Text2SQL.ai is a free AI tool that generates SQL queries in seconds to improve skills and save time. It uses the openAI GPT-3 Codex model to translate English prompts to SQL queries and supports various SQL dialects. While the tool is advanced and helpful, results may not always be accurate. It’s ideal for beginners or professionals who want to learn or improve their SQL skills. There are also paid plans for a better user experience, but text2sql.ai remains completely free to use.
