Overview
Catch-Phrase gives AI agents controlled, hallucination-free natural language access to SQL databases. Whether your agents need to query data or issue update commands, Catch-Phrase ensures that only correct, verified SQL is ever executed, backed by a 100% accuracy guarantee for questions and commands within the semantically tractable class.
Why Catch-Phrase? Traditional LLM-based Text-to-SQL approaches are probabilistic by nature and they can silently produce wrong queries with no warning. Catch-Phrase is different. It always signals when a question or command has been interpreted flawlessly, and clearly indicates when it hasn't. No silent failures. No undetected hallucinations.
Highlights
- Hallucination-Free SQL Execution: The only text-to-SQL solution with a 100% accuracy guarantee for semantically tractable questions and update commands. Catch-Phrase always signals when a question is interpreted flawlessly, and clearly flags when it isn't. No silent failures, no wrong queries slipping through.
- Full Control Between Agent and Database: Catch-Phrase acts as a secure guardrail, ensuring no uncontrolled SQL is ever executed. Fully configurable for any semantic layer, permissions model, or complex schema and deployable on your own AWS infrastructure to meet any security or compliance requirements.
- Seamless Integration, No Lock-in: Connect via MCP Server, REST API, or point-and-click UI. Supports PostgreSQL, MySQL, SQLite, Oracle, SQL Server, Snowflake, and Redshift. Built on open XML and JSON standards. No data movement, no model training, no vendor lock-in.

Dimensions summary
You pay by the hour based on the EC2 instance size you run. All 16 dimensions bill the same software on the same usage model — the only difference is the compute size of the underlying instance. Smaller instances like t3a.micro, t2.small, and t3.medium suit lighter workloads, while larger sizes such as t3.2xlarge and t3a.2xlarge provide more compute. Pricing scales with the instance you choose, so you match cost to the capacity you need. Seats are unlimited and there are no per-question charges regardless of which instance you select.
Top-of-mind questions for buyers
Each hour covers the software running on one EC2 instance of the size you pick. Charges accrue per running instance-hour. Seat count does not affect the price, since seats are unlimited. Questions asked through the interface are not metered, so cost tracks only running time and instance size.
Hourly software charges apply only while the instance runs. A stopped instance stops accruing software fees. Underlying AWS storage costs may still apply for stored data, but the software meter counts running time only. Cancel anytime to stop charges.
No. There are no per-question charges and no per-user fees. Cost depends only on which instance size you run and how many hours it runs. Connecting to relational databases through the server does not add metered charges. Your bill tracks compute time, not query volume.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources.
