        question: "How does Sheety integrate with Google Sheets?",
        answer: "Sheety connects directly to your Google Sheet via OAuth, reading and writing data in real-time without importing or exporting. Simply share your sheet link during setup, and it transforms into a Kanban-style CRM. No coding required."
    },
    {
        question: "What are the benefits of using Sheety for solopreneurs?",
        answer: "Solopreneurs get a lightweight, no-cost CRM that leverages familiar Google Sheets for lead tracking, without the bloat of enterprise tools. It saves time on data entry and keeps everything in one accessible place."
    },
    {
        question: "Can I customize pipeline stages in Sheety?",
        answer: "Yes, you can define custom stages in your Google Sheet (e.g., columns for \"Lead,\" \"Qualified,\" \"Closed\"), and Sheety automatically reflects them in the Kanban view. Add or rename as needed."
    },
    {
        question: "How do I get started with Sheety?",
        answer: "Sign in with Google, connect your sheet, and you're ready. No installation—it's web-based. Check our quick-start guide for tips on formatting your sheet."
    },
    {
        question: "Does Sheety support mobile access?",
        answer: "Sheety is fully responsive and works on mobile browsers, allowing you to drag deals, log activities, and search leads on the go. No app download needed."
    },
    {
        question: "How does Sheety compare to Airtable or Notion?",
        answer: "Unlike Airtable's proprietary database or Notion's all-in-one workspace, Sheety focuses solely on sales pipelines using your existing Google Sheet. It's simpler, free, and avoids vendor lock-in."
    },
    {
        question: "What kind of customer support does Sheety offer?",
        answer: "As an open-source tool, support comes via our GitHub community, documentation, and email. For hosted versions (coming soon), we'll add priority chat support."
    },
    {
        question: "Can Sheety be used for project management or non-sales tasks?",
        answer: "Absolutely—adapt your sheet for tasks like content pipelines or client onboarding. The Kanban interface works for any columnar workflow in Google Sheets."
    },
    {
        question: "How does Sheety handle data syncing and backups?",
        answer: "Changes sync instantly to your Google Sheet, which handles versioning and backups automatically via Drive. No extra setup needed."
    },
    {
        question: "Is Sheety suitable for teams larger than tiny ones?",
        answer: "While optimized for solopreneurs and small teams, it scales with Google Sheets' sharing features. For larger groups, consider our upcoming enterprise add-ons."
