Relta is a Python library for building accurate and secure natural language interfaces to relational data. For example, you can use Relta to:
- Set up chat interfaces on your SaaS using assistant-ui
- As a tool call in a LangChain or OpenAI Assistant API agent
Relta has these key features:
- High Accuracy: you define the set of metrics from the underlying datasource. Relta will answer questions from those metrics reliably and nothing else. You do not need to train a model.
- Per-user sandboxing: Relta automatically creates sandboxed in-memory databases per user, so no LLM-produced SQL is ran against your production database.
- Easy feedback: when users provide feedback, Relta automatically raises a PR to fix the metrics on your GitHub repository.
Relta currently works with Postgres, MySQL, CSV, and Parquet data.
