AI2SQL
Useful for analysts and product people who read SQL but do not write it fluently, especially against dialects they touch rarely, and the Pro plan's live read-only connection means you check the answer, not just the query. The October pricing is friendlier than before: database connections and the desktop app now sit on the $19 Pro plan, and a small free plan exists. If your team already pays for a coding assistant or a BI tool with a natural-language layer, this is a duplicate line item.
Pros
- Ten dialects including Snowflake, BigQuery, Redshift and MongoDB
- Read-only enforcement at the gateway rather than trusting the model
- Desktop connector reaches localhost and private-network databases
- MCP server works from Claude, ChatGPT and Cursor on every plan
- One-time lifetime option for people who dislike subscriptions
Cons
- The $9 Start plan caps you at 100 queries a month and cannot connect your own database
- Free plan is limited to 3 queries a day on a demo database
- Trials require a card
- Company ownership and location are not disclosed on the site
