From late June 2025 until late July 2025, we would like to have 50-100 people act as "beta testers" for the new AI/LLM features at English-Corpora.org. And there's no obligation at all, if you decide not to be a beta tester between now and when that starts in late June. (Details)
You would need to purchase your own "AI credits", but the charge for the AI-based queries will be just half what it would be after the beta period. So if you purchase $4.95 in credits, for example, that would give 500-1000 AI-based searches during the beta testing period, rather than the normal 250-500 searches. In addition, unused credits will remain active even after the beta testing period has ended. As with premium licenses, payment will be via credit card at PayPal (or via AliPay or WeChatPay in China).
The advantage of being a beta tester, of course, is that you will have access to these exciting new features before they are publicly available. In addition, your feedback and comments will help to improve English-Corpora.org for hundreds of thousands of future users!
