GhostTyper shows AI writing suggestions inline as you type — anywhere in your browser. Press Tab to accept. Zero backend. Zero telemetry.
Composing an email…
Injects into every text input, textarea, and contenteditable field on any website — Gmail, Notion, Twitter, forms, code editors.
No backend server. Text goes directly from your browser to your chosen AI provider. Nothing passes through our servers because there are none.
Pollinations is the default provider — no API key, no sign-up, works immediately after installation.
Pollinations, Groq, Cerebras, Gemini, OpenRouter, Mistral, or any OpenAI-compatible custom endpoint.
Block GhostTyper on specific domains — password managers, banking sites, or anywhere you prefer no suggestions.
Built on Manifest V3 — the modern extension standard. No deprecated APIs. Compatible with Chrome, Edge, Brave, Arc.
Download the release zip, unzip it, and load unpacked in Chrome (or compatible browser). No store required.
GhostTyper detects your text fields automatically. After a short debounce (default 500ms), it fetches a suggestion from your provider.
The suggestion renders inline in grey — just like GitHub Copilot. Keep typing to dismiss or press Tab to accept instantly.
Open Settings to switch provider, add an API key, or point GhostTyper at a custom OpenAI-compatible endpoint.

Each provider has a free console. Visit console.groq.com, aistudio.google.com, cloud.cerebras.ai, openrouter.ai, or console.mistral.ai. Sign up free, generate an API key, and paste it in GhostTyper Settings.
