== Frequently Asked Questions ==

= Do I need to register or create an account? =
No. The free trial starts instantly with one click. For BYOK mode, just paste your OpenAI API key.

= Is there a free option? =
Yes. 25 free trial tokens are included with no registration. After that, use your own OpenAI API key for unlimited free generations, or upgrade to Pro for advanced features.

= Which models are supported? =
GPT-4.1 Mini (Trial & BYOK), plus GPT-4 Turbo, GPT-4.1, and GPT-4o in Pro mode.

= What data leaves my site? =
Only minimal context: post/term title, excerpt/description, current slug, optional focus keyword, your domain and site URL, selected model, and your Site Key. In BYOK mode, data goes directly to OpenAI and nothing is sent to RankPilotAI.

= Will Auto-Slug break existing URLs? =
When enabled, the new slug replaces the old one and WordPress stores the previous slug in `_wp_old_slug`, serving an automatic **301**.

= What is the difference between Trial, BYOK and Pro? =
- **Trial:** 25 lifetime tokens, GPT-4.1 Mini only, single generation only.
- **BYOK:** Unlimited single generations with your own OpenAI API key, GPT-4.1 Mini.
- **Pro:** Bulk generation, auto-slug, custom prompts, all models (GPT-4 Turbo, GPT-4.1, GPT-4o), index/noindex control, priority support, multi-site licenses.

= Does it replace my SEO plugin? =
No. You can keep your existing SEO plugin. This plugin focuses on fast, consistent AI generation and outputs its own meta tags.

= Works with custom post types and WooCommerce? =
Yes - any public post type, plus common taxonomies such as category, post_tag, product_cat, and product_tag.
