKER cashtags on pages you visit and sends only those ticker symbols to QuantLogix for scoring. It does not upload page HTML, form fields, passwords, or your full browsing history. You can disable Everywhere per site from the extension popup. Optional account pairing for the official toolbar extension uses a short-lived code you initiate from QuantLogix.
When you connect an AI client (for example Claude, Cursor, or Claude Code) to the QuantLogix MCP server at https://quantlogix.ai/api/mcp, QuantLogix processes an OAuth 2.1 authorization so the client can call tools on your behalf within your subscription tier. You can revoke the session. API keys (ql_…) are an alternative credential for headless use. Tool calls may include tickers and prompts you supply through the client; see also the API documentation at /api-docs and /mcp-docs.
