etterGeographic filter parsing for LLMs

Transform natural language location queries into structured geographic filters — multilingual, streaming-ready, LLM-agnostic.

Geographic Filters Only

etter extracts spatial relationships from queries and ignores everything else. Feature and activity identification is your application's job.

Parse queries in English, French, German, Italian and more. The LLM handles language — you handle the map.

Containment, buffer, ring, one-sided bank, erosion, and 8 directional sectors — all with sensible defaults and full override support.

Real-time reasoning events let you build responsive UIs that show progress as the query is being parsed.

Works with any LangChain-compatible model — OpenAI, Anthropic, local models via Ollama, and more.

Fully typed structured output with confidence scores. Integrates naturally with FastAPI, SQLAlchemy, and the rest of the Python ecosystem.
