What our research says

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

Text2SQL.ai

A cheap, narrow utility for analysts and backend devs who write occasional SQL against schemas they did not design. If your team already pays for a coding assistant or a warehouse-native copilot, you almost certainly have this feature already.

Pros

schema upload makes output usable against real column names instead of generically shaped
explain and optimise modes are as useful as generation itself for code review
desktop app on all three OSes keeps schemas off the vendor's servers
API is priced transparently per request rather than through opaque credits

Cons

the pricing page renders client-side and third-party listings disagree on the tiers, so verifying cost takes a support ticket
no company name, team page or jurisdiction anywhere on the site, which matters when you are uploading schemas
scope is narrow: it writes SQL, it does not run or manage your analytics
API is throttled to 100 requests a month before per-request charges kick in
