Safe Text-to-SQL for Agents

Give agents full access to your SQL database without the worry

Catch-Phrase gives agents controlled, hallucination-free natural language access to databases. So agents can ask questions or issue update commands with confidence that only correct SQL will ever be executed over the database.

Accurate


100% Accuracy Guarantee

for questions and commands within the semantically tractable class

Verified Results

Always signals when a question or command is interpreted flawlessly (i.e. it is semantically tractable)

Read this paper for a description of the semantically tractable class and how accuracy is guaranteed.

Batched Operations

Earlier key questions can be grouped into sets that can executed in batch with perfect repeatability.

Question sets can, for example, check data integrity, queue work tasks, or get a pulse on overall business state.

Intelligent Fallback

The system clearly indicates when determinism transitions to probabilities.

Candidate LLM prompts generated when a question or command is not semantically tractable. No silent failures, no undetected hallucinations.
Controllable

Fully under your control

Every behaviour is configurable.

Guarded Access

Catch-Phrase stands between the agent and the database.

No uncontrolled evaluation of arbitrary SQL over databases. No need to open database ports for remote access.

Fully Configurable

Can be configured for practically any specific semantic layer, data idiosyncrasy or permissions setup.

Comprehensive documentation covers all configuration options and deployment patterns.

Linguistically Extensible

Can attach arbitary words, phrases and documentation strings to your database elements

Provide more context around the actual data in your database to better help Agents navigate your data.

All configuration is open and inspectable. No lock-in.
