Privacy-First Grammar Checker for Chrome
LexiLint keeps spell checking on your device. If you start an optional AI grammar check, the extension sends the page's visible text directly to the provider you configured. Ignite App does not receive or store the page text.
🤖 New: LexiLint for AI Assistants
Use LexiLint's spell and grammar checking directly in Claude Desktop, Cursor, OpenAI Codex and other AI assistants that run local Model Context Protocol (MCP) servers.
How LexiLint Handles Page Text
Spell Check Stays on the Device
LexiLint compares visible page text with the selected dictionary inside the extension. The spell-check operation does not upload page text.
AI Grammar Goes to Your Provider
If you start a grammar check, the extension sends the page's visible text directly to the provider configured with your API key. Review that provider's privacy policy and terms before enabling the feature.
No Extension Usage Analytics
The current extension does not include usage analytics or remote error reporting. The igniteapp.net website uses Google Analytics; payments, licensing, and support have separate data flows.
Keys Stored in Your Browser Profile
Provider keys are stored through Chrome's extension storage API and are not sent to Ignite App. Protect access to your device and browser profile.
