Frequently Asked Questions About AI Content Generation

What is Luminari AI?

Luminari AI is an AI content generation platform that creates blog posts, emails, ad copy, SEO articles, product descriptions, landing page copy, and press releases. It offers a free tier with 5,000 words per month, a web dashboard for non-technical users, and a developer-friendly REST API for programmatic content generation.

How does AI content generation work?

AI content generation uses large language models (LLMs) to produce human-quality text from a prompt. You select a content type (blog post, email, ad copy, etc.), provide your topic and desired tone, and the AI generates optimized content in seconds. Luminari uses Claude Sonnet by Anthropic for paid plans and open-source models for the free tier.

Is Luminari AI free to use?

Yes. Luminari AI offers a completely free plan with 5,000 words per month and access to 3 content types: blog posts, marketing emails, and social media posts. No credit card is required to sign up. Paid plans start at $29/month for 100,000 words and access to all 8 content types including SEO articles, ad copy, and landing pages.

Does Luminari AI have an API for developers?

Yes. Luminari provides a REST API with API key authentication (keys prefixed with lum_). Send a POST request to /api/v1/generate with your content type, prompt, and options. The API returns generated content, word count, model used, and usage stats as JSON. API access is included in Pro ($29/month) and Enterprise ($99/month) plans.

What AI models does Luminari use?

Free tier uses Qwen 2.5, a fast open-source model optimized for content generation. Pro and Enterprise plans use Claude Sonnet by Anthropic, which produces premium-quality, human-like content with better tone control, SEO optimization, and factual accuracy. If Claude is temporarily unavailable, the system automatically falls back to the open-source model.
