Frequently Asked Questions
How accurate is Co.Actor Fact Checker?
Co.Actor uses multiple AI models (Google Gemini, Claude by Anthropic) and real-time web search via Perplexity Sonar to verify claims. Each verdict includes a confidence score (0-100%) and source links so you can verify independently. While highly accurate, we recommend using it as a starting point for important decisions.
What counts as one fact-check?
One fact-check is a single verification request that can include up to 10 factual claims. When you select text, our AI extracts and verifies 3-10 facts in one request - all for a single credit. This means 20 free monthly checks can verify up to 200 individual facts!
Do unused free credits roll over?
Free credits (20/month) reset at the beginning of each calendar month and do not roll over. However, purchased credits never expire - they remain in your account until you use them.
What's the Unlimited plan about?
The Unlimited plan ($4.99/month) allows you to use your own API keys from OpenRouter and Perplexity. You pay Creative Content Crafts Inc. for platform access and pay the AI providers directly for usage. This is ideal for power users who want full control over their costs and unlimited fact-checks.
How much does Co.Actor Fact Checker cost?
Co.Actor offers three pricing tiers: Free (20 checks/month, $0), Pay As You Go ($0.02 per check with bulk discounts up to 30% - 100 credits for $2, 500 for $8, 1000 for $14), and Unlimited ($4.99/month with your own API keys). All plans include access to all AI models and source citations.
